Merge Videos node

The Merge Videos node concatenates up to 10 video clips into a single video, in the order they are wired in.
How it works
Wire two or more Video Generation nodes (or uploaded clips) into the clips handle. The node runs ffmpeg to concatenate the clips — joining both the
video and audio tracks seamlessly — and returns one merged clip.
Configuration
- None — the node takes all its inputs from the wiring.
Example
Video Generation (clip 1) ─┐
Video Generation (clip 2) ─┼─▶ Merge Videos ─▶ Output
Video Generation (clip 3) ─┘ The merged result ({ dataUrl, mime }) is the payload for downstream nodes.
Notes
- Requires at least 2 clips — the engine fails with a clear message otherwise.
- Clips are joined in wiring order.
- The merge runs server-side and needs
ffmpeg, which ships with the deployment.
