Why is video played in speedgrade uneven and slow? The sound is also choppy. I exported 2 different sequences into speedgrade and got the same result. I imported a cineform hd file into premiere 6. There is no preset sequence that exactly matches that cineform file, but I imported that file then chose the "change the sequence setting to match clip" option. The file played great in Premiere 6. Then I exported that file to Speedgrade. Once in Speedgrade the video played a bit normal but mostly slow and sound was choppy. Why?? The same happened with .mov video from my Canon 5D mark 2.
During the process of 'sending to Speedgrade,' the files are converted to DPX files.
If you don't have enough drive throughput or enough horsepower (GPU cards - nVIDIA) then the playback will be choppy.
