I stumbled upon the youtube page of a Czech Billiard club, "Billiard Zizkov" .
Here is a 3 cushion match between Dion Nelin of Denmark vs. Jan Ales of the Czech republic part one https://www.youtube.com/watch?v=MwAEP3m_0tM
And the second part of the match between Dion and Jan https://www.youtube.com/watch?v=p3M9oF2Fv_w
I also found a video for the whole match of the Czech national Baulkline 47_2 finals between Marek Faus and Adam Kozack https://www.youtube.com/watch?v=2rLHLMUle6g&t=281s
There are more 3c matches and Baulkline matches on the youtube web page of Billard Zizkov https://www.youtube.com/channel/UCDJweQOtZAAOc81jzCsXSDQ/videos
