Open and Closed GOP files

A GOP (Group of Pictures) structure and size determines the I-, P-, and B-frames that will be used during transcoding.  While open GOPs provide slightly better compression than closed GOPs of the same size and structure, there are limitations to processing open GOP files in the cloud.

Pixvana supports closed GOP files for optimal cloud transcoding.  Here are some alternatives to uploading an open GOP file:

  • Upload your file in the ProRes format or as an image sequence
  • Adobe Media Encoder provides export settings to create closed GOP MPEG-2 files
