Have you tried using the original QT file in an appropriate sequence? MPEG2 breaks down with a lot of quick motion that may result in the jerky motion you describe. The other thing to try is to convert it to an intra-frame type like P2 that could help you.
Is there any way we can see a sample of the problem?
in the meantime I have uploaded two short sequences of the film that shows two problems. The sequence "jerk" shows the problem of movement in the 3D animation. The sequence "dissolve" shows a radial blur by dissolves in the film.
The received noncompresed original proRes Files from a finalcut pro editing suite are ok.
To convert the file I took a P2 1920x1080i/p project settings. Is that ok? I exported the files as a .m2t Stream 2pass VBR min Bitrate 25 Mbits, Target Bitrate 30 Mbits, maxBitrate 35Mbits. My player is a Broadcast Player Adtec Soloist HD PRO, with max Bitrate playback from about 60 Mbits. So the player is not the problem!
Is it possible to get project and encoding settings, to optimize the smoothness of playback?
Here my links from the files and XML Settings:
The encoding settings are the same in both files
