Cellphone cameras are good, but not great at taking pictures of objects in a distance. I live in a flight path for a landing approach of an airport. Planes get low enough where I can sometimes read writing on them, but taking clear pictures of them with my iPhone 11 is still not great.

A year or two ago the President came to my city and leading up to and on the day of his visit there were V-22 Ospreys flying this path regularly. Seeing it in person was very cool, but the pictures I took look like I caught a picture of a neighborhoods kid toy helicopter from 100 yards away; tons of noise, artifacting, and lost detail.

It's simple, far away objects are hard to video even with modern tech to untrained people. You can zoom in on your iPhone now but holding a steady position would be hard and still even with the zoom the level of detail wouldn't be great to something in the sky.

This has become quite the meme [1] but that doesn't make it true. We do have indeed very little (arguably no) evidence for extraterrestrial UFOs but we do have high-quality data on UFOs in general.

Most of them are explained by simple physical phenomena. Some of them, however, actually do relate to unexplained phenomena or projects by state level actors.

The same reason loud speakers in trains and airports sound like loudspeakers were just invented five years ago.

CCTV material of criminals is similarly atrocious.

+ zhe objects are far away.

Because videos of good quality quickly go from UFO to IFO and only the worst are left. Wheat from the chaff.

I'm guessing it's because it comes from lipstick cameras inside the cockpit, recorded on an analog VCR behind the pilot's seat.
