Turn text or images into short AI videos with synchronized audio — right in your browser.
MiniMax H3 (also known as Hailuo 3) is a free online AI video generator powered by MiniMax's open-weights multimodal video model. Describe a scene in plain text, or guide the shot with a start image and an optional end frame — H3 generates a short video clip with native synchronized audio: dialogue, sound effects and ambience in a single pass.
No video editing skills, no software to install, no expensive GPUs. Just write a prompt and generate.

Two workflows, one model. Enter a text-to-video prompt, or provide a first/last-frame image pair for precise image-to-video control. The generator is already set to the MiniMax H3 model — write, reference, generate.
H3 doesn't just move pixels — it generates dialogue, sound effects and ambience in the same pass as the visuals. Every clip comes out with cinematic, synchronized audio, no post-production step needed.
Attach up to two reference images to lock the opening composition and the final frame. Your prompt explains the motion that connects them — ideal for product shots, character scenes and branded content.
Choose 480P, 720P or 1080P with 16:9, 9:16, 4:3, 3:4 and 1:1 aspect ratios, and 5, 10 or 15-second clips — everything you need for Shorts, Reels and TikTok-ready storytelling. (The underlying H3 model natively outputs 2K at 24 fps.)
Write a prompt → add references → pick the format → generate and refine. Stuck for ideas? The built-in prompt gallery ships with six ready-made examples you can copy, paste and adapt.
New accounts receive 20 credits — enough for two default 480P, 5-second generations. No credit card required.
