Cincinnati media blogger John Kiesewetter did a piece on Scripps' pre-taped autopilot newscasts, particularly WCPO's 4PM shows: https://www.wvxu.org/media/2023-11-01/wcpo-tv-news-shows-scrippscast-tvkiese
So apparently, they're using proprietary technology (!) called "Scrippscast" to do this. To me, it basically just sounds like glorified control room automation that's designed to cut costs and nothing more.
Regarding WCPO, it's just their 4PM newscasts and their weekly FC Cincinnati sports show* using the "Scrippscast" software at the moment, but the article mentions that their Saturday 11PM newscasts will be next to go the mostly-anchorless route. And according to their news director (quoted at the end of the article), possibly more...
*I should also point out that FC Cincinnati Weekly looked more-or-less like a traditional sports chat show, complete with pre-taped packages, last I checked.
