Changing the Aspect Ratio for a Project
You typically set the aspect ratio for a project when you create the project (see “Creating a New
Project” on page 50). The aspect ratio can be changed at any time, however this will affect any
titles that you have created, so the titles also need to be recreated at the new aspect ratio.

For HD projects, only the 16:9 aspect ratio is available as this is the only aspect ratio allowed in
the HD standard.
To change the aspect ratio for a project, do one of the following:
t Click the Format tab in the Project window, then click the Aspect Ratio menu, and select
either 4:3 or 16:9, depending on the aspect ratio you want to use.

t Right-click in the monitor window in Source/Record or in Trim mode, select Project Aspect

use.Right-click in the monitor window in editing or in Trim mode, select Project Aspect
Ratio, and then select either 4:3 or 16:9, depending on the aspect ratio you want to use.
Your Avid editing application changes the aspect ratio of the monitors, and resizes and
repositions any material in the project’s sequences that does not match the new aspect ratio
so that it conforms to that aspect ratio. You see these changes when you next open and view
an affected sequence. You do not need to re-edit the media into the sequence, and the source
media remains unchanged.
To recreate titles at the new aspect ratio:
1. After you have switched to the new aspect ratio, select a clip on the timeline that has a title
that you need to recreate.
2. From the main menu, select Clip > Recreate Title Media.
A new title will be recreated in the bin with the new aspect ratio.
3. Continue recreating all other titles on your timeline using the same steps.
