Fixing out-of-sync audio in the timeline

- [Speaker] So far, we've mostly been dealing with married video and audio, which means they come as a pair. When you move or edit one, the other goes with it; however, we've also talked about ways that you can separate your video from your audio, like if you turn off the link selection toggle. Then, every element in the timeline is independent. Or, even if you have the link selection toggle enabled, you can option click, or alt click on a PC on any element in the timeline and then it becomes independent, and as you can see, you quickly get out of sync.

If you notice it right away, not a problem, just command Z or control Z, and you're back in sync, but sometimes you're working, and you notice that things are out of sync, and you can't really undo it very easily. Fortunately, there's some really great built-in ways to fix this in Premiere Pro. Let's take a look here. I'm going to zoom in, and you can already tell that we're five frames out of sync. I'm going to play it so you can see what five frames out of sync looks like - Quality, we source the highest quality ingredients. - [Speaker] Again, this is a very easy fix. All you need to do is right click on the out of sync indicator, and you choose move into sync.

Alright, and so it's immediately fixed, and I'll go ahead and play it. - Quality, we source the highest quality ingredients. - [Speaker] I'm going to undo that, command Z, because I also want to show you that if you right-click on the audio, then the audio is going to go join the video. Alright, so you just noticed that the video joined the audio. This is the opposite. I'm going to right-click and choose move into sync and now the audio went to the left, earlier in time to join the video. In this case, that's not what we want. We wanted to actually have the video join the audio so that Jack's soundbite is flush up against his other soundbites to the right, so I'll undo and then move into sync like so, but I just wanted to mention that because sometimes, you're going to need to do it the other way around.

Now, there are some cases, however, when you're out of sync clip is butting another clip, so you can't actually move it in the way that we did here when we had a few frames of room. In this one right here, if I was to move into sync, watch what happens. I will right click and choose move into sync. It's moved it over so that things are synced up, but it overwrote the clip to the right and separated from the clip on the left and that's not what we want. I'm going to undo, and instead I'm going to choose the other option that's available. I'll right click and choose slip into sync. You'll notice that the clip is left right where it was.

The video was slipped in order to match the audio. We talked all about slip edits in chapter five, and that's exactly what's happened here. It's reached to an earlier or later point in time within the video so that it matches the audio. When you have a clip that's butting other clips, that's the command that you want to use. We should be in sync now. - About the beer. And the beer only. It's not really about the. - [Speaker] I don't think I showed you what 11 frames out of sync looks like, so let me undo that and I'll show you. - About the beer. And the beer only. It's not really. - [Speaker] Alright, so definitely a problem, but couldn't be easier to slip that back into sync.

Alright, so that's move into sync and slip into sync. Most of the time, one or the other of those will get the job done, and with both of these, there is a very visible indicator that there is a sync problem with those little red boxes in the number in the corner; however, sometimes there is no little red box. Let me come to this example here. I'm going to play it for you. - Extremely talented, extremely passionate people. - [Speaker] Alright, so there's no out of sync indicator, but this is still definitely out of sync, and this can happen when you unlink your clips.

Either purposefully or accidentally. Right now, these clips are unlinked. I can select video and not audio and vice versa, and of course there's no indication that they are even supposed to be linked together, but they are, and to link them back together, you simply select both of them, and you can either right-click and choose link, and there are our out of sync indicators, or the keyboard shortcut is command L, or control L on a PC. If I press command L, I'm unlinked, and if I press command L again, I'm linked.

Most likely, you've accidentally command or control L and you find yourself in this situation. If you catch it, you can always just link it back up, or I want to show you that there is a preference under Premiere Pro, preferences, and timeline. You can display out of sync indicators for unlinked clips. If you check that and say okay, notice that I get my out of sync indicators back, and I think, on this one, I'm actually going to want to sync the audio to the video so that we're flush up against the other clip.

I'm just going to right click and choose move into sync, and we're in good shape. - Extremely talented, extremely passionate people. - [Speaker] Again, getting out sync will certainly happen to you at some point, but it's pretty easy to get everything back into sync and keep working without any problems.
