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 Desktop using the Dominance command in the Format 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.
