Setting pixel aspect ratio for compositions

Most computer monitors use square pixels, while ITU-R 601 (D1) and DV video use rectangular pixels. The Pixel Aspect Ratio option compensates for the rectangular pixels of D1 video format. Set the pixel aspect ratio that corresponds to your final output format. (See Setting pixel aspect ratio.)

If you intend to create a movie for the D1 output format, choose D1 NTSC or D1 PAL.

For more information about D1 format, see About D1, DV, and various pixel aspect ratio footage.

Note: The correct pixel aspect ratio for D1 NTSC or D1 PAL is chosen automatically when you choose the corresponding preset item.
