One Remotion scene, three aspect ratios: a small layout-rules experiment

[kamilkaczmareksolutions]

I tested one fictional Remotion demo at 16:9, 9:16 and 1:1. One generated version received a short rules file: proportional regions, font sizes based on the shorter side, a column layout for square frames, and a still-frame check in each format. That version avoided clipping seen in the control. This was one unreplicated test; the designs also differ, so it isn't a clean causal benchmark. Comparison below.

When you last reused a scene across aspect ratios, what did you fix by hand? Would you try a small rules file for your next project?
