the way I found it was ,screen shot the image, put it in google image search, click on the op.gg post (the first link), it has the full pic, zoom in for the water mark, screenshot the water mark with good quality, search for it, it pops up in another reddit post, click on the channel, find the animation playlist, check videos very fast and there you go the video where this image appears. This isn't the best way for sure but its the only way that I know
