exporting a video. i've done this so many times and now i can't remember how to. i tried apple shift e at first like you do with photos but that didn't work and i can't find any options when opening it in quicktime that will let me compress the file. you know how you're supposed to be able to open a window which will let you choose if you want it to be for web streaming or other stuff. I CAN'T FIND IT. WHAT AM I DOING WRONG?
