This probably explains why the 'pros' use some expensive cameras... ;-) http://damien.douxchamps.net/ieee1394/cameras/ Using a decent mount (ie. DIY steady cam ideas) and in-built image stablization in the camera may help. If you are attempting to record onto a PC (rather than just on the camera itself) you could look into DV4Linux (http://dv4l.berlios.de/) and use a firewire capable camcorder. >From what I understand most HD camcorders don't have the firewire port with live video stream, and the video stream is encoded as MPEG4 rather than DV (basically MJPG) so there is more work to extract the image afterwards. For HD maybe you could grab just the I frames (which would be equivilant to MJPG at a lower refresh rate)... Cheers, Mungewell. PS. I did look into using a DSLR over USB, however it seems the limiting factor is that the shutter would wear out pretty quickly. There are some EOSes with a live preview modes (supported by the sensor) but these are at a lowish resolution.
