Beyond video: Users uncover hidden image editing and voice cloning capabilities in Minimax H3
Resident_Sympathy_60 · reddit · 2026-08-03
Reddit users have discovered that Minimax H3 is an all-in-one model that extends well beyond standard video generation (t2v, i2v, r2v).
Key Hidden Features:
- Image Editing: By setting duration to near-zero with a reference image, it can perform face swaps and scene transitions.
- Audio Generation: Inputting dialogues at specific resolutions enables TTS voice cloning with emotional expression. On a B300 GPU, it operates near real-time, taking 8 seconds to generate 10 seconds of dialogue.
- Background Removal: It can directly remove elements from the background via prompting.
Currently uncensored, the community is actively exploring further capabilities while awaiting LoRA support.
