Fable Video — realistic, emotional video generation

Three local engines are vendored inside this plugin (vendor/), plus a cloud render backend. Pick by output type:

Engine	Use for	Entry
ViMax (vendored, `vendor/vimax/`)	cinematic AI films from an idea, script, or novel: screenplay → storyboard → shots → keyframes → clips → final cut	`python3 vendor/vimax/main_idea2video.py` / `main_script2video.py` (see repo readme)
AI4Animation (vendored, `vendor/ai4animation/`)	physically realistic character animation — muscle-driven motion, locomotion, emotion poses, quadrupeds	`python3 vendor/ai4animation/Demos/<demo>/Program.py` (weights fetched once via `scripts/fetch_models.py`)
Remotion	programmatic video (motion graphics, data-driven reels, subtitles, brand templates) rendered deterministically from React	`vendor/remotion-starter/` → `npx remotion render`
Runway API (cloud, key required)	highest-realism text/image→video clips when local generation is not enough	the `runway-api` skill (`rw-generate-video`)

Realism & emotion rules (apply to every engine)

ViMax's own shot schema (vendor/vimax/interfaces/shot_description.py) is the quality bar. Every shot must carry:
