MiniMax H3 AI Video Generator

Most video-model sites make you sign up before you can find out whether the thing works. [minimax-h3ai.video](https://minimax-h3ai.video) puts two tools in front of that wall, and neither one costs a credit or asks for an email. The prompt generator takes plain English and prints it back in the three-field structure MiniMax H3 actually expects, then checks the result against twelve rules that catch the mistakes the API only reports after it has charged you. The video-to-prompt tool goes the other way: hand it a clip you admire and it returns a structured, editable prompt you can change one field at a time. Behind them sits the generator itself - MiniMax H3, the model MiniMax also ships as Hailuo 3. Four ways in: text, image, video, or reference material of up to nine images, three clips and three audio files, capped at twelve files in total. One way out: a finished 4 to 15 second MP4, any whole second, 24 fps, at 768P or 2K, in six aspect ratios from 21:9 to 9:16. The sound is the part that saves an editing pass. Dialogue, sound effects and music are generated in the same forward pass as the picture rather than dubbed on afterwards, at 32 kHz stereo, with dialogue stable in eleven languages. There is no silent version to score later. The 2K path is not an upscale either - H3 sends the 768P result back through itself with your original context and generates it again, which is why small on-screen text survives. Freemium, and the free tier is a published number rather than the word "free": one clip with no account, no email and no card, three a day once signed in. Both run on a free engine we state plainly is not H3 itself. H3 bills real GPU time and sits on paid plans from $24.9 a month. Failed generations refund automatically.
