From my simple point of view, the 8K shooting on Note 20 Ultra is probably more like a commercial gimmick or something you could show off on your phone rather to have some real practical use. It might be useful if you apply a gimble (eg osmo mobile) to stabilise the footage as while shooting in 8K, the stabilisation is really very basic and limited. Also the Zooming, tracking auto-focus and some other stuff are not available in the 8K, either, make the 4K more practical to produce something useful (this is also considering that 8K video is not very widely watched for now). No mention the 24 fps Vs. 60 fps, that limit some of your post-editing space.
