HeyGen Cinematic Avatar API
Prompt-driven cinematic shots featuring your avatar — describe a scene (camera, setting, action) and HeyGen renders a documentary-style clip from 1–3 avatar looks, optionally guided by reference clips/images.
$0.105/s on Varosity credits ($0.100/s with your own key). Clips up to 15s with native audio.
no heygen account needed · no subscription · failed renders never billed
Best for
- prompt-driven cinematic shots
- blends 1–3 avatar looks into a scene
- reference videos/images for style
Trade-offs
- 4–15s per clip
- less control than a scripted avatar video
Call it from your code
One Varosity key works for every model. Video renders are async — the response has a jobId; poll GET /api/v1/jobs/{jobId} until status is "succeeded", then read outputUrl.
