The H3 brief, at a lighter tier
MiniMax H3 Lite reads what H3 reads: a written prompt, a first frame, a first and a last frame, or up to 9 reference images with video and audio beside them. MiniMax calls Lite the lightweight H3 variant. Same inputs, the lightest tier.
Sizes and lengths
Renders come out at 480P or 768P, any whole second from 4 to 15. 6 fixed frame ratios: 16:9, 21:9, 4:3, 1:1, 3:4 and 9:16. Adaptive is not offered on this tier, so every render names its shape.
On OpenClips
MiniMax H3 Lite runs in the composer from ⚡21 per render. The composer quotes the exact ⚡ for your length and size before anything runs.
