H3 Max is a web-based AI video generator that turns text prompts or still images into short clips for quickly testing and refining a visual idea. It is designed for product and ad creators, social content teams, and people making previz, pitches, character beats, or motion studies.

Generate video from a written shot brief or a starting image.
Choose 5-, 10-, or 15-second clips in 480p or 768p.
Add a start frame and optionally guide the clip toward an end frame.
Include native stereo audio and refine a take by changing one prompt variable.

The hosted model is built for fast iteration: a 5-second 768p clip often returns in about 2.5–3 seconds, and the output includes stereo audio. A free trial provides one 5-second 480p clip; paid plans and credit packs are also offered.
