These are shots/clippings from videos that are shot straight from a video camera, and uploaded to a computer/social networking site - it is raw footage that hasn’t been edited. You don’t typically see this in trailers as it is more common to use transitions because they add effect on the trailer.

Fade is a transition where the scene/picture gradually fades, either on to the next scene, or it can fade to a text slide, or to black. This is often used at the end of trailers, to build up tension and to leave the audience on edge and want to see what happens next, so then, they go and see the film.

Cross Fade is a transition where two scenes collide with each other, one scene is still running whilst another one begins. As the first scene ends, the second one begins and cross fades in. Cross fade is often used to change the speed of a scene, because the transition is quick, and fast paced, which adds effect to the trailer.

Wipe is a camera transition that clears the screen, and gradually moves on to the next image/scene. It is a gradual effect that happens slowly which triggers the audience to think about the scene, and what has happened, if the previous scene has been dramatic or emotional it adds emphasis to the previous scene/image. This transition can be made in a number of ways, from left to right, right to left, wipe down, wipe up etc.

Pan and Zoom is a transition where the camera moves, slowly; in different directions and zooms to focus on a person or an object within a scene or photo. It is a slow effect to symbolise calm events taking place. This is a good effect to use when building up to a dramatic scene. The pan and zoom transition is used in many ways, the most common transitions are pan up, down, left, right, pan and rotate.
