MiniMax H3 vs HappyHorse 1.1: limits and notes

MiniMax H3

MiniMax H3 generates 4 to 15 second clips at 24 fps in 768p or 2K, each with a native stereo audio track.

Modes

• Text to video: prompt only.
• Image to video: one image becomes the opening frame.
• First and last frame: supply an opening and a closing image.
• Reference to video: up to 9 images, 3 videos and 3 audio clips, 12 reference files in total.
• Regeneration: re-render a 768p clip you generated earlier at 2K. Send the original prompt plus the source clip as base_video.

Prompt expansion

Set enhance_prompt to true and the model first rewrites your brief into a full prompt, adding shot-by-shot structure, camera moves, lighting and a soundscape, then renders from that. Any reference media you attach informs the expansion. It adds a per-token charge on top of the per-second video cost, and is skipped for regeneration because that path reproduces the original request.

Reference media

• Images 256 to 5760 px per side, aspect ratio between 0.4 and 2.5, up to 30 MB each.
• Videos 2 to 15 seconds, H.264 or H.265, up to 50 MB each.
• Audio 2 to 15 seconds, WAV or MP3, up to 15 MB each. Reference audio requires an accompanying image or video reference.
• Reference video and audio apply to reference-to-video only.
• Prompts can be up to 7000 characters and may describe dialogue, sound effects, on-screen text, and camera work.

Billing

• Billed per second of the generated clip at the resolution you request.
• A reference video is billed for its own duration in addition to the generated clip, so a 5 second reference used to make a 6 second clip bills 11 seconds.
• Regeneration is billed at its own lower per-second rate, on the source clip duration plus the regenerated output. Reference images carried over from the original request are not charged again.
• The first 5 reference images are included. Each additional reference image is charged separately.
• Prompt expansion, when enabled, is billed per token.
