digital-humanDigital Human turns a video of a person plus a driving audio clip into a lip-synced talking video: the person keeps their original look, motion and background while the mouth is re-animated to speak the audio. If the audio runs longer than the video, the footage is extended automatically — the output always follows the audio length. Send two URLs (video_url: mp4/mov of the person; audio_url: mp3/wav/m4a, up to 30 minutes) and get an mp4 back at the source video's resolution. Billing is $0.01 per second of the driving audio — a 60-second voiceover costs $0.60, half the per-second price of image-based lip-sync. Use AI Lip-Sync instead when you only have a still portrait image. Typical turnaround is about 2 minutes for short clips. Only successful generations are charged; results are kept for 7 days.
$0.01 per second of audio vs $0.02/s for the image-based ai-lipsync — when you already have footage of the person, this is the cheaper path
Lighting, motion, background and camera work come from your footage; only the mouth is re-animated to match the new audio
Audio longer than the video? The footage is extended automatically — verified with a 6.2s voiceover over a 5s clip
Output matches the source video resolution (tested at 1440×2560) — no forced downscale
POST /api/v1/video/generations with model digital-human, video_url and audio_url — poll the task id for the mp4
$0.01 per second of audio · if the audio outlasts the video, the footage is extended automatically
