VCD music replaced by mp3, out of synchronous

[karhooi]

hi, I have a VCD MTV karaoke music. To get a better music quality, as in karaoke music, one channel is only music and another one is music+voice.
So i plan to replace the music with mp3. I know I can multiplex and demultiplex using Tmpegenc. But I know the video will out of synchronous with MP3, the question is how can i adjust the music to synchronise with the video with a simple tools???

I'm just curious as to WHY you want to do this...

VCDs don't support MP3 as a compression format for the audio, only MP2...

If the audio length isn't even the same length as the video, you are going to have a very difficult time syncing it... I would say that it probably isn't worth it (unless you are look at this as a learning exercise only).

Regards.
