Is it better to export an iMovie with an aspect ratio of "standard" or "widescreen?"
• on how material was recorded - SD-video (4x3) or HD-Wide-material (16x9) ?
• on how it's to be playbacked - Projector capability, Flat-screen TV or old CRT-TV
I would try to get as much info from the picture over to the viewer
e.g. interlaced SD-Video (4x3)
• Use iMovie HD6 or FinalCut any version
• Make a 4x3 project
• if DVD - make it 4x3 too
If I know that there is a full HD 16x9 projector / flat-screen that will show it
• Use iMovie'09 to 11
• Save it as Optimized Full HD on an USB-memory - and in max quality .H264 codec (e.g. to be played via a PlayStation3 and onto a Full Quality HD screen)
