QuoteI had looked at that unit but if you read the specs carefully you notice some descrepencies. First off mpeg2 in itself does not provide DVD quality.  In order to obtain the 20 min of DVD quality mpeg2 stream they claim from 512 MB internal storage would require a 3.5 Mbps bitrate. The resolution they are using is 320X240, often refered to as 1/4 DVD, any higher and the artifacting would drive you insane. There would be no point in attatching a 480 or 520 line camera to such a device. While this device does have the capability to encode mpeg2 the lower resolution and higher price steered me to the samsung, which btw comes with a, albeit poor, bullit cam.

Again I agree that this is a personal solution, not something that would be viable in the professional arena.

well, some sites do not have the correct data, the svav100 spec you speak of is wrong;

Let me provide some real data from our experience with these devices. With over 300 hours onboard footage under our belts, we have used these cameras exclusively for the last 2.5 years and we have NEVER used the resolution you discussed...I do not even know if the setting exists for MPEG2....MPEG4 perhaps, which the camera also supports, most likely using the lesser resolution as a compression technique....

In fact, the SV-AV100 MPEG-2 compression performs either at 352 x 480-pixels at 30 frames per second (normal) or 704 x 480-pixels at 30 frames per second (fine). The captured bitrates are 3Mbps & 6 Mbps respectively.....very close to true DVD quality and to the average joe....pretty darn good quality....

So this is the reason why we use high resolution input devices 480 or 520....better overall video, hands down....

Hawk, let us spare the forum participants, no more geek_speak, we agree in premise....just some points of clarification for you and the viewers (asleep) ;-)
