For making the picture you will need an LED Driver because there are too many LEDs you can’t control all of them with one Arduino (It is not impossible. But it is very hard to do with Arduino to run a video file through Arduino). So basically people use a proper t300k controller for controlling these LEDs. And it is easy to do.

LM386 is an low voltage, battery operated power amplifier designed for application where low voltage is main concern. The main advantage of using LM386 is it does not requires any ground reference voltage and it’s output is automatically biased to 1/2 of supply voltage.
