MiniMax H3 AI Video Generator
Text or image to 4-15s video with the sound already in it
Most video models hand back a silent MP4 that you then have to score. H3 generates dialogue, sound effects and music in the same forward pass as the picture, 32 kHz stereo, dialogue stable in eleven languages - so there is no silent version to fix later, and no mute toggle, because the sound is not a separate layer. Four inputs, 4-15 seconds at any whole second, 24 fps, 768P or 2K, six aspect ratios. First clip runs with no account. Independent third party, not affiliated with MiniMax.
Hi Product Hunt 👋
I kept hitting the same step in every AI-video workflow: the model hands back a silent clip, and then you go find music, cut sound effects, and if there is dialogue you dub it and hope the lips line up.
MiniMax H3 does not work that way. The audio comes out of the same forward pass as the picture, at 32 kHz stereo, with dialogue stable in eleven languages. There is no silent version to fix afterwards - and no mute toggle either, because the sound was never a separate layer.
This is a browser front-end for that model, plus the documentation half. Every specification on the page links to MiniMax's own API reference with the date it was last checked, which sounds dull until you notice how many H3 write-ups still state a 5-second duration floor (it is 4) or a 1080P tier (there isn't one - it is 768P or 2K, nothing between).
Two tools are free and need no account at all: a prompt generator that prints H3's three-field structure and checks it against twelve rules, and a video-to-prompt tool that reverses a clip back into an editable prompt. Both run at https://minimax-h3ai.video without signing in, so you can judge the output before spending anything.
Being explicit about what this is: an independent third-party interface, not affiliated with or endorsed by MiniMax. The engine behind the free no-account clip is openly stated not to be H3 itself; H3 bills real GPU time and sits on paid plans. Failed generations refund automatically.
Happy to answer anything about where the model actually breaks.
