The past Fall, a purple ethereal object hovered at the edge of my property and hung out there for a pretty little while.
The video of this object in the youtube link below, makes it seem like it is a purple bird perched on the fence. It is not a bird and it was not
tangible. It was a ball of purple light in the middle of the day. It looks like it has a white or silver tip.
If you have thoughts about what the purple light is, I look forward to hearing them.
I can't think of anything it could be except a video
compression artifact. I've seen them occur before in high contrast areas, and where you see it is on top of the whitest part of the white line.
About 2 years ago, I downloaded a James Bond Medley video from youtube, and they were using a compression algorithm that produced purple artifacts in
high contrast areas. The performers were wearing white coats and black shirts, which of course black versus white creates the highest contrast
possible. They don't occur everywhere that black meets white or high contrast areas, just in odd little spots or sections. See the purple thing in
this screenshot on top of the performer's nose?
That's a video compression artifact, no doubt. And it's where the white coat and black shirt of the performer in the background meet. It's more well
defined than yours but they are intangible as you say. Four seconds later, as the camera zooms out, you can no longer see the compression artifact
above the performer's nose, but instead you can see some spurious purple compression artifacts in the upper right corner.
Youtube is always monkeying around with their video and compression formats. The video I downloaded two years ago used an older compression algorithm
that produced the purple artifacts. Now when I download the same video, the compression algorithm is more modern and advanced, so the purple artifacts
So one thing you can try if you see purple artifacts is try photographing the same scene with different models/makes of cameras/phones, which may have
different compression algorithms. Then you might see the purple artifact show up in some cameras but not others. I think the compression artifact
explains everything you described.
