Converting Movies - Adobe AFTER EFFECTS CS3 PROFESSIONAL User Manual

Open the Render Queue panel on each computer and click Render. You do not need to start rendering on each
8
computer simultaneously, but to ensure equal workloads, start them at approximately the same time. As each
computer finishes rendering a frame, After Effects searches the Output folder for the next unrendered frame and
starts rendering again.
You can stop and start any computer at any time. However, if you stop a computer without starting it again, the
9
frame that it was rendering may not be finished. If one or more computers stop during rendering, starting any one
computer will ensure that all frames in the sequence get rendered.

Overflow volumes and segment settings
Overflow volume and segment settings are in the Output Preferences category.
Choose Edit > Preferences > Output (Windows) or After Effects > Preferences > Output (Mac OS).
When the disk volume to which After Effects is writing files is full, it can continue writing files to an overflow volume.
You can set preferences to make After Effects render to up to six different disk volumes, as specified in the Overflow
Volumes list. You can change the amount of disk space remaining on a volume before After Effects considers it an
overflow by modifying the Minimum Diskspace Before Overflowing value.
Note: The log file reports when a render overflows.
After Effects can also render sequences and movie files into segments that are limited to a specified number of files
or by file size; this is useful when preparing a movie for a medium such as CD-ROM, for which file or folder size may
need to be limited to chunks of 650 MB or less. Use the Segment Movie Files At value to set the maximum size for
segments in megabytes. Use the Segment Sequences At value to set the maximum number of still-image files in a
folder.
Audio is also rendered in segments, the length of which is set by the Audio Block Duration value. If you hear pops
in audio, you may be hearing a faulty transition between segments; if you have enough memory, increase the Audio
Block Duration to be longer than your output to avoid this problem.

Converting movies

Convert footage items between video formats
You can use After Effects to convert one type of video to another. When converting video, keep the following in mind:
• Changes in resolution may result in a loss of picture clarity, especially when up-converting from a standard-
definition format to a high-definition format.
