I've shot and edited an HD video in FCP 7. The frame size in the video browser says that it's 1280 x 720, 29.97 fps, Apple ProRes 422. When I use the share command to create an "Apple TV" video I have an m4v file created. Playing that file in QuickTime Pro player (7.6.9) it plays in all of its wide-screen glory. However, when I get information about the file in QT, the format says "H.264, 960 x 720 (1280 x 720), Millions AAC, Stereo (L R), 44.100 kHz" and "FPS 29.97." What I don't understand is why it gives both 960 x 720, which is 4 x 3, and then 1280 x 720 in parenthesis. Today I downloaded an evaluation copy of Video Converter for Mac and used this video to test it doing a conversion from m4v to wmv. The program did the conversion, but it plays as 4 x 3. In fact, even simply viewing it in Video Converter (before any conversion) the software displays it this way (4x3). QT displays it correctly. Can anyone provide some answers? Thank you.
