Plan multi-shot AI video before paying: story, anchor sheets, a three.js grey-box previz, then a Seedance v2v pack.

What it does

Pre-visualises any multi-shot video (music videos, ads, UGC spots, trailers, explainers) so camera, geography, scale and timing are fixed for free before the paid step. The pipeline runs story structure → storyboard.json → character, product and location anchors → master scenes of 4–11 s → a three.js grey-box previz with auto cameras from plain storyboard words → a Seedance 2.5 video-to-video pack where each run gets its previz clip as @video1 plus refs for only what is in frame. build_pack.py --check blocks costly mistakes (runs without image refs, refs under 300 px, runs over 15 s, shots in no run) before anything is spent. Built on a 36-shot music video and tested on a 6-shot product ad; in review as vargHQ/skills PR #24 and goes live when it merges.

Example output

https://skills.varg.ai/previews/varg-previz.mp4 — The skill's own free step, run for real: its three.js grey-box previz app (vargHQ/skills feature/varg-previz, commit 30620f7) playing the bundled 6-shot sample storyboard 'Morning Drop' (9:16, 12 s, 3 locations). Auto cameras come from the storyboard words (CU push-in, OTS, WS truck right, MS pull out); the set map shows each shot's camera frustums. Captured in headless Chrome at 1440x900, 24 fps, by seeking the timeline frame by frame. No generation credits.
