Sign in to pick a video from your creations or upload one.
Up to 10 clips. Clips of different sizes are scaled to match the first one. No credits are charged for merging.

About the Video Merger
AI video engines make clips of 5 to 30 seconds. A story, an ad or a music video is several of them in a row. The merger joins up to ten clips in the order you pick and gives you one MP4 to download or keep editing.
Every clip is scaled to the size of the first one before joining, so there is no freeze or jump at the cut when your clips were made at different resolutions.
Join clips without an editor
Order, merge, download. Below: how it works and how to get seamless joins.

- Extend the last frame of one clip to lead into the next for smoother joins.
- Keep clips in the same aspect ratio when the video is for one platform.
- Add music and captions afterwards in the AI video editor.
Why merge here
Your clips are already in your creations, so there is nothing to download and re-upload. The merger matches sizes automatically, charges no credits, and hands the result to the extender, upscaler or editor in one click.
