this is called Flash Banding...an inherent problem of CMOS imagers.

Hi DXNmedia

what do u mean? how to rectify it?

 

[jasonjoseph]

you can't. google Flash Banding. what u can do in post is combine the two frames to make one frame and add some diffusion filters to make it look like a cool effect.

i meant on a 5dMkII u can't fix it. but other cmos cameras have less flash banding

so far Panasonic have their dedicated algorithm to minimise flash banding during filming, and i think it's the most effective one over Sony's algorithm.
They called it the Flash Band compensation (FBC), and it's available in the AG-HPX372 broadcast ENG camera.
