OpenMontage: an open-source tool that builds Opus videos from a reference clip
Arguing that Opus videos all look alike because no reference is given, the author uses OpenMontage to paste a liked video so Opus scripts, voices and renders scene by scene.
The Opus videos everyone's posting all look alike because nobody gives Opus anything to copy with no reference it falls back to centered text, gradients and fade-ins. the article above says it too OpenMontage flips that. you paste a video you like and Opus builds from it. open source, 64K stars, runs in Claude Code, Cursor or Codex I fed it a 20-second launch video I'd saved. before anything rendered I had 3 concepts, the API cost of each and a sample to approve it scripts, voices and renders scene by scene and waits for my yes before every step. their own 60-second animated short cost $1.33 to make the voice was the weakest part, but the motion beat everything I'd ever prompted by hand the reference video is the new prompt
