I’m the exact opposite. My gut says it’s rendered. The graininess, the odd chromatic aberrations, the shadows that are too clean, the “head” being way too physically clean (like if the modellers got sloppy with the thousands of pieces), something odd about the fps of the robot vs the fos of the background, and there’s something odd about the physics of how it gets up (yes, beyond it’s horror-movie sequence)

It is a bit funny though, the company renowned for walking robots posts a video of a robot walking and many people just can't believe it.

To me it was way more surprising that they got walking (and more) working with hydraulics, a much more unwieldy and heavy technology than servos and batteries. This is obviously more refined but perhaps to me, a little less surprising and so definitely believable.

Even more odd to get a response like this that has certainty without any facts or debate.
