Help with image
I bought an video image from istock video. It’s a white door on a gray background that zooms forward and eventually zooms into the keyhole in the door. My problem is that it’s imported as a quicktime file and I’d like to remove all the gray around the door so I can have this door zoom forward to through the key hole with a black background.
What’s the best way of accomplishing this? Is there a key I can use? A filter? Do I need to crop out the gray and build keyframes? What’s the best method and how would I do this? Thanks
