System information

Item Description
Pixel format Choose a setting from the drop-down list to indicate whether you
want to perform video processing (compositing, scaling, previewing,
rendering, and most video plug-ins) using 8-bit or 32-bit, floating-
point arithmetic.
n 8-bit: Performs video processing using 8-bit arithmetic and in
the video (studio RGB, or 16-235) color space.
n 32-bit floating point (video levels): Performs video
processing using 32-bit arithmetic and in the video color
space.
n 32-bit floating point (full range): Performs video processing
using 32-bit arithmetic and in the full-range color space.
The 32-bit floating point settings allow greater precision for
processing video, but require significantly more processing
power than working with 8-bit video.
Tips:
n 32-bit floating point (video levels) is recommended when
working with 10-bit YUV input/output or when using
xvYCC/x.v.Color media.
n When using 8-bit input/output, the 32-bit floating point
(video levels) setting can prevent banding from compositing
that contains fades, feathered edges, or gradients.
n Video plug-ins and media generators that support floating-
point processing are included in the 32-bit floating point
folder in the Transitions, Video FX, Media Generators,
Compositors, and Plug-In Manager windows.
n If you're creating a 32-bit project, you can increase
performance during editing and playback by using the 8-bit
setting during editing and switching to 32-bit floating point
(video levels) before rendering.
Compositing gamma When you choose 32-bit floating point (full range) from the Pixel
format drop-down list, you can choose a compositing gamma value.
n 1.000 (Linear): The default setting when you choose 32-bit
floating point (full range) from the Pixel format drop-down
list.
n 2.222 (Video): Processing in 8-bit video is always performed
using a setting of 2.222.
View transform Choose the reference view transform to use for the project. For more

project" on page 428.
