That's my own DIY SteadyCam, like others that you can found at the web, but not completely conventional ... </div>
<div style="text-align: justify;">
The origin of this project was to intend for obtaining stabilized footage riding a mountain bike. What about a steadycam that doesn't need use one hand to frame?</div>

That is a column-type steadycam, but there are arch-type models, more simple and less professional, that works in a very similar manner: like this <b><a href="https://vimeo.com/4034560" target="_blank">MERLIN</a></b> or <b><a href="http://cheesycam.com/canon-t2i-camera-stabilizer-video/" target="_blank">THIS ONE</a></b> more simple.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Next some photos of joint (or kneecap / swivel) that provides independence from movement for two axis.<br />
The movement for the thirth axis (rotation around Z axis) was solved with a bearing whose friction is Significantly higher that kneecap, but permits to implement the "one hand" system,</div>

<b>ONE HAND</b></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
All the steadycams that I know have to be handled with two hands: Usually one hand for support the weight of the steadycam and other hand to aim or frame the image, gently, using very little force for not disturbing its working principles.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
My modest contribution is that two rubber bands are used to mantain (gently) the camera pointing at front. Now the steadycam only stabilizes the fast and short angular movements, but not the smooth and permanent movements. And is possible to frame pointing with the same hand that holds the handle.<br />
<br />
</div>
<div style="text-align: justify;">
</div>
<iframe allowfullscreen="allowfullscreen" frameborder="0" height="675" mozallowfullscreen="mozallowfullscreen" src="http://player.vimeo.com/video/48918497?title=0&byline=1&portrait=1" webkitallowfullscreen="webkitallowfullscreen" width="600"></iframe> <br />
<a href="http://vimeo.com/48918497">SteadyCam -one hand-</a> from <a href="http://vimeo.com/jelmetcam">montonm</a> on <a href="http://vimeo.com/">Vimeo</a>.<br />
<br />
The video in not a comparison between two similar recordings with or without steadycam.<br />
<div style="text-align: justify;">
The sample without stabilization (upper) only intends to show how the violent shaking on the handle of steadycam does not avoid that final result is acceptable enough.<br />The swinging up-down seems well solved and equally the oscilation side-to-side. But the rotation around z-axis is less smooth due the higher resistance to movement of bearing.<br /><br />I hope to do some test with the steadycam on the bike... (not too esasy). I promise to report.</div>

The Camera has some features that I like:<br />
- Both, camera and case, have threads for tripod.<br />
- It's small, but includes LCD screen to view when recording or playing back.<br />
- The waterproof case has the same 6 function buttons that the camera, and you can operate all funtions alike with or without it. You will never need to open the camera on the trail.<br />
- The lens is interchangeable. Well done!... but only one is included in the box.<br />
- There are two micro SD slots.<br />

Unfortunately, not everything fits well:<br />
- The side cover to protect connectors and cards is crappy and does not close<br />
- It is hard to put the camera inside the case. It fits too exact<br />
- The LED that indicates operations is just behind the rim black, and can not be seen !</div>
<div style="text-align: justify;">

Quality of mount system is similar to GoPro ones, but they are not compatible.</div>

Bitrate values are aproximate, they are obtained setting the "high" mode. (there are three options: H, S, and L).<br />
The same modes are in PAL too, (at 24 fps). But I have not tested them.</div>
<div>
The battery life lets me to record 1 h. 43 min, and to recharge is fast enough.<br />

<b>Lens angle</b></div>
<div>
As ever, no manufacturer publishes understandable and true informatio about view angles. The next data are measured and calculated by me:</div>

</div>
<div style="text-align: justify;">
Briefly, at 1080p mode, the angle view is a bit more narrow that GoPro, but at 720p mode is a bit wider.<br />
The following video shows differences between angle view at different modes:</div>

<div style="text-align: justify;">

<div style="text-align: justify;">
At 720p mode is possible to use the zoom function, but this feature is completly useless for on-board purposes: when camcorder stops and starts again the zoom fits itself to maximum wide.</div>

<b>Testing on ride.</b></div>
<div style="text-align: justify;">
</div>
For test the camera I place it on my improved "chesty", fortunately...<br />
The CamOne designers did not implement any "beep" (The CamOne Infinity do not emit any sound, it has not speaker). They did not think of putting a swich instead a push button... and the small size and feeling are not appropriate for using with long gloves.<br />
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
</div>
In the chest-mount the camera is at sight, but is almost impossible to see blinking the LED to know if the camera is recording or not. If you put your CamOne on the helmet you can not to know if it is working !!!<br />
<br />
<iframe allowfullscreen="allowfullscreen" frameborder="0" height="338" mozallowfullscreen="mozallowfullscreen" src="http://player.vimeo.com/video/45336181?title=0" webkitallowfullscreen="webkitallowfullscreen" width="600"></iframe> <a href="http://vimeo.com/45336181">Bicuerca - CamOne Infinity 1080p test</a> from <a href="http://vimeo.com/jelmetcam">montonm</a> on <a href="http://vimeo.com/">Vimeo</a>.<br />
<br />
On the good side the camera has a very good performance for measuring the light exposure. I think that is better (or more properly, less bad) that GoPro, Contour, etc... and the rest of POV cameras that I have tested. The CamOne Infinity is not mistaken easily when a portion of a bright sky comes into the frame.</div>
<div style="text-align: justify;">
<br />
The colour feels something subdued and the image has a low contrast... but that can be improved in the edition process. The sample video shows the latest seconds of each secuence with filters to increase contrast, colour saturation and lights the shadows. The rest of time the images are as coming out of the camera.<br />
<br />
On the negative side all footage seem some blurry. As slighty out of focus, but I have not been able to correct it by screwing or unscrewing the removable lens...</div>
<div style="text-align: justify;">
</div>
<div style="text-align: justify;">
Sound is really bad (like others cams with waterproof case)<br />
<br />
<iframe allowfullscreen="allowfullscreen" frameborder="0" height="338" mozallowfullscreen="mozallowfullscreen" src="http://player.vimeo.com/video/48100456?title=0" webkitallowfullscreen="webkitallowfullscreen" width="600"></iframe> <a href="http://vimeo.com/48100456">El Campillo</a> from <a href="http://vimeo.com/jelmetcam">montonm</a> on <a href="http://vimeo.com/">Vimeo</a>.<br />
<br />
This second video confirms the first impression about good performance in hard lighting scenes (backlight, bright sky, sun in the frame...). All footage are filtered with same settings.</div>

<a href="https://picasaweb.google.com/lh/photo/PGU1Y8DhsTlMIs5Jh235DyP9OJVPoGU2SFXy1_NTKfQ?feat=embedwebsite"><img height="401" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjBr_HVKYD8cSppkZoJn_Lwb0mVoVPth3w8cbWyFMap52RFZWHiPb7rDUcHCcbpSJcg4EAGVn4vBhSyhA0hlkmurEnn3d4nDyS-AIbgceywBIRbC3r8M6oyxLBnRVSh9LpuoldIdofeieE/s800/accesorios%252520h_web600.jpg" width="600" /></a><br />
<br />
<div style="text-align: justify;">Camera; Battery; Waterproof case; TFT screen backpack; Wireless remote control; clamp for remote control; 2 adhesive flat mounts; 1 adhesive curved mount; 3 articulated arms; Charger; USB cable; audio-video cable; Bag.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><b>How works all that.</b></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">For recording video the main unit is enough. It has its own push buttons for taking photo and for start/stop video recording. A switch on/off and another switch called 'VOX' to activate the start/stop function by sounds.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The remote control is not essential. Only is usefull on mountings in that you don't reach the buttons. It is necessary for to activate the laser pointer for a while.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The screen backpack let you to watch that you are recording or to play video. Is not necessary to carry it, but is the only way to change the setting (video mode or other settings)</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Inside the waterproof case only fits the main unit, not the screen backpack. The two push buttons are functional, but not the two switches.</div><div style="text-align: justify;">The case has a flat lens protector (unlike the GoPro). Seems tha there are two types: The case that I have tested and another with dismountable lens protector. The unit tested makes the laser pointer totally unfunctional (the ray aims to the opaque circle around the lens...)</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The mount pieces are very similar to the GoPro ones but not equals. You can mix arms from both brands forcing them, but not the mount pieces.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The main unit and the waterproof case are gifted with universal screw for tripod.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><b>Video modes.</b></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The camera has 5 video modes:</div><div style="text-align: justify;">1080p 30 fps (1920 x 1080) 16:9</div><div style="text-align: justify;">960p 30 fps (1280 x 960) 4:3</div><div style="text-align: justify;">720p 60 fps (1280 x 720) 16:9</div><div style="text-align: justify;">720p 30 fps (1280 x 720) 16:9</div><div style="text-align: justify;">XWGA 30 fps (1080 x 480) 16:9</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">That is a test to compare the angle view in every mode:<br />
</div><iframe allowfullscreen="" frameborder="0" height="450" mozallowfullscreen="" src="http://player.vimeo.com/video/32111272?title=0&byline=0&portrait=0" webkitallowfullscreen="" width="600"></iframe><br />
<br />
<div style="text-align: justify;">720p and XWG modes have the same angle view and 960p keeps the same width but surprisingly the 1080p mode reduces notably the view field.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The Maths indicates the next:</div><div style="text-align: justify;">AEE SD20 1080p h. angle: 78º diagonal angle 85º</div><div style="text-align: justify;">AEE SD20 720p h. angle: 106º diagonal angle 114º</div><div style="text-align: justify;">AEE SD20 960p h. angle: 106º diagonal angle 118º</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">As ever, nothing is like manufacturers pretend, (not in this camera but either that I have tested).</div><div style="text-align: justify;">For comparative purposes, next I show the trigonometrical results for other well-known cameras:</div><div style="text-align: justify;">GoPro HD HERO 960p h.ang: 120º diagonal angle: 130º</div><div style="text-align: justify;">GoPro HD HERO 1080p h.ang: 103º diagonal angle: 111º</div><div style="text-align: justify;">GoPro HD HERO 720p h.ang: 120º diagonal angle: 126º</div><div style="text-align: justify;">Contour 1080 HD 720p h.ang: 97º diagonal angle: 105º</div><div style="text-align: justify;">Contour 1080 HD 960p h.ang: 97º diagonal angle: 110º</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><b>First tests.</b></div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Here you can see some footage, with original audio and without edition work.</div><div style="text-align: justify;">The camera was mounted in an improved chest cam, that keep in place the camera correctly, without stability problems. No waterproof case reducing the sound. Video mode was 720p to 60 fps, with 'slowmotion' samples at the end.</div><div style="text-align: justify;">I have used a microSD Kingston class 4 without any problem. The bitrate results about 7.900 kbps.</div><br />

<br />
<div style="text-align: justify;">Beside the impressive landscapes, good footage selection, and the great work mixing them with music, the most important success is due the diverse and innovative points-of-views that Philip uses to take the shots.</div><br />
<div style="text-align: justify;"><b>"Propeller head"</b></div><br />
<div style="text-align: justify;">Is not the first time that this device runs in the web, but the results are specially good using it moderately and mixing it with other shots.</div><br />

<br />
<div style="text-align: justify;">The system is simple. Philip describe how he do it:<br />
<i>"I used a plastic chunk cut to allow me to velcro it to my helmet using the vents, and on top of that I used a spare Heim chain guide roller. Bolted to that I have an aluminum plate that I can hose-clamp some rod or dowel to. I used a 1/2" wooden dowel first, but I promptly broke that. Now I have some cheap WalMart tent pole sections. They flex and bounce, so some stiffer tubing would probably help, but I can take the two sections apart and the pole ends up half as long so I can pack it around. The camera is mounted on one end via the GoPro seatpost clamp mount, and I have a 12 oz fishing weight taped to the other end for "balance." I actually have the rig set up slightly camera-heavy so I can position it somewhat by leaning my head. The whole thing is a bit of a millstone and your helmet had better fit pretty tight!"</i></div><br />
<b>Cable-cam</b><br />
</div><div style="text-align: justify;">This 'simple' cable-cam contrasts with the sophisticated system MirloCam by Emilio Avila. But results are vey interesting too. First the how-to-do video:</div><div style="text-align: justify;"><br />
<iframe frameborder="0" height="308" src="http://player.vimeo.com/video/15046586?title=0&byline=0&portrait=0" width="410"></iframe><br />
<br />
<i>The shuttle is a length of plastic that I simply bolted a RAM ball mount to, and on either end is a small pulley. I dremeled a slot in one side of each pulley so I could slip the shuttle on and off the fishing line. The line itself is a spool of 300 yards of 100 pound test dacron halibut line. I put a dowel through the spool secured on either side so it would spin on the dowel, and I put a small bolt through one flange so I could crank the spool and take the line up again quickly when I am done.<br />
<br />
The line has an eye in its end that I have put a basic metal snap on. A couple of feet up the line is another eye. This is so I can loop the end of the line around a tree or branch and put the snap through the second eye and secure the end of the line without having to tie a knot. A couple of feet further down the line I have a short length of bungie attached that has a plastic washer on its end. The washer does not fit through the pulleys, so as the shuttle runs along the line and then along the line and bungie, the bungie stretches and acts as a soft stop. I spool the line out to another tree and give the line about 10 wraps around a branch. That seems to offer enough friction to hold the whole mess </i><br />
<br />

<div style="text-align: justify;"><b>Other bike clamps</b></div>Other shots was taked from diverse positions from bicycle, helmet, chest and a pole with camera at the end, (my favourites).<div style="text-align: justify;"><i>On-bike scenes were generally done using RAM mounts. gpscity.com has an excellent selection of RAM stuff. I use the 1" ball head metal system ('B' size). The plastic RAM stuff flexes too much. I use them with a GoPro, but a Contour HD is pictured here:</i></div><div style="text-align: justify;"><br />

</div><div style="text-align: justify;"><i>For the ground-skimming shots I just used a pole similar to the propeller head contraption, but I just hold it in my hand and either ran or rode behind Barny and held the camera a few inches off the dirt as we moved along.</i><br />

Stuff enough for inspiration... is not?<br />

It is not difficult when you places the camera in the helmet: Once the position is verified, all you had to do is to maintain your head an point to straight.<br />
The problem is bigger on chest-cam assembly, because the angle of trunk is variable depending ride situations. Unavoidably. </div><br />

<br />
<div style="text-align: justify;">I recommend you to see the next videos in Vimeo:</div><a href="http://vimeo.com/12394951"><b>"Nomadas vol.1"</b></a><br />

<br />
<div style="text-align: justify;">Ian himself tell us some words about his videos, (I'll try translate them to my poor english):</div><br />
<div style="text-align: justify;"><i>Generaly, If I go out without determination to record, I usually carry with me only the GoPro HD with several mounts, and a little tripod with a mending to fit GoPro to tripod screw. If I go out determinated to record some video, I also carry with the big camera, a CANON HFS200 and a wide lens angle 0.45x and some filters, and a more stabile tripod.</i></div><br />
<div style="text-align: justify;"><i>In my opinion, for a good results, You must have diverse shots, fixed shots, point-of-view shots from helmet, zooms, far shots, close ones, etc... and a previous idea about you want edit before going out to record the necessary shots.</i></div><br />
<a href="http://picasaweb.google.com/lh/photo/wcZtKDGVeOrPQv8Y0rL3ViP9OJVPoGU2SFXy1_NTKfQ?feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrsfNrrWx2vl2_zLCcB5EFfCw-690xFEDM3FU2abh0j2ybYIU_ZE5bCtJ5FCb00aktyxyleDljmuORh0y6Elq1_DO0x0NKm0XaGeVyfZmvbeAaS4_jIhyphenhyphenhMI94RVYJ3m4uIM538jhnbis/s800/IanBaquerin3web600.jpg" height="800" width="600" /></a><br />
<br />
<div style="text-align: justify;"><i>About subjective (POV) shots, I try to vary and to look for new shots, I try to watch videos enough on the web to take ideas: helmet, frame, chest, pole from helmet, etc. I try not to buy too many mountings but I try to make up them, cheap materials and sticky tape...</i></div><br />
<div style="text-align: justify;">Unquestionably the final results, joining together every assorted shots, looks very well. Another matter is the (I suspect) great difference between a 'normal' ride with a simple helmetcam and a 'filming' ride ... but I'll do it someday... I'll tell you.</div>montonmhttp://www.blogger.com/profile/04238064091186100165noreply@blogger.com0tag:blogger.com,1999:blog-1003359870535576982.post-37930515690266960942010-09-06T15:06:00.000-07:002010-09-16T14:30:21.048-07:00VholdR Contour HD 1080 vs GoPro HERO HD<a href="http://picasaweb.google.com/lh/photo/jaf0hk94bXzoUqDzJV-zkSP9OJVPoGU2SFXy1_NTKfQ?feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjQ63_4ciuDm2eKwlPgi_jtPYD617jqG-slpePwiRuliQQE_V3JtqhGv-gaI5YjRQSGmoOCrhuJBhl_-by7WOeGR9jI-UMk8KMecRwimeeqWTZMXYkl25JGgFT6Pizqp8B05Tl_IMCzqD4/s800/contour%20vs%20gopro%20frontal_web600.jpg" /></a><br />

<a href="http://vimeo.com/13344297">GoPro HERO HD vs Contour 1080 HD</a> from <a href="http://vimeo.com/jelmetcam">montonm</a> on <a href="http://vimeo.com/">Vimeo</a>.<br />
<br />
The two imágenes are without any correction, editted with same software (Adobe Premiere Elements) and identical compression and codec. Both cameras are setted to 720p 60fps and light measuring at central area.<br />
<br />
<div style="text-align: justify;">But there are big differences: angle of image, sharpness (mainly at limits), global brilliance, response for changing ligthing and managing of contrast...</div><br />
<div style="text-align: justify;">Note that the most noticeable difference between footage may be dramatically improved with postedition process (not used at videos). Next you can see one frame (minute 3:08) from Contour HD, before and after that were applied some changes to 'brilliance' and 'contrast'</div><br />
<div style="text-align: justify;"><a href="http://picasaweb.google.com/lh/photo/D6c9gsUtYFpsbfl8PA940iP9OJVPoGU2SFXy1_NTKfQ?feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh5lq77BTWc7arbxXuHXx_GGM7aatlR27NjiV7zqOFU7nTxLbqg-g1yxw0jW7OSVMZqXWxMNtoGVo_2IAAetwwdz9S_r3SmHUt_wgzPgVKXd14j37QA-9b3h39dFCt7ebsnFda4X22ucLw/s800/contour%20everyday%20&%20mejorado_web600_black.jpg" /></a><br />
<br />
<div style="text-align: justify;"><div style="text-align: justify;"><b>Audio.</b><br />
You may test the recorded sounds and compare them. The GoPro Hero cam is placed inside a waterproof box: That stops the water... and sound too. There are a perforated box, but I have not tested it.<br />
<br />
<b>Configuration</b><br />
Setting GoPro cam is possible from its own menu: The menu is simple, but to navigate is a bit annoying and slow because its system is cyclical.<br />
Contour is configured when it is connected to PC, with its specific software, easy to use. The options are similar to GoPro, the resolution modes are exactly equals, but Contour lets you choose the bitrate.<br />
For fast on-road configuration the Contour camera has a simply switch to select two differents resolutions previously defined with the software.<br />
<br />
<b>Additions.</b><br />
The GoPro has photo mode, and continuous photo time lapse. I am sure all that may be useful but not for helmetcam MTB.<br />
The Contour has two laser pointers to facilitate the camera location. Good idea ... were it not because the light is only visible indoor or at night time. (at last... the only option is trial and error) <br />
<br />
<b>Battery life</b><br />
Battery life is very similar in both cameras, around 60 minutes recording at 720p 60fps and other 60 minutes switched on (aproximately). The GoPro indicates the battery level in its little screen and the Contour with a colour of a LED at rear.<br />
The bitrate of the GoPro (15.150 kbps) doubles the standard in the Contour (9.700 kbps), but Contour enables to choose two upper bitrates. A 8GB SD card is enough for record at 720p 60fps, until battery ends.<br />
<br />
<b>Mounts</b><br />
The GoPro has a good variety of mounts, for locate the camera at any place, (there are different kits including mounts for every use, and other mounts that can be bought additionaly, like 'chesty' mount.<br />
The range of mounts for Contour is more limited. The camera kit includes an adhesive mount for flat helmets and other one for goggles strap. Other mounts are additional.<br />
Placed in a helmet the Contour is less bulky than GoPro, closest to helmet.<br />
<b><br />
Managing on-board</b><br />
The Contour is clearly best at this point. The slidding switch lets you know (or remind) at every moment if recording is on or off. The 'beeps' when the Contour starts or stops recording are clearly heard.<br />
While the waterproof case of GoPro prevents you to know if the push button was correctly activated.<br />
Mount the GoPro in a place where you can not see (in a helmet...) involves some irritating wrongs for that.<br />
<b><br />
CONCLUSION</b><br />
Is not easy. I have not found reasons for prefering one to another. Both of them have some advantages.<br />
The final decission depends of specific use or your own preference.<br />
<br />
I like:<br />
... the wide angle of Contour (enough and not excessive)<br />
... the widest angle of GoPro (good for to stabilize and trim margins)<br />
... image quality of GoPro (in Contour you must postprocess for best results)<br />
... sounds in the Contour<br />
... easy managing in the Contour<br />
... fitting at helmet of Contour<br />
... fitting in every situation with the GoPro, and chesty mount (extra)<br />
... the waterproof feature in GoPro<br />

</div><div style="text-align: justify;"><b>DRIFT X170</b></div><div style="text-align: justify;">Is a not well known camera, was mounted on the top of the helmet of Ruben. Ruben follows me riding 'Los Pepes'. You can see here some extended videos.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;"><b>MiniDV MD80 "shitcam" + wide lens 0,38x</b></div><div style="text-align: justify;">The 'shitcam' was mounted on the helmet facing back. Helmet is not the best place to mount back-cameras, becouse in cornering the image moves out excessively to sides. Camelback is better place to do it.<br />
<br />
</div><div style="text-align: justify;">Definitely, the 'shitcam' has not quality enough to fill an HD format. The video comes with 30,9 fps more or less (not any standard), jumps every few frames and has a lot of wooble.</div><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">Footage from X170 and 'shitcam' fits well into little windows, but in the big one the difference with Lumix is notorious. So I decided to use short appearances and colours.<br />

<a href="http://vimeo.com/5918405">Mount Rose Meadows - Tahoe Rim Trail - POV - Great Basin Bicycles - Singletrack - Reno Mountain Bike Trail</a> from <a href="http://vimeo.com/renotahoetrails">Rich Staley</a> on <a href="http://vimeo.com/">Vimeo</a>.<br />
<br />
<div style="text-align: justify;">Really, I would not call this 'helmetcam' but all kind of on-board or subjective video riding bicycles are welcomed in this blog.</div><div style="text-align: justify;">Rich recorded his videos with a Sony lipstick camera plugged to a miniDV camcorder. The camera was holded in front of the bike frame: '<i>The clamps that I made for the bike are relatively simple. There are two clamps, one around the bottom of the head tube, and one around the top tube of the bike. They are simple circles cut in half then jointed at one end, with a bolt on the other side so that they can clam shell around the frame.

<div style="text-align: justify;">I like very much the speed sense that is transmited by this recording system. I think is due to combination of a low point of view and a narrow trail. The angle on inclination in corners adds dynamism.</div><div style="text-align: justify;">Of course this setting thrashs largely the more usual mounting in handlebar that, in my opinion is not good because of infuriating movement from side to side, mainly in slow paths</div>Here you can see one more:<br />

The wide angle conversor minimizes the shaking and the wobble (jello effect), and overall performance of the camera. It can be bought about $ 15.00. (there are cheaper and crappy ones).<br />
<br />

<div style="text-align: justify;">At next video you can see a practical demonstration of the angle lens importance, comparing the shitcam with a 28mm equivalent of a Lumix DMC FT1 (TS1)</div><br />

<br />
For references, wide angle lenses in helmetcams are GoPro Hero HD, with 170º (or 127º depending resolution) also Contour HD are 135º and POV 1.5 are 110º. All that accord their specifications offered by manufacturers (not tested).<br />
Under 70-75º it results more difficult to frame the rider in front of you. If you have planned to buy a camera for helmetcam use, should search for less than 30 mm equivalent.<br />

</div><div style="text-align: justify;">Lumix TS1 records good VGA videos: White balance, exposure and contrast are better than any specific 'helmet' cam that I know.<br />
</div><div style="text-align: justify;">Angle wide (28 mm equivalent) is enough for helmet use, it is waterproof and seems strong for outdoor sports.<br />
</div><div style="text-align: justify;">Internal stabilization works moderately good in VGA resolutions but it's not infalible. I would prefer that TS1 had the possibility to turn off the steady function. (I think that PC software would improve their results).<br />

Cycle is closing and I have retorned to similar mounting system that I had used at <a href="http://helmetcamexperience.blogspot.com/2005/11/chipiritiflautico-proyecto-1.html"><b>first experiences</b></a> about helmetcam.<br />
<a name='more'></a><div style="text-align: justify;"><br />
</div><div style="text-align: justify;">The camera is mounted at side of the helmet, and a counterweight must be placed in the other side. Light weight of the Lumix and a low center of gravity, (compared with miniDV), makes this system more comfortable and stable.<br />

<div style="text-align: justify;"><br />
In this helmet (Casco Viper MX) is easy to place the anchoring for the camera and the counterweight using the holes designed for the dismountable chinguard.<br />

The trick to lock the anchorage is to use a piece of exact thickness and a dismountable 'claw'. I have tested two different systems.<br />

<div style="text-align: justify;">I have always used stabilization software to make smoother videos of the rough and stony paths near my home. Recently I'm looking for the best software to do it.<br />
Watch too the next video:<br />

<br />
<div style="text-align: justify;">So far I have been using SteadyHand, but since stopping to use miniDV feel I need another which can operate with other codecs and HD videos.<br />
</div><div style="text-align: justify;">First video shows three stabilizers: <a href="http://www.prodad.de/gb/mercalli_std_details.html"><b>Mercalli Pro-DAD</b></a>, <a href="http://www.guthspot.se/video/deshaker.htm"><b>deShaker</b></a> and <a href="http://www.goodervideo.com/products/SH.html"><b>SteadyHand de Dynapel</b></a> in a quiet path, quite flat and easy. The second shows more active trail, not very stony but fairly swinging.<br />
To better compare I recommend watch the videos in Vimeo web. Could be usefull to mask one frame with a paper or hand.<br />
</div><br />
<div style="text-align: justify;">Perhaps it was premature, but I think deShaker works better than others, with no errors and even smoother movement with less frame oscilation. Next "long" video I will use deShaker for edit it, and see. <br />

<div style="text-align: justify;">The H.EXP 7.0 was designed thinking to put every kind of cameras in, but obviously cameras with light weight and small size makes to wear the helmet more comfortable. Recently I bought a Panasonic Lumix DMC FT1 (TS1 in USA) and I was looking for the best way to carry it on the helmet.<br />
</div><a name='more'></a><br />
<div style="text-align: justify;">These first photos show the simple 7.0 mounting system: The camera is directly screwed.<br />
</div><a href="http://picasaweb.google.com/lh/photo/mVqI8Gev8i3G2AD9_MgTFA?authkey=Gv1sRgCL6MuNmox8vATw&feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgadUAKVKfSXnj0zlYs2sY_biumqYee1Tf3PnqOE5Q4cVw_ulXdm3p7sRh4PyVG9z95_MSdTqp5hgY0zGm4WV1OF3AIgGZAaXRg-GoxOD8RqOLGXT9ER_hOssSQD8vKn7Mm0hOOUiSPTsc/s800/chiripi%2070%20lumix%20dual%20web600.jpg" /></a><br />
<div style="text-align: justify;">But placing or removing the Lumix was too slow to do on the fly. I recommend strongly insert a quick release adapter. So, the camera is ever ready for conventional use (taking photos, reading battery state or changing settings...) or on-board use. I will refer quick release systems with the mark'+' (e.g. 7.0+)<br />

<div style="text-align: justify;">At last, I prepared a set of accesories (U-bar and brackets) for to place the camera upright or in different possitions. They will be called 7.1 and 7.2. The results are very similar in all positions. Differences are the risk to hit the stem and small changes in image composition.<br />

<div style="text-align: justify;">This video is mainly intended to show capabilities of Lumix DMC FT1. It has 3 cuts in lighting conditions that usually hinder recording, and the Lumix passed positively the test. <br />
The system mounting is a variant of 7.1+ with a small U-bar that places the camera in a higher position.<br />

It is the result of operation by 'rolling shutter', opposite to 'global shutter' usual in CCD sensors.<br />
</div><object height="458" width="610"><param name="movie" value="http://www.youtube.com/v/0qC0_nIUq9s&hl=en&fs=1&rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/0qC0_nIUq9s&hl=en&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="610" height="458"></embed></object><br />
<a name='more'></a><br />
<span style="font-weight: bold;"><br />
Why?... CCD versus CMOS</span><br />
<div style="text-align: justify;">Technology of CCD sensors scan all picture in same time (all together). A CMOS sensor scans the image line by line, from top to bottom. The time used for a complete image could be up to 1/30 second and during this time the subject may have moved.<br />
</div><div style="text-align: justify;">In next video, a good quality CMOS is unable to record entire coin at same fraction of time:<br />
</div><object height="387" width="610"><param name="movie" value="http://www.youtube.com/v/LPOaH7uK9ho&hl=es&fs=1&rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/LPOaH7uK9ho&hl=es&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="610" height="387"></embed></object><br />
<div style="text-align: justify;">It is not a 'problem' about quality of the camcorder but cameras equiped with CMOS are not appropriated to record fast movements, simply. Watch this <span style="font-weight: bold;"><a href="http://www.youtube.com/watch?v=UEaDrS-yzIE">VIDEO </a></span>comparative between two identical cameras with only difference of image sensors.<br />
<br />
</div><span style="font-weight: bold;">Effect recording on MTB</span><br />
<div style="text-align: justify;">Helmetcam videos are full of shaking and sudden movements. Many raw videos seem completly trembling, so is difficult to appreciate the jello effect. But a stabilization process, (e.g. SteadyHand or Mercalli) reveals the effect. The software process is not capable to stretch or to contract the still (only can move it)<br />
</div>Next image shows two near stills (only separated by 2/30 seconds) from my latests video:<br />
<a href="http://picasaweb.google.com/lh/photo/GS2mn0RVlOJRZbudxZ18kA?authkey=Gv1sRgCL6MuNmox8vATw&feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjC-cSMKD-383ZaJb_EzPY-925Q3y6HjfxioTIJhDVP8QIzP6OwAxHO96hyR_xydkZDvjmjE6BnxlZPRj9M1yU53ggzWKIcKLV-9kLV1hG8Yml0YMTtAk4DUshGsL1nRwPU_utkxxP4mbY/s800/wobble%20graphic%20web600.jpg" /></a><br />
<div style="text-align: justify;">In first the cam is moving up, and the second the camera is moving down. The result is that image seems to contract and to stretch alternatively. In the <a href="http://vimeo.com/4314101"><b>VIDEO</b></a>, the jello effect is visible.<br />
<br />
</div>Other sample to understand the effect:<br />
<object height="424" width="610"><param name="movie" value="http://www.youtube.com/v/ii4g-PxRpuM&hl=es&fs=1&rel=0"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/ii4g-PxRpuM&hl=es&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="610" height="424"></embed></object><br />
<div style="text-align: justify;">Only a few CMOS cameras are ready to resolve the effect of rolling shutter (e.g POV 1 uses CMOS with "electronic global shutter"). In most of CMOS photo cameras and most of one-piece helmet cameras the 'wobble' can be a problem, specially if you are intending to obtain steady footage.<br />

<div style="text-align: justify;">Everytime that I start a experiment, I expect it will be the definitive. One more time, I was sure that it would be in this way.<br />
</div><a name='more'></a><br />
<div style="text-align: justify;">Theoretically, this 7.0 version should be perfect in some matters:<br />
- Impossible to hit or get tangled with branches<br />
- Fits on every camera provided with thread for tripod<br />
- Easy adjust and alignment once calibrated<br />
- Do not need counterweigh even using big camcorders<br />
Idea was to use a full helmet, and hanging the camera under the chin guard. In inverse position, for more simplicity.<br />
</div><a href="http://picasaweb.google.com/lh/photo/Gl-rUcuyzmPc2IumK3oeig?authkey=Gv1sRgCL6MuNmox8vATw&feat=embedwebsite"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjsFYWE2i4HVRS8BH9gQJ3raorEhe9TtfGDxM1qToYpD4_TbfLyPrAQorm3zoMVQSr8jhV7RvMTHq86Wi-KeMQPNXxp8r8Yc0aDqdJUFNS0gj9Ys9-UAWFJvzQs10IXdXJjNcZmJVpbvWg/s800/chiripi%2070%20reflex%20dual%20web600.jpg" /></a><br />
<div style="text-align: justify;">Work consists in inserting in the foam of the chin guard two striated aluminum bars, and fix it with epoxi glue (two compound, one of few useable with poliestyrene). The other pieces are, as usual, manufactured with saw, drill and file.<br />
Next images shows the Canon MV5 directly attached an H.EXP 7.0, in the first test.<br />

<div style="text-align: justify;">This was the first video recorded with 7.0 but it does not the best quality that can be obtained becouse a wrong selection of de-interlace options in the exporting process.<br />
The service of the mounting system was pretty good considering weight of camcorder. But now there are many cameras in the market with more resolution, quality of image and less weight than that obsolete miniDV. (like the Lumix in the first photo)<br />

<div align="justify">At next video you can see the results of this mounting. the Camera aims a little down, (only a bit: in this composition, you need to view terrain in front of the following rider). And the aluminun rod is short, definitively, I did not like to see the bag jumping ...<br />
Making the arm more long could to bother in narrow paths or low branchs, so I discarded this experiment and began thinking about the next backwards-cam.<br />

<div style="text-align: justify;">I had use a plastic flexible plate fixed with four pegs to the main straps and chest strap of a Camelback Lobo. The plastic plate is stiff enough for screwing the aluminium support of the cam.<br />
</div><div style="text-align: justify;">As usual in my systems with bullet-cam, I use a clip of bicycle pump to hold the camera.<br />
</div><div style="text-align: justify;">Vibration and shaking on resultant video are more intense than in the helmet mountings, and tilt position is difficult for to decide: the tilt for climbing is notably differenced than tilt for downhill. But, except for to put on the backpack, is the more confortable system.<br />

<div style="text-align: justify;">This is a video recently recorded by Yolucas in Andorra (Pyrenees), just when the pack begins to getting dust on its shelves. The chest position is the best for a inexperienced cameraman: You simply might forget about recording, but movie will be pretty good.<br />

<div align="justify">We continue experimenting. Now trying to put the cam in a lower position to include handlebar into the frame.<br />
</div><a name='more'></a><br />
<div align="justify">That's simple for one bullet cam: Just a aluminium rod fixed at helmet by side that down near the chest. It keep on the advantages of cam on the helmet, (stability and 'you reccord that you see') but handlebar only appears when slope is great.<br />

Not all are advantages. On ride position the cam doesn't disturbs at all, but the rod obstructs the complete mobility of neck to left side... I'll have to resolve it.<br />

<div style="text-align: justify;">Some of the more sloped paths near Castellón (Spain). Riding very slow ... to ride fast over these craggy terrain you must be very very fearless. (As usual, video does not show the true gradient of scene).<br />
