A Reddit roundup of the latest MiniMax H3 community ecosystem, covering LoRAs, ComfyUI nodes and full workflows:

Technicolor Dreams LoRA: gives dialogue, music, ambience and imagery a unified 1930s–1950s Anglo-American cinematic look.
LineartAnime LoRA: line-art colorization with DiffSynth-Studio.
H3 Recast: swaps up to three people in a clip in one pass while keeping motion, scene and original audio; RecastRoom Studio offers a simpler variant.
H3UpperOutpaint: ComfyUI 'up-painting' node, useful for phone screens with video at the bottom and UI on top.
VBVR LoRA: improves object consistency and action logic, reducing duplication, clipping and interpenetration.
MotionBridge: converts a motion video into a 3D figure motion file (somaskel77) retargetable to any humanoid rig.
Stage: designs cinematic camera moves around a neutral mannequin in 3D, exporting an MP4 guide plus English prompt for H3.
Komikku: turns video into comic pages editable in ComfyUI.
A character-sheet tool generates turnaround sheets from one still; ComfyUI-Picky renders ten takes for picking (needs 24GB VRAM); Transparent-Video generates alpha-channel cutouts in one pass for After Effects.
The author also confirmed Openpose reference images work with H3 Edit for re-posing, provided prompts are aligned.

Bonus: OpenShot 4.1 now lets LLMs like Claude Code or Codex auto-edit videos.
