Use the installed Remotion skills. After environment/setup approval, create a separate blank aspect-ratio-remotion project, open Studio and build AspectRatioExplainer at 1080×1920, 30 fps, 360 frames for the key-shot preview. Derive visuals from frame time; preserve diagram proportions except the labelled distortion comparison. Keep the same script inputs. Show Studio before export. Do not render or call paid APIs yet.
