IF (Open AVI & Edit & Save), many times, loose quali

[billy47]

I Know that saving in any compressed format loose bits and each re saving, the quality goes down. Question: its true for avi files?. What happen if open one AVI file, edit someone, and save it, and i repeat again, and again, many days, and so, many times. My final Avi file , have a poor quality?.

And Then, what avi format is the best for edit many times or cicles?

Thank for help me.

Sorry but my english.

Uncompressed AVI or HUFFyuv codec, those are the two that will have no decrease in quality after multiple edits and resaves. Those 2 codecs take up a large amount of room on your hard drive though.

You could use Virtual Dub to do simple cuts with your compressed AVIs and lose no quality. Down side is you can only do cuts, no effects or so (well you could, but you'd lose quality).

Thanks for your tip about codec HUFFyuv, i will try to findit an test it, I hope that take less amount of HD room that uncompressed AVI.
