Hi all,

I have a 50-minute movie that's been exported from iMovie with the setting "for iDVD" (apparently 720 x 576 DV-PAL format -- I'm from Germany). To make it smaller, I tried to export it from QuickTime Pro as Motion JPEG B. When I exported it at the original dimensions, it showed very ugly interlace jaggies. (That's what already happened when burning a DVD from iDVD.) Also, it seemed to me that the actual pixel data stored in the movie was just 360 x 288 pixels and was interpolated at "run-time", so I chose to export the movie again at that smaller size. (Is my assumption correct, or does QuickTime Player simply not display the full information?)

The main problem I'm having now is that QuickTime doesn't simply take the original frames and compresses/encodes them, but it seems to run out of sync and interpolates between consecutive frames. This makes many frames very blurry, sort of "double-exposed". I tried to convert other movies (movie trailers, for example), but they don't show this phenomenon.

I do not have access to the original camera and movie data, so I need to know if I there is a chance of changing some parameters or something else that I can do to retain the exact frames after the conversion.

Thanks for any help!

I guess I figured it out myself. I exported the .mov with QT Pro to a DV Stream, which I could import into iMovie. iMovie doesn't have the "frame blurring" problem I mentioned earlier. So, the problem must be in the QT Player, because it apparently can't interpret some sort of time code information that iMovie put into the movie in the first place.

Also, I realized that the DV-PAL material does have the full information according to its resolution (720 x 576) -- I found the setting "Video Track: High Quality/Single Field" in QT Player.
