Video and still picture frames have a frame aspect ratio, and the pixels that make up the frame have a pixel aspect ratio. Some cameras can record various frame aspect ratios, and different video standards use different pixel aspect ratios. You set the frame and pixel aspect ratios for an Adobe Premiere Pro project when you create it. Once they are set, you cannot change them for that project. You can, however, use assets created with different aspect ratios in that project. Adobe Premiere Pro automatically tries to compensate for the pixel aspect ratio of source files. If an asset still appears distorted, you can manually specify its pixel aspect ratio. It's important to reconcile pixel aspect ratios before reconciling frame aspect ratios, because an incorrect frame size can be due to a misinterpreted pixel aspect ratio. Frame aspect ratio Frame aspect ratio describes the ratio of width to height in the dimensions of an image. For example, DV NTSC has a frame aspect ratio of 4:3 (or 4.0 width by 3.0 height) and a typical widescreen frame has a frame aspect ratio of 16:9. Many cameras that have a widescreen mode can record using the 16:9 aspect ratio. Many films have been shot using even wider aspect ratios. April 1, 2008

Aspect ratios
About aspect ratios
An aspect ratio specifies the ratio of width to height. Video and still picture frames have a frame aspect ratio, and
the pixels that make up the frame have a pixel aspect ratio. Some cameras can record various frame aspect ratios,
and different video standards use different pixel aspect ratios.
You set the frame and pixel aspect ratios for an Adobe Premiere Pro project when you create it. Once they are set,
you cannot change them for that project. You can, however, use assets created with different aspect ratios in that
project.
Adobe Premiere Pro automatically tries to compensate for the pixel aspect ratio of source files. If an asset still
appears distorted, you can manually specify its pixel aspect ratio. It's important to reconcile pixel aspect ratios before
reconciling frame aspect ratios, because an incorrect frame size can be due to a misinterpreted pixel aspect ratio.
Frame aspect ratio
Frame aspect ratio
describes the ratio of width to height in the dimensions of an image. For example, DV NTSC has
a frame aspect ratio of 4:3 (or 4.0 width by 3.0 height) and a typical widescreen frame has a frame aspect ratio of
16:9. Many cameras that have a widescreen mode can record using the 16:9 aspect ratio. Many films have been shot
using even wider aspect ratios.
