I can I add a Strobe Effect?

Id like to add a strobe effect to a background image in Resolve. Something similar to the way a filmstrip might flicker. How can I do that in Resolve?

I don't think there's a way to do it within Resolve by itself, but you could get close with BorisFX BCC or Sapphire:

I have tried to simulate flashing light effects as lightning in a room at night using only power windows and Resolve LGG controls, and while I wasn't totally happy with it, the client bought it and was OK with the final look. There is something inherently organic about the inconsistency of real strobe/flashing lights, particularly in the way they change frame-to-frame and alter shadows, and that takes a ton of VFX work or just doing it live on the set.
