Output Controls

The VTR Output Controls are shown below.




The Actions buttons in the centre perform the specified output operation e.g. Output List, Stop Output etc.

Status Fields


VTR Deck status is shown in the VTR row.


If the tape is record inhibited, it will show REC Lock.


During processing or output, this row will show the list status and output progress.


The Buffer row will display how many frames are buffered and ready for output.

Output Channels

Use the tick boxes to choose which data streams to output - video, audio or both.

Record Edit Mode



This drop-down list allows you to select the edit mode, which determines how material is written to tape. The following modes are available.


Insert Edit

Each event is recorded at the record in-point timecode.

This mode requires a tape pre-striped with the right record timecodes.

Assemble Edit

This locates the record in-point timecode of the first event and starts recording. From here, timecodes are generated (assembled) as the output proceeds. Only the initial in-point timecode is required (hence only a partially striped tape is necessary).

Crash Record

This method starts recording at the current tape position, with no pre-roll or post-roll used, and writes out timecodes as it records. This mode will therefore work on a blank tape (no pre-striping required) and is only suitable for laying off contiguous material.


The Pad Events option is available here.

Preview BVB

This mode previews the output. It does not write anything to tape.

The preview shows : Black - Output Video - Black.

Preview VVV

This mode previews the output. It does not write anything to tape.

The preview shows : Video - Output Video - Video.


This mode reviews the output on tape. It does not write anything to the tape.



Pre-striped tapes must be striped at the same frame rate as your composition.


The Actions buttons will change depending on record mode selected.


Timecode Output Order



This drop-down list allows you to select which timecode order is to be used when writing the events to the tape:


Source Order TC (C)

Record each event to tape at its original location (i.e. its source timecode), ignoring its location on the composition timeline (record timecode).

Event handles : enabled.

Source Order Tape (C)

This is the same as Source Order TC except the list is sorted by tape first, then source timecode.

Event handles : enabled.

Record Order (A)

Record each event to tape at its composition (record) timecode location i.e. the same sequential order as your composition timeline and at the same timecodes (unless "Use mark as in point" is set, see below).

Event handles : disabled.


Event Handles are enabled for Source Order mode layoffs :





Note that Source Order layoffs will not render transition effects.



When Source Order is selected, the Mark-In/Out values in the Event List will change to show the source timecodes matching the start and end timecodes of the list events. When Record Order is selected the record timecodes are shown instead.

Pad Events In / Out



Crash Record only.


Pad Events controls whether padding is to be applied during output. Padding  consists of black frames with contiguous timecode being written before and after the events being laid off.


How much padding is written is controlled by the In and Out timecode fields.



The timecode given to the padding will always precede the timecode of the 1st event being laid off, and if a Mark-In Timecode has been supplied the timecode of the padding will precede the Mark-In TC.


Padding can only be carried out in Crash Record mode.

In / Out Markers



The In, Out and Duration boxes relate to the in, out and duration times of your event list. Record timecodes or source timecodes are used according to the Timecode Output Order selected.


You can set the In point timecode by :


Pressing the Set In button (Cue In). This sets the In timecode to the current deck position.
Erasing and typing in a new timecode via your keyboard.

Use mark as in point

Ticking this box will set your layoff in-point to the In timecode set. Your list will be recorded starting at this In timecode

Output List

This button is enabled when there are events in the event list. Pressing it will start off the layoff to tape of all the events in the list.



Unlike the VTR Capture module, you cannot select a group of events for layoff from the event list. All items in the list will be output. To select a sub-section for layoff, see Laying Off Sections.

Output Single

This button is enabled whenever a single event is selected/highlighted in the event list. Pressing it will layoff that specific event only.

Stop Output

This button is only enabled when there a layoff is in progress. Pressing it will halt the layoff.
