MiniMax H3 Open Weights Image to Video animates a first-frame image, optionally with last-frame guidance, into coherent 480P / 540P / 768P videos with native stereo audio, 5-15 second duration, flexible aspect ratios, and per-second billing. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

The boxer lowers her guard, looks into the camera and says with a confident smile: "Every champion started as a beginner. See you in the ring." Subtle handheld camera, gym ambience.
Run the open-weights edition of MiniMax H3 on WaveSpeedAI's own GPU infrastructure. This endpoint is separate from the official minimax/h3 API: same model family, independently hosted, with its own 480p/540p/768p/1080p resolutions and per-second pricing.
MiniMax H3 is an omni-modal video model that generates picture and native stereo audio in a single pass — dialogue, sound effects, and music are produced together during generation, never added as a separate dubbing step. Give it a first-frame image plus a prompt and it animates the scene with a matching soundtrack.
The image sets the look; the prompt directs the motion and the sound over time. Write it as a timeline, not a one-line description:
Audio: line with entrance cues: "Audio: quiet room tone, a soft piano melody that swells at 3s." Omit this and the model picks a soundtrack for you.First / last frame (optional) — supply last_image to lock the ending; the model generates the motion between the first and last frames. Great for a controlled emotional arc.
Tips
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Desired motion, camera movement, and an Audio: line for the soundtrack. |
| image | Yes | First-frame image URL. The output canvas follows this image's aspect ratio. |
| last_image | No | Optional last-frame image URL. When set, the video interpolates from the first frame to this frame. |
| resolution | No | 480p (faster, lower cost), 540p (1.5x the 480p price), 768p (native canvas), or 1080p (full HD, 2x the 768p price). Default: 480p. |
| duration | No | Output length in seconds, 3–15. Default: 5. |
| seed | No | Fixed seed for reproducible output. |
| Item | Detail |
|---|---|
| Output | MP4 with native stereo audio |
| Frame rate | 24 fps |
| Resolution | 480p, 540p, 768p, or 1080p |
| Duration | 3–15 seconds (snaps to the model's frame grid, so a 5s request lands at ~5.2s) |
| Input | First-frame image (optional last frame for interpolation) |
| Seed | Supported |
Billed per generated second:

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/minimax-h3/image-to-video with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs.

time.sleep(2)Minimax H3 Image To Video is a WaveSpeedAI model for video generation from images, exposed as a REST API on WaveSpeedAI. MiniMax H3 Open Weights Image to Video animates a first-frame image, optionally with last-frame guidance, into coherent 480P / 540P / 768P videos with native stereo audio, 5-15 second duration, flexible aspect ratios, and per-second billing. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/minimax-h3-image-to-video.
Minimax H3 Image To Video starts at $0.1 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `image`, `resolution`, `duration`, `seed`, `last_image`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/minimax-h3-image-to-video.
Reported generation time on WaveSpeedAI is around 82 seconds per request. This is an estimate, not a latency guarantee; queue time and input settings can change the total wait. live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
