MiniMax H3:
Native 2K, Same-Pass Audio.
MiniMax H3 is MiniMax's general-purpose multimodal video model (also known as Hailuo 03) — built for detailed prompt following, first/last-frame control, and native stereo sound at up to 2K. Generate from text or animate still frames inside the VidTool AI workspace.

What Makes MiniMax H3 Different?
MiniMax H3 produces 4–15 second clips at 768P or native 2K with stereo audio generated in the same pass — dialogue, ambience, and effects can be directed from the prompt rather than dubbed afterward.
On VidTool AI, MiniMax H3 supports text-to-video with six aspect ratios, or image-to-video with one first-frame image (or first + last frame). Duration is an integer from 4 to 15 seconds, with prompts up to 7,000 characters for shot structure, camera, style, and sound.
Four Capabilities That Change the Workflow
Each one maps to a production need — from prompt-only drafts to frame-anchored motion.
Text-to-Video
Generate from a detailed prompt alone across 21:9, 16:9, 4:3, 1:1, 3:4, 9:16. Aspect ratio is required for text-to-video — adaptive ratios are not used in this mode.
First & Last Frame
Upload one image as the opening frame, or two images to define where a shot starts and ends. The model fills motion and audio between the anchors.
768P & Native 2K
Choose 768P or 2K output. 2K targets higher detail for finished clips; 768P is suited for faster drafts and iteration.
Native Stereo Audio
Audio is generated with the video in one pass — direct dialogue, music, ambience, and effects in the same prompt as the visuals.
