Member Enumeration Documentation

enumETimeMode

Time modes.

Remarks:: ModeeNTSC_DROP_FRAMEis used for broadcasting operations where clock time must be (almost) in sync with timecode. To bring back color NTSC timecode with clock time, this mode drops 2 frames per minute except for every 10 minutes (00, 10, 20, 30, 40, 50). 108 frames are dropped per hour. Over 24 hours the error is 2 frames and 1/4 of a frame.

: ModeeNTSC_FULL_FRAMErepresents a time address and therefore is NOT IN SYNC with clock time. A timecode of 01:00:00:00 equals a clock time of 01:00:03:18.

ModeeFRAMES30_DROPdrops 2 frames every minutes except for every 10 minutes (00, 10, 20, 30, 40, 50). This timecode represents a time address and is therefore NOT IN SYNC with clock time. A timecode of 01:00:03:18 equals a clock time of 01:00:00:00. It is the close counterpart of modeeNTSC_FULL_FRAME. Time modes.

Returns:: Time value.

void SetTime	(	int	pHour,
		int	pMinute,
		int	pSecond,
		int	pFrame=`0`,
		int	pField=`0`,
		int	pTimeMode=`eDEFAULT_MODE`,
		double	pFramerate=`0.0`
	)

Set time in hour/minute/second/frame/field format.

Parameters:

	pHour	The hours value.
	pMinute	The minutes value.
	pSecond	The seconds value.
	pFrame	The frames values.
	pField	The field value.
	pTimeMode	A time mode identifier.
	pFramerate	indicate custom framerate in case of ptimemode = eCUSTOM

Remarks:: Parameters pHour, pMinute, pSecond, pFrame and pField are summed together. For example, it is possible to set the time to 83 seconds in the following ways: SetTime(0,1,23) or SetTime(0,0,83).

void SetTime	(	int	pHour,
		int	pMinute,
		int	pSecond,
		int	pFrame,
