I'm drawing a blank on what to do with this mpeg file...
I thought I've done this before, but maybe not.
What I have is two mpeg files that are of the superbowl from this year. The source files are replaytv recordings two files at a total of 10GB. I want to reencode the video to a much smaller size and cut out the commercials. I was thinking to run the file with mpeg2dec through avisynth, trim the file and pipe the output to an encoder. I created my trim list and now I can't get any further. I can use dvd2avi to make the two parts into 1, convert mpeg video to d2v for mpeg2dec to use in avisynth. So far so good, the video is fine. The audio source from the replayTV is mpeg-audio, layer II(if it matters). And this is where the problems come in. The audio has a offset of -109ms (I do care about the sync). I don't know of any way in avisynth to apply an offset to the audio, is there one? More importantly, I can't get MPA file for avisynth to work with. I guess I could convert the audio to wav and adjust the offset when it's converted (I think I have to add 109ms of silence to the start). But, this seems like a bit much to do while trying to preserve sync on a 3hr recording. Anyone got any suggestions on what I could do? |
