Frequently asked questions about H3Max
What formats does H3 Max support?
Text-to-video and image-to-video (opening frame + optional ending frame). For complex multi-reference workflows combining images, video clips, and audio as references, use standard H3 instead.
How long does video generation take?
Approximately 2.5 seconds backend inference for a 5-second 768P clip; additional time added by queue processing and prompt expansion.
Can H3 Max edit existing videos?
No; H3 Max generates new videos. For replacing elements in existing clips (character, outfit, background), use standard H3.
