Frame rate options overview
There are two ways to modify the rate at which a transcoded file
plays back. You can
, or you can
(which may or may not have an effect on playback speed). If
you do change the frame rate, there are special options for
working with footage, including and
.
The controls that make speed modifications are located in the
General inspector and in the Video inspector.
Retime video and audio
To retime video, you make changes to properties in both the
General inspector and the Video inspector. (You can create some
effects by modifying properties in only one of the inspectors.)
The Retiming section in the General inspector allows you to define
a new speed setting for the clip. You can specify a percentage,
such as 50% to create a slow-motion effect, or 200% to create a
fast-motion effect. You can identify a precise number of frames
and allow the software to calculate the percentage for you; or you
can instruct Compressor to renumber the current frames into a
different frame rate in order to convert a file from one frame rate
to another without adding or deleting any frames.
In the Video Properties section of the Video inspector, you can set
a specific frame rate for the transcoded file. By default, this
property is set to “Automatic,” which applies the frame rate of the
source file to the output file.
