MiniMax H3 AI Video Generator

What MiniMax H3 is good at

Clips that need sound and picture to land together. H3 generates stereo audio in the same pass as the frames and follows camera language well. This page takes a text prompt only, so image, video and audio references are not available here.

Where it sits on price

17 credits per second, cheaper than Kling 3.0 here and under a fifth of what Veo 3.1 charges. Native 2K is included, so the upscale step disappears from the budget.

The limit worth knowing

2K is the only tier at launch, and the 768p tier is still a closed beta. That means this model has no cheaper low-resolution draft.

When to reach for it

Music videos, dialogue scenes and ads where the cut has to sit on a beat. For b-roll and quick drafts at the lowest price, Seedance 2.5 at 480p does the job for less.

Writing for picture and stereo sound at once

Sound comes in the same pass, so describe what the viewer hears next to what they see. H3 can produce several shots in one generation, so list them in order with a cue per cut. For example: "A record drops onto a turntable, crackle and hiss. Cut to the needle in close-up as a bass line starts. Cut to a dancer in a dim studio as drums come in." Or "rain on a tin roof, kettle starting to whistle, slow pan across a dawn cabin kitchen". The Cinematic build and Street at night presets are good starting briefs.

Duration choices and sibling models

Resolution is fixed at 2K, so only Duration moves the price. Pick 5, 6, 8, 10, 12 or 15 seconds, from 85 to 255 credits. Use 5 seconds to check that sound and picture match. Go long only for multi-shot pieces. This model has no Format menu. For a vertical or square frame, Kling 3.0 at 27 credits per second offers 16:9, 9:16 and 1:1. Its clips here are silent. Seedance 2.5 at 27 per second allows takes up to 30 seconds and syncs lips to quoted dialogue. Veo 3.1 at 95 per second suits 1080p dialogue masters.
