How to solve out of sync ?

[Benjy]

I've encoded a .ts file into .mkv format . The original audio was MPEG Audio . After encoding resulted a similar MPEG Audio track but out of sync.
I converted MPA into AC3 but same out of sync between sound and image..

How could I solve this issue ???

What did you convert with?
What kind of audio sync? Progressively worse or constant?
Ts source details? Identify with mediainfo.

You didn't answer the question. Is it off by the same amount all the way through (easy to fix) or does it get worse the longer the video plays (much harder to fix)? My guess is that it's off by the same amount all the way through and you just have to delay the audio by the correct amount when muxing (or get rid of the delay entirely using DelayCut).

[Benjy]

Yes , is it off by the same amount all the way through ....

I'll try DelayCut ,or.... is there another proper method / soft ???

[manono]

There are other programs, yes, that can remove delays. If you know the amount of the delay, though, DelayCut can't be beat (as long as the audio is DVD Compliant, which MP2 audio is). Just figure out the amount of the delay, fill in that amount in the Delay->Start box, Process it, and use the 'fixed' audio when muxing.

[Benjy]

That's the problem (
I don't know the amount of delay and I don't know how to figure it out

[manono]

Oh, play the video using a player that can adjust the delay on the fly. I use MPC-HC and the + and - keys to adjust the delay. The amount you're delaying the audo will show at the bottom briefly. Just remember that 1000 ms = 1 second.

OK ,many , many thanks...let's see !!!!!

I'll be back with ...good results , I hope
