MiniMax H3 Action Director 9 Combat Presets

MiniMax H3 action director workflow with 9 combat presets. One graph covers text-to-video, first/last-frame and dual-character reference-to-video, with preset LoRA combos that choreograph punches, blades and gun-fu between two characters.

Main features:
- Three modes behind control switches: text-to-video (20 steps), first/last frame (20 steps), reference-to-video with character A/B images (25 steps)
- 9 combat presets (A0-A8): A0 basic fists, A1 high-dynamic repair, A2 two-person attack/defense (default), A3 comprehensive martial arts, A4 blade weapons, A5 gun-fu, A6 continuous gunfight, A7 close-quarters gun-fu, A8 general action repair
- Auto LoRA management: H3_Combat_V2 + H3_Fight_Flow_V1 applied automatically per preset (0.65/0.25 refine weights); Bunny_weapon_combatV1, GunFu, Motion_Repair_V2 available for manual tuning
- Optional second pass: 896x512 base pass refined through the MiniMax H3 3D latent upscaler to fixed 1344x768 (low-noise 0.30 denoise); otherwise the official ResolutionSelector picks aspect ratio and megapixels with automatic 32-pixel alignment
- Duration input in seconds auto-converts to the H3-valid 17n+5 frame grid at 24fps
- Native audio output (VAEDecodeAudio + CreateVideo/SaveVideo)

Suggested workflow:
1. Pick the mode with the left control switches, then upload the matching inputs (prompt only, first/last frames, or character A/B images)
2. Choose the combat preset (start with A2) and enter the video duration in seconds
3. Queue the graph; the preset LoRA combo, sampling and optional 1344x768 refine pass run automatically
