Features
Everything you need for Anime.js to MP4
AI voiceover — 14 voices, local
Type a script and Kokoro TTS narrates your Anime.js in one of 14 English voices. Runs entirely on-server — your script never goes to ElevenLabs, OpenAI, or any external API. Auto-ducks under background music.
AI captions from Whisper
Local Whisper (small.en) transcribes any spoken audio and burns time-synced captions directly into frames. Four caption styles — from subtle lower-thirds to bold TikTok-ready text. No API costs, no audio uploads.
500,000 CC0 music tracks
Search Freesound's entire CC0 catalog from inside Animation Machine. Cinematic, lo-fi, ambient, upbeat — every genre. Music loops or trims to match your Anime.js's exact duration. No attribution required.
Frame-perfect timeline rendering
Your timeline is stepped at a synthetic clock — springs, easings, and staggered sequences come out exactly as designed, with no timing drift.
FAQ
Anime.js to MP4 — Common Questions
Can I export an Anime.js animation to MP4?
Yes — Animation Machine runs your Anime.js timeline in a full Chromium browser and captures it frame by frame. Easings, timelines, SVG morphs, and staggering all render exactly as they do in the browser.
How do I prepare my Anime.js project?
Zip your HTML together with the anime.js script (or use the CDN import inside a single HTML file) and upload. Timelines driven by requestAnimationFrame render naturally.
Will all Anime.js features render correctly?
Animation Machine renders your Anime.js animation in a full Chromium browser, so anything that displays correctly in a browser — including vector shapes, masks, effects, and image assets — will render correctly in the video.
What resolution and quality can I export?
Export at 1920×1080 (landscape), 1280×720 (720p), 1080×1920 (portrait), or 1080×1080 (square). Quality presets are Draft (fast), Standard, and High. Portrait and square use a crop-to-fill approach for clean output.
Can I add background music to my Anime.js video?
Yes. Search our 500,000-track CC0 music library or upload your own audio file. The music is automatically looped and trimmed to match your animation's exact duration.
Can I export a Anime.js animation as GIF instead of MP4?
Yes. Animation Machine supports both MP4 and animated GIF export. GIF works well for short loops that need to autoplay in emails or messaging apps; MP4 is better for longer animations or when file size matters.
How much does Animation Machine cost?
Animation Machine is $5 per month with unlimited renders. No per-export fees. Cancel anytime from your account settings.
