Setting an audio source In point between timebase divisions

You can set the source In point of an audio clip to either the individual frames or the audio samples in a clip. For example, when editing a motion picture for film, you might want an audio clip of a finger snap to start playing the instant that sound is heard, but you may find that the motion-picture time display of 24 frames per second (initially set to match the timebase) is too coarse to start playing the audio when you want. You can use the Frames/Samples time display option to set a source audio In point more precisely than one timebase unit, although the project timebase still determines where the source Out point can appear in the Timeline.

To set a source In point between timebase divisions:

1 Open the clip in the Source view or in a Clip window.

2 Choose Window > Window Options > Monitor Window Options or Window > Window Options > Clip Window Options, depending on the window in which you opened the clip.

3 For Count, select Frames/Samples, and click OK. Now the playback controls will operate among individual frames or samples instead of using the project timebase.

4 Mark the In and Out points for the clip. See Marking and finding In and Out points.

5 If you want to set the count back to the previous setting, choose Window > Window Options > Monitor Window Options or Window > Window Options > Clip Window Options, select the original time display from the Count menu, and click OK.
