USING ADOBE PREMIERE PRO 119 Managing assets Pixel aspect ratio describes the ratio of width to height of a single pixel in a frame. Pixel aspect ratios vary because different video systems make various assumptions about the number of pixels required to fill a frame. For example, many computer video standards define a 4:3 aspect ratio frame as 640 pixels wide by 480 pixels high, which results in square pixels. Video standards such as DV NTSC define a 4:3 aspect ratio frame as 720x480 pixels, which results in narrower, rectangular pixels because where more pixels lie within the same frame width. The computer video pixels in this example have a pixel aspect ratio of 1:1 (square). The DV NTSC pixels have a pixel aspect ratio of 0.91 (nonsquare). DV pixels, which are always rectangular, are vertically oriented in systems producing NTSC video and horizontally oriented in systems producing PAL video. Premiere Pro displays clip pixel aspect ratio next to the clip image thumbnail in the Project panel. If you display rectangular pixels on a square-pixel monitor without alteration, images appear distorted; for example, circles distort into ovals. However, when displayed on a broadcast monitor, the images appear correctly proportioned because broadcast monitors use rectangular pixels. Premiere Pro can display and output clips of various pixel aspect ratios without distortion. Premiere Pro attempts to automatically reconcile them with the pixel aspect ratio of your project. You could occasionally encounter a distorted clip if Premiere Pro interprets pixel aspect ratio incorrectly. You can correct the distortion of an individual clip by manually specifying the source clip pixel aspect ratio in the Interpret Footage dialog box. You can correct similar misinterpretations of groups of same-size files by editing the file Interpretation Rules.txt.

Pixel aspect ratio

describes the ratio of width to height of a single pixel in a frame. Pixel aspect ratios vary because

different video systems make various assumptions about the number of pixels required to fill a frame. For example,

many computer video standards define a 4:3 aspect ratio frame as 640 pixels wide by 480 pixels high, which results in

square pixels. Video standards such as DV NTSC define a 4:3 aspect ratio frame as 720x480 pixels, which results in

narrower, rectangular pixels because where more pixels lie within the same frame width. The computer video pixels in

this example have a pixel aspect ratio of 1:1 (square). The DV NTSC pixels have a pixel aspect ratio of 0.91 (nonsquare).

DV pixels, which are always rectangular, are vertically oriented in systems producing NTSC video and horizontally

oriented in systems producing PAL video. Premiere Pro displays clip pixel aspect ratio next to the clip image

thumbnail in the Project panel.

If you display rectangular pixels on a square-pixel monitor without alteration, images appear distorted; for example,

circles distort into ovals. However, when displayed on a broadcast monitor, the images appear correctly proportioned

because broadcast monitors use rectangular pixels. Premiere Pro can display and output clips of various pixel aspect

ratios without distortion. Premiere Pro attempts to automatically reconcile them with the pixel aspect ratio of your

project.

You could occasionally encounter a distorted clip if Premiere Pro interprets pixel aspect ratio incorrectly. You can

correct the distortion of an individual clip by manually specifying the source clip pixel aspect ratio in the Interpret

Footage dialog box. You can correct similar misinterpretations of groups of same-size files by editing the file

Interpretation Rules.txt.

<<Premiere Pro CS3 and earlier used pixel aspect ratios for standard-definition video formats that ignore the concept

of clean aperture. By not accounting for the fact that clean aperture differs from production aperture in standard-

definition video, the pixel aspect ratios used by After Effects CS3 and earlier were slightly inaccurate. The incorrect

pixel aspect ratios cause some images to appear subtly distorted.

Note:

The clean aperture is the portion of the image that is free from artifacts and distortions that appear at the edges of

an image. The production aperture is the entire image.

For details about the corrected pixel aspect ratios in Premiere Pro CS4 and later (as well as other applications), see the

Adobe website
