Features
The only animation converter with a built-in music library
AI voiceover — 14 voices, local
Type a script and Kokoro TTS narrates your animation in one of 14 English voices. Runs entirely on-server — never sent to ElevenLabs or OpenAI. When voiceover and music are both present, FFmpeg auto-ducks the music during speech.
AI captions from Whisper
Local Whisper (small.en) transcribes any spoken audio and burns time-synced captions directly into frames. Four caption styles. No per-video charge — included in the $5/month flat rate.
500,000 CC0 tracks, any genre
Search Freesound's full CC0 catalog from inside Animation Machine — cinematic, lo-fi, corporate, ambient, upbeat. Music auto-loops or trims to match your animation's exact duration. No attribution required.
Volume control + auto-ducking
Set music volume 0–200%. Default is 10% for subtle background. Add voiceover and FFmpeg's sidechain compressor drops music ~8 dB during speech — voice on top, track underneath, like a podcast or radio ad.
FAQ
Animation with Background Music — Common Questions
What is CC0 music?
CC0 (Creative Commons Zero) means the creator has waived all copyright. You can use CC0 music in any video — personal, commercial, social media — without attribution or licensing fees.
Can I use the music commercially?
Yes. Every track in the library is CC0 licensed. Use them in client work, social media ads, product demos, or any commercial project without licensing fees or attribution requirements.
How is the music synced to the animation?
Animation Machine automatically loops or trims the music to match your animation's exact duration. If your animation is 15 seconds and the track is 3 minutes, only the first 15 seconds of the track play. Short tracks loop seamlessly to fill longer animations.
Can I upload my own audio?
Yes. Click the music panel and switch to the Upload tab. Drag in an MP3, WAV, M4A, AAC, or FLAC file. It syncs to your animation the same way as a searched track.
Does music work with GIF export?
No — GIFs don't support audio. Background music only applies to MP4 exports. If you choose GIF format, the music settings are ignored and the GIF exports silently.
Can I preview a track before using it?
Yes. Every search result has a play button so you can preview the track before selecting it. Click the preview button to listen, then click Use to add it to your render.
How many tracks are in the library?
Over 500,000 CC0 tracks in our built-in library, covering every genre: cinematic, lo-fi, corporate, ambient, upbeat, electronic, acoustic, and more. Search by mood, instrument, or style.
