Stage definitions
A YAML manifest describes production steps, the tools involved and the conditions to check before moving on.
OpenMontage
OpenMontage gives a coding agent production plans and tools for moving a video from brief to rendered cut, with review points for footage, audio and captions.
Plan a product demo from an existing screen recording
Use OpenMontage’s staged production workflow to plan a short demo around the actions your viewer needs to see. Keep the footage, caption plan and final checks traceable.
List the source recording, essential actions, duration, audience and output aspect ratio.

Reference: OpenMontage https://github.com/calesthio/OpenMontage Read the original documentation and check the current environment and dependencies. Propose any new installation or tool connection before proceeding. My task: Review the OpenMontage repository and help plan a 45-second demo from my existing screen recording. Keep onboarding, search and the export confirmation visible. Propose a timestamped edit, flag caption overlaps and list checks for the 9:16 export. Ask before sending footage to an external service. Expected deliverable: An edit brief with timestamped scene choices, caption notes and a pre-delivery checklist.
How OpenMontage stages a video production
A product demo needs a script, screen recordings, captions and a final cut. OpenMontage breaks that work into stages with YAML pipeline definitions and separate instructions for the coding agent. The agent reads the plan, calls the relevant tools and records decisions and progress so later steps can use the same production context.
Different projects take different paths. An explainer may use generated stills and a Remotion composition, while a documentary montage can retrieve real motion clips from open archives and use them to assemble a timeline. The available providers, credentials and asset rights determine which path you can take.
For a Floatboat workflow, use the project as a reference for sequencing a brief, asset approval and cut review. Keep the intended delivery format visible from the beginning, then inspect sampled frames, captions and audio against that brief after rendering.
The production decisions OpenMontage makes visible
The pipeline leaves a record of which tools and assets were selected and when a result was checked. Use it to review choices that affect the finished cut, such as the footage source and composition engine.
Asset and provider selection
The agent can use source footage, local tools or configured cloud services, with selection rules that account for fit and cost.
Checks on the rendered cut
The project uses tools such as ffprobe, sampled frames and audio analysis to flag technical issues for review.
OpenMontage use cases
Pick the output first, from a real-footage montage to a captioned demo. Then choose the stages and inspection points that protect what the audience needs to see or hear.
Edit a short product demonstration
Start with a screen recording and a list of actions the viewer must see. Use the pipeline to draft the cut and captions, then verify that captions stay clear of controls and the edit preserves each essential step.
Build a montage from real motion clips
Specify real footage and a theme before sourcing. Track the origin and usage conditions of each candidate, then review whether the cut combines actual moving clips at the intended pace.
Create an animated explainer with a voice track
Approve the script and scene plan before producing visual assets. Render a short sample and listen for awkward pronunciations, then verify that scene changes still line up with narration after any revisions.
Prepare a localized version of a finished video
Retain the source transcript and use it to review the translated script before producing a new voice track. Check subtitle wrapping and time alignment in the localized render, especially around rapid speech or labels.
What to prepare for the source workflow
The upstream quick start runs inside a coding-agent workspace. Prepare the runtime and approved inputs before selecting a pipeline, and enable provider credentials only for services your production needs.
Project runtime
The source quick start lists Python 3.10+, Node.js 18+, FFmpeg and an AI coding assistant.
Material and delivery brief
Gather approved footage or source links, and specify duration, aspect ratio, audience and the expected output format.
Provider access
Some paths use local tools and open sources. Configured cloud models and some stock services require separate credentials and may incur charges.

OpenMontage FAQ
What runs the pipeline stages?
The coding assistant reads the stage definitions and calls the project tools. Its workspace and execution permissions govern what it can do.
Can OpenMontage use real motion clips?
Yes. Its documentary montage path can search a collection of open archival footage and cut selected clips into a timeline. Review the rights of each asset you use.
Do I need paid video generation to make a montage?
The repository describes a path using real footage from open sources and local processing. Other providers have their own credentials, terms and costs.
How does the project review a final render?
It documents technical checks such as probing the media file, sampling frames and analyzing audio. Review editorial intent, rights and accuracy before releasing the cut.
Is OpenMontage Studio the same thing as the repository?
The public repository documents the source workflow for a coding assistant. The website describes Studio as a Windows desktop app in private alpha.
What does the AGPL cover?
The repository lists GNU AGPL v3 for the source. Footage, fonts and third-party services may have separate terms that need checking for your production.
