NOTES:

• All content is 30 fps.

• Readings are taken from an actor machine.

• VFC-compatible machines run with pass-through style cards (HDMI or DP).

• 60Hz project.

• Genlock on all machines which support it.

• One unique video file per layer, all mapped onto one screen.

• Absolute maximum level of performance.

• One more layer means the system starts to drop frames.

• Measured against 16.0.4, build 60742.

Capture Latency

The following table provides data on how many frames of latency the vx 4 requires from capture to output.

60Hz	4-5	4	3
50Hz	4-5	4	3
30Hz	4-5	4	3
