Preview 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 tools—see Utilities. Or you can add and connect such a node inside your composition to explicitly convert your material to 8 bits. Also, see Initialization Variables for the initialization variable for previewing video.

When previewing a composition's video on a broadcast monitor, you can work with multiple Players.

To preview video on a broadcast monitor:

1. Open a composition.
2. Create, import, or link to material that is RGB or RGBA.
   Tip If the material is 16 or 32 bits, you can convert it to 8 bits by using a display modifier in the Player or by adding a Convert Depth node to the process.
3. Click the Player which contains the video you want to display on the broadcast monitor.

   The Player displays the image generated by the tools in your dependency graph.

   NoteManipulators are not shown in the video preview.
4. In the transport controls, press Play to play the composition.
