Thank you for your comments. The first 2 minutes is that I show one by one instrumens that I use. This is the beginning of my video editing software after effects because my video was not such a thing before and you would be bored to see it. It took me a while to learn good music to create and even make good videos. I like your comments and I'll make sure that after this the music is also a video that further improves the quality of being shared.
