USING ADOBE PREMIERE PRO
Managing assets
When you capture or import NTSC footage with the ATSC frame size of 704x480, the D1 frame size of 720x486, or the
DV frame size of 720x480, Premiere Pro automatically sets the pixel aspect ratio for that asset to D1/DV NTSC (0.91).
When you capture or import footage with the HD frame size of 1440x1080, Premiere Pro automatically sets the pixel
aspect ratio for that file to HD 1080 Anamorphic (1.33). When you capture or import PAL footage with the D1 or DV
resolution of 720x576, Premiere Pro automatically sets the pixel aspect ratio for that file to D1/DV PAL (1.094).
For other frame sizes, Premiere Pro assumes that the asset was designed with square pixels and changes the pixel aspect
ratio and frame dimensions in a way that preserves the asset image aspect ratio. If the imported asset is distorted, you
can change the pixel aspect ratio manually.
When you drag an asset into a sequence, Premiere Pro centers the asset in the program frame by default. Depending
on its frame size, the resulting image could be too small or overcropped for the needs of the project. If so, you can
change its scale. You can do this manually or have Premiere Pro do it automatically whenever you drag an asset into a
sequence.
It is always a good idea to make sure that files are interpreted correctly. You can read asset frame dimensions and pixel
aspect ratio near the preview thumbnail and in the Video Info column of the Project panel. You can also find this data
in the asset Properties dialog box, the Interpret Footage dialog box, and the Info panel.

Fix aspect ratio distortion
The sequence settings preset you choose when you create a sequence sets the frame and pixel aspect ratios for the
sequence. You can't change aspect ratios after you create the sequence, but you can change the pixel aspect ratio that
Premiere Pro assumes for individual assets. For example, if a square-pixel asset generated by a graphics or animation
program looks distorted in Premiere Pro, you can correct its pixel aspect ratio to make it look right. By ensuring that
all files are interpreted correctly, you can combine footage with different ratios in the same project. Then you can
generate output that doesn't distort the resulting images.

Note: When using Photoshop to generate images for use in video projects, it's best to use the Photoshop preset named for
the video format you'll use. Using the preset ensures that your images are generated with the correct aspect ratio.
