No Roman numerals. No Arabic numerals. No left-to-right reading direction. No assumed orientation. Something that works in a mirror, in zero gravity, in any language spoken on Earth or beyond it.

How can complexity be reduced? Perhaps fifteen minutes could become the new smallest unit, then 24 times 15 equals 96, which is divisible by 6 (and 6 might be the most complex shape that can be perceived quickly). So 4 units is one old hour. To be continued.
p.s. Minutes and seconds should probably not intersect, it is just visually annoying, they could be aligned so that bigger unit is on top.

Premiere 2025
The problem: Subtitles burned into video on export, but the wanted export is progressive. Result: Weird looking subtitles, like some sort of interlaced brokage.
ChatGPT:
- Select the caption track.
- Graphics and Titles → Upgrade Caption to Graphic
- Premiere creates Essential Graphics text layers.
Those render per frame, not per field.
endChatGPT
They still look weird if video is exported as progressive.
