How to make a Hailuo 3.0 clip in Root
- Add MiniMax H3 to a project. Open a project, add a Video Gen node and choose MiniMax H3 for text or image to video, or for reference to video. Wire in a still or references if you have them. To swap a character or object, add an Edit Video node to a clip you already have instead.
- Pick the size and the quality. Pick 1080p or 1440p. High quality is the default; Turbo is quicker and costs less. For a long clip at 1440p, pick Turbo.
- Write the shot and run it. Say what happens and what we hear: the action, the camera, the line of dialogue, the sound around it. The price shows before you run it, and the clip lands in your project.
