Features
Purpose-built for Claude Design
AI voiceover — 14 voices, local
Type a script and Kokoro TTS narrates your Claude Design animation in one of 14 English voices. Runs entirely on-server — your script never goes to ElevenLabs, OpenAI, or any external API. Auto-ducks under music.
AI captions from Whisper
Local Whisper (small.en) transcribes any spoken audio and burns time-synced captions into frames. Four styles — subtle lower-thirds to bold social-native text. No API costs, no audio leaves your render.
Purpose-built for Claude Design
Animation Machine injects its own RAF shim to step the animation frame-by-frame and automatically strips the PlaybackBar from exports — the only converter that handles both correctly. No configuration needed.
500,000 CC0 music tracks
Search Freesound's CC0 catalog from inside Animation Machine. Cinematic, lo-fi, ambient, upbeat — every genre. Music loops or trims to match your animation's exact duration. No attribution required.
FAQ
Claude Design to MP4 — Common Questions
What is Claude Design?
Claude Design is Anthropic's animation tool built into Claude. When you ask Claude to create an animation, it generates a self-contained HTML file with requestAnimationFrame-based animation code. These can be downloaded as ZIP files for use as-is in the browser, or converted to video with Animation Machine.
How is Animation Machine different from other converters for Claude Design?
Claude Design uses requestAnimationFrame with a synthetic clock — not a fixed-duration timeline. Most converters record screen output in real-time, producing timing drift. Animation Machine injects its own RAF shim to step the animation frame-by-frame, producing perfectly timed output regardless of rendering speed. No other converter does this.
Do I need to modify my Claude Design export before uploading?
No. Upload the ZIP exactly as Claude exports it. Animation Machine detects Claude Design automatically and handles everything — RAF shim injection, PlaybackBar removal, orientation detection. No modifications required.
What about the PlaybackBar scrubber at the bottom?
Claude Design exports include a scrubber/timeline bar at the bottom of the animation. Animation Machine automatically detects it and removes it from the video output. Your final file is clean — no scrubber visible.
What if my Claude Design ZIP has multiple HTML files?
Animation Machine will show you a file picker so you can choose which HTML file to render. This handles Claude Design exports that include multiple animation variants or scenes.
Can I add background music to my Claude Design video?
Yes. Search our 500,000-track CC0 music library or upload your own audio file. The music is looped and trimmed to match your animation's exact duration.
How much does Animation Machine cost?
Animation Machine is $5 per month — or $36 per year (save 40%) — with unlimited renders. No per-export fees. Cancel anytime from your account settings.
