The timeline environment enhances the editing process by providing tools that allow you to work with all the video and audio elements of your sequence.

There can be multiple video tracks and audio tracks on the timeline. Each video track can consist of multiple layers. Arranged vertically, a multilayer video track provides the framework for timeline compositing in Smoke.

When editing to the timeline, you are not restricted to using video or images of a particular frame rate or resolution. When you record a clip in a non-native project resolution to the timeline, the clip is automatically resized. You can continue to apply Resize options such as letterbox or cropping.
