Effects names the first frame [file_name]_00038. The Use Comp Frame Number option adds the starting frame

of rows or columns of pixels to be added or subtracted from the top, left, bottom, and right sides of the movie. Use
positive values to crop, and use negative values to add rows or columns of pixels. Select Region Of Interest to render
only the region of interest selected in the Composition or Layer panel.
By adding one row of pixels to the top and subtracting one row from the bottom of a movie, you can change the field

Specifies the sample rate, sample depth (8 Bits or 16 Bits), and playback format (Mono or Stereo).
Audio Output
Choose a sample rate that corresponds to the capability of the output format. Choose an 8-bit sample depth for
playback on the computer, and a 16-bit sample depth for CD and digital audio playback or for hardware that supports
16-bit playback.
Use a post-render action
You can use post-render actions to automate simple tasks that occur after a composition is rendered.
A common example of the use of post-render actions is with pre-rendering: Choosing Composition > Pre-render
adds the selected composition to the render queue and sets the Post-Render Action option to Import & Replace
Usage.
Note: You choose Post-Render Action options in the Output Module group, so be aware that changing the Output
Module template could also change the Post-Render Action option. (See "Work with output module settings" on
page 594.)
Expand the Output Module group in the Render Queue panel by clicking the arrow to the left of the Output
1
Module heading.
Choose one of the following from the Post-Render Action menu:
2
Performs no post-render action. This option is the default.
None
Imports the rendered file into the project as a footage item when the rendering is complete.
Import
Imports the rendered file into the project and substitutes it for the specified item. Drag the
Import & Replace Usage
pick whip to the item to replace in the Project panel to specify it.
Use the Import & Replace Usage option to create a chain of dependent render items. For example, you can set one
render item to use a watch folder and multiple computers to create a still-image sequence, and then the next render
item can render a single movie file from that still-image sequence. (See "Network rendering with watch folders" on
page 618.)
Sets the rendered file as a proxy for the specified item. Drag the pick whip to the item in the Project panel
Set Proxy
item to specify it.
