In my youtube quality menu, it only goes up to 1080p. Is this really 4K?

I downloaded it with youtube-dl because I cannot stand the excessive adverts on Youtube these days. During the download it grabbed this video file:

  Input #0, matroska,webm, from 'New - Mars In 4K-ZEyAs3NWH4A.f313.webm.part':
  Metadata:
    encoder         : google/video-file
  Duration: 00:10:08.41, start: 0.000000, bitrate: 4436 kb/s

So yes it's 4K.

Mine goes up to "2160p" but since the source photos are stitched together, I'm not sure what their total resolution would be (probably varies based on what/how many were stitched together).

It's basically some pans across high resolution composite images. Quite cool but not captured video. As they mention, there's not much moving there anyway but it will be cool when someday we can look at high def (or even stereoscopic) video from these remote locations.

The narrator explains why getting HD video would be impractical, but I disagree that we get the same experience from panning stills.

imagine seeing the swirling dust, shifting sands, the bumps and parallax from a moving rover. that would be so cool!
