Tracks Tab 179
Copy
The Copy option enables you to designate tracks that should be copied into the final output
movie without processing and encoding. This option is also useful for movies where you need
to encode (or re-encode) only one track and simply copy the other into the final file.
For example, if you have a movie that already has a finished audio track but still need to encode
the video track, you can select Copy for the audio and Process for the video.
The Copy option is also useful for QuickTime movies that have tracks, such as sprites or text,
that should be copied to the final file without processing. Copying these files preserves their
unique qualities instead of turning them into pixels in the video track.
Process
The Process option causes the selected track to be processed and compressed when added to
the final output movie. This is normally how you handle video and audio tracks. It’s possible
to not process certain track types, such as QuickTime music, so Process is not always an option.
Preload
Forces the player to preload the track in RAM before it can be played. Useful for automatically
playing high bitrate movies that would otherwise cause skipping. See “Enhanced Movie
Playback” on page 45.
Display High Quality
Enable to display the video track with a higher quality dithering, interpolated scale, or other
features (depending on the codec) during playback.
Other Tracks
Space is provided to allow for two other QuickTime tracks not specifically listed in the Tracks
tab. If you have a movie with a track type not listed, you must type in the four-letter track code
in the Other field.
