yeah i would have thought that was pretty standard - thats why you hear a lot of hip hop in the films coz they got heaps of mad beats to time with landings and stuff..
and you havent noticed that anything with a soundtrack is edited to the music?
omg.
its really not that hard, takes a long time and alot of finesse, but by altering speed of clips, adding in lifestyle shots and stuff you can get everything to click together.
^in the shanghai six trailor they change the song. its the part when vanular does that black urban rail with all the little drops on it. in the real song this sound i repeated 4 times but in hte trailor it is 5. i hate that part everytime i watch it
