Player View Default Settings

When you add a Player view to a viewport, it has the following settings by default. You can adjust all of these, except for the repeat mode and f-stop, through the Player options. You adjust the repeat mode in the Player controls—see Using the Player Controls in the Interface Fundamentals chapter.

Displays the output of the composition.
Follows master time.
Plays all frames and updates at each frame.
Sets the f-stop to 0.00.
Plays at the native rate of the composition.
Does not display any guides apart from the frame outline, or any masks.
Displays RGB.
Has repeat mode set to No Repeat.
Does not correct pixel aspect ratio.
Does not use a display modifier (LUT).

Calculating Image Size in Composite

All Composite images live on a 2D plane.Composite and PXL use a Cartesian coordinate system to identify points on the plane.This plane and reference system are called the Image Reference Frame (IRF). This reference system has an origin and perpendicular X and Y axes. Units along the X and Y axes have the same length.By default, Composite images are centered at the origin of the IRF.In Composite, pixels at the highest resolution have a height of 1 IRF unit, and have a width equal to their pixel aspect ratio, i.e. 1 IRF unit for 1080P HD material, 0.9 for NTSC material, and 16/15 (1.0667) for PAL material.

For images with non unit pixel aspect ratios, the height of a pixel is 1, but the width of a pixel is equal to its aspect ratio (e.g. 0.9 for NTSC). Using IRF units simplifies image manipulation: for example, translating an image by 10 IRF units will move the image by the same amount, regardless of the direction of the translation, horizontal, vertical, or any combination thereof.
