Thank you for the quick response!
Yes. The files were encoded to ProRes 422 LT. I also tried 422 HQ, through both FCP itself and PavTube converter.
I have tried both compressing all frames and self contained movie.
I have noticed on playback, when monitoring framerate in QT, that it seems to vary and not hold true to the assigned framerate. I don’t know if that’s just the way QT is or some other issue. Again, the movie when opened within FCP, plays fine without stutter.
Thank you again.
