Format 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
