window to automatically follow the position of the playhead. For more information,
see “

tracks while using the JKL keys on either side of the Trim Edit window.

Visibility, Track Locking, and Audio Keyframe Options
 Warn if visibility change deletes render file: Making an entire track invisible
automatically deletes any render files associated with that track. Make sure you select
this option to see a warning before this occurs.
Note: As an alternative to hiding a track and losing its render files, you can make
individual items invisible, which preserves these render files. To find out how to
disable individual clip items, see “
Compositing and Layering ” on page 775.
 Record Audio Keyframes: When this option is selected, keyframes are recorded
whenever audio filter controls are adjusted.
Timeline Options Tab
This tab is used to set default options for new sequences. This is where you set the
default number of video and audio tracks for new sequences. Once a sequence is
created, you can change display options by choosing Sequence > Settings or by using
the Timeline display controls in the lower left of the Timeline. For more information, see
“
Timeline Basics ” on page 111.
