Reddit user builds Shotboard timeline workflow for directed long-form video with MiniMax H3
Acrobatic-Example315 · reddit · 2026-09-20
A Reddit user shares an experiment driving MiniMax H3 long-video generation with an IAMCCS Shotboard timeline: positioned guide images, global + local prompts, timing, audio policy and continuity all live in the Shotboard while the backend generates windowed chunks. The goal isn't just longer clips but a directable relationship with time — choosing when a visual state appears and letting H3 find the motion between states. Practical tips: start short, keep guides visually reachable from one another, test at moderate resolution first. A simplified workflow is posted in the comments, with a larger advanced branch in progress.
