Seems this sketch with Ben Kingsley has been filmed at 30fps with the studio and intro at 25fps. Reminds me of when Carpool Karaoke was on Comic Relief and had motion judder issues.
The studio production is 59.94i
Since the move to HD, it's been a LOT easier to make shows in different frame-rates in Europe - as the image format remains the same (1920x1080 or 1280x720 - though the latter is rare outside North America - as in Europe 720p broadcasters usually run 1080i in studios and OBs)
As a result the same cameras, switchers, VTRs, CGs etc. all can now usually easily switch. It's less common in the US to be able to run at 50i, because so many displays sold in North America won't lock to 50Hz (whereas 59.94Hz compatibility is universal in Europe), so European shows made in the US usually have to shoot 59.94i and standards convert to 50i - unless they take their own flyaway gear.
(Believe it or not some
TVC Studios were supposed to be 525/625 switchable in B&W - which was easier with tubed cameras than CCDs - but this was non-trivial and I'm not sure it happened in anger. Some ITV companies shot the same shows in parallel on two different sets of gear to record both a UK and US version ISTR)
