dynamic controls currently on the work surface to illuminate. This pro-
vides a very quick and easy means of identifying dynamic controls.

5.3.1.3 Mix Snapshot
The Mix Snapshot contains two types of data:
• The values for Static objects.
• The initial values for Dynamic objects from the beginning of the Mix
Pass up to the first recorded change.
Every Mix Pass has a Mix Snapshot. When a Mix Tree is first opened, a
Mix Pass is created that contains a Mix Snapshot with a Static value for
each control. The Static value stored in the Mix Snapshot is the current
value of the control at the time the Mix Tree was first opened. As a mix
progresses the following operations occur:
• Changes to Static values are written directly to the Mix Snapshot each
time a new Mix Pass is created.
• Changes made to Dynamic objects are written to timestamps (timecode
locations) within the Mix Pass.
When changes are made to Static Objects, the Mix Snapshot is automati-
cally updated when the next Mix Pass is generated.
The Mix Snapshot for Dynamic objects may be updated in two ways:
• Using the “Extend Back To Begin” Mix Pass function. The value of the
control at the time of a punch-out will be written back to the beginning
of the Mix Pass (essentially updating the Mix Snapshot).
• Performing a “Update Mix Snap” edit using the OFLA offline mix edi-
tor.
In normal V3.0 operation, use of the Mix Snapshot is mostly transparent to
the user and there is no need for manual updates.
