Runway just added MiniMax H3 to its growing roster of frontier video models, making the newly launched model available directly inside its creative platform the same day MiniMax officially released it. For creators, that means no new account, no new subscription, and no new workflow to learn. H3 is simply there, alongside everything else.
The addition is a small announcement with a larger story behind it. Runway is quietly repositioning itself from a video model company into something closer to a creative operating system, and MiniMax H3 is the latest piece of that puzzle.
What H3 Actually Does
MiniMax H3 generates clips up to 15 seconds long at 2560x1440 resolution with native audio and consistent characters across scenes. That combination, resolution plus audio in a single generation pass, is what sets it apart from most of the field.
H3 renders at full 2K pixel density inside the model itself, so crisp detail is the output rather than the result of a separate enhancement pass. In practice, that matters for anyone delivering to a client or publishing on a large display, where upscaled footage tends to fall apart.
- Resolution: 5-15 second clips at 24 FPS with native stereo audio and a 1440p mode.
- Inputs: One H3 API request accepts up to nine reference images, three video clips, and three audio tracks, capped at twelve files.
- Editing: Video-to-video editing works from simple natural-language instructions in early demos.
