Light Flickering problem

I am trying to create animation using matinee, but after rendering I get ugly and distracting light glitches. Link to movie: - YouTube . Anyone know why this is happening? Any solution?
Thanks for help

I don’t know exactly what’s going on, but if I have to guess, it might be problem with anti aliasing. Try switching your AA Method in post process. I don’t do Archviz much, someone know about rendering might know more about it.

Does rendering out at a higher resolution reduce the glitches?
