I am also now extremely curious as to why flv out of all the formats you could have chosen XD Were you using Flash as an editor maybe?! D:
Given the rigmarole involed in getting that titchy little video out of the flv format and into something watchable I'm going to unconditionally pardon all the artefacts I picked up, that was a solid effort.
I noticed that I have all flv files in folder old-google-video. So, Google Video was the first google videoservice, before YouTube and when they integrate it, we got the option to download all that old files. So, it's not original...
Interesting choice on their part as well, maybe it was the most efficient video format (to some value of video format) at the time, wow O_O
I don't know, but probably yes. Also, noticed that I should upscale less, just to 756x365 that's native, not to 1280x720, now looks to artificial 🤔
