The Player

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 through the Player options, except for the repeat mode and f-stop. You can 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.
