Transcode Clips
Use this to convert a video or audio clip from one codec/format to another.
Choose the source file and a profile that represents the desired destination codec/format. Optionally change the destination path and file name and hit Start.
Transcoding a clip should be faster than loading the clip into the timeline and re-encodeing it into a different format.
