Tip If you’re not sure where to find the effect or transition you’re looking for, type part of the effect name into the search option at the top of the Effects panel. With interview-based projects such as this one, cutting out parts of a clip can result in jarring jump cuts where there is an obvious break in the video. To smooth over this break you can apply the Morph Cut (Premiere Pro CC 2015 or later) video transition to be consistent with the audio crossfade. You’ll find it in the Video Transitions > Dissolve group in the Effects panel. Previewing transitions You learned about some of the performance considerations involving playback in the sidebar “What to Do If Playback Isn’t Smooth While Editing“ in Chapter 2. You might notice that rendering bars indicating lower performance show up more often over transitions than over a single clip. Why is that? It isn’t hard to play back a single clip; your smartphone can probably do that. When you apply a transition, you’re asking Premiere Pro to play back the two clips involved in the transition plus the transition itself. Because the transition combines the two clips, it doesn’t look like either of the original clips, so Premiere Pro can’t simply read it off your storage. The transition has to be calculated. If Premiere Pro believes the transition might be too complex to render in real time, you’ll see a yellow or red render bar over the transition. You usually don’t need to be too concerned about a yellow render bar. But if the transition isn’t playing back smoothly and you would like it to, select the transition and choose Sequence ¢ Render Selection. This creates a new preview file that Premiere Pro can read directly from storage and quickly display, so the render bar becomes green.
Adding B-Roll Clips ACA Objective 4.4 Video 3.6 Add B-roll Video productions often consist of primary and secondary video footage. For example, in this interview project, the primary video consists of Joe talking, and the secondary video shows Joe snowboarding. Primary video is traditionally referred to as A-roll, and secondary footage is B-roll. The A and B terms came from tape-based video editing bays where you would load tapes into two source video tape decks marked A and B, and assemble them into your sequence on your program video monitor. B-roll is used to help maintain the viewer’s interest with engaging supplementary video or
