Sup guys. Anyone on here experienced in After Effects?
I've been experimenting with various 80's retro neon/outrun kinda vfx for use in some fake skate and fingerboard parts and there is this particular effect in this counter strike edit which would be perfect. Problem is, I have no clue how to do it.

I'm not a newbie or anything with after effects but I just can't for the life me figure this out.

The effect is at 00:16, the cyan+pink trail on the weapon as it's swaying.

He links the aep files in the description but I don't have the plugins they use.


Oh and the clip I'm editing has a completely static background.

Any help is appreciated, even if it's just a search term that would lead me in the right direction.
