HeyGen adds cinematic avatar shots using its own video model
HeyGen’s November developer changelog adds cinematic avatar rendering through POST /v3/videos with model heygen_video_1. The current guide supports one to three avatar looks, optional references, 720p, 5–15 second shots and a linked voice for each look. HeyGen lists Cinematic Avatars as a Pro-plan feature; exact API entitlement and credit cost should be checked before production use. Its guide also offers Seedance 2 as an alternative model, which is not a HeyGen-trained model. The changelog gives November but no reliable day, so the story remains undated.
