Found Creative Commons Videos, what can I do with them?

[just Moto]

I found the following videos by 404films searching the creative commons... https://www.youtube.com/results?search_query=Four+OhFOur,+creativecommons

I'd really appreciate any advice on what I can use these videos for/how they can be remixed and weather or not the end product can be monetized if I use royalty free music.

Thanks very much
