How to Merge Video Segments with Claude

Merge video segments using Claude and ToolRouter. Combine clips into polished videos with AI.

Tool
Video Editor icon
Video Editor

Claude assembles multi-segment videos through conversational editing in your terminal. Specify your clip order, define transition types between each pair, and finalize the output through iterative dialogue. Claude handles audio normalization and transition timing as part of the conversation, producing polished merged videos without timeline-based editing.

Steps

Once connected (see setup above), use the Video Editor tool:

  1. Provide your clips: "Merge these 4 video clips in order: intro.mp4, demo.mp4, testimonial.mp4, outro.mp4"
  2. Claude calls edit_footage to assemble the clips with transitions
  3. Add polish: "Add a 1-second crossfade between each segment"
  4. Finalize: "Run finalize_video to export the merged video at 1080p"

Example Prompt

Try this with Claude using the Video Editor tool
Merge these video clips into one video: intro (5s), product-demo (2min), customer-testimonial (45s), and CTA-outro (10s). Add 0.5-second crossfade transitions between each. Export at 1080p.

Tips

  • Specify transition types between each pair of clips for a polished result
  • Ask Claude to normalize audio levels across clips before merging
  • Use finalize_video at the end to ensure proper encoding and quality
