Hi all, I'm going to be making a large streaming video (about 670 x 350) and am worried about filesize. However, the video is just going to be a guy walking around on a white background - so in effect there wont be much data in the video - it will mostly be white.

My question is, how much does this reduce the filesize by? I know that having a video which is mostly white will have a smaller file size than one which has a busy, high motion background - but will this have a large or small effect?

Any help would be great on this...
