# MiniMax-H3

> MiniMax-H3 text/image/multimodal video, Context IR, 480P–2K, up to 30s, and 768P→2K regeneration.

# MiniMax-H3

Supports **text-to-video**, **image-to-video (first/last frame)**, and **multimodal reference**. Resolution `480P` / `768P` / `1080P` / `2K`, duration **4–30** seconds.

| Action | Method | Path |
| - | - | - |
| Create | `POST` | `/v1/videos` (also `/v1/video/generations`) |
| H3 Context IR | `POST` | `/v1/videos/h3_context_ir` |
| 768P → 2K regen | `POST` | `/v1/videos/regeneration` |
| Get result | `GET` | `/v1/videos/{task_id}` |

**Host:** `https://api.omniall.ai` · Auth `Authorization: Bearer sk-...` · Model: `MiniMax-H3`

## Resolution & duration

| Field | Notes |
| - | - |
| `resolution` | `480P` / `768P` / `1080P` / `2K` |
| `duration` / `seconds` | **4–30** seconds (integer) |
| Context IR | Optional per-call surcharge when enhanced understanding is enabled (see model details) |

## Modes & ratio

| Mode | When | `ratio` |
| - | - | - |
| t2va | text only | **required**, not `adaptive` |
| i2va | first/last frame | forced `adaptive` |
| r2va | `reference_*` | optional (default `adaptive`) |

**Exclusive:** frames vs `reference_*`.\
**Equivalents:** `first_frame_url` ≈ `first_frame` ≈ `image` ≈ `images[0]`.
