When using the Print to Video and Edit to Tape commands, you can control the quality
of video being output to tape independently of the real-time playback video quality in
the Canvas and Timeline.
When this option is selected, video is always output to tape at the highest quality.
Areas of your sequence that won’t play back at full resolution in real time must be
rendered prior to output.
Use Playback Settings
Final Cut Pro uses the selected real-time effects playback settings when outputting
your sequence to tape. If, as a result, your sequence will output at less than full quality,
you are warned of this prior to output. Outputting to tape at draft quality is useful for
quickly creating sample tapes of your program when you don’t have the time to render
all necessary effects first.
