MiniMax H3 Reference Control

Highest-leverage H3 habit: every attached file has a role, and Full-Reference is a different format from Base I2VA/FL2VA.

Source of record: MiniMax VIDEO_PROMPT_WRITING_GUIDE_ref_en.md.

When to Use

• Identity lock, product lock, style/texture from a still
• Motion / camera / edit rhythm from a clip
• Voice from a recording
• Localized edits (swap subject, sign, line, light)
• Continuation from an existing clip

Don't use for: pure T2VA with no assets (master only). Don't use I2VA when the still is a character sheet, not frame 0.00.
