Using Synchronization Points to Create Merged Clips

Before actually merging clips, you need to find a synchronization point between them. There are different ways of doing this, depending on how you shot your footage:

If you have a complicated combination of syncing In and Out points, and your video and audio clips don’t have matching, synchronized timecode, you can add auxiliary timecode to each clip so that the clips’ sync points all fall on the same timecode number. You can then use the auxiliary timecode track (Aux TC 1 or 2) to merge your clips. This is just like using the main timecode track for syncing, but auxiliary timecode tracks are useful because you keep the original timecode track intact, which is critical for recapturing your media from the original source tapes. For more information about adding auxiliary timecode to a clip and its media file, see Modifying Timecode in Media Files.

To synchronize video and audio clips using In or Out points
  1. Open the video clip you want to synchronize in the Viewer.

  2. Scrub through the beginning or end of the clip and find the frame where the clapper on top of the slate first closes.

  3. Set an In point if the “clap” appears at the beginning of your clip, or an Out point if at the end.

    Note: If you decide to use an In point, you should use an In point for each clip you want to include in the merged clip. If you don’t set an In point yourself, the first frame (Media Start) of the clip is used instead. If you decide to synchronize by Out points, you should use an Out point for each clip to be merged. If you don’t set an Out point yourself, the last frame of the clip is used.

  4. Open each audio clip you want to merge in the Viewer, and repeat steps 1 through 3, identifying instead the frame of audio where you first hear the clap.

Once all your clips are synchronized, you can merge them.

To create a merged clip from two or more clips in the Browser
  1. In the Browser, select all the synchronized clips you want to merge.

    Figure. Browser window showing synchronized clips selected and ready for merging.
  2. Choose Modify > Merge Clips.

  3. In the New Merged Clip dialog that appears, select a method with which to synchronize the clips: In points, Out points, Timecode, Aux Timecode 1, or Aux Timecode 2.

  4. Click OK.

A new merged clip appears in the Browser. Merged clips are named after the video clip. Merged clips with no video are named after the topmost selected audio clip in the Browser. In both cases, the word “Merged” is added at the end.
