Previewing Video
If your system has the appropriate hardware, you can preview your work on
a broadcast video monitor. Video previewing is available for Composite on
Windows 32-bit. Depending on the level of performance of the video output
card and the graphics card, as well as the host system CPU, Composite can
achieve real-time previewing of 1920x1080 24P resolutions (and below) of
8-bit RGB or RGBA material.
Composite will only display 8-bit pixel formats on the video preview device.
To display 16-bit float and 32-bit float images, you must convert them to 8
bits. You can do this by using a display modifier in the Player that converts
to 8 bits, such as the sRGB, 3D LUT, or Convert Depth toolssee
About Utilities
on page 805. Or you can add and connect such a node inside your composition
to explicitly convert your material to 8 bits. Also, see
Initialization Variables
on page 873 for the initialization variable for previewing video.
Setting Up Video Previewing
To preview video on a broadcast monitor, you will need the AJA Xena 2K
video card and its accompanying driver installed on your system. For more
information, refer to the Composite Installation Guide for Windows.
