Setting Field Dominance

Each video frame is made up of two fields of alternating lines. These fields are updated at twice the frame rate of the clip. Field dominance determines which field is generated first and is usually determined by the type of video card you used to digitize footage. Make sure that the field dominance in your workspace is the same as the field dominance of the original source material. If it is not, clips are displayed incorrectly.

To set field dominance:

1. In the Workspace panel, select the Footage operator you want to change.

Note: You can also select the Footage operator in the Footage Library.

2. Click the Footage Controls tab.

The Footage Controls panel appears.

3. Click the Source button.
4. Select an option from the Field Separation list.



The following options are available.



Select:	To:
No Fields	Specify that each frame is a complete video frame.
Upper First	Specify that the upper field (even) is generated first.
Lower First	Specify that the lower field (odd) is generated first.
