Protected region markers behave the same as other composition markers, except that when you nest a composition with protected regions, those markers can not be modified. Protected regions are composition markers with the Protected Region option enabled, with different handle icons to make it easy to identify.To trim the in or out point of the layer instead of time-stretching, hold the Option (macOS) or Alt (Windows) key and drag the in and out points.
For example, when you time-stretch a clip of 5 seconds that has protected regions of 2 seconds, to make it 10 seconds, the duration of the protected regions remains 2 seconds long. The feature preserves the duration of the protected regions. When you drag the in and out points of a composition that has one or more protected regions and it is nested into another composition, it time-stretches the composition instead of trimming.Responsive design preserves the animation time regardless of when the duration of the clip is extended or trimmed. This enables you to create complex animations and Motion Graphics templates that can responsively retime to align with a sequence in a project.įor example, you create a lower third and animate fade in/out and add responsive design-time. With this feature, the animation pins to the graphic or sequence and adapts to the edits you make to them. You can protect the intros, outros, and any arbitary region of a composition, and save the responsive design templates and reuse them in different projects to avoid duplicating and retiming. Adaptive time-stretching means that the the protected regions animate in the same amount of time even if you time-stretch the unprotected regions.
The feature enables adaptive time-stretching when a composition is nested or when it is exported as a Motion Graphics template. The Responsive Design - Time feature allows you to author adaptive motion graphics.
