There seems to be some rules what footage is shown and i think i have it correct.
1. - if it's not noted otherwise it's always normal 25 GB PC-quality footage.
2. - The Split-Screen footage is PC-quality again because they are using internal testing PC builds that can do everything what console versions have, Split-Screen will just be manually disabled in the shipping PC version.
3. - The "saving, ...turn of console" could also be PC footage because they're using an internal build to record - a playable PC version with console-assets
4. - footage from full-quality ~150 GB internal build has never been shown
It has almost always been PC footage in previous years prior Zenimax aquisition of ID (i hope carmack tried to get ownership percentage in Zenimax
