I'm enjoying your work as well. You should consider using CameraPlus as an aid to movie making. With this mod you can have keybinds to better control camera movement. The config panel offers options to control the speed of camera rotation and zooming. If you slow the rotation speed down to 2 you get a very nice pan effect in your video. You can also write macros utilizing the WoW API to help move the camera leaving your cursor free to click things. Something else you might try for effect is setting up different camera views with Blizzards standard keybindings and then switch views while recording. This causes the camera to sweep from one view to another and provides a nice effect. And there is also Camera Bobbing which moves the camera away from your character.
