FilmMovie Studio tutorials
Hands-on, step-by-step guides: what to open, where to click and what to type to turn a single idea into a finished video, game, app or product shot — right inside FilmMovie Studio.
/beat-sync-editorCut to the beat: land every edit exactly on the music
Turn clips and images into a music video where every cut lands exactly on a beat. Let the app detect the rhythm grid, plan a cut list and assemble a montage on a timeline with beat markers.
/narrate-sceneAdd a spoken voiceover: one shot and a voice that narrates it
With /narrate-scene you turn a silent shot into a narrated scene: pick a voice, paste your narration, the app generates the TTS voice and loops your picture or clip to exactly match the voice length — then assembles it on the timeline and renders.
/voice-designDesign a custom voice from a description — with no recording at all
With /voice-design you create a brand-new synthetic voice from a text description alone — age, tone, accent, pace. You preview a test line, save the voice on the canvas and reuse it across your narration.
/threejs-gameBuild a 3D browser game: Three.js, Rapier physics and a one-file HTML export
With /threejs-game you turn a sentence into a playable 3D game right on the canvas. The AI builds it piece by piece as self-contained HTML with a Three.js scene, Rapier physics and post-processing — you play it inline in the card, tune it via chat and finally export a single .html file.
/app-walkthroughRecord a narrated demo video that clicks through every screen of your app
Turn the app you assembled with /app-builder into a polished walkthrough video. /app-walkthrough records the live play-mode preview, an animated cursor taps through the navigation, a one-line voiceover is written for each screen and it renders a finished MP4 onto the canvas.
Build your own skill: from a workflow you liked to a custom SKILL.md
For power users: take a workflow you've dialed in and turn it into your own reusable skill with /skill-creator. The app scaffolds a complete SKILL.md against the tool catalog and walks you through installing it into the Hub, so you can later run it from your own slash command.
/skill-reviewerAudit your own skill: how /skill-reviewer scores and tightens your SKILL.md
For skill authors: paste your SKILL.md and /skill-reviewer scores it across five dimensions, flags critical bugs (like non-existent tools) and returns prioritized fixes on a canvas card — without touching your file.
