With one effect i can tell you SABER from video co pilot. if you animate some text full of these ______ or ——– and animate those on a mask source using the energy preset on saber you could get some pretty gnarly results…
I updated to sierra and regretted it…But then i upgraded again and everything seems to be fine…of course im talkibng about everything else…paint on ..my wacomb tablet is still useless with it..but i dont have 2017 AE
well you could get some really interesting effects with Saber plugin from video copilot…or perhaps even the lightning effect with very low complexity..spline and of course alpha
Conisdering the style of the rest of the video is with animating masks, it really looks like the same blobby shapes from the rest of the video..just squeezed into the shape of a curved path.. but how can that be done without plugins…hmmm
