# Reversing Field Dominance

When working in a project that uses clips originating from different interlaced video formats, you may have to reverse the field dominance of clips that do not correspond with the project's interlacing properties.

You can reverse the dominance of clips on the EditDesk using the Dominance command in the A/V Tools menu. When you do so, the first and last fields of the clip are dropped to account for the offsetting required to reverse the field dominance: the result clip is one frame shorter. It is a good idea to capture enough head and tail frames so that the fields dropped on both ends do not affect the frames you want to use.

Both the media and the scan mode metadata tag are changed by this process.

To reverse the dominance of clips:

1. Display the Video menu and then enable Dominance.
2. From the Scan Mode Tools box, select Rev Dominance.
3. Select the clip to which you want to apply the process.
4. Select the destination reel.

   The field dominance of the clip is reversed.
