Describe the video you want. Your coding agent creates the scenes, places the motion graphics, and syncs the music. Every layer lands on the timeline. Then tweak anything by hand and export.

$npx -y agentcut

First, install Node.js LTS (20.10 or newer) and reopen your terminal. The command downloads and starts Agentcut automatically.

Make a 17 second launch reel: a cinematic opener on the mountains, my talking-head clip with captions, end on the logo. LFG.

Read brief.md and the clip's transcript

Opened on mountains-hd.jpg with a title

Captioned the talking head word by word

Placed lower third, sticker and end card

Checked 6 frames, wide and mobile

Done: 17 seconds, 7 tracks. The captions follow your voice word by word, and the “100% open source” sticker lands on the line.
