Path

Location of the composition.

Description

Information you can enter about the composition.

Primary Output

Select the output to use as the principal output of the composition. The format, width, height, image aspect ratio, pixel aspect ratio, and rate settings are those of the primary output—see Primary Output.

Format

Lets you set the resolution of the composition by specifying a known film or video format. The format you select is linked to the following: width, height, image and pixel ratio, and rate. Select Custom to define a non-standard format.

Width, Height

Width and height (in pixels). These values, together with ratios and rate, may correspond to a predefined format, in which case the format is automatically selected. Otherwise, the format selected is Custom.

Image Aspect Ratio and Pixel Aspect Ratio

The ratio is expressed as a fraction representing the proportion, width:height, of the image. This value, together with width, height, pixel ratio and rate, may correspond to a predefined format, in which case the format is automatically selected. Otherwise, the format selected is Custom. Image and pixel ratio are linked; changing one updates the other.

Rate

Frame rate expressed as frames per second (fps). For a given format, a limited number of rates are available. To set a non-standard rate for a given format, change the format to Custom

Channels

Set the image channel for the primary output: RGB, RGBA, A.

Depth

Select the bit depth (8, 16, or 32 bits) for the primary output.

Start, End, Duration

Set the start, end, and duration of the primary output. End is exclusive, so Duration = End - Start. Example Start=0, End=30, Duration=30. Start=1, End=31,Duration=30. And so on

Poster

Frame used for proxies, defaults to start value.

Mark In/Mark Out

Set the in point and out point for the primary output

Repeat

Select the default repeat mode (Hold, Loop, Ping-Pong, No Repeat) for primary output when you play it.
