Need help - Sony A7III shooting video

[wm17959]

I find all these settings confusing. I set the exposure setting to 30p 50M, but I don't know what the shutter speed of the camera should be set to? Can someone provide a source with which I could learn the basics of how to use this camera? I'm having trouble with image blur because I don't have these settings right and I don't know where to find the information. YouTube videos are extremely confusing because they're made for people who already know this information. Sincerely.

use the 180° rule. that means double the framerate and set as speed. for example: if you use 30p than set speed to 1/60s.

before setting aperture or iso you should set always first the speed.

for further infos use „180° rule video“ as keywords for youtube or google or …
