LOL, the vector technique is now old fashioned XD
well for traditional animation I use a graphics tablet and a few free paint software.
Now the video looks nice but what you're doing here is not traditional animation, and nor is it technically 2d, you could say it is mimicking the traditional 2d ways, but I would not say it is 2d traditional.
Reasons why? Well one, it was made with three dimensions. Now that one gets tricky because a dimension can represent just about anything, but traditional animation is the process of drawing, or producing each frame by hand. Here you are giving the computer parameters through the software which interprets those into machine code blah blah, insert some stuff here about os'es and assembly code, and bam the computer returns those parameters into rendered images which puts the pieces together and forms an animation.
Sorry if that's hard to read, I'm a little sick still and tired on top of that.
