H3 Max is a video generator that turns a text prompt or still image into a 5–15-second clip with synced audio. It is aimed at video creators and teams making ads, product spots, brand films, explainers, UI motion, or game cinematics.

Write a prompt or upload a still image to create a video clip.
Set a clip length of 5, 10, or 15 seconds and choose a supported resolution.
Add a start frame and optional end frame to guide the shot’s motion.
Choose an aspect ratio for text-to-video clips, then review and generate another take.
Create dialogue-led clips with audio rendered in sync with the video.

Audio is rendered with the video rather than added in a separate pass, and the workflow supports revising a prompt and generating another take. New accounts receive 25 credits; paid plans start at $19.90 per month for 1,000 credits.
