Automation
Mix/Pass Trees
For instance, if a fader is moved continuously then a change in level will be recorded against every frame of
timecode until the fader is released. This can be seen in the Event List as a series of individual events at each
frame.
Safety Snapshot
A Safety Snapshot is take when Play is pressed to start timecode running. It is a Snapshot of the whole console
(i.e. it is not affected by either Automation Scope or Snapshot Scope). Otherwise, it is the same as a standard
Snapshot.
The Safety Snapshot is not affected by and does not affect the automation system. However, it is stored with a
Mix/Pass (when a Record Pass is kept).
A Safety Snapshot is only used when loading a Mix/Pass revision from the Mix/Pass Tree. It can optionally be
loaded or ignored at this point.
One way in which this can be used is to have an empty Mix/Pass Tree that has a Safety Snapshot with favourite
control settings. This could be loaded so that, for instance, the Safety Snapshot is applied before a New
Mix/Pass Tree is created.
Label List
The Label List is a set of grabbed timecodes with short text descriptions (i.e. labels).
These can be used to mark significant points in timecode (e.g. scene changes). The main use of the Label List is
as a source of useful timecodes for functions such as Locate, Cycle, offline editing, etc.
Play Pass
The Play Pass is used to play back control moves.
As timecode runs at play speed, the automation system uses the times stored against the Automation Events to
determine when the control value in each event should be played back.
Record Pass
A new Record Pass is made when changes are made to the Play Pass. When a Record Pass is kept then it
becomes the new Play Pass.
Timecode Considerations for Mix/Passes
The timecode at which an event is recorded is stored in a format that is independent of timecode. However,
each event time that is stored will depend on the current frame rate.
This means that the frame rate is significant for a particular Mix/Pass. For instance, a Mix/Pass that is recorded
at 25 frames per second (fps) should be played back at 25fps.
This does not prevent a Mix/Pass from being played back at a different frame rate. However, AMS Neve advise
against this as it will probably cause frame slippage and may have other unpredictable effects.
Timecode Display
A consequence of the method of storing time values is that the display format can be changed at will (although
this would probably not be done in practice). Timecode can be displayed in standard HH:MM:SS:FF format or
as Foot-Frames, as long as the same frame rate is used.
