When you insert a video clip in PowerPoint, you may find that the inserted video starts playing abruptly when started within the Slide Show view, causing a jarring interruption to the flow of your slides. Not only can the sudden movement within the video clip area disrupt the flow, but the instant playing of a video clip may appear as a surprise. This sort of disruption can be worse if you have trimmed your video clip. Clearly this is not a very professional or acceptable state of affairs. Fortunately, this is avoidable if you opt to add Fade In and Fade Out effects to the beginning and end of your video clip.
