Limiting How Much Media Is Copied or Deleted

When you select clips to process with the Media Manager, keep in mind that those items may be affiliated with other clips in your project. Specifically, a master clip, which refers to a media file on your scratch disk, may have many affiliate clips located in different sequences. When you process your media files in the Media Manager, some options allow you to choose how much media is processed: only the portion referred to by a single affiliated clip, or the portion of media referred to by the selected clip, its master clip, and all other affiliated clips.

Consider the following scenario: there is a 10-minute media file called “Crowd Shot” on your hard disk. A master clip in the Browser refers to the entire length of the Crowd Shot media file, and In and Out points are set somewhere in the middle of the clip. Throughout the course of editing, you drag the Crowd Shot master clip to two different sequences (Sequence A and Sequence B) and use different portions of the media file in each case. This creates two clips affiliated with the master, one in each sequence. Since each affiliate clip has different In and Out points, each one refers to a different portion of the same media file:

Preserving Media Only for the Selected Item

You can use the Media Manager to create a copy of Sequence A along with only enough media to re-create Sequence A (and thus ignoring any other sequences or master clips that might reference the same media file).

To preserve media only for a selected item
  1. Select Sequence A in the Browser, then choose File > Media Manager.

  2. Choose Copy from the Media pop-up menu.

  3. Select “Duplicate selected items and place into new project.”

  4. Select “Delete unused media from selected items.”

  5. Deselect “Include master clips outside the selection.” This option ignores additional media referred to by the master clip.

    The resulting media file contains only the first ten seconds of the original media file, which is sufficient for re-creating Sequence A, but not for re-creating the original master clip or the clip in Sequence B.

Preserving Media for the Selected Item and Its Master Clip

You can create a copy of sequence A along with enough media for the clip in Sequence A and enough media to preserve the media In and Out points marked in the master clip.

To preserve media for the selected item and its master clip
  1. Select Sequence A in the Browser, then choose File > Media Manager.

  2. Choose Copy from the Media pop-up menu.

  3. Select “Duplicate selected items and place into new project.”

  4. Select “Delete unused media from selected items.”

  5. Select “Include master clips outside the selection.” This option preserves the media referred to by the master clip’s In and Out points, so the master clip is preserved as well as the clip in Sequence A.

Preserving Media for Selected Items, Master Clips, and Affiliated Clips

You can create a copy of Sequence A along with enough media for the clip in Sequence A, Sequence B, and the media referred to by the master clip’s In and Out points.

To preserve media for the selected item, its master clip, and all affiliated clips
  1. Select Sequence A in the Browser, then choose File > Media Manager.

  2. Choose Copy from the Media pop-up menu.

  3. Select “Duplicate selected items and place into new project.”

  4. Select “Delete unused media from selected items.”

  5. Select “Include master clips outside the selection.” This option preserves the media referred to by the master clip’s In and Out points, so the master clip is preserved as well as the clip in Sequence A.

  6. Select “Include affiliate clips outside selection.” This option preserves the media referred to by all clips affiliated with the master clip, which means preserving the media referred to by the clip in Sequence B.
