This question is for all of you that have a website and hosts movies on there. What is a good compression size for webistes? ha.

It depends on if you want to make it easy for dial-up users or not. If you do, you will be sacrificing alot fo quality. For dail-up, 300x200, with 8bit sound. For broadband, you can go up to 600x400, but would unless you have details that need to be seen, like in mine, then 420x280 would be a good size.

Keep in mind, that is not just the resolution, but also the audio rate and video compression that makes all the diference. You will probably want to export in Media9 format, Divx format, or compressed quicktime format.

I do 320x240 (<100kps) for DSL/Cable - thats essentially what apple.com/trailers does, it loads and plays instantly on DSL.

ALWAYS use QuickTime or MPEG. Quicktime works perfectly on both platforms and has great quality and filesize. MPEG is a good second choice, because hardly anyone on the face of the earth would have a problem playing it, but it dosn't look quite as good.

Check out the trailers in my sig link - I can give you the exact specs if you want them.
