In my youtube quality menu, it only goes up to 1080p.

Is this really 4K?

I don’t know if it was a specific mission requirement to give the rover a camera that conveniently functions as a selfie stick, it’s pretty damn genius and gives the photos a lot of context and character.

Goes up to 4K for me, are you on mobile?

For me, it lets me choose both 2160p(4K), 1440p(HD), and 1080p(HD).

I'm not sure if panning through static photos Ken Burns-style from Mars qualifies as "Mars in 4K [video]". But I appreciate that it makes these stunning images more accessible to more people.

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.

I have a 4K option in the youtube menu.

At one point in the video, there is a 1.8 million pixel image where they discuss and show zooming into the image while preserving detail.

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!
