PTPToLTCTimecodeFrameOffset

Frame offset subtracted to converted timecode to match LTC timecode due to transportation of timecode For LTC, it takes a full frame to transport the new value but for PTP, this doesn't happen, time is local.

Syntax

UPROPERTY (EditAnywhere, AdvancedDisplay, Category="Genlock options")  
int32 PTPToLTCTimecodeFrameOffset

Remarks

Frame offset subtracted to converted timecode to match LTC timecode due to transportation of timecode For LTC, it takes a full frame to transport the new value but for PTP, this doesn't happen, time is local. If a timecoded video feed is coming into Unreal, if PTP timecode isn't offset, it will be leading by 1 frame. A value of 1 means PTP timecode is 1 frame ahead so we substract 1 frame to the result A value of -1 would mean PTP is late by one frame compared to LTC so we add a frame to the result.
