How do I make a Video like this?

I have been just using my iPhone, but i don't get this kind of sound quality. What are the tools I need to make a video like this?

You'll need:
1 computer, equipped with recording software and a sound card
1 amplifier capable of an aux out/usb out/headphone out
software for editing sound and video, so you can blend the original and the bass recording with a video.
Record your bass while listening to the track, while also recording video.
Place your video in your editing software, line up your bass track, line up your song, export, upload.
Voila!

I did an instrumental cover of a song in 2013, and learned this stuff the hard way. Well, part of it at least. Cameras are no good for audio recording!
