Features
Everything you need for Jitter to MP4
AI voiceover — 14 voices, local
Type a script and Kokoro TTS narrates your Jitter 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 Jitter's exact duration. No attribution required.
Frame-perfect Lottie rendering
Your Jitter export runs as Lottie in a real Chromium browser, stepped frame-by-frame — vectors, masks, and effects render with no drift.
FAQ
Jitter to MP4 — Common Questions
How do I export a Jitter animation to MP4?
Export your animation from Jitter as a Lottie ZIP, then upload it to Animation Machine. It renders frame-perfectly in Chromium, with music, AI voiceover, captions, and intro/outro cards added in the same render.
Why not just use Jitter’s built-in video export?
Jitter’s export gives you the raw clip — Animation Machine adds the publishing layer: background music from 500k CC0 tracks, AI voiceover, auto-captions, branding, and platform-sized variants in one pass.
Will all Jitter features render correctly?
Animation Machine renders your Jitter 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 Jitter 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 Jitter 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.
