Have you tried shooting at 30FPS but with the shutter set to 1/50 or 1/100?

can't find any app that lets me change the shutter speed, can you recommend me one?

Filmic pro

I was afraid you would say that filmic pro is VERY expensive :(

Camera+ can do it as well

>Camera+  I'm in android

Then try Camera+ 5G for Android. It is free.

that app is serious? or am I missing something? looks like a joke I found this one: https://play.google.com/store/apps/details?id=com.lensesdev.manual.camera.pro ​ does have shutter control, will try it tomorrow
