Oh I didn't expect anyone to reply. Hence no links with preset explanantions. I also have to apologize for my bad english and potential lack of explanations. The gif itself comes from https://blurbusters.com/crt-simulation-in-a-gpu-shader-looks-better-than-bfi/ which has links to the shadertoy and github pages if you are interested in the code itself. It's open source.
To summarize in a few seconds what the purpose of black frame insertion is... Well take a look at this https://testufo.com/blackframes (epilepsy warning) it is a way to refresh your screen without needing new frames from your output. However it only applies to eye tracked motion rather than both it and fixed gazed eye vision. As a proper full refresh rate source would. It comes alongside other cons. Like flicker being too visible at low refreshes hence the epilepsy warning. Specifically lower than 85hz. So video containers and displays need to be 120hz minimum. Even if the content is 12-24fps That's not exactly acceptable for production hence why you have never heard of it.
Here's a more general explanation on pixel motion clarity. https://blurbusters.com/blur-busters-law-amazing-journey-to-future-1000hz-displays-with-blurfree-sample-and-hold/ yes. You can actually see 1000fps and beyond.
Which brings me to the point of this thread. The crt electron beam simulation through software. Crts refreshed their displays (summarizing incorrectly technicalities) every 1 milisecond. Giving your content a refresh rate of 1000fps in some aspects. Although resolution bottlenecks how much fps will show. As the article attempts to explain. 240p tops at 240fps, 480p dvds from the 00s top out at 480fps etc. etc. Those snes 240p 60fps games like super mario? They were more like 240fps. Later on ps2 games at 480fps like guitar hero and medal of honor. Of course in the 2000s pc gamers were playing at 768p / 900p. Battlefield 2, quake 3 900fps etc etc.
