The clip is not out of sync until I render it with MF4.

The original clip does not require fixing since it is in sync. The clip I get after rendering with MF4 (I use the "export" facility with Two Pbutt rendering), is out of sync.

I have tried to run the original clip thru VideoReDo just to make sure it is OK and then render it with MF4 - it then becomes out of sync.

I have also run the rendered clip that is out of sync thru VRD and it does not correct the problem.

I tried that before and could not get it to work in MF4. But this time I spent more effort because you recommended it. If I play with MF4 carefully I can get it to work. By that I mean saying No to the dialog that asks me if I want to "improve" the import. Apparently that's when things get screwed up. So what I did was to subsbreastute the VRD fix for the old one and pretend that it was the same as far as MF4 is concerned.

Now it works. Maybe I need to change my mind about VRD-MF4. But it still seems to be a lot of fooling around just to fix something that should not be screwed up.

BTW, the adjustment was 500 ms, or 1-2 second. That's 15 frames. I wonder if that is significant.

Also the out of sync condition gets progressively worse each time the scene changes from the singer to something else and back. So that 1-2 second was a compromise to get the overall clip as balanced as I could.

I suppose I could split the clip into pieces and apply the right about of sync shift to each segment. But then when I glue them back together I might experience gaps in the audio which is far worse than lip sync problems.

Thanks for the buttistance. You were a lot more helpful than the babies who whined about my criticism.
