Right. The team behind this is being a bit dicey with the truth. They never seem to be clear which parts are CG and which are video. Any time Keanu looks goofy, that's CG. It looks hand-animated to me because the movement is so terribly poor. Mo-cap to me is still shitty (see e.g. Thanos in Avengers), but hand-animated is always uncanny.

The article seems to suggest that's all real-time rendering though?

Even the scene from the original Matrix shown on the TV?

This is the actual movie 'wake up neo' scene: https://www.youtube.com/watch?v=sjoad6gcRzs

I’m talking about what’s shown on the CRT TV in the white room.
