$0.02 per second of video in MiniMax H3
Cinematic video generation with the newly updated MiniMax H3 model on NeuralSpace is now available at a special promotional rate of just $0.02 per second. The model features custom fine-tuning by HeyGen (released under the HeyGen Video 1 label), which brings noticeable leaps in visual fidelity: natural physical dynamics for complex objects, stable human anatomy during camera moves, and comprehensive multi-modal reference support across images, video, and audio.
What HeyGen fine-tuning brings to the table
Foundational video generation models frequently struggle with two familiar artifacts: drifting geometry during swift pans and rubbery, unnatural character posture. HeyGen's fine-tuning specifically targets these weaknesses. The engineering team calibrated spatial-temporal attention layers so that objects retain their structural integrity through abrupt perspective changes, while fabrics, water, and hair behave according to real-world physics.
Color grading and contrast handling have also received major polish. Generated clips no longer look washed out or blurry around the edges: the model builds rich volumetric lighting, respects natural depth of field, and cleanly separates foreground subjects from background environments even across sweeping cinematic shots.

Multi-modal references: photo, video, and audio
One of the primary strengths of the tuned MiniMax H3 is its versatile handling of reference inputs. Beyond pure text-to-video prompts, creators can guide scene direction using real assets:
- Images: upload photos as stylistic guides or assign specific start and end frames to anchor the opening and climax of your animation. Characters maintain distinct facial features and wardrobe across the sequence.
- Video references: provide footage showcasing desired camera trajectories or motion pacing, enabling the model to replicate complex gimbal tracking or dolly zooms without tedious manual coordinate prompting.
- Audio: audio tracks can be attached to establish rhythm, mood, and dramatic pacing for the scene.
In the NeuralSpace generator, there is no need to hunt for checkboxes or manual toggles for reference modes. The system automatically inspects your uploaded media and assigns proper roles behind the scenes.
Limited-time promotion: rates valid until November 1, 2026
These introductory rates represent a limited-time promotional window celebrating the updated model rollout. Video generation at $0.02 per second will remain active strictly through November 1, 2026. Starting November 1, 2026, prices for MiniMax H3 generation on our site will increase. If you have upcoming video campaigns, commercial storyboards, or creative pilots planned, securing your generations during this promotional window offers substantial savings.
NeuralSpace operates without mandatory subscriptions or recurring lock-ins: top up your balance with any amount and pay strictly per second of generated footage.
Prompt tips for cinematic results
To get convincing results on your initial generations, keep these best practices in mind:
- Emphasize dynamic action: rather than static descriptions like "night city street", describe camera motion and atmospheric changes: "the camera tracks slowly down a rain-slicked neon street, reflections shimmering across shop windows".
- Specify cinematography details: the model understands standard cinematic terminology — wide establishing shots, macro close-ups, handheld tracking, shallow depth of field, and volumetric lighting.
- Pair image references with targeted motion: when using a character photo, dedicate your text prompt to the action itself — for example, "the character turns their head towards the lens, a subtle breeze stirring their hair".
How to start generating with MiniMax H3
Creating your first clip takes just a couple of minutes in your browser:
- Navigate to the MiniMax video generator on NeuralSpace.
- Enter your prompt describing the camera angle, atmosphere, and action.
- Optionally attach image or video references to guide composition or motion dynamics.
- Choose your desired video duration and click generate.
Your finished clip will be saved to your dashboard where you can preview or download it in full quality without watermarks. Explore more in-depth guides and model updates in our blog.
