From Prompt to 2K Motion with MiniMax H3
MiniMax H3 moves from text, first and last frames, or reference media to 2K video, while H3 Developer adds generated audio at 480P, 768P, or 2K through one pay as you go Atlas Cloud API workflow.
2K MiniMax H3 Text to Video
Turn a written prompt into a cinematic 2K clip lasting 5 to 15 seconds. Choose 16:9, 9:16, 1:1, or adaptive framing to match the destination. Because the route starts from text alone, teams can move from a shot concept directly to rendered motion. It fits hero scenes, trailers, and campaign assets that need high resolution delivery.
First and Last Frame Direction
Begin with an approved first frame and add an optional last frame to define where the motion should finish. A text prompt directs the action between those visual anchors. The standard image route returns 2K clips from 5 to 15 seconds, while the Developer route adds 480P and 768P choices. Use it for product reveals, key art animation, or planned transitions.
Reference Guided Subject Continuity
When a recognizable subject matters, supply a reference image to guide a new 2K video lasting 5 to 15 seconds. The prompt defines the scene and action while the reference anchors the subject. H3 Developer broadens the route to one or more reference images or videos and can generate audio. This supports recurring characters, connected promos, and consistent product storytelling.
Generated Audio with H3 Developer
Choose H3 Developer when picture and generated audio belong in the same request. Text to video, image to video, and reference to video routes each support 480P, 768P, or 2K output. Start from a prompt, animate an opening frame, or preserve a subject from reference media without leaving the family. The route suits narrative concepts, character moments, and audiovisual campaign previews.
One MiniMax H3 API Workflow
Atlas Cloud places H3 text, image, and reference routes beside the three H3 Developer routes in one API workflow. Standard H3 pricing is $0.038 per generated second, while H3 Developer carries a standard price of $0.05 per second. Pay only for the route and output you select, then change model IDs as production needs shift. This structure keeps testing and deployment inside one integration.
Same Prompt, Three Engines: MiniMax H3 API Head to Head
Every clip in this set comes from one identical prompt sent to the MiniMax H3 API and two other video models hosted on Atlas Cloud, so motion, sound, and instruction fidelity can be compared without changing a single word.
15 seconds, 16:9 landscape short video. Live-action footage of a late-night self-service laundromat, blended with hand-drawn glowing animation into a mixed-media image. A small self-service laundromat, its fluorescent lights faintly flickering; inside are running washing machines, plastic laundry baskets, and an old bench, with a single sock lying on the floor. The whole space is quiet, carrying a faint, nostalgic mood. It has the texture of one-handed handheld phone footage, with noticeable camera shake; the white fluorescent light causes the exposure to fluctuate between bright and dim; glass surfaces carry ambient reflections; there's a focus lag when the lens moves close to objects. The image should not be as polished and orderly as a commercial ad — the overall feel should be like a genuine documentary snapshot, as if you stumbled in by chance late at night and grabbed the shot while chasing some strange, dreamlike vision.

First-person perspective · eye-level height · handheld gaming camera Scene: The shot simulates a player operating a modern-warfare FPS game, both hands holding an assault rifle while slowly advancing along the outer perimeter of a military base. The player moves forward along a road beside cover, the crosshair sweeping across the passage ahead; after a brief pause, they fire a few rounds toward a distant objective, then continue pushing forward — like the live gameplay footage of an ordinary player. Lighting: The cool-toned natural light of a modern military base interweaves with smoke and muzzle fire. The image is realistic and crisp, with the metallic weapon and the battlefield dust and haze carrying a AAA-game quality. Camera work: The camera has a slight handheld sway as the player moves — first advancing slowly, then making small left-and-right sweeps to observe, with a subtle recoil shake when firing, before finally continuing to push steadily forward.

Production Workflows Built Around MiniMax H3
Whether a brief begins as copy, an approved still, or a recurring subject, MiniMax H3 can shape product launches, storyboards, social variants, character series, pitch films, and audio supported concepts through the matching generation route.
Product Launch Films with MiniMax H3
Animate an approved first frame in 2K, then use an optional last frame to guide the finish. Brand teams can turn key visuals into product reveals, launch teasers, and polished campaign moments.
Recurring Characters Across Short Series
When continuity matters, supply a reference image so the generated 2K clip keeps its subject recognizable. Studios can build recurring character shorts, connected promos, and branded episodes around a consistent on screen identity.

Start with a prompt or source image and let H3 Developer generate the accompanying audio. Creative teams gain pitch sequences, character moments, and campaign concepts where picture and sound share one workflow.
Controlled Storyboard Transitions
Guide both ends of a 2K shot by providing a first frame and an optional last frame. Previsualization teams can map reveals, transformations, and scene transitions before committing to final campaign production.
Multi Format Social Variants
Need one concept for several placements? Generate 5 to 15 second text driven clips in 16:9, 1:1, 9:16, or adaptive framing for landscape, square, and vertical social campaigns from the same brief.
MiniMax H3 Text Driven Pitch Films
Turn a written brief into a cinematic 2K clip without supplying source media. Agencies can prototype hero shots, trailer beats, and visual pitches while choosing durations from 5 to 15 seconds.

MiniMax H3 Answers for API Builders
MiniMax H3 is MiniMax's multimodal video model family for creating clips from text, images, and reference media. Atlas Cloud provides dedicated text to video, image to video, and reference to video endpoints through one API workflow. Resolution and audio support depend on the selected endpoint.
You can turn a written prompt into video, animate a first frame with an optional last frame, or preserve a subject through a supported reference route. H3 Developer adds generated audio to its text, image, and reference workflows.
Begin with one Atlas Cloud API key and select the endpoint that matches your available input. Review its playground schema for the required request fields, then submit a prompt with any supported media. Treat the endpoint-specific schema as the source of truth for parameter names and allowed values.
Choose text to video when starting from a prompt, image to video when animating a first frame with an optional last frame, or reference to video when subject continuity depends on existing media. Select H3 Developer when generated audio is required. Parameters should not be assumed to transfer unchanged between routes.
Standard H3 text, image, and reference routes support 2K output with verified durations of 5 to 15 seconds. H3 Developer routes support 480P, 768P, and 2K output. For text to video, standard H3 offers 16:9, 9:16, 1:1, or adaptive framing, while H3 Developer offers 16:9, 9:16, or 1:1.
Generated audio is explicitly supported by the H3 Developer text, image, and reference routes. The verified standard H3 profiles do not state generated audio support, so choose H3 Developer when audio is required.
Atlas Cloud lists the standard price of H3 at $0.038 per generated second and H3 Developer at $0.05 per generated second. Costs scale with the generated duration on the selected route under pay-as-you-go billing.
Treat each prompt as a concise production brief that states the subject, scene, action order, camera behavior, sound needs, and constraints. When references are included, assign each asset a clear role such as identity, motion, or composition so the instructions do not compete.
Use the managed API when you want pay-as-you-go access through one OpenAI-compatible key without operating model infrastructure. Local deployment is better suited to teams that need direct control over open weights and can independently assess hardware, operations, and licensing requirements.
