Transcode a portion of a clip
Although Geometry (cropping and scaling) and Filters adjustments are displayed instantly in the
Preview window, Encoder pane and Frame Controls pane settings are not. To preview Encoder pane
and Frame Controls pane settings, do a test transcode of a small section of your source media file.
You can use the Preview window to set In and Out points to transcode a portion of your media
file rather than all of it.
