It's difficult to determine which is the best quality. You can download all
the file and look in property details as shown here (this is from a GoPro). The
higher the values, the better the quality theoretically. Now, I have seen some
1080 videos that look just as good as 4K on my 4K, HDR monitor, so you really
got to look at them and see what looks best on a large screen. The video you
picked is black and white, low res to begin with. It depends a lot on the
equipment they used to convert the video, I think your video may have been
shown on a wall and rerecorded, leading to possible focus problems.

Hello,
On the internet archive, (the site is legal from what I've read), you can
watch videos. They often allow you to see them in several formats.
So the question came to me, which is the most lossless?
I could find this out from the quantization, or possibly comparing the
two if such metadata were unavailable and analysis of one video did not
produce definitive results.
Here's an example:
https://archive.org/details/Robin_Hood_10_The_Ordeal
It's encoded with h.264, mpeg4, and ogg video.
Does anyone know how to determine the quantization of 2 video files?
Thanks!
