Mixing Frame Rates and Field Motion Types

The system calculates In and Out points for the source material by using the sync frames and
the existing In and Out points in the sequence for the previously edited clip that you want to
replace.

When you select the tracks you want, check the durations before you perform the edit. If you
replace a clip in an overlap edit and the position indicator falls within the overlap, you might
end up replacing the wrong material unless you select the entire segment you want to replace.
See “Selecting and Deselecting Segments” on page 694.
Enabling Single-Mark Editing
Single-mark editing lets you establish a single mark, and then use the location of the position
indicator to determine the second mark when making the edit. You can use this procedure in
several ways to save steps:
You can mark an In point in the Source monitor and then perform a splice-in, overwrite, or
replace edit without marking an Out point.
You can mark an Out point, locate a frame for the In point, and then perform the edit without
marking the In point.
You can mark the In or Out point, play, step (jog), or shuttle through the clip forward or
backward, and then press the Splice-in, Overwrite, or Replace Edit button to perform the edit
on-the-fly without adding the second mark.
To enable single-mark editing:
1. In the Project window, click the Settings tab.
2. Double-click Composer.
The Composer Settings dialog box opens.
3. In the Edit tab, select Single Mark Editing.
4. Click OK.
Mixing Frame Rates and Field Motion Types
You can work with clips of any frame rate or field motion type (interlaced or progressive) in a
project, regardless of the project’s type. For example, you can work with 30i clips in a 24p
project. In your Avid editing application and in this documentation, clips that do not match the
frame rate or field motion type of the project are known as mixed rate clips.
You can view and play mixed rate clips in the Source monitor or in pop-up monitors. You can
also edit mixed rate clips into a sequence.
