Specifying Sequence Settings for Anamorphic Media

When you use 16:9 anamorphic media in a sequence, you need to select the Anamorphic option in the Sequence Settings window. There are two ways you can do this:

Make sure you turn on the Anamorphic 16:9 option before you add any clips to your sequence. If a 16:9 clip is edited into a 4:3 sequence, the clip is scaled to fit in the 4:3 frame, causing the clip to be letterboxed. If the sequence is then changed to 16:9 without first removing the edited clip, the Scale and Distort parameters applied to the clip still remain.

To turn on the Anamorphic option after you’ve created a sequence
  1. Open the sequence in the Timeline.

  2. Choose Sequence > Settings.

  3. Select the Anamorphic 16:9 checkbox, then click OK.
