MiniMax H3 — also known as Hailuo-03 — is MiniMax's next-generation multimodal video model, now live on Flixly. It generates polished short videos at up to 2K resolution with native stereo audio, working from either a written prompt or a reference image.
What makes it different
- Native 2K + stereo audio. Video and sound come from the same pass — dialogue, music, ambience, and effects are directed in the prompt rather than added afterward.
- Multimodal understanding. H3 interprets text and images in one context, so a reference image can anchor character or product identity while the prompt drives motion, camera, and shot structure.
- Strong instruction following. It holds shot order, timing, camera movement, and on-screen text more reliably, and renders clearer titles and signage.

How to use it on Flixly

- Pick MiniMax H3 from the model selector.
- For image-to-video, upload your reference image (JPG/PNG/WebP).
- Write a specific prompt — describe the scene, action, camera move, and any dialogue or sound you want.
- Set aspect ratio and duration (4–15s), then generate.
Shorter clips (4–6s) are great for fast iteration; push to 12–15s when you want the audio and pacing to breathe.
