First time using this forum, so I hope I'm doing this right. I have iMovie 08 and make videos to post on some video sharing sites. My problem is I changed my settings once and now all my videos look terrible and I can't for the life of me remember what the default settings were. After making a video, I click 'share', 'export to quick time movie' and then my problems start. My file is over 100MB and most sites don't allow this. How do I compress and not lose quality and/or what are the default settings that were on the Mac when I got it a few months ago? Thanks for any advice and help and let me know if this is in the wrong forum.
