Can Lumix G7 "downscale" 4K to 1080 video in the camera ?

Panasonic cameras are great for video (I have 3) but the auto focus for video is pretty much useless. It has no problem focusing, but then it keeps verifying the focus by drifting in and out of focus - called hunting.

It's actually quite easy to deal with this by disabling continuous AF (from the video menu). This way the camera only adjusts focus when shutter release button is half-pressed. This way the AF is also much faster than when continuous AF is on.

I really don't like "fully automatic AF". Even when shooting stills, I use single AF point and AF-S. This way I have the control, not the camera.

I use a similar approach for video, in manual focus mode, but with the shutter release/focus function turned off. That way I can select my focus point by aiming the camera so that the focus box is on the area I want in focus, hit the lock button to focus (or use touch focus), re-aim the camera and then start video recording. If focus is triggered by shutter release, it's going to refocus when I start recording, and it may refocus on the wrong area - or, if it's a low light situation, it may lose focus because there's no contrasty element in the focus box.

I see a lot of folks complaining about Panasonic's continuous AF for video, which is why I mention it in these threads. Folks need to know that, for video, it's not going to be 100% reliable.
