Looks like CG to me.
Interesting, the table and room look like cgi. The Bruce Lee figure, and the other one, move more like cgi with motion capture, but he shows the figures with the boxes at the end. Lots of camera moves jerking in and out in imitation of beginners stop motion, but I'm sure it's added in post. Could be done by animating the figures against greenscreen, and adding motion blur to stop motion is perfectly do-able now, so it could be stop mo. If so, it's impressive, you would have to video some live action and use that as a guide.
Or it could be a computer model based on the figure, animated purely in cgi. I can't see the kinds of folds in the cloth, or the occasional twitch of the fabric, that I would expect with a 1:6 figure.
The second one (Carmine) looks like all cgi to me - very good detailed render of the kitchen benchtop and everything, but I'm not quite convinced. And again, the figure looks like motion capture moves, not animation. So it's leading me to think it's all cgi with no real action figures anywhere.
I'm very tempted to say 'it's a man in a suit'. The movement of all the characters is very realistic as are the shadows.
Look closely at the Bruce Lee character and the elbow joints might just be tape round the human arms. The rest of the torso may be a foam jacket to give the effect of the shoulder joints.
The other two characters are easy to create as a costume for a real person. With a green screen, the right lighting, the right software and no small amount of skill those shots can be composited with the backgrounds to produce these very convincing results.
Even in these hi-tech days, some of the characters we see on the screen are still portrayed by real actors!
Now prove me wrong
The immediate tip-offs to my eye in the first shot were:
The setting itself might be a real image; it's too low res to tell, but its lighting is much more natural than Bruce's.
For the second shot:
They probably took 3d scans of the action figures and built CG models of them. The movement definitely looks like motion capture, and if you watch the feet they slide around weirdly on the table at times, definite sign of compositing.
A bit of searching on 'John Beswick' reveals the following:

Unfortunately the link is broken. Wikipedia has a rather long explanation of the term 'machinima' but it basically means using software originally designed for games to generate characters and their movements outside the normal game environment.
Nice find Sir Kit! I'll bet that's exactly how it was done.
If you look at this video by the same person, it's clearly footage of a character captured from the computer game "Gears of War", then rotoscoped into live video: https://www.youtube.com/watch?v=1sYK5yZOgGc
That explains how the kitchen bench scene was made.
The video with the action figures -- it might include some stop-mo. It could have been made with a clean plate photo of a real-world background/table/props, and rotoscoped stop-mo figures that were animated separately based on a video reference. The reflection of the glass in the background doesn't change, which suggests it's a still photo, and all the camera moves and shake are added in post. The very low video resolution is probably a result of cropping most of the frame during digital camera moves (also means you can't scrutinise details in the video).
Interesting to compare with these videos, which really are stop-motion animation:
