Importing a movie

Hello everyone, first post ever.
I’ve downloaded the trial, and i want to make an animation over a video.
I do have the video in quikctime MOV, but when i go to file, import, movie, I choose the movie i want, but it seems like nothing happens?
Any suggestions? I’ve watched tutorials, and every time, a window pops up, not on my screen though…
Should i try something different than mov? if so, which one? Thanks.

Do you have QuickTime installed ?
