# Merge Video

Joining finished clips into one ordered video.

**Use it for:** Joining finished clips into one ordered video.

**What it can do:** Collect clips, reorder them, preview their sequence, then
export a combined MP4. A connected Storyboard supplies its videos in row order.

**Inputs:** Ready videos from Video nodes/video assets, or Storyboard's ordered
video slots. Every Storyboard slot must be ready before export.

**Output:** A saved merged video asset with preview/download. The Merge Video
node has no downstream output handle; use the saved video through your library
for another workflow.

**Try it:** Connect two compatible harbor clips, select Merge Video, arrange
the sequence, preview it, then choose **Export video**.

**Remember:** Export joins compatible clips in your browser. Clips need
matching video configuration, dimensions/orientation and audio layout. Supported
inputs are H.264 MP4 with compatible AAC audio, or compatible silent clips.
It does not convert mismatched clips or add transitions/background music.
