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
