I followed all of the tutorials, and I still can't figure out how to change the black background to whatever I want, how is this achieved?

You dont so much 'change' the black background, you must have loaded your greenscreen clip and removed the Green, leaving your black canvas in the background in place of the green.

Your green screen clip will be there sitting on the timeline - To have a background of your choice showing you now will have to load an image/video into your project, just like you did with your green screen clip and drop that on the timeline too. Once there, drag this 'Background' clip so it's below/under your greenscreen clip on the timeline.

The black background you are seeing is just the 'canvas colour' that is always there, by default it's black but can be changed to any colour. One useful thing i do is to change this colour to white when im green screen keying 'IF' my subject is dark coloured. This means that when i start keying out the green it will progressivly turn whiter - As my charactor is darker coloured, if i key too much then i will see white blobs appearing on my charactor because the white background colour is showing through - In this situation, if my 'Canvas' colour was black i would'nt reolise that i was beginning to key out my charactor too.

Use this canvas colour to help you with your keying, pick a colour that contrasts strongly with the colouring of you subject, it can really be helpful.

Good Luck
