You might want to use a code block instead of bullet points for your table, the way you presented it is unreadable but I found the info on your blog page.
One of my criteria for video formats is the portability. Like sometimes I might watch something through a web browser which natively supports x264. Yeah x265 provides better compression, and AV1 certainly looks interesting, but they both require the addition of codecs on most of my viewing devices and in some cases that’s not possible.
For most cases I’ve found that CRF25 with x264 works reasonably well. I tend to download 720p videos to watch on our 1080p TV and don’t notice the difference except in very minor situations like rapid motion on a solid-color background (usually only seen on movie studio logo screens). Any sort of animated shows can go even lower without noticeable degradation.
