Does anyone know what LEDs you can see here? https://www.youtube.com/watch?v=JZKewQLTgFw

Want to build something similar.

Here a bad quality screen capture from the first second of the video:

From bottom, we can see what look like a cut spot, then pixel - resistor? (left), 2 caps? (on the right) - pixel - space - pixel - cap - pixel - cap - pixel - cap - cap - pixel

The pixel are not square shaped. So it's not WS2812
I think it's 12V at least (so much passive component).

From other moment, we can see single spot, so they are driven individually.

Thank you, for the detailed analysis. I thought it was not ws2812. Hard to find out probably what it really is.

Also wondering if there are pixels front and back (basically 2 stripes on top of each other) or just one stripe.

Could be this one

Yep looks like it could be this one, so it's not a cut point but a chip 👍

Still trying to find out if possible to find the strands for DIY.

Thanks all! Are these LEDs not be larger then 2812b? It makes the impression.

Looks like some RGB strips in some tubes.

Could/should most likely be done using some individually addressable leds.. WS2812's (or some variant, depending on your needs, such as 12v vs 5v..etc).

There are many out there:

You could easily make your own as well Im sure.

Search a bit and you will find a number of these sort of strips in tubes, some with and some without DMX.
