When material is brought into Backdraft Conform, it is assigned a particular scan mode that becomes part of the clip metadata. When you view clip information, the scan mode displayed is from the clip metadata tag. The scan mode metadata tag for a clip may be wrong, for example, if you specified the scan mode as being field 1 when importing it, and it was actually field 2.

You can correct this problem using the Change Dominance option of the Dominance tool in the Video menu. This option changes the scan mode metadata tag for a clip without changing the actual scan mode of the media on the framestore.

To change the scan mode metadata tag for a clip:

1. Display the Video menu and then enable Dominance.

   
   

2. From the Scan Mode Tools box, select Change Dominance.

   
   

3. From the Scan Mode box, select the scan mode metadata tag that you want to assign to the clip.
4. Select the source clip.
5. Specify the destination.

   A new clip with the specified metadata tag is processed.

You can also do this from the clip library Tools menu.

To change the scan mode metadata tag for clips from the clip library Tools menu:

1. Select a single clip or hold Ctrl and select multiple clips in the clip library.
2. Click Tools.

   
   

3. From the Tools menu that appears, choose Dominance.

   The Change Dominance controls appear.
