HeyGen Video 1 and MiniMax H3 are not two rivals. HeyGen Video 1 is a post-train of MiniMax H3, so it starts from the same model and is tuned by HeyGen for its own look and sound. MiniMax H3 is the open base, and Morphic runs it, along with Morphic H3, a variant with native audio. So the real question is what HeyGen added on top, and whether it is worth leaving a model you can run today. Here is how they line up.
HeyGen Video 1 vs MiniMax H3: the specs
Each maker's own published figures. MiniMax H3 is the base model; Morphic H3 is the native-audio variant Morphic runs.

The runnable one, with native audio
You cannot run HeyGen Video 1 on Morphic, but you can run the model it is built on, with audio. Morphic H3 writes the picture and a synced soundtrack in one pass, the same idea HeyGen Video 1 sells. Turn on sound to hear it.

Where HeyGen Video 1 differs
- A higher top resolution. HeyGen Video 1 renders up to 2K, where the base MiniMax H3 tops out at 1440p, so a finished clip can go a step sharper.
- HeyGen's own tuning. The post-train is shaped for HeyGen's look and audio, which is the point of a fine-tune: a particular feel on top of the base model's behavior.
- A reference-to-video mode. HeyGen exposes an image reference that the clip follows, useful when you want a specific subject or style carried through.
These are HeyGen's own claims, from the HeyGen Video 1 listing. Results vary by prompt, so weigh them against a model you can actually test.
Where MiniMax H3 wins
- You can run it today. MiniMax H3 and Morphic H3 are on the Morphic roster now. HeyGen Video 1 lives on HeyGen and a few model services.
- Native audio, cheaply. Morphic H3 generates a synced soundtrack with the video from 5 credits per second, so the one-pass idea costs very little on Morphic.
- In the whole workflow. On Morphic the clip lands on the Canvas, next to a timeline editor and the rest of the model roster, so you finish the video in one place instead of exporting from a single-model service.
Which should you use?
If you want HeyGen's specific tuning or its 2K output and you are already working inside HeyGen, HeyGen Video 1 is the fine-tune to reach for. If you want text-to-video with native audio that you can run today, keep, and finish in one workspace, MiniMax H3 on Morphic, in its Morphic H3 audio variant, does the same job from the same base model. For most people building videos end to end, the model you can run and edit in one place wins.
Run MiniMax H3 on Morphic
Morphic is a complete AI video workspace: a full model roster, AI storyboarding on a shared Canvas, and a built-in timeline editor, with Copilot running the work between them.
- One pass, with sound. Describe the scene and the sound, and Morphic H3 returns the picture and a synced soundtrack together.
- Finish in one place. Cut on the timeline, balance audio per clip, and add subtitles, with no export step.
MiniMax H3 and Morphic H3 are on the roster now.
FAQs
HeyGen Video 1 is a post-train of MiniMax H3, so it is built on that model rather than being a separate one. HeyGen tuned it for its own look and sound and raised the top resolution to 2K. MiniMax H3 is the open base model, and Morphic runs it along with Morphic H3, a variant that adds native audio.
No. HeyGen Video 1 runs on HeyGen and a few model services. On Morphic, the model it is built on is available: MiniMax H3, and Morphic H3, which generates native audio with the video in one pass.
HeyGen Video 1 and Morphic H3 both generate the soundtrack with the picture in one pass. HeyGen has tuned its version for its own sound, and Morphic H3 is the native-audio variant of the same base model on Morphic. The base MiniMax H3 by itself is silent, so for audio on Morphic you want Morphic H3, or Veo 3.1 when a clip turns on spoken dialogue.
On Morphic, Morphic H3 generates video with native audio from 5 credits per second, and MiniMax H3 from 19. HeyGen Video 1 is billed per second on the services that host it, with the 2K tier costing more, and it cannot be run on Morphic at all.
Both hold a scene together well, since they share a base model. On Morphic you have an advantage beyond the model: every take lands on the Canvas, so you can generate several shots, line them up, and cut them on the timeline in one workspace, which is what keeps a multi-shot scene consistent in practice.
