Hailuo03AI: Create H3 videos with prompt guides and clear credit costs

Hi Product Hunt 👋 I’m Nolan, the solo maker behind Hailuo03AI. I built it because generating a video is only half the workflow. Before spending credits, creators need to understand duration, prompt structure, camera and sound directions, first-frame preparation, and the actual cost of a batch. Hailuo03AI brings those pieces into one browser workflow. You can create a MiniMax H3 video from text or a first-frame image, choose 5, 10, or 15 seconds, and see the credit total before submitting. The site also includes a prompt guide with original examples, a credit calculator, and practical preparation notes. The current product supports text-to-video and first-frame image-to-video. I do not present every capability in MiniMax’s broader API as available here, and Hailuo03AI is an independent product—not an official MiniMax site. I’d love feedback from video creators: which pre-generation decision causes the most wasted attempts—prompt structure, first frame, duration, aspect ratio, or cost planning? — Nolan
