No face-swapping across 12 one-take shots: a full MiniMax H3 short-drama workflow
lxfater · x · 2026-09-10
A detailed first-hand workflow for making a 2min05s short drama with 4 characters and 12 one-take segments using MiniMax H3 via the official MiniMax Design agent tool, solving H3's two biggest long-video pain points: face consistency across multi-character shots and segment transitions.
Key techniques:
- Face consistency: prepare the script plus 22 continuous state images first; each segment's first/last frame comes from this set, with the previous segment's last frame being the next one's first frame — text prompts alone can't keep characters consistent.
- Generation: hang first/last frames on each segment in the Design canvas with dialogue and actions; the first segment generates with exact dialogue, the remaining 11 run in three batches.
- Staging: use the 3D director stage — feed it a hospital-room floor plan and it builds the room, places 4 characters and cameras; wrong-facing characters are rotated by key press without rerunning.
- Editing: 12 segments stitched with title cards and subtitles, with 6 different transition methods for the 11 seams.
The author notes many people stall at deploying open-sourced H3 (VRAM, environment, prompt format), while MiniMax Design wraps it in an agent — no deployment needed, runs on Mac and Windows.
