OpenMontage

What it does

An agentic video production system: hand it footage, or paste a reference video to imitate, and the pipeline handles cutting, sequencing and captioning as directed rather than asking you to drive a timeline. Pipelines chain multiple steps and can be pointed at different providers for generation and analysis. Costs scale with runtime, so test on short clips before committing a long edit, and think about rights on any reference material you feed in. FFmpeg required. AGPL-3.0.

OpenMontage FAQ

Is OpenMontage free?

OpenMontage itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.

Do I need to install anything or write code to use OpenMontage?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does OpenMontage work on a phone?

No. It needs a computer.

Can I use OpenMontage commercially?

The licence is AGPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
