![]() The total time of the film is 1h:28m:32s. ![]() Somehow, the better-quality video is playing a little faster so that the audio progressively falls behind and out of sync, and it happens as early as within the first 10 minutes, and gets worse as the video progresses.īy this I mean, by about the 11-minute mark, the audio is clearly behind by about a second, but as the video plays, the audio falls more and more behind til its behind by approximately 3 secs (at around the 50-min point of the movie) and has fallen even further behind by about 7 seconds by the end of the video. So the audio is not the problem (other than volume) - it's the video. I extracted the audio from both videos and found they're of the exact same length, save for a very small difference of less than 100ms. The other MP4 file has higher quality video, no pixelations (at the same point in the movie), however, the audio is screwed - not only is it lower volume (which I can fix easily), it is badly out of sync (this is where I am having troubles). ![]() One is a lower-quality-but-not-bad video, which I could live with, except it exhibits a bad "pixelation" problem at one point (this is not a mere disturbance during playback, it is "encoded" into the file). ![]() I have 2 MP4 video files of the same movie. ![]()
