Brave 7 torture test "Daytime ride 4K 30 FPS" low quality - see any difference?

Ok I'm trying to export the video from video pad editor at the "low" quality setting and I can't really see a difference. Can you guys? Comment below. It knocked the filesize down to 3.99 gig for 9 mins which is getting more reasonable. I'll try and scale it down to 2K next to see how low I can get it for it to be reasonable to watch.
