MiniMax H3 AI Video Generator

MiniMax H3 AI Video Generator (also called Hailuo 3) is a browser-based tool that turns a text line, a photo, or a reference clip into a finished 4-15 second MP4 with dialogue, sound effects, and music already mixed in.

What is MiniMax H3?

It's a web interface to the MiniMax H3 (Hailuo 3) model. You either type a description, upload a photo, or drop in reference clips, and the generator returns a video at 768P or 2K resolution, 24 fps, with 32 kHz stereo audio generated in the same pass. The interface runs in any browser, and the same model is also reachable through the official Hailuo app, the MiniMax API, and open-weights checkpoints. This site is an independent third-party interface, not the official MiniMax product.

What makes MiniMax H3 stand out?

• Text to video with native audio — One prompt carries both the picture and the sound; dialogue lip-sync works across 11 languages, and ASMR-style sound effects come from the same pass.
• Image to video — One photo anchors the first or last frame; two photos bracket a full shot. The aspect ratio follows your image instead of forcing a preset.
• Reference to video — Lock a face, style, camera move, or voice using up to 9 images, 3 clips, and 3 audio files, capped at 12 files total (the cap most guides miss).
• 2K re-generation, not upscaling — The 768P result is fed back through the model with your original context to produce a true 2560x1440 frame; there is no 1080P mode, contrary to some listing sites.
• Open weights — H3-Base FL2VA and Ref2VA checkpoints are downloadable and runnable on your own GPU, while Context-IR and Regenerate-2K stay hosted.
• Per-second API pricing — $0.08 per second at 768P and $0.13 per second at 2K, roughly a fifth of Veo 3.1's $0.40 per second list price.

Who should use MiniMax H3?

• Short-form content creators — Generate 9:16 videos, 7-10 seconds long, with room tone already mixed, ready to post without opening an editor.
• Product marketers — Turn a single product still into a lit turntable ad where the click and whoosh land on frame.
• Filmmakers and animators — Shoot dialogue scenes with two speakers tagged (S1) and (S2), and keep the same character across shots using reference images.
• AI developers — Call the API or download the H3-Base open weights to integrate video generation into custom pipelines.

Use cases

• Social media managers: Create vertical videos with native sound for TikTok, Reels, or Shorts without editing.
• E-commerce brands: Make product ads from one photo, with audio cues matched to the motion.
• Video producers: Remix an existing clip by changing the product, signage, or look through video-to-video, keeping the original motion.
• ASMR and ambience creators: Generate no-dialogue scenes with realistic room tones, fur, and whisker-level detail.

How does MiniMax H3 work?

Three steps in the browser: describe the shot and the sound in one sentence (up to 7,000 characters), choose a length from 4 to 15 whole seconds and one of six aspect ratios (21:9, 16:9, 4:3, 1:1, 3:4, 9:16), then download the MP4 with 32 kHz stereo audio already muxed in. Failed generations return credits and cost nothing.

FAQ

Is MiniMax H3 free to use here?

Not on your own prompt. The free engine, Agnes Video V2.0, gives you 3 silent clips per day. MiniMax H3 with audio is the paid product, starting at $24.9 per month. You can watch and download 12 real H3 clips with no account.

Does the free result have sound?

No. Agnes Video V2.0 renders picture only, so free clips come out silent. MiniMax H3 generates 32 kHz stereo audio in the same pass as the picture, which is included on all paid plans. The site does not add watermarks to any output.

Can I use the videos commercially?

Not from this site. Everything generated here is for personal and evaluation use, on every plan. The site is an independent third-party interface and cannot grant commercial rights. For commercial work, generate through MiniMax's own Hailuo app or the official API.

Is MiniMax H3 the same as Hailuo 3?

Yes, same model under two names: H3 in the model card and API, Hailuo 3 in the product line. This site is not official; the official API is platform.minimax.io, and Hailuo AI is MiniMax's consumer app with an earlier model, Hailuo 2.3.

How long does one clip take to generate?

Usually about a minute and a half for a 768P clip, longer for 2K and at peak times. The interface shows real elapsed time rather than a fake countdown. Task records survive 7 days, and the returned download URL expires, so you should move files to your own storage.
