I'm just gonna say it - a bunch of stuff here replicates existing companies and extends their life span [this bit isn't all that bad, actually] - but there are some original pieces - take for example, Havik - a friend of mine is invested in that one
I mant about the opening links. As I said before, you can handle the other ones who only need minor edits (like cutting off borders and removing the screenbug) at the same time you're handling the PTV ones to make it faster.
The clip of the 1990 ZRF Eurdevision ID that I found is a little better in quality than the one at https://youtu.be/pkyXCJsttBI and the color is a little more corrected and better quality. So, I think the 1990 ZRF Eurdevision ID looks good enough for right now.
