Describe an idea and get a full scenario — concept, treatment and scene-by-scene structure — laid onto a multi-track timeline. Then refine it by asking, automate the repetitive work, and export. [Screenshot: Scene Flow Shop's editor: a five-scene timeline with video, voice, music and SFX tracks, and the AI assistant proposing to attach a background music prompt] The assistant proposes an exact change — here, attaching a music prompt to the score — and applies it once you approve. Every edit shown is a real, undoable operation on the same timeline you see. ### What is Scene Flow Shop? Scene Flow Shop is an AI video editor and scenario maker that runs in your browser. It pairs a multi-track timeline editor with an AI assistant that can plan a film from a single idea and then edit it for you. The assistant works through 53 Model Context Protocol (MCP) tools — the same operations you can perform by hand — so every change is visible, reviewable and undoable. There is no hidden AI-only path into your project. Scene Flow Shop plans, structures and edits. It does not generate video itself: bring footage from your camera, stock libraries or any AI video generator, and drop it onto the placeholders your scenario creates. ### Everything for AI-assisted video editing - **AI assistant for video editing**: Ask in plain language: trim this, move that, add crossfades everywhere. The assistant proposes exact changes and you approve them — or switch on auto mode. - **AI scenario maker**: Turn a one-line idea or a reference image into a concept, treatment and scene breakdown, then apply it straight to the timeline. - **Multi-track timeline**: Video and audio tracks, split, trim, duplicate, clip speed from −80% to +80%, per-clip and per-track volume, fades and crossfade transitions. - **Scene-by-scene prompts**: Draft five prompt variants for each shot — Balanced, More Cinematic, More Realistic, More Surreal, More Minimal — with revision history. - **53 MCP tools**: Projects, tracks, scenes, timeline edits, scenarios, prompts and rendering are all exposed as Model Context Protocol tools. - **Editing automation**: Batch dozens of edits into one approval and one undo, apply transitions across a whole track, or let auto mode build a rough cut unattended. - **1080p export**: Render a fast half-resolution preview or a full 1080p MP4 on a background worker while you keep editing. - **Undo history**: Every operation — yours or the assistant's — is versioned and attributed, and the most recent one can be undone. ### How it works: from idea to exported video 1. **Describe your idea**: Type a line or attach a reference image. The assistant reads its style, mood and environment. 2. **Generate the scenario**: Get a concept, treatment and scene-by-scene structure with narrative purpose and planned durations. 3. **Apply it to the timeline**: Each scene becomes placeholders on video, music and sound-effects tracks, with prompt slots attached. 4. **Fill in and refine**: Upload footage to replace placeholders, polish the prompts, and ask the assistant for trims, transitions, speed and volume changes. 5. **Automate the repetitive parts**: Use batch edits, bulk transitions and auto mode instead of clicking through every clip. 6. **Export**: Render a preview or a 1080p MP4 and download it. ### Built for filmmakers, creators and AI video workflows - **Short films and narrative video**: Get a structured scenario and a timeline skeleton before you shoot or generate a single clip. - **YouTube and social video**: Plan the story beats, pacing and durations, then assemble and tighten the cut faster. - **Ads, explainers and trailers**: Turn a brief into scenes with clear purposes, then iterate on timing and transitions. - **AI-generated footage**: Use the per-scene prompt variants with your favourite generation tool, then bring the clips back to edit. ### Pricing in one paragraph New accounts start with 20 free credits. Editing by hand costs nothing; credits pay for AI assistant usage and renders. Credit packs start at $5 for 100 credits, and you can bring your own Anthropic API key to use the assistant for free. See the pricing page for details. ### Frequently asked questions **What is Scene Flow Shop?** Scene Flow Shop is a browser-based AI video editor and scenario maker. It combines a multi-track timeline with an AI assistant that can plan a film from one idea and edit it through MCP tools. **Is Scene Flow Shop a text-to-video generator?** No. It plans, structures and edits video: scenarios, scenes, prompts and the timeline. Bring footage from a camera, stock library or any AI video generator and place it on the timeline. The prompt variants it drafts are written to be pasted into external generation tools. **How does the AI assistant edit my video?** The assistant calls editing tools — trim, split, move, speed, volume, transitions and more. By default it proposes the exact tool calls and you press Apply or Cancel. In auto mode it applies them itself. Every change is versioned and can be undone. **What is the scenario maker?** It turns an idea (or a reference image) into a concept with genre, tone, duration, logline and visual direction, plus scene drafts with titles, summaries, narrative purpose and planned durations. One step then lays the scenes onto the timeline as placeholders. **What are MCP tools and why do they matter?** The Model Context Protocol (MCP) is an open standard for giving AI models tools. Scene Flow Shop exposes 53 MCP tools covering the whole editor, so the assistant edits exactly the way you do, with the same validation, versioning and undo. **Can I automate video editing?** Yes. Auto mode lets the assistant carry out a multi-step build without waiting for approval, batch edits combine many timeline changes into one approval and one undo, and bulk operations apply transitions or close gaps across a whole track. **How much does it cost?** New accounts get 20 free credits. Credit packs are 100 for $5, 300 for $12, 1000 for $30. Manual editing is free; credits are spent on AI usage and renders. There is no subscription. **Which AI model powers the assistant?** The assistant uses Claude models from Anthropic. You can pick a model in Settings and, if you prefer, use your own Anthropic API key so the assistant costs you no credits. **What can I export?** You can render a half-resolution preview for quick review or a final MP4 at up to 1920×1080. ## AI video editor: edit your timeline by asking URL: https://www.sceneflow.shop/ai-video-editor Scene Flow Shop pairs a real multi-track timeline with an AI assistant that edits through the same tools you use. Say what you want — the assistant proposes exact changes, you approve them, and everything stays undoable. ### How AI video editing works here You chat with the assistant inside the editor. It reads a summary of your project — tracks, clips, durations, scenes and prompts — and answers with concrete edits rather than vague advice. Edits are proposed as tool calls. You see exactly what will change and press Apply or Cancel. Prefer to hand over the wheel? Switch on auto mode and the assistant carries out a multi-step build on its own. Every applied change is versioned and attributed to you or to the assistant, and the most recent operation can always be undone. ### What the assistant can edit - **Trim and split**: Cut clips to length or split them at a point on the timeline. - **Move and duplicate**: Reposition clips, reorder them, or duplicate a clip. - **Speed**: Change clip speed anywhere from −80% to +80%. - **Volume**: Set volume per clip or per track. - **Transitions**: Add crossfade, smooth blend, fade from black or fade to black, and adjust their duration. - **Close gaps**: Remove dead space between clips on a track, one gap or all of them. - **Batch edits**: Combine many edits into one call: one approval, one undo step. - **Tracks and scenes**: Create, rename, reorder and delete tracks and scenes. ### Manual control when you want it The assistant is optional. The editor stands on its own. - **Multi-track timeline**: Video and audio tracks with drag-to-move, trimming, splitting and zoom. - **Preview player**: Scrub and play the timeline in the browser; Space toggles play and pause. - **Fades and volume**: Editable fade durations and per-track volume. - **Export**: Render a preview or a 1080p MP4 on a background worker. ### Things you can ask “Add a crossfade between every clip on the video track.” “Close all the gaps.” “Slow the second clip down by 30%.” “Lower the music track volume.” “Split this clip at the 12-second mark.” “Build a first cut from this scenario.” ### Frequently asked questions **Does the AI change my project without asking?** Not by default. The assistant proposes the exact tool calls and waits for you to apply them. Only if you enable auto mode does it apply its own edits, and even then each one is versioned and undoable. **Does the assistant watch my footage?** No. It works from your project's structure — tracks, clip positions and durations, scenes and prompts — not from the pixels of your footage. Reference images you attach in chat are sent to the model so it can describe their style. **Which AI powers the assistant?** Claude models from Anthropic. Choose a model in Settings, and optionally add your own Anthropic API key so assistant messages don't use credits. **Is this a full replacement for a desktop editor?** It is a focused timeline editor for assembling, timing and transitioning clips — cuts, trims, speed, volume, fades and crossfades. It is not a colour-grading or visual-effects suite. **Can I undo what the assistant did?** Yes. Every operation is recorded, and the most recent one can be undone — whether you or the assistant made it. ## AI scenario maker: full scenario creation, end to end URL: https://www.sceneflow.shop/ai-scenario-maker Start with a sentence or a reference image and end with a structured scenario already sitting on your timeline. Scene Flow Shop carries the same project from concept to treatment to scenes to cut — no copy-pasting between a writing tool and an editor. ### From idea to scenario in one workflow 1. **Idea or reference image**: Describe the film in a line, or attach an image. The assistant reads its medium, style, lighting, mood and environment. 2. **Concept**: Genre, tone, target duration, logline, visual direction and an overall music direction. 3. **Treatment**: An optional written treatment that expands the concept into the story you'll tell. 4. **Scene breakdown**: Each scene gets a title, summary, narrative purpose and planned duration, plus video, sound and voice prompt drafts. 5. **Apply to the timeline**: One step creates the scenes and lays placeholders onto video, music and sound-effects tracks, with prompt slots ready. 6. **Iterate**: Revise the scenario or individual scenes, and keep refining with the assistant. ### Scenario, treatment, storyboard, shot list: what you get People call it a scenario, a script outline, a treatment, a storyboard or a shot list. Scene Flow Shop produces the structural layer all of those grow from: a concept, a treatment and an ordered set of scenes with purpose and timing. Because the scenario lives in the same project as the timeline, changing a scene's duration or purpose is an edit, not an export-and-reimport. ### Per-scene prompts for AI video and image tools Every scene can carry prompts for video, sound, music and voice. - **Five variants per prompt**: Balanced, More Cinematic, More Realistic, More Surreal and More Minimal, so you can pick a direction and edit it. - **Structured fields**: Style, camera, lighting, motion, environment and sound-design tags alongside the prompt text. - **Revision history**: Every prompt edit is a revision you can review; nothing is silently overwritten. - **Tool-agnostic**: Variants are written to stand alone, so you can paste them into any external generation tool. ### Then cut it in the same tool Upload or generate the footage elsewhere, drop it onto the placeholders, and edit on the timeline. The assistant can help with trims, transitions, speed and volume as you go. ### Frequently asked questions **Is this a screenplay generator?** It generates a scenario: concept, treatment and a scene-by-scene structure with narrative purpose and durations. That's the framework a screenplay grows from. You can ask the assistant to expand any scene in chat. **Can I edit the scenario after it's generated?** Yes. Scenarios and scenes are editable, and the assistant can revise them on request. Changes go through the same versioned, undoable tools as timeline edits. **Does it create the video too?** No. It creates the scenario, the timeline structure and the prompts. You supply the footage — filmed, stock or generated elsewhere — and replace the placeholders. **Can I start from an image?** Yes. Attach a reference image and the assistant describes its style and environment, then builds those details into the scenario and the scene prompts so shots stay visually consistent. **How long can the film be?** You set a target duration in the concept and a planned duration per scene; the timeline follows from those and you can adjust any of them. ## MCP video editor: 53 tools for AI-driven editing URL: https://www.sceneflow.shop/mcp-video-editing Scene Flow Shop is built on the Model Context Protocol. Creating a scenario, splitting a clip, adding a crossfade, starting a render: each is an MCP tool, and the built-in assistant edits only through them. ### Why MCP matters for video editing The Model Context Protocol is an open standard that lets AI models call tools in a structured, typed way. Instead of a chatbot describing what you should do, an MCP-native editor lets the model do it — through the same validated operations a person would use. In Scene Flow Shop the user interface, the REST API and the MCP server are thin adapters over one command layer. There is no AI-only backdoor: every mutation is version-checked, attributed to the user or the assistant, and undoable. Today these tools power the built-in assistant. The server speaks standard MCP over stdio. Hosted access for third-party MCP clients is not offered yet. ### All 53 MCP tools Read-only tools run immediately; anything that changes the project is proposed for your approval unless auto mode is on. - **Projects** (8): `project.create`, `project.list_for_owner`, `project.update`, `project.delete`, `project.get_state`, `project.get_summary`, `project.export`, `project.import` - **Tracks** (4): `track.create`, `track.update`, `track.delete`, `track.reorder` - **Scenes** (4): `scene.create`, `scene.update`, `scene.reorder`, `scene.delete` - **Timeline** (16): `timeline.add_placeholder`, `timeline.move_item`, `timeline.duplicate_item`, `timeline.trim_item`, `timeline.set_speed`, `timeline.set_volume`, `timeline.split_item`, `timeline.delete_item`, `timeline.close_gap`, `timeline.close_gaps`, `timeline.batch`, `timeline.add_transition`, `timeline.add_transitions`, `timeline.remove_transition`, `timeline.remove_transitions`, `timeline.update_transition_duration` - **Assets** (3): `asset.replace_placeholder`, `asset.get`, `asset.list` - **Scenarios** (5): `scenario.create`, `scenario.get`, `scenario.update`, `scenario.delete`, `scenario.apply_to_timeline` - **Prompts** (5): `prompt.attach`, `prompt.update`, `prompt.get`, `prompt.list_for_scene`, `prompt.list_revisions` - **Rendering** (6): `render.preview`, `render.final`, `render.status`, `render.get_result`, `render.list_for_project`, `render.delete` - **History & credits** (2): `project.undo`, `credits.get_balance` ### What an MCP-native editor gives you - **Safe autonomy**: Reads happen instantly; edits are proposed as exact tool calls you can approve, reject or auto-apply. - **Version-checked edits**: Each edit names the project version it expects, so a stale change is rejected instead of overwriting newer work. - **Batching**: timeline.batch groups many edits into one call, one approval and one undo step. - **Full-lifecycle coverage**: Idea, scenario, scenes, prompts, timeline, transitions, rendering and undo: the whole workflow is reachable by tools. - **One command layer**: UI, REST and MCP share the same operations, so behaviour never diverges between them. - **Auditable history**: Every operation records who made it: a user, the assistant or an external agent. ### Frequently asked questions **What is the Model Context Protocol (MCP)?** MCP is an open standard for connecting AI models to tools and data. A model discovers the available tools, calls them with structured arguments and receives structured results. **How many MCP tools does Scene Flow Shop have?** 53, across projects, tracks, scenes, timeline editing, assets, scenarios, prompts, rendering, undo and credits. **Can I use these tools from my own MCP client?** The tool surface is a standard MCP server, designed for that. At the moment it powers the built-in assistant; hosted access with per-user credentials for external clients isn't offered yet. **Are MCP edits safe?** Yes. Edits are validated, version-checked and recorded, the assistant asks for approval by default, and the latest operation can be undone. **Which model uses the tools?** The built-in assistant uses Claude models from Anthropic. ## Video editing automation, from batch edits to auto-build URL: https://www.sceneflow.shop/video-editing-automation Repetitive editing is where time disappears. Scene Flow Shop automates it with batch operations, bulk transitions, an auto mode that builds a rough cut unattended, and a render queue that works in the background. ### Automation you can use today - **Auto mode**: The assistant applies its own proposed edits without waiting for approval, carrying out a multi-step build such as scenario → timeline → prompts → transitions in a single request. - **Batch edits**: Trims, moves, speed and volume changes, transitions and gap closing combine into one call: one approval, one undo step. - **Bulk operations**: Add crossfades between every pair of adjacent clips, remove all transitions, or close every gap on a track in one command. - **Scenario to timeline**: One step turns an approved scenario into scenes, tracks and placeholders. - **Projects as templates**: Export a project as a file and import it as a starting point for the next one. - **Background rendering**: Preview and final renders run on a worker queue while you keep editing; failed renders are refunded. ### Automation with guardrails Approval is the default. The assistant proposes exact tool calls and you decide, so automation is something you turn on rather than something that happens to you. Even in auto mode every edit is version-checked, recorded with who made it, and undoable. If your credit balance runs out mid-build, the assistant stops cleanly instead of failing halfway. ### Example: idea to rough cut 1. **Describe the film**: One message with the idea, the tone and the target length. 2. **Turn on auto mode**: The assistant creates the scenario and applies it to the timeline. 3. **Bulk-polish**: Ask for crossfades across the video track and gaps closed, each in one batch. 4. **Review and export**: Undo anything you don't like, then render a preview. ### Where MCP fits in Because every operation is one of 53 MCP tools, the same building blocks that power auto mode are the foundation for wider automation. Read more on the MCP tools page. ### Frequently asked questions **Does auto mode ask permission for each edit?** No, that's the point of auto mode. You give one instruction and the assistant carries it out. Everything remains versioned and undoable, and approval-first mode is the default. **Can I trigger automations from my own scripts?** There's no public API or scheduler today. Automation currently happens through the assistant, batch and bulk operations, and auto mode. The MCP tool surface is the foundation for external automation. **What happens if I run out of credits during auto mode?** The assistant stops and tells you. Edits already made stay in place and can be undone; buy credits or use your own Anthropic key to continue. **Can I reuse a project's structure?** Yes. Export a project to a file and import it to start a new one from the same tracks, scenes and timeline. ## Pricing: pay for AI and renders, not for editing URL: https://www.sceneflow.shop/pricing Every new account starts with 20 free credits.
