Retime a layer.

Adjust a layer's timeline interval and source relationship.

Change a clip’s place and trim while retaining its natural playback speed. The coastal film begins at 1.1s and reads source 1.1–8s, replacing the original full-duration layer. Its active and source ranges remain explicit and separately editable.

Try it in your agent.

Use this prompt as a starting point. Review the result, then ask for the details you want to change.

A prompt to start from

Use Strata. Create an eight-second silent Strata timing study. Set “Arrive / on cue.” at left and a calm Sky frame at right. The coastal Video enters at 1.1 seconds. Implement a real start trim: both activeRange.start and sourceRange.start advance 1100 ms, with both durations reduced to 6900 ms so the playback rate remains 1x. Keep a separate before source with the original 0–8s layer. The target is timing data; do not fake the entrance with opacity or claim an unavailable retime API.

A few useful details.

How do I try this with my agent?
