It’s pretty clear from the cadence of the questions and answers that they were not recorded at the same time. The spots where the two speakers overlap sound forced and pre-planned. Keighley’s performance sounds pretty off to me, too. The delivery’s all wrong, doesn’t match his interview style.

Some of that could be explained away by it being edited for a short television segment, which can cause some awkward edit points, but… they’re usually better about that sort of stuff.

And yeah, that whole thing looks like a goofy bit of performance capture to me.
