Animated Interior Lighting

[kotutohum]

Hi,

I've been working on this loop animation, which was supposed to be in 60 frames, camera moving further making a loop illusion. I've used grey glossy material for the plates, blackbody emission for the red lights on the sides.
If I don't place lights per hexagon, it just looks noisy and crunchy.
As I place an area light at the end of every hexagon and move them further with the camera, it glitches: https://imgur.com/a/LNmC7

I really can't solve this and make a smooth, great loop. Any suggestions?
