Reference-driven 3-15s video generation at $0.084 per second.
MiniMax H3 Max text to video is the text-only path of MiniMax's post-trained H3 Max line—and it is built for speed. A 10-second clip often comes back in roughly a dozen seconds, so you can draft, revise, and lock shots in a tight loop.
You describe the shot, camera, and sound; the model returns a short MP4 with matching audio at 480p or 768p. Use MiniMax H3 Max text to video when you want to invent framing from words rather than locking a still.
