Frame Error - Dropped Frames
Video appears to have missing sequential frames, which results in jerky motion upon playback.
This issue could be caused by a poor framerate conversion where frames have been created or decimated to achieve a desired framerate. Other times data corruption present within the file has forced the decoder to simply ignore the affected sections, leading to potentially significant jumps in the video and audio.
Review your master file. If the issue is present then the only solution is to seek an alternate source.
If your master file looks ok, attempt to re-transcode, ensuring that no framerate conversion is being performed.
Occasionally such an effect could be used intentionally by the creator on a section, or sections, of the content. If you believe this is the case, verify this with the Content Partner, and then communicate those findings to your Netflix representative via Backlot.
