OK check out the Elmo SUV-Cam II:
http://www.elmo.co.jp/suv-cam/en/sample/download.php


Wow- WOW!

Man Elmo's website is annoying they have a bunch of sample videos yet this is the only one you can take as a download. The others display inside a stupid popup window without standard player controls and you can't fullscreen it- or even pause/start/rewind it as far as I can tell. Which makes it worthless to try to analyze it.

ah found another one:
https://www.actionvideocams.com/uplo...ORC51short.wmv

But yeah that video sure looks like 704x480 @ 25fps (as claimed) to me. When it races past the fenceposts you can see where they deinterlaced the frames (2 fenceposts near each other) and the smooth video is consistent with 50 deinterlaced fields/sec. Or I guess it may have been deinterlaced during the transcoding to the website but anyhow both fields were used.

The system has their own camera prewired into it you can't add your own. That format's essentially PAL though and that's got to be a PAL camera wired in there not NTSC. It'd be nice to have NTSC video to put on an NTSC dvd rather than converted PAL.

That's an $800 recorder/camera though, and I don't want to be tied to using their camera. I something need other lenses and don't want to be up a creek if I accidentally break the camera (or just scratch the glass).

Ah I found footage taken with that "Action Video Cams Micro DVR":

Not exactly 640x480 as claimed, is it?
Well, being that it must be viewed in a proprietary web-player, I'm not sure I can comment. It is possible the original WMV file was higher resolution.

Well, I'm noting the graphics on the trunk are pixelated, which is consistent with the type of aliasing seen on the Aiptek.

Correct me if I'm wrong but every time I've seen compression mess with fine details, it will blur them not cause this kind of pixelation. It's taking a smooth line and creating false sharp details to it which was pretty close to the problem with the Aiptek hardware.

Most of this stuff is pretty low quality. I know some quality items, but they are very expensive, however a very good item aimed at less than $2000, but has the possibility of being less than $1000 is:

http://www.cineform.com/products/CineFormRecorder.htm

Don't know what happened to these, they are taking a their time and it went pretty quiet.

This is hitting far above what you are looking at in quality, built the price companies are charging for half decent SD stuff is staggering. Component versions is eventually come (presumably with SD resolution and composite). Just a matter of finding a compatible camera. You won't be getting much better. I was looking at putting together a unit myself, fit in the small of your hand, either record uncompressed on multiple SD cards, or wavelet using an analogue devices chip that is used in wireless HDMI.

There are others out there, and maybe some will be cheaper. Black magic design does a PC based recording product, but maybe they eventually will be doing something portable. Professional video equipment sites might have leads on solid state SD resolution recorders cheaper.

The problem you face, is pirates, and the industry is making everybody else suffer so pirates can't make good quality copies (well that is one excuse, it just happens to also force you to buy expensive cameras and subsidise profits of big companies, something that pirates ironically can also easily afford to do). So, less resolution, less quality, higher bit-rates, that does not suite action bullet cams).

I hoped that ambarella would get cheap solutions out for bullet and web cams by now (a combined web and bullet cam with memory card slot could be good) with high bit rate. I think they are working towards bullets cams, but can't remember.

Looks like they are delayed for a while, but posts in this thread mention other recorders:

http://www.dvinfo.net/conf/cineform-...pt-posted.html

A thought, some DV cameras record AV in, not ideal, and I think firewire hard drive recorders might re=quire special setup for video. There was one company talking of a cheap recorder (under $300). But there are a number of small Flash based SD cameras out here. Also there is a cheap firewire miniature camera (around $100).

http://www.unibrain.com/home/

The model number will probably be on this list:

http://damien.douxchamps.net/ieee1394/cameras/index.php

Makes me wonder if a firewire caddy can be induced to record from this.

If anybody is more adventurous, there is a digital cinema project based on the elphel 353 cameras (more security camera sized than bullet) over at dvinfo, that will have a flash memory card rig for recording. If anybody would like to convert into sports bullet cam, Elphel is open to advancement of their product.

HDD DVR are not ideal for worn application, which is what I'm looking for. They require a lot of power, are relatively large and heavy, are sensitive to shock damage, and it would really suck if the power cable pulled out while running.

Plus, well, it seems that HDD DVR can be subject to the same problem, a low quality recording format. Virtually ALL DVRs of any type claim "640x480 30fps DVD quality" but it's a load of crap.
