Work with composition settings

You can enter composition settings manually, or you can use composition settings presets to automatically set frame size (width and height), pixel aspect ratio, and frame rate for many common output formats. You can also create and save your own custom composition settings presets for later use. Resolution, Start Timecode, Duration, and Advanced composition settings are not saved with composition settings presets.

Note: The limit for composition duration is three hours. You can use footage items longer than three hours, but time after three hours does not display correctly.
  • To change composition settings, select a composition in the Project panel or activate the Timeline or Composition panel for a composition, and then choose Composition > Composition Settings, or press Ctrl+K (Windows) or Command+K (Mac OS).
  • To save a custom composition settings preset, set Width, Height, Pixel Aspect Ratio, and Frame Rate values, and then click the Save button .
  • To delete a composition settings preset, choose it from the Preset menu, and click the Delete button .
  • To restore default composition settings presets, Alt-click (Windows) or Option-click (Mac OS) the Delete button  or the Save button .
