About nested sequences

A nested sequence is a sequence placed within another sequence. You can use it to build complex edits and layered structures. Each nested sequence appears as a single, linked video or audio clip, even though its source may include multiple tracks with different timebases, frame sizes, or pixel aspect ratios.

You can move, trim, and apply effects to nested sequences like any other clip. Any change you make to the source sequence automatically updates in all its nested instances.

Why use nested sequences

Nesting sequences saves time and helps you work efficiently when creating multi-layered edits. It also allows creative flexibility in applying transitions and effects.

• Reuse sequences efficiently: Create a complex sequence once and reuse it across multiple projects or timelines without needing to rebuild it.
• Apply different looks: Add distinct effects to each instance of a nested sequence while keeping the same base content.
• Simplify your workspace: Combine multiple layered tracks into a single nested clip to keep your timeline clean and reduce the risk of accidental edits.
• Build advanced effects: Create transitions within transitions or picture-in-picture effects by nesting sequences, each containing its own clips, transitions, and effects.

Things to remember when nesting sequences

• Avoid nesting a sequence within itself or one that contains a 16-channel audio track.
• Expect a longer processing time since each nested instance references multiple clips.
• Note that changes to the source sequence are reflected in all nested versions, but the duration remains the same.
• Remember that the initial duration includes empty space at the start of the source, not at the end.
• Set In and Out points as needed. Trimming affects only the nested clip, not the source.
• If the source sequence is shortened, the nested clip may display black video or silent audio, which you can trim.
