How do you make motion videos with Opus 5.5 (as a beginner)?

Beginner guide to short motion videos with Opus 5.5 in an agent that has a shell: pick a tiny job with fixed length and aspect ratio, keep a references folder and a note on what good looks like, ask for springy time-based rendering, export stills for one critique pass, and reuse the folder so later sessions keep the same look. Credits the Movez course for the core idea.
