I am comparing the Canon 780IS and the Sony DSC W290. Both have 1280x720 video. The Canon video size is about 3MB/s and the Sony is 1MB/s. (Canon gives you no choice for quality settings at 1280x720, Sony has normal and fine but the canon is still larger even compared to the Sony "fine" video. ) Plus, I think the Sony is actually better video, at least onmy computer.

The canon uses the H264 codec and the sony uses MPEG4 which I believe are the same thing. What explains the difference in video file size? Will there be a difference in playback on an HDTV from the camera? Can HDTVs render the MPEG4 video or will it be inferior quality because of the compression and smaller file size?

Thank you.
