The animations are part of the the imaging process.
The data is recorded in 3D and recreated using computers the way a Pet scan does.
I had a pet scan done while I had a migraine and the image was typical for anyone having a sever migraine. However what we were looking at was brain cell activity not physical structures even though those were also revealed by the activity imaging.
The line between computer graphics and microscopes no longer exist, it's a good day.

@Willow_Wisp No some of the animations are clearly artistic recreations such as the picture of a virus.

@Fernapple I'll watch it again, but honestly I may not know even if I do see it. I've seen some seriously intense imaging of my own brain that looked exactly like animation, but it was verifiably not animation.

@Fernapple I saw the Covid-19 animation that was slipped into the video. It seems to be the only one unless they can get higher magnifications then I thought they could get. I was under the impression viruses could only be imaged by scanning tunneling microscopes or the older electron microscopes but electron microscopes suck in comparison. I haven't kept up with current microscope technology, it's why I posted the video, they've come further than I realized. However I'm pretty sure everything else is from this new imaging technique and possibly the Covid-19 but that would be a tremendous leap ahead.

@Willow_Wisp Yes I have sen the old scanning images too. It sounds like they have not yet attempted viruses, they wouldbe very fast moving relative to their size in the free state.
