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.

Capture Latency

The following table provides data on how many frames of latency the VX 4N requires from capture to output:

VX 4N SDI

Refresh Rate	Normal mode (frames)	Low Latency mode (frames)	Ultra-Low Latency mode (frames)
60Hz	5	4	3
50Hz	5	4	3
30Hz	5	4	3
