MiniMax H3 tip: copy-pasting your prompt 3 times beats rephrasing for video adherence
BossSev38 · reddit · 2026-10-09
A Reddit user shares hands-on experience with MiniMax H3 reference mode for video generation: when the model ignores instructions, copy-pasting the entire prompt multiple times works best — 3 repeats is near saturation and 10 adds nothing.
Takeaways
- Includes a full structured prompt template for character swap into a reference video, with sections like subjectdefinitions, retentionanalysis, and detaileddescription specifying what each input (identity image, motion video, audio) contributes.
- More detail helps: pin down camera and character position/rotation (e.g. "closeup facing camera", replace "dancing" with "walking left").
- Recommends Resmultistep sampler with sgmuniform scheduler — fast with few hallucinations.
- Local setup: int4 build on an RTX 5070 with --enable-manager --disable-comfy-compiler --disable-pinned-memory.
- Increasing steps or resolution did not improve adherence.
