The specific file formats that you can export to using QuickTime depend on how you’ve configured QuickTime. If
you install new export modules as they become available from Apple or other parties, those modules appear in the
File > Export menu in After Effects.
For more information about QuickTime effects and file formats supported by QuickTime, see QuickTime Help.

Render with OpenGL
OpenGL is a set of standards for high-performance processing of 2D and 3D graphics for a wide variety of applica-
tions. For After Effects users, OpenGL provides fast, high-quality rendering for previews and final output by moving
rendering from the CPU to the OpenGL hardware (GPU).
To use OpenGL in After Effects, you’ll need an OpenGL card that supports OpenGL 2.0 and has Shader support and
support for NPOT (Non Power of Two) textures.
Note: After Effects provides limited support for OpenGL 1.5 on Macintosh computers with PowerPC processors.
Feature support in After Effects is dependent on the OpenGL hardware; contact the hardware manufacturer for
details. When you first start After Effects, it attempts to determine if your OpenGL card meets the requirements, and
then enables or disables OpenGL as appropriate.
For information regarding specific OpenGL hardware, visit the After Effects section of the Adobe website at
