I shot some footage on an EX-3 for the first time in PAL, 1080 25p 1/50th shutter and there is very noticeable flicker strobing effect. But it's exteriors, theres no light sources, just an overcast day. I know it's not my camera because I switch back to 24p 1/48th, every things fine. Anybody have this issue? And if so, anyway to fix it on the footage already shot?
