Freeze Frame

In its simplest form, highlight a region of the track to freeze, drop the freeze frame effect on the highlighted region, and the lowest numbered frame in the affected area will play throughout the entire region. Freeze Frame has an enabled option which can be keyframed. Regions of a freeze frame effect which are enabled, repeat the lowest numbered frame since the last keyframe. This has unique possibilities.

If a freeze frame effect has a keyframe in the middle of it set to enabled, the frame in the middle is repeated in the entire effect.
If a freeze frame effect has several keyframes, each set to enabled, every time a keyframe is encountered the frame under it becomes the frozen one.
If a freeze frame effect alternates between enabled and disabled, each time an enabled keyframe is encountered the frame under it is replicated until the next disabled keyframe. The disabled regions play through.
