Project Settings > General to inspect the project’s aspect ratio. In addition, you can use the
File > Interpret Footage command to inspect and change the pixel aspect ratio that Adobe
Premiere Pro assumes for individual source clips in the Project window. By ensuring that
all files are interpreted correctly, you can combine footage with different ratios in the same
project and generate output that doesn’t distort the source images.
To set the pixel aspect ratio for imported files:
1
Select the file in the Project window.
2
Choose File > Interpret Footage, specify options in the Pixel Aspect Ratio section, and
click OK. For information about options in the Conform To pop-up menu, see “Common
pixel aspect ratios for imported files” on page 101.
Common pixel aspect ratios for imported files
It is important to set the pixel aspect ratio for a file at its original ratio, not the ratio of the
final output. You can set pixel aspect ratios for clips and projects with these approximate
values:
Square Pixels
Uses a 1.0 pixel aspect ratio. Use this setting if your source clip has a 640
x
480 or 648 x 486 frame size, or if the file was exported from an application that doesn’t
support nonsquare pixels.
D1/DV NTSC
Uses a 0.9 pixel aspect ratio. Use this setting if your source clip has a 720 x
480 or 720 x 486 frame size and you want it to maintain a 4:3 frame aspect ratio. This
setting can also be appropriate for clips that were exported from an application that works
with nonsquare pixels, such as a 3D animation application.
D1/DV NTSC Widescreen
Uses a 1.2 pixel aspect ratio. Use this setting if your source clip
has a 720 x 480 or 720 x 486 frame size and you want it to maintain a 16:9 frame aspect
ratio.
D1/DV PAL
Uses a 1.0666 pixel aspect ratio. Use this setting if your source clip has a 720
x
576 frame size and you want it to maintain a 4:3 frame aspect ratio.
D1/DV PAL Widescreen
Uses a 1.4222 pixel aspect ratio. Use this setting if your source
clip has a 720 x 576 frame size and you want it to maintain a 16:9 frame aspect ratio.
Anamorphic 2:1
Uses a 2.0 pixel aspect ratio. Use this setting if your source clip was
anamorphically transferred from a film frame with a 2:1 aspect ratio.
D4/D16 Standard
Uses a 0.9481481 pixel aspect ratio. Use this setting if your source clip
has a 1440 x 1024 or 2880 x 2048 frame size and you want it to maintain a 4:3 frame
aspect
ratio.
D4/D16 Anamorphic 8:3
Uses a 1.8962962 pixel aspect ratio. Use this setting if your
source clip has a 1440 x 1024 or 2880 x 2048 frame size and you want it to maintain an
8:3
frame aspect ratio.

Using square-pixel footage for output to DV
You can use square-pixel footage in a DV project and generate output that does not
appear distorted. Adobe Premiere Pro either upsamples (increases) the resolution or
downsamples (decreases) the resolution of a file that does not match the project frame
size. Because downsampling results in a higher-quality image, it is best to create files that
are larger than the project’s frame size so that Adobe Premiere Pro does not have to
upsample and enlarge the file.
To use square-pixel files in a D1 or DV project:
