5.16.3 Mix Controls
All edits are based upon an existing mix, known as the Active Mix. De-
pending 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.
Every edit is based upon the selected Active Mix, the channels/objects se-
lected within the mix, the portion of the mix to be altered, and the type of
edit applied. 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.
