Since 2010 or so, most if not all the Collège de France lectures are freely available as video recordings. It’s an amazing resource that can be watched online, or downloaded for a more comfortable experience—if you’re on Paris the entry to any lecture is free too, btw.
Excerpt from Jean-Luc Fournet’s lecture « Le calame et la croix : la christianisation de l’écrit et le sort de la culture classique dans l’Antiquité tardive »
I could easily invert all colours on screen (making white black, and black white) using Windows (or macOS) accessibility tools, but that’d screw up my own Dark mode setup that’s working great for me 99% of the time, and I don’t want that. I just want to invert the video itself.
In Scorpio Player, right-click the video and go to Graphic -> Effect Manager.
Check Invert and, bam, the video is now inverted.
Not that great for our poor lecturer, but so much better to read its slides 😉
