Multiple video planes synced at the same time

I’ve been playing around for years in UE, but only recently started looking at it as a possible tool for band music videos.

I’m trying to wrap my head around how I would have 3 or 4 different videos playing on planes simultaneously but all are synced together. In other words, for a band, a separate video for the vocalist, bassist, guitarist, and drummer, but they would be synced to the music track. I want the ability to blue/green screen each member separately, then place them in different parts of the environment.

I’ve been successful in getting 1 video plane working properly, but just can’t seem to figure out how to get the others synced so they all play properly matching to the music.
