AI platform for generating and editing videos and images
MiniMax H3 is an open-weights, general-purpose multimodal video model from MiniMax. It accepts text, images, video, and audio inputs, and generates native 2K footage at 24 fps with synchronized dialogue, sound effects, and ambience in the same pass. It is also known as Hailuo 3 and is the successor to Hailuo 2.3.
What is MiniMax H3? MiniMax H3 is a general-purpose multimodal video model from MiniMax. It can interpret text and reference media, plan motion across a shot, and generate video with synchronized dialogue, effects, and ambience.
Is MiniMax H3 the same as Hailuo 3? They refer to the same model family in common product usage. MiniMax H3 is the official model name; Hailuo 3 is the name many users and third-party tools use to connect it with earlier Hailuo releases.
How long can a video be? This generator offers 5, 10, and 15-second clips. For a short clip, describe one clear action arc rather than packing in several unrelated scenes.
Does MiniMax H3 generate sound? Yes. H3 can generate dialogue, sound effects, and ambience together with the visuals. Include the speaker, exact spoken line, environment, and desired sound texture in the prompt when audio matters.
Which resolutions and ratios are available here? This generator offers 480P, 720P, and 1080P, with 16:9, 9:16, 4:3, 3:4, and 1:1 ratios. Choose 9:16 for vertical social video, 16:9 for landscape storytelling, and 1:1 when the destination needs a square asset.
What is omni-reference? Omni-reference is H3’s ability to use images, video, and audio as coordinated guidance for identity, motion, visual style, and sound. This page currently provides text-to-video plus first/last-frame image guidance, a focused subset of the full model.
Is MiniMax H3 open source? MiniMax describes H3 as an open-weights model. Self-hosting still requires suitable GPU capacity, model files, and a compatible inference stack; this page is the simpler hosted path for occasional generation.
How is H3 different from Hailuo 2.3? Compared with Hailuo 2.3, H3 adds native synchronized audio, richer multimodal reference control, longer instructions, higher native resolution capability, and open weights. The practical benefit is more control over a complete shot, not only a stronger first frame.
Can I start for free? You can write a prompt and prepare reference images before signing in. Clicking Generate Video for Free opens the account dialog; new accounts receive 20 credits, enough for two default 480P, 5-second generations.
How should I write a prompt that produces controlled motion? Write the subject and goal first, then describe the action in order, the environment, camera movement, lighting and sound, and the final frame. One coherent sequence usually gives the model clearer direction than a list of unrelated visual adjectives.
When should I use first and last frame images? Use a first frame when the opening composition, character, or product must be specific. Add a last frame when the shot needs to arrive at a particular composition; your prompt should explain the motion that connects the two images.
How long does generation take, and can I leave the page? Generation time varies with clip length, resolution, and queue load. After a task is accepted, its state is stored in your account history; keep the page open for live progress, or return to the history page to check the completed result.
What happens if generation fails? A failed task shows a specific error whenever the provider returns one. Credits reserved for an unsuccessful task are restored automatically; if a status remains stuck, use the task ID when contacting support.
Can I use generated videos commercially? Commercial use depends on the model and service terms plus the rights to every prompt, logo, face, voice, and reference asset you provide. Generation does not automatically clear copyright, trademark, likeness, or voice rights.
May I use face or head swap on anyone? Only use media you own or are authorized to edit. Unauthorized impersonation and deceptive use are prohibited.
