I have played with the picture quality in QuickTime and iMovie HD. In addition, I have spent over a week Exporting different quality settings (Options button) and uploading to youTube, usually at least two movies a day. I would compare them to previous movies, note the poorer picture quality and then remove them from youTube. Here is what my QuickTime Pro Inspector reports:
All AVI files downloaded from Flip Camera: Format: Generic MPEG-4, 640 x 480, Millions Microsoft ADPCM, Mono, 44.100 kHz
iMovie 3 Export Before QT 7.4.5: DV, 720 x 576 (768 x 576), Millions 16-bit Integer (Little Endian), Mono, 22.050 kHz
The next two Exports do not have the same high-resolution picture quality when uploaded to youTube:
iMovie 3 Export After QT 7.4.5: DV, 720 x 576 (768 x 576), Millions 16-bit Integer (Little Endian), Mono, 22.050 kHz
iMovie 6 Export on 6 May 2008: DV, 720 x 576 (768 x 576), Millions 16-bit Integer (Little Endian), Mono, 22.050 kHz
Here I am making the same movies from the same Flip Camera, but with poorer picture quality ever since QuickTime 7.4.5 downloaded. There is a poor picture quality problem with QT 7.4.5 interfacing with the Flip Video Camera when uploaded to youTube.
In addition, all MOV and AVI Flip Camera files downloaded are ?greyed out? (just now downloaded new Flip AVIs from my two week trip to South Carolina) and will not Import in to iMovie 08. I have tried every Import command possible. However, if I Import theses files in iMovie HD, then Export the new movie to the desktop, the new AVI movie will open in iMovie 08.
I suspect these problems have to do with Apple upgrading the software QuickTime and iMove. As noted from the QT Inspector, Flip?s AVI files are Microsoft coded. Flip Video needs to upgrade their software for downloading AVI and MOV files from the camera for Apple users.
Thanks again for post, I have tried all the suggestions you mentioned again today with some new Flip Videos.
