This file shows a sync error in playback. It's using WMV3 and WMAV2. If i open it in QuickTime, and export (using Flip4Mac) a smaller portion of the file, it appears to stay in sync. The only thing different between the two files is the order of the streams, and that the exported version from QT has a higher bitrate. This version: Duration: 00:28:30.6, start: 3.064000, bitrate: 322 kb/s Stream #0.0: Video: wmv3, yuv420p, 448x336, 30.00 fps(r) Stream #0.1: Audio: wmav2, 44100 Hz, stereo, 31 kb/s (This was before reducing the size) This file plays correctly, which was the above file, clipped and reexported: Duration: 00:00:29.9, start: 5.000000, bitrate: 698 kb/s Stream #0.0: Audio: wmav2, 44100 Hz, stereo, 64 kb/s Stream #0.1: Video: wmv3, yuv420p, 448x336, 30.00 fps(r) Any help would be appreciated!
