enter a value in the text field to set the

your output file.
Encode for: Select a button to have Compressor transcode
the output file at either the best quality (so that the file will play

devices as possible will play the file).
Compatible with: This list shows devices that will play the
transcoded file (compatible device types are marked with a
green circle that contains a checkmark ). When you change
the setting’s properties (frame size, frame rate, and so on), the
compatibility list automatically updates.
