I want to use this Creative Commons trailer for a non-commercial work. Specifically I want to compose my own music for a demo reel. 1. Why does the description not mention CC even though it is CC. (I used YT's CC filter to find it) 2. I want to (a) strip all the audio and add my music or (b) rip the same scenes from a DVD so that I can retain the original dialogue without the music from the trailer so I can add my own music. 3. If your are using videos for non-commercial work aren't we protected in the first place? What if I want to use any BMW car commercial or movie trailer or food commercial for tutorial/demo reel purposes? It's non-commercial so what's the issue?
