Audio - Video out of sync

[Zenoberr]

Hello..I'd like to know if I can sync a lengthier audio file over less lengthier video file. My problem is I have a video file (MKV) with duration 1:28:45 hrs and the corresponding audio with 1:32:27 hrs.So this is the case mentioned in the previous post.Also, the video bitrate is 601 kbps and audio (MP3) bitrate is 256kbps.So can I mux them and have the output with least error in sync?Please help.Awaiting response..

Might be because the video is PAL sourced at 25 frames per second, while the audio is NTSC sourced, 23.976 fps. You can use an audio editor to shorten the audio to the new length. Save it as a new mp3 and mux with your video. Another method may be AVIDemux, which has an audio filter that does the adjustment for you (film > PAL).
