Compressor process the output le using your shared computer group. For more information,

Note: Job segmenting is not available when outputting an MPEG-4 audio le or when the
Multi-pass checkbox is selected in the Video inspector.

Retiming
This section contains one property:
•
Set duration to: Sets the processing algorithm used to adjust the frame rate during transcoding.
Select one of the following options:
•
[Percentage] of source: Modies the output clip’s speed by a percentage of the source clip’s
speed. Enter a value in the percentage eld or choose a preset value from the adjacent
pop-up menu (with a downward arrow).
•
[Total duration]: Sets the duration of the clip. Enter a timecode duration in the eld or click
the arrows to increase or decrease the time.
•
So source frames play at [frame rate] fps: Nondestructively changes the playback speed of the
clip, without discarding frames or creating new frames. This setting has no eect unless the
“Frame rate” value in the Video inspector is dierent than the source le’s frame rate. For
example, if you add a 10-second source le with a frame rate of 24 fps to Compressor, set the
“Frame rate” property in the Video inspector to 25 fps, and then select “So source frames play
at 25 fps” in the General inspector, the duration of the transcoded clip (at 25 fps) is 9 seconds
and 15 frames.
Note: This option is not available when outputting an MPEG-4 audio le.
