How to connect eight WS2812B LED strips to one Arduino?

Question

Arduino

There was a need to connect 8 addressable LED strips (WS2812B) to one Arduino.
Tapes with a capacity of 9 to 15 LEDs. The Arduino has 6 PWM outputs, but it turns out that you need 8.
At first I thought to parallelize the signals - some tapes are of the same length. But it didn’t work out just to separate the cable into two tapes - it seems that there is not enough power and the LEDs on the tapes are not weakly stormy.
I thought about shift registers like 74hc595, but I have no idea how it will work, for example, with the Adafruit_Neopixel library, where the pin number is simply indicated on the input.
In general, it is permissible to connect all 8 tapes into one and connect to one pin, but a cable half a meter long will be laid between each (the bottom line is - imagine a star with a diameter of half a meter, tapes will be laid at its ends). I'm afraid that the singal will be lost with distance.
Please suggest the smartest way to do this.

Answer 1

It is possible through shift registers, and further without a library.
It is possible in parallel and through a mosfet - so that the signal is not lost with distance.

Answer 2

Can be via charlieplexing / multiplexing / goreboplexing or via Binary Angle Modulation
