5.16.3 mix Controls
All edits are based upon an existing mix, known as the Active Mix. Depending
on the type of edit selected, data may be needed from another mix or snapshot.
The controls for the necessary mixes appear in the combo boxes to the right
of the Object Picker or Mix Viewer window.
5.16.3.1 Active mix
The Active Mix provides the primary data set that is used during editing. Ev-
ery edit is based upon the selected Active Mix, the channels/objects selected
within the mix, the portion of the mix to be altered, and the type of edit ap-
plied. In other words, the data (parameter values) from the selected Active
Mix objects is altered according to the chosen Edit Type and Edit Region
when the edit is performed. Previously existing and altered data are combined
and saved as a new mix.
Most Edit Types (Set, Trim, Freeze, and Clear) need data from only the Active
Mix for an edit to be performed. Spread, Merge, and Update Snap edits all
require data from other mixes. When an additional data source is needed to
perform an edit, an additional mix combo box (containing the appropriate
controls) will appear when the corresponding Edit Type is chosen.
Each mix needed for an edit has a combo box that contains the necessary
controls for that mix and edit type.
The Active Mix combo box has a primary control set:
• Timecode Entry Fields , used to select the Edit Region.
Timeco­de Entry Fields For most edit types to be performed, an Edit Region must be established within
the Active Mix using timecode addresses (Update Snap does not use an Edit
Region). The Edit Region can be as short as a single frame or as long as an
entire mix.
Edit Regions are defined using Timecode Entry Fields. The Active Mix
includes three Timecode Entry Fields:
In Time Starting point for the edit; the timecode address from which data is altered;
Out Time Ending point for the edit; the timecode address from which data is no longer
altered;
Length Duration of the edit; the total time of the Edit Region;
Length Lock Freezes the value of the Length field.
