1
The User input delay is specified as 0 to 6 full frames. plus one frame in pixels and lines. The Delay Wrap Position on the
Frame Sync web page roughly indicates what fraction of that last frame of adjustable delay is being used. Because the input
video delay with respect to genlock frame position can vary, the Delay Wrap Position with respect to User Input Delay will
vary.
2
Full Frame Mode always has at least 1 frame minus 5 lines of electrical length.
3
Video distortion can occur with User Input Delay that gives ~150 pixels of electrical length. Increase the delay to give a
total of ~300 pixels of delay for the optimum minimum delay setting.
