Variable time shift

[tbee]

I've searched google and the forums for an answer, but all I found was how to solve a constant time shift. So I decided to post my question anyhow: I have a variable time shift; at the beginning of the movie it is about 500ms and at the end 0ms. Is there a way to correct this? (I.o.w. make the time shift a function of the play time?)

Stretch or shrink the audio by 500 ms (depending on which way the shift is currently) then change the shift to 0. VirtualDub has the ability. Or you can export to Audacity (or any of several other audio editors) and do the adjustments there then import back into any video editor.
