I am running into a problem with inconsistent syncing. I think it has to do with needing to use "Forced Film".

The problem is that I am getting 1/2 synced movies where in the middle of the movie the goes out of sync. I think it is because of the NTSC change frame rate problem.

From what I understand, forced film takes care of this problem. I don't see a forced film option on ffMpeg but I do se DeInterlace which I think is the same thing.

What can I do to solve this problem ?
