Speedup Video, "stretch" audio?

post #1 of 2
Thread Starter 
Hello guys.

So I have a problem. I have a movie.

The thing is, the audio is very choppy, and I've figured out why.
Upon Dissecting the 2:04:31 movie (With MKVmerge), I was given an audio file that is only 1:59:25. So I believe that vlc and the mkv format are attempting to stretch the audio, though this causes breaks in the audio of the movie and makes it lose all sound for a half a second or a second everyone 5-10 seconds.

I tried to "stretch" the audio using Audacity, a free audio editting tool, but to no avail. (The voices didn't sync with the movie)

I was thinking of speeding the video track and playing the audio track separately, but I'd need a player that could speed it up by a very exact amount, around 4.22% to make it flesh

I'm at a loss of what to do. Is there any way I can make the audio track fit perfectly with the video track? If so, what tools (preferably free) would I need to use, or what do I need to do?

Thanks for the help in advance.

Thanks for the help guys, I got it xD
(lol )

Just for future reference and help if anyone needs it, using MKVmerge I changed the timecodes (framerate) of the video from 23.97 to 25, which was actually exactly what I needed to do. The audio and video fit perfectly together now, which I believe hints that my video was PAL when it needed to be something else (might be talking outta my ass)

So changing the framerate of the video and the subtitles made the video work perfectly. It is now 1 hour, 59 minutes, 25 seconds long.
