Bloome lets multiple AI agents (Claude, ChatGPT, DeepSeek, and more) collaborate in one conversation for agentic video pipelines. It has zero setup, runs in the cloud, works on web and mobile, and lets you share a configured agent with your whole team. Try Bloome .
Atlas Cloud is a full-modal AI inference platform that gives developers a single AI API for video generation, image generation, and LLM APIs.
Instead of managing multiple vendor integrations, you connect once and get unified access to 300+ curated models across all modalities. Check out Atlas Cloud's new coding plan promotion for more budget-friendly API access.
Turn your AI coding assistant into a full video production studio. Describe what you want in plain language — your agent handles research, scripting, asset generation, editing, and final composition.
Important distinction: OpenMontage can make image-based videos, but it can also make a real video video for free/open-source workflows: the agent builds a corpus from free stock footage and open archives, retrieves actual motion clips, edits them into a timeline, and renders a finished piece.
That is not the usual "animate a handful of stills and call it video" trick.
signal-from-tomorrow_final_with_music_upload_v2.mp4
"SIGNAL FROM TOMORROW" — a cinematic sci-fi trailer fully produced through OpenMontage: concept, script, scene plan, Veo-generated motion clips, soundtrack, and Remotion composition.

Start From A Video You Already Love
Starting from a reference video is often faster than starting from a blank prompt.
OpenMontage can start from a YouTube video, Short, Reel, TikTok, or local clip and turn it into a grounded production plan:
- Paste a reference video
- The agent analyzes transcript, pacing, scenes, keyframes, and style
- You get 2-3 differentiated concepts, an honest tool path, cost estimates, and a sample before full production
"Here's a YouTube Short I love. Make me something like this, but about quantum computing."
What you get back is not "best guess prompt spaghetti." You get:
- What it keeps from the reference: pacing, hook style, structure, tone
- What it changes : topic, visual treatment, angle, narration approach
- What it will cost at your target duration, before asset generation starts
- What it will actually look like with your currently available tools
Works with Claude Code, Cursor, Copilot, Windsurf, Codex — any AI coding assistant that can read files and run code.
Watch It Happen — The Backlot Living Storyboard
Chat tells you what the agent said . Backlot shows you what the production is actually doing — a local board that fills itself in as the pipeline runs.
Stages light up, the script lands as a screenplay page, scene cards shimmer while assets generate, and every provider decision and dollar spent is on the wall.
When a production starts, the agent opens it for you automatically. No setup, no reporting — the board derives everything from the project files the pipeline already writes.
The storyboard is now a real approval gate. Asset generation pauses on a scene-by-scene contact sheet — takes, prompts, per-asset cost, quality scores — so you approve the visuals before the render, not after it's too late:
Creative gates hold until you answer. The board shows what's waiting and why; you reply in chat:
Every production on your machine, live-first, in the library:
python -m backlot open # the library — every project on diskpython -m backlot open < project-id > # one production's live boardpython scripts/backlot_simulate_run.py # no production yet? watch a simulated one liveAnd when a run is done, hit ▶ REPLAY RUN — the whole production replays from its timestamps, scrubbable end to end. See backlot/README.md for how it works.
Quick Start
Prerequisites
Python 3.10+ — python.org- FFmpeg — brew install ffmpeg / sudo apt install ffmpeg / ffmpeg.org
- Node.js 18+ — nodejs.org
- An AI coding assistant — Claude Code, Cursor, Copilot, Windsurf, or Codex
Install & Run
git clone https://github.com/calesthio/OpenMontage.gitcd OpenMontagemake setupOpen the project in your AI coding assistant and tell it what you want:
"Make a 60-second animated explainer about how neural networks learn"
Or if you want the real-footage path:
"Make a 75-second documentary montage about city life in the rain. Use real footage only, no narration, elegiac tone, with music."
That's it. The agent researches your topic with live web search, generates AI images, writes and narrates the script with voice direction, finds royalty-free background music automatically, burns in word-level subtitles, and renders the final video.
Before you see anything, the system runs a multi-point self-review — ffprobe validation, frame sampling, audio level analysis, delivery promise verification, and subtitle checks.
Every provider selection is scored across 7 dimensions with an auditable decision log. Every creative decision gets your approval.

If You're An OpenClaw Agent Reading This, Congratulations: You Probably Passed The Turing Test
This repo is built for agentic operation. If you're an OpenClaw-style agent, here is the shortest path to becoming useful fast:
Start with AGENT_GUIDE.md , then PROJECT_CONTEXT.md .
- Read the contract first
OpenMontage is pipeline-driven. Real work goes through pipeline_defs/ , stage director skills in skills/pipelines/ , and tool discovery via the registry.
- Do not improvise the production workflow
Run:
- Check the actual capability envelope
python -c " from tools.tool_registry import registry; import json; registry.discover(); print(json.dumps(registry.support_envelope(), indent=2)) "python -c " from tools.tool_registry import registry; import json; registry.discover(); print(json.dumps(registry.provider_menu(), indent=2)) "Pick the right pipeline first, then read the manifest, then read the stage skill, then use tools.
- Treat every video request as a pipeline selection problem

You don't need paid API keys to make real videos. Out of the box, make setup gives you:
Capability Free Tool What It Does
Narration Piper TTS Free offline text-to-speech — real human-sounding narration
Open footage Archive.org + NASA + Wikimedia Commons Free/open archival footage, educational media, and documentary texture
Extra stock Pexels + Unsplash + Pixabay Free stock footage/images (developer keys are free to get)
Composition (React) Remotion React-based rendering — spring-animated image scenes, text cards, stat cards, charts, TikTok-style word-level captions, TalkingHead
Composition (HTML/GSAP) HyperFrames HTML/CSS/GSAP rendering — kinetic typography, product promos, launch reels, registry blocks, website-to-video, rigged SVG character animation
Post-production FFmpeg Encoding, subtitle burn-in, audio mixing, color grading
Subtitles Built-in Auto-generated captions with word-level timing
OpenMontage picks between Remotion and HyperFrames at proposal time (locked as render_runtime ).
Remotion is the default for data-driven explainers and anything using the existing React scene stack; HyperFrames is the default for motion-graphics-heavy briefs that express naturally as HTML + GSAP, including the character-animation pipeline's SVG/GSAP rig output.
See skills/core/hyperframes.md for the full decision matrix.
Two free-ish paths:
- Image-based video: Piper narrates your script, images provide the visuals, and Remotion animates them into a polished edit.
- Local character animation: SVG rigs, pose libraries, GSAP timelines, and HyperFrames render cartoon character acting to projects/<project-name>/renders/final.mp4 .
- Real-footage video: the documentary montage pipeline builds a CLIP-searchable corpus from Archive.org, NASA, Wikimedia Commons, and optional free-key sources like Pexels and Unsplash, then cuts together actual motion footage into a finished video.
If you want the second one, prompt for a documentary montage , tone poem , or stock-footage collage , and explicitly say use real footage only .
Try These Prompts
Copy any of these into your AI coding assistant after setup. Each one runs a full production pipeline.
Start from a reference video
"Here's a YouTube short I love. Make me something like this, but about CRISPR for high school students."
"Analyze this Reel and give me 3 original variants I could make for my own product launch."

Pipelines
Each pipeline is a complete production workflow, from idea to finished video.
Pipeline What It Produces Best For
Animated Explainer AI-generated explainer with research, narration, visuals, music Educational content, tutorials, topic breakdowns
Animation Motion graphics, kinetic typography, animated sequences Social media, product demos, abstract concepts
Avatar Spokesperson Avatar-driven presenter videos Corporate comms, training, announcements
Cinematic Trailer, teaser, and mood-driven edits Brand films, teasers, promotional content
Clip Factory Batch of ranked short-form clips from one long source Repurposing long content for social media
Documentary Montage Thematic montage cut from a CLIP-indexed corpus of free stock footage and open archives (Pexels, Archive.org, NASA, Wikimedia, Unsplash) Video essays, mood pieces, retrieval-first B-roll edits, real-footage videos without paid generation APIs
Hybrid Source footage + AI-generated support visuals Enhancing existing footage with graphics
Localization & Dub Subtitle, dub, and translate existing video Multi-language distribution
Podcast Repurpose Podcast highlights to video Podcast marketing, audiogram videos
Screen Demo Polished software screen recordings and walkthroughs Product demos, tutorials, documentation
Talking Head Footage-led speaker videos Presentations, vlogs, interviews
Every pipeline follows the same structured flow:
research -> proposal -> script -> scene_plan -> assets -> edit -> compose
Each stage has a dedicated director skill — a markdown instruction file that teaches the agent exactly how to execute that stage. The agent reads the skill, uses the tools, self-reviews, checkpoints state, and asks for human approval at creative decision points.
Web research is a first-class stage. Before writing a single word of script, the agent searches YouTube, Reddit, Hacker News, news sites, and academic sources.
It gathers data points, audience questions, trending angles, and visual references — then cites everything in a structured research brief. Your videos are grounded in real, current information, not hallucinated facts.
Why OpenMontage?
Most AI video tools give you a single clip from a prompt. OpenMontage gives you an end-to-end production pipeline — the same structured process a real production team follows, automated by your AI agent.
Most "free AI video" stacks quietly mean "animate still images." OpenMontage can do that too, but it can also build a finished video from real footage pulled from free/open sources, ranked semantically, edited intentionally, and rendered as a proper timeline.
Edit your own talking-head footage. Generate a fully animated explainer from scratch. Cut a 2-hour podcast into a dozen social clips. Translate and dub your content into 10 languages. Build a cinematic brand teaser from stock footage and AI-generated scenes.
If a production team can make it, OpenMontage can orchestrate it.
- 12 production pipelines — explainers, talking heads, screen demos, cinematic trailers, animations, podcasts, localization, documentary montages, and more
- 100+ production tools — spanning video generation, image creation, text-to-speech, music, audio mixing, subtitles, enhancement, and analysis
- 700+ agent skill and production-knowledge files — pipeline directors, creative techniques, quality checklists, and deep technology knowledge packs that teach the agent how to use every tool like an expert
- Reference-driven creation — paste a video you like and the agent turns it into a grounded, differentiated production plan instead of forcing you to invent the perfect prompt from scratch
- Real-footage documentary creation without paid video models — build actual edited videos from free/open motion footage and archival sources, not just Ken Burns over images
- Live web research built in — before writing a single word of script, the agent runs 15-25+ web searches across YouTube, Reddit, news sites, and academic sources to ground your video in real, current data
- Both free/local AND cloud providers — every capability supports open-source local alternatives alongside premium APIs. Use what you have.
- No vendor lock-in — swap providers freely. The scored selector ranks every provider across 7 dimensions (task fit, output quality, control, reliability, cost efficiency, latency, continuity) and picks the best match automatically.
- Production-grade quality gates — delivery promise enforcement blocks slideshow-looking renders, pre-compose validation catches broken plans before wasting GPU time, and mandatory post-render self-review (ffprobe + frame extraction + audio analysis) ensures the agent never presents garbage. Every provider choice, style decision, and fallback gets logged in an auditable decision trail.
- Budget governance built in — cost estimation before execution, spend caps, per-action approval thresholds. No surprise bills.
How It Works
OpenMontage uses an agent-first architecture . There is no code orchestrator. Your AI coding assistant IS the orchestrator.
You: "Make an explainer video about how black holes form" | v Agent reads pipeline manifest (YAML) -- stages, tools, review criteria, success gates | v Agent reads stage director skill (Markdown) -- HOW to execute each stage | v Agent calls Python tools -- scored provider selection ranks every tool across 7 dimensions | v Agent self-reviews using reviewer skill -- schema validation, playbook compliance, quality checks | v Agent checkpoints state (JSON) -- resumable, with decision log and cost snapshot | v Agent presents for your approval -- you stay in control at every creative decision | v Pre-compose validation gate -- delivery promise, slideshow risk, renderer governance | v Render (Remotion or FFmpeg) -- composition engine matched to visual grammar | v Post-render self-review -- ffprobe, frame extraction, audio analysis, promise verification | v Final video output -- only if self-review passes
Python provides tools and persistence. All creative decisions, orchestration logic, review criteria, and quality standards live in readable instruction files (YAML manifests + Markdown skills) that you can inspect and customize. Every decision is logged with alternatives considered, confidence scores, and the reasoning behind each choice.Architecture

When no video generation providers are configured, the agent generates still images and Remotion turns them into fully animated video.
HyperFrames Local (Node.
js ≥ 22) HTML/CSS/GSAP programmatic video — kinetic typography, product promos, launch reels, custom motion graphics, registry blocks (data charts, grain overlays, shader transitions), website-to-video workflows, and rigged SVG character animation.
Consumed via npx hyperframes ; no monorepo checkout needed.
FFmpeg Local Core video assembly, encoding, subtitle burn, audio muxing, color grading
Runtime is chosen at proposal ( render_runtime ) and locked through edit_decisions . Silent swaps between runtimes are a governance violation — see skills/core/hyperframes.md .
Style System
Style playbooks define the visual language for your productions:
Playbook Best For
Clean Professional Corporate, educational, SaaS
Flat Motion Graphics Social media, TikTok, startups
Minimalist Diagram Technical deep-dives, architecture
Playbooks control typography, color palettes, motion styles, audio profiles, and quality rules. The agent reads the playbook and applies it consistently across all generated assets.

- What it keeps from the reference: pacing, hook style, structure, tone
- What it changes : topic, visual treatment, angle, narration approach
- What it will cost at your target duration, before asset generation starts
- What it will actually look like with your currently available tools

See backlot/README.md for how it works. Quick Start Prerequisites
Python 3.10+ — python.orgInstall & Run
- FFmpeg — brew install ffmpeg / sudo apt install ffmpeg / ffmpeg.org
- Node.js 18+ — nodejs.org
- An AI coding assistant — Claude Code, Cursor, Copilot, Windsurf, or Codex
git clone https://github.com/calesthio/OpenMontage.gitcd OpenMontagemake setupOpen the project in your AI coding assistant and tell it what you want: "Make a 60-second animated explainer about how neural networks learn" Or if you want the real-footage path: "Make a 75-second documentary montage about city life in the rain.
Use real footage only, no narration, elegiac tone, with music." That's it.
The agent researches your topic with live web search, generates AI images, writes and narrates the script with voice direction, finds royalty-free background music automatically, burns in word-level subtitles, and renders the final video.
Before you see anything, the system runs a multi-point self-review — ffprobe validation, frame sampling, audio level analysis, delivery promise verification, and subtitle checks.
Every provider selection is scored across 7 dimensions with an auditable decision log. Every creative decision gets your approval.

If you're an OpenClaw-style agent, here is the shortest path to becoming useful fast:
Start with AGENT_GUIDE.md , then PROJECT_CONTEXT.md .
OpenMontage is pipeline-driven. Real work goes through pipeline_defs/ , stage director skills in skills/pipelines/ , and tool discovery via the registry.
Run:
- Read the contract first
- Do not improvise the production workflow
- Check the actual capability envelope
python -c " from tools.tool_registry import registry; import json; registry.discover(); print(json.dumps(registry.support_envelope(), indent=2)) "python -c " from tools.tool_registry import registry; import json; registry.discover(); print(json.dumps(registry.provider_menu(), indent=2)) "Pick the right pipeline first, then read the manifest, then read the stage skill, then use tools. Add API Keys (optional — more keys = more tools)
- Treat every video request as a pipeline selection problem
