merge_movie_scenes is built specifically for combining a list of video clips into one continuous video — the tool most people mean when they say 'merge my videos', originally built for stitching AI-generated movie scenes but equally usable on any set of clips.
It handles transitions and audio between clips as first-class settings, which is what separates it from a plain concatenation.

Merge multiple video clips into a single movie. Use after generating individual scene videos to combine them into one final video.
What to tell the agent
Versely's agent maps this plain-English request directly onto merge_movie_scenes. You don't need to know the parameter names — just describe what you want.
“Merge these three video clips into one video with a crossfade transition between each.”
How it works
1. Gather your clip URLs
video_urls takes the list of clips to merge, in the order you want them to play.
2. Pick a transition
transition_type and transition_duration control how each clip cuts into the next — a hard cut, a crossfade, or another style.
3. Decide how audio is handled
audio_handling controls what happens to each clip's own audio track as they're merged — keep it, drop it, or crossfade it along with the video.
4. Render
You get back one combined video.
What it costs
Billed as a standard merge operation. Ask the agent for estimate_cost before merging a long list of clips.
The formula behind that number: What does editing a video cost if I keep changing it? — charges per finished export, so iteration is free and the count is the whole bill.
Limits & things to know
- This merges whole clips in sequence — for mixing images and video together, or trimming per-clip ranges as part of the merge, use compose_video_with_overlay instead.
- Transition style and audio handling are set once for the whole merge, not customized per individual seam.
Who uses this
- Combining separately generated AI video scenes into a finished short
- Stitching multiple camera takes into one sequence
- Assembling a multi-part cutdown from several source clips
Frequently asked questions
Can I control the transition between clips?+
Yes — transition_type and transition_duration control how each clip cuts into the next, applied consistently across the merge.
What happens to each clip's original audio?+
audio_handling controls that — you can choose how each clip's own audio track behaves as they're combined.
Can I mix in still images along with the videos?+
Not with this tool — merge_movie_scenes is video-only. To combine images and videos together, use compose_video_with_overlay instead.
