Hi @TaZexCaT
Also, If you go to this thread again:
https://forum.shotcut.org/t/gl-transitions-made-using-elusiens-gl-transitions-overlay-generator/9655
and scroll down to the 6th post:
@sauron kindly made a zip file with all @elusien’s GL transitions in HTML file format.
You can then choose which effect you want and apply the HTML file to the transition as per sauron’s instructions. It’s really easy to do!
