To set the pixel aspect ratio for imported footage:
1 Select the footage in the Project window.
2 Choose File > Interpret Footage > Main.
3 Select a ratio from the Pixel Aspect Ratio pop-up menu and click OK.
If you are planning to render to the same pixel aspect ratio as your footage, you also need
to set the pixel aspect ratio for the composition.
To set the pixel aspect ratio for a composition:
1 Open the composition.
2 Choose Composition > Composition Settings.
3 Select a ratio from the Pixel Aspect Ratio pop-up menu and click OK.
In some circumstances, you may need to work on a monitor that doesn’t match the pixel
ratio, so that your working view doesn’t match the final output. You can correct the pixel
aspect for previewing purposes.
To correct pixel aspect distortion (for previewing only):
With the appropriate composition open, click the arrow above the vertical scroll bar in the
Composition window and choose Pixel Aspect Correction.
Using square-pixel footage for output to D1 or DV NTSC
You can use square-pixel footage in a D1/DV NTSC composition and generate output that
does not appear distorted. Note that the pixel aspect ratio is identical between D1 and DV,
but there is a slight difference in composition frame size. The steps that follow contain
information about issues discussed elsewhere in this guide. For more information on any
of the topics mentioned, see the index.
To use square-pixel footage when outputting to D1 or DV NTSC:
1 Prepare square-pixel footage that fills the entire frame using one of the following
methods:
• If your final output is DV, create and save it at a 720 x 534 frame size.
• If your final output is D1, create and save it at a 720 x 540 frame size.
