I thought I would be able to let this go, but I have now been searching on and off for a few days and can't seem to find this footage.
It's the clip(s) feature here: https://www.youtube.com/watch?v=ciZYI9yK_Jk
I could maybe assume he's using some custom content but in a similar video he is clearly using either Enter5 or NeoGlitch featured on the Resolume store so I am super hopefully that this awesome triangle heavy loop is out there somewhere! I'm not sure but I think there are maybe 2-3 clips being used in the 7 second video, though I'm hoping they are all from the same pack.
Thanks in advance and a special thanks to Arvol for the potential leads in slack!
