NOTES

  • Content is played back at 30 fps and 60 fps as outlined in the video codec above.
  • All Full HD codecs listed above have an output resolution relevant to 1920 x 1080 pixels.
  • All 4K DCI codecs listed above have an output resolution relevant to 4096 x 2160 pixels.
  • The test media server is run as an actor with its GUI disabled. The Director media server running in the session should be a Dedicated Director with no outputs assigned
  • Full overview on the video playback performance methodology used to capture the above data can be seen here.
