I have set in Googles 3 for video recording everything to manual.
The box for EV is greyed out. Does anyone know how to adjust exposure?
I don't want to touch shutter speed as it is fixed at double frame rate in my settings.

If you have everything set to manual then it makes sense that the EV is unavailable.  It has nothing to adjust the exposure with if you have all the controls on manual.  

Oh  - Dirty Bird!
Good to see you around :-)

Thanks - yes, I just figured: The only way to compensate would be through f-stop settings but that won't work with a fixed f-stop ;-)

Thanks!  I think the EV will become available if you set one of the controls to Auto.

Hi there. Thank you for reaching out. This is normal, the ISO, EV, and shutter speed are related to each other and the range of camera parameters that can be set in different modes is also different. Feel free to use the product. Should you have other inquiries, feel free to contact us. We appreciate your valued support.

Yep like in a normal DSLM
