HeyGen AI video generator: HeyGen Video 1 in full, narrated videos
HeyGen Video 1 is HeyGen’s generative video model: it creates 5 to 15-second clips at up to 768p from text or a starting image, with synchronized ambience and sound effects. It is also one of the most affordable models available, at about one credit per second.
In ShortsMachine, HeyGen Video 1 animates every scene of your script. Each clip starts from a key image so characters stay consistent, and the model’s own sound is mixed quietly under the narration and captions.

- Sound included: ambience and effects such as wind, waves or footsteps add atmosphere under your voiceover.
- Longer clips: up to 15 seconds per scene means fewer cuts in long videos.
- Available on every plan, starting with Starter.
What it costs
A finished minute on HeyGen Video 1 — including scene images and voiceover — uses roughly 70 credits. The Starter plan’s 200 monthly credits cover nearly three minutes, and Premium’s 2,000 credits cover over 25 minutes.

- Testing ideas cheaply before remaking the best ones on a premium model.
HeyGen Video 1 vs other models
Compared with Wan 2.2 Fast, HeyGen gives sharper 768p clips, longer shots and its own sound at a similar price. For smoother, more cinematic motion step up to Grok Imagine or FLUX 3 Max on Pro, or Kling 3.0 and Seedance on Premium. HeyGen Video 1 does not support the 1:1 square format, so use 9:16 or 16:9.
