I believe these only apply when you are using the Fujifim M mount adapter

Just a quick update. I made quite a rookie mistake. So I want to check the connections settings in the camera and managed to get a couple of things working so the screen isn't black anymore I had it on USB card reader and moved it to tether connection, this managed to solve the initial issue of having the black screen, however some of the settings still have issues so I'm probably going to research a little bit more in post here to kind of answer my own question but a managed to at least get the screen working and the camera 😅

I hesitate to give advice about safety but it does tell you in the manual to charge using a cable

After reading some horror stories of batteries swelling up after being charged in the camera (and they couldn't be removed), I bought a set of two Neewer NP-W126 batteries with a double charger from Amazon. Didn't notice the "S" was missing from the end, but since the original battery didn't last all that long, I figured 3 batteries would be better than one.
It turned out fine. I do a lot of wildlife shooting and one battery will definitely not last all day. The original battery lasts longer than the Neewers, but not so much that the difference is worth the extra expense. The charger will run off a USB-C or micro USB cable so it's compatible with almost anything and it will work in the field if necessary.
Note: I never shoot 4K video, but if I did I would probably use stock batteries or an external USB-C power bank.

Hello Andrew.
To set video options as you like, you have to turn the main button(Auto, M, S, A, P etc) to VIDEO. Then you set the options you like from menu (Manual focus) and for starting capturing video as the settings you have done, you push the Shutter release button, not the red one.
I think that will solve your problem.
