Section 10 – Operations related to timecode

1)Use the LEFT and RIGHT keys to choose the field to change (hours, minutes, seconds or frames) and then use the UP and DOWN keys to change the value of that field.

You can also enter a time offset directly using the function keys (see 5.2.2, “Using the function keys as number keys”).

The time you enter will then be the time at which the timecode starts from the beginning of the tape. For instance, if you enter an offset of 00:59:00:00, and the tape is positioned exactly 1 minute after the start, the timecode will be 01:00:00:00.

10.2.4ABS-13 and ABS-23 settings

These settings are useful if you are recording many pieces on one tape. They automate the pro- cess of providing a timecode “pre-roll” and start- ing each piece at an easily-memorable timecode position.

The ABS-13 setting should be used to record pieces of 10 minutes r less in length, and the ABS-23 for pieces of 20 minutes or less.

00:57:0OffseTapeTCMot30NDMod0:00ABSde -e13

With both of hese settings, the start of the tape is automatically set with an offset f hh:57:00:00, where hh is the number of hours.

1)Use the LEFT and RIGHT keys to select the “hours” field.

2)Use the UP and DOWN keys to set the “hours” value.

Here we assume (for simplicity) that the “hours” value has been set to 00. If you set this to a differ- ent value, add the appropriate offset as you read this explanation.

Timecode is synthesized, starting at 00:57:00:00, allowing three minutes of timecode “pre-roll” before the nominal start of the piece at 01:00:00:00.

With ABS-13selected, once the tape is posi- tioned approximately 13 minutes from the start,

the23timecode will restart at 01:57:00:00. If ABS- has been selected, this will occur approxi- mately 23 minutes after the start of the tape (the

piece is 20 minutes long). This allows another track to begin at 02:00:00:00.

This process continues until the end of the tape is reached. Wherever the tape is located, this calcu- lation will be performed, allowing you to locate each track easily with reference to the timecode values.

The diagram below shows the relationship between the “synthesized” timecode and the abso- lute time on tape, assumiong that the “hours” value has been set to 00.

The TAPE TC indicator by the tape counter will

light when timecode reco ded on tape or synthe- sized from ABS is being re d. The indicator will not light in areas of the tape where no timecode

has been recorded ifhas been

selected, and will not light at the beginning or end of tape if any of the ABS modes has been select- erd. Timecode is not read in STOP mode and the indicator will not light in STOP mode.

As w ll as the tape counter, the display screen can also be used to show tape timecode values and the fr me r te currently recorded on tape, as described below.
