Variables

		Name	Description
	bool	bGenerateSubFrame
	bool	bKeepAtLeastOneFrame	When cleaning the buffer keep at least one frame, even if the frame doesn't matches the other options.
	bool	bUseTimecodeSmoothLatest	When evaluating with timecode, align source timecode using a continuous clock offset to do a smooth latest This means that even if engine Timecode and source Timecode are not aligned, the offset between both clocks will be tracked to keep them aligned.
	bool	bValidEngineTimeEnabled	Enabled the ValidEngineTime setting.
	bool	bValidTimecodeFrameEnabled	If the frame timecode is older than ValidTimecodeFrame, remove it from the buffer list (in TimecodeFrameRate).
	FFrameRate	DetectedFrameRate	FrameRate taken from one of the subjects. It's expected that all subjects have the same FrameRate
	double	EngineTimeClockOffset	Continuously updated clock offset estimator between source clock and engine clock (in seconds)
	float	EngineTimeOffset	When evaluating with time: how far back from current time should we read the buffer (in seconds)
	int32	LatestOffset	When evaluating with latest: how far back from latest frame should we read the buffer
	int32	MaxNumberOfFrameToBuffered	Maximum number of frame to keep in memory.
	FFrameRate	SourceTimecodeFrameRate	What is the source frame rate.
	double	TimecodeClockOffset	Continuously updated clock offset estimator between source timecode clock and engine timecode provider clock (in seconds)
	float	TimecodeFrameOffset	When evaluating with timecode: how far back from current timecode should we read the buffer (in TimecodeFrameRate).
	float	ValidEngineTime	If the frame is older than ValidTime, remove it from the buffer list (in seconds).
	int32	ValidTimecodeFrame	If the frame timecode is older than ValidTimecodeFrame, remove it from the buffer list (in TimecodeFrameRate).

Deprecated Variables

		Name	Description
	FFrameRate	TimecodeFrameRate_DEPRECATED	DEPRECATED: TimecodeFrameRate is now read from each individual subject from FQualifiedFrameTime.
