Really not sure about this one. I looked everywhere on the internet and looked for other topics on this but couldn't find anything.

Out of know where my panasonic GH4 playback is slow??

It seems like the smaller I make my aperture and shutter speed, the slower it gets.. I never had a problem with this before? Doesn't matter if I'm shooting in 4k or 1080.

I thought maybe it was just the monitor playback, but when I look at the file on my computer it is also choppy and slow.

Im using Lexar professional 64gb U3 SD Card, have tried many different ones and still same problem.

Again i've searched everything and haven't found anybody with the same problem so i'm a bit worried

Any ideas!??
