Yep... the video processor in our HD Key Cam has an integral H.264 video encoder pipeline in it, so it controls the camera output bit rate.
That new HD camera dubbed #12 by chuck Lohr encodes with MJPEG video codec, and has a bit rate (and presumably files sizes) about double that of our HD Key Cam. That's probably what is causing the high dropped frame rate as well if the processor used in that camera cannot keep up with the encoding task @ 30 fps (just like the old 808!)
