Rendering and exporting
Last updated 12/21/2009
Note: If you are going to use the resulting movie in another After Effects composition, enter a small value (less than 5) in
the Key Frame Every field or deselect the Key Frame Every option. The presence of key frames greatly increases the
memory required to edit and render a movie.
8 Click OK.
9 If your compressor choice supports different image color depths, choose the appropriate color depth in the Output
Module Settings dialog box.
10 Specify other settings in the Output Module Settings dialog box, and then click OK.

Render and export a composition to OMF (Windows only)
You can render a composition to the OMF (Open Media Framework Interchange) format to generate Avid media (or
essence) files; these files contain only media —not metadata or project data. Each OMF codec has a fixed frame size
and frame rate, depending on the output resolution you choose. Make sure that the composition or render settings are
set appropriately: If you use an unsuitable frame size or frame rate, After Effects doesn’t render the file and returns an
error displaying the expected frame size or frame rate.
The OMF file format doesn’t support audio, so any audio tracks aren’t exported, but you can output audio tracks
separately, if desired.
1 In the Render Queue panel, click the Output Module template name to open the Output Module Settings dialog box.
2 From the Format menu, select OMF.
3 Click Format Options.
4 Choose a format (NTSC or PAL), an AVR (Avid Video Resolution) codec, and an OMF version.
Note: OMFI version 1.0 is supported for backward compatibility with older Avid systems.
