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.
