We created a Preliminary Sequence to get used to all the different shots and them edit them together so we are not oblivisious to them all when we come to our our Opening to a film. I feel it has helped us a lot because we had the chance to practice some so we knew what we were doing. We have used various different shots and camera movements to make it look effective, and this is what we have out with. The shots we have used is: Zoom panning shot, Worms eye view, OTS shot and many more.
For Example we did a match on action shot in our Preliminary video and we also used it in our real opening sequence. If we didn't test it out before we probably wouldn't of done it very well in the real thing this is why it was helpful to test it out before.
