We are now going to look at the relationship between audio and video. We haven't talked about this too much. By default, video clips that have attached audio to them are attached at the hip. We have the video equivalent and the audio equivalent and as one moves, they both move, and as you trim one, you trim both of them. So, what if we want to split up how we edit the video or the audio? You know it's one of the most powerful editing tricks, as we'll see in just a second, to be able to have the audio come in a little early before we actually get to the person making the audio.
So, what we are going to do here is we are going to click on this first clip and we are going to trim this. But we are going to hold down the Option key on the Mac or the Alt key on the PC, and I am going to trim just a few seconds here. I've probably trimmed a little bit too much, but I am going to drag this other clip in. Now, I realize that we could have done this with an overlay edit, but I wanted you to see how this is done traditionally. Actually, I'll hold down the Alt key and restore that last little bit of audio.
This is referred to as a J-cut. This is when the audio comes in before the video of that clip, and it creates a lot of interest. I am going to marquee select, just click-and-drag around both of these clips and move them to the beginning of the sequence, and I am going to go to the first frame. Now, let's see the initial video while we listen to the audio of the speaker here and see the effect that has. (Female speaker: Welcome to Hansel & Petal. We are a full -service florist, specializing in weddings and corporate events.) Actually that edit doesn't look very good.
There is too much of that first video clip. So, let me hit the Backslash key, so we could see our whole timeline little bit better. I am not able to edit as of right now because I need to click outside these clips to deselect them. I could put my cursor back here and I can trim the last little bit off this clip and then hold the Option key and restore some of that video. But you'll get the effect that this other video clip comes in and the audio of the next clip comes in. So, while we are looking at this really cool floral shop, we are introduced to it by the next clip.
So, it creates interest before we even see her face. (Female speaker: Welcome to Hansel & Petal.) (We are a full-service florist, specializing?) I probably want to fiddle with this until I could get her to say "full-service florist" and then have that video come in when she says "full." But for the time being, you get the idea and the impact that that has. It works really well with documentaries like you are watching like an image of the Civil War and then you hear somebody's voice come in and saying like, "oh, my grandpa says that those were hard times" or whatever, and then you see the person that's actually talking.
It's a way of leading interest. Now, we could also do the same to the end of the clip. We could hold the Alt or Option key and drag the video here and have the video extending while we have another clip going here. This is referred to as an L-cut because it creates kind of like an L shape. Now, if we wanted to, we could also right-click on a clip that has video attached to it and we could choose Unlink. This will unlink the video and the audio. So, as we move one, they will no longer be in sync. So you got to be careful about that, but this will allow you to go in and delete the audio.
So, we have this video clip here of the flowers in the fridge, then we don't really need the audio here. This is just b-roll. So, I could now select this audio and just hit Delete and now I can move this over the end here. I'll hold the Alt key and trim the video a little bit more and I could just bring in this video and actually we could just perform a little Overlay edit here. But now on this L-cut we have her talking while we are looking at flowers in the fridge. (Female speaker: And we do take a lot of pride in that.) Actually that was the end of the clip. There everything else is an outtake. So, I'll move this again a little bit earlier and now we could see what that looks like.
(Female Speaker: Okay.) (Male speaker: ?everything we discussed.) (Female speaker 2: It was like "every design is a one of a kind creation.") Haha. That's actually another outtake. So, I probably should have trimmed the rest of the audio, but again the concept is still there, where we can see footage from something else. We could see b-roll and have the audio from another track continuing to go. Now, again I can't stress enough, if we were to for example click on this clip and hold the Alt key and move this clip, these would be out of sync. And as you could see here, this is saying that we get a +7.02 here and a -7.02 here.
So, as an indicator saying, hey, be careful, because you've actually moved these out of sync 7 seconds and 2 frames. So, if we wanted to restore this we have to again Option+Drag or Alt+Drag this back to its spot to lose that warning. But it's very easy to lose sync with your audio this way. So, again be careful. So, that's basically the trick. Just remember that when you are editing, it's very powerful to be able to hear something that leads you to the next thing that you are seeing.
