Multicast Rendezvous Point Traffic Flow

Probably a pretty basic question but I can't find clarification on my question:

We have HQ and multiple branches. One of our branches was the only one needing multicast for their door video system (on its own subnet) so we had a multicast rendezvous point inside their site. Needs changed and now HQ needed multicast for certain equipment that took higher priority so we moved the RP to the HQ site. The door video system at the branch site still "sorta" works but video either freezes or is very choppy.

My question is: When someone presses the doorbell at the branch site, does that multicast traffic flow to the HQ's RP and then back to the branch site? Or, does the multicast traffic take the known best route which would be only one hop away at the branch site?

Thank you in advance!
