Field dominance

From Wikipedia, the free encyclopedia

In video engineering, field dominance refers to the choice of which type of field of an interlaced video signal is chosen as the point at which video edits occur. There can be only two possible choices for field dominance in normal interlaced video, as there are only two types of field to choose from.

Re-editing old video material already edited with a different field dominance conventions can be problematic, as it can lead to "flash fields" when old and new edits are made too close together.
