A7iii Videosetting for bright days

[Rozema]

Hello guys,

New to this forum and really can use your help with my videosettings.
I am doing a lot agricultural video's lately with my recent bought A7iii.

I programmed the "1" and "2" for HD (120 fps) and 4K (24fps).
4K - 24 fps - F2.8 - ISO auto - 1/50
HD - 120 fps - F2.8 - ISO auto - 1/250.

I did some test shooting in the evening which produced great video's

The problem:
The video's I made were produced during a really bright day (the were producing hay/silage).
The video's really seem overexposed. Changes the white balace or picture profile does not help.
Changing the ISO was not sufficient. I would like to keep the F2.8 the same for the bokeh.
Only adjusting the shutterspeed was sufficient.

What would you guys advice?

Thanks in advance!

Would having a variable ND filter on the lens help? If I'm doing outside video I find this essential to keep the correct exposure within the desired frame rate/shutter speed ratio.
