AI Talking Head — FAQ
Upload a portrait photo + an audio clip (or speech file), AI animates the face to lip-sync the audio. Output is an MP4 video of the photo "speaking" the audio with realistic mouth movements, head sway, and blinks. Two models: free SadTalker (self-hosted, MIT) or premium lipsync (sharper mouth, faster).
Yes — SadTalker runs on our self-hosted GPUs, free in the daily token pool. Each clip costs ~6,000 tokens base + 800 tokens per second of audio. So a 10-second clip is ~14,000 tokens. Anonymous get 2,500/day, signed-in get 10,000/day. Premium scales by length too but with sharper output.
SadTalker (default) is free and produces a natural talking-head with subtle head motion + blinks. Premium lipsync has sharper mouth shapes (especially for plosives and bilabials like "p", "b", "m") and renders 2-3x faster on long audio. For social-media explainers and avatars, SadTalker is great. For high-fidelity dubbing and lip-sync-critical content, switch to premium.
Front-facing portrait, clear face, even lighting, neutral expression. The face should fill at least 30% of the frame. Avoid heavy sunglasses (they break eye tracking), profile shots (the model needs both eyes visible), and extreme expressions. Studio headshots and good selfies work great.
WAV or MP3 of clear speech. SadTalker handles 1-30 second clips reliably, longer is supported but slower. For best lip-sync, use a single speaker, low background noise, and clearly enunciated speech. Generate the audio first via /tts/ if you want to script the talking head.
SadTalker takes about 10 seconds of GPU time per second of audio. So a 10-second talking head takes ~100 seconds. Premium lipsync is faster (~3-5 seconds per second of audio) but costs more. Both run on our A100s — you can close the tab and the result lands in your dashboard.
D-ID charges $5.99/month for 5 minutes of video. HeyGen is $24/month. Synthesia is $30/month. We give you SadTalker free in the daily pool — comparable quality for explainer / avatar videos. Premium lipsync matches D-ID Studio quality. The free option is honestly good enough for most TikTok / YouTube short use cases.
Yes — generate a face via /image/avatar/ or /image/generate/, then feed it here. The model treats any front-facing portrait the same way. Common chain: prompt → SDXL portrait → SadTalker animates → /tts/ for the voice → done.
SadTalker animates the face region (mouth, eyes, head sway, blinks). The shoulders, clothing, and background stay nearly static. For full-body talking-head with body movement, use the premium lipsync model with a wider crop.
Yes — POST to /v1/video/talking-head/ with multipart `image` + `audio`. Or use /scheduled/ to queue many runs. /batch/ also accepts CSV of image-URL + audio-URL pairs.
Yes — POST multipart `image` + `audio` to /v1/video/talking-head/ on api.free.ai. Bearer auth. Returns JSON with `video_url` + `share_token`. 10,000 tokens/month free. Premium scales linearly with audio duration. /api/ has the curl example.
