Audio-Video synchronization error in Quicktime .mov file

Discussion in 'Computer Support' started by =?gb2312?B?0c/N+w==?=, Oct 17, 2007.

  1. I have recorded .mov file form rtsp://202.38.70.248/2003sjh/20030901.mov
    using Mov Recorder 1.3. The audio is ahead of video in the recorded
    file. The amount of advanced time is negligible at the beginning of
    the file, but increases gradually as we go forward, and reaches the
    maximum at the tail of the file. I also observe the fps (Frames Per
    Second) of the file by Quicktime 7.2. When playing the rtsp stream
    directly on the Internet, the fps is 25.00. While the fps becomes 24
    in the recorded file. Moreover, compared to the rtsp stream, the last
    part of the video in the recorded file is lost, while the audio is
    complete. I guess the change of the fps is the causation.
    Is there any possible solution to this? Maybe modifying the fps of the
    recorded file is one, but I don't know how to. Thank you.
