Hi all,
Thank you for all your tips. What I did was to export 29.97fps movies to 24.97fps, then I used Cinema Tools to conform it to 25fps. I followed the tips above by using the FCP’s compressor and exported it as 25fps. My piece is about 3 minutes so the difference turned out to be just 4 frames after all.
In any case it’s great to have discovered this issue which I had no knowledge of before. Thanks all!
