Sometimes you may be working with footage that doesn't contain the best audio. Perhaps, an interview was recorded with an onboard camera mic, but perhaps good quality audio was recorded separately. This is a very common workflow. Fortunately, in Final Cut Pro X, you can quite easily marry a video clip containing poor audio with an audio clip of higher quality. Let's take a look at how. So, in my Farm to Table event, I have a keyword collection called Audio Sync, and I have a clip of BD here. And if I play it, you can tell that it doesn't have the best audio.
(BD Dautch: And that's why the farm that I have is kind of designed like a garden, it's--) I do have much cleaner audio here which I'll play for you as well. (BD Dautch: The farm that I have is kind of designed like a garden. It's very diverse--) Now, what I am about to show you only works if you actually recorded audio of some sort on the clip with the poor audio. The reason is that the built-in synching feature actually matches the shape of the waveform between the clip with the poor audio and the clip with the good audio.
So, all I need to do is select both of these and then right-click and choose Synchronize Clips, or Option+Command+G. Now, it looks like nothing happened, but that's because I am in my Audio Sync keyword collection. If I pop back out to the main event, you can see that this is my clip that has now been created. You can just drag that into the Audio Sync keyword collection if you like. This clip contains both the bad audio and the good audio.
Click on the clip and then open the Inspector, Command+4. And I'm on the Audio tab, let's go down to Channel Configuration, and you can see that I have two configurations here, Storyline and Connected. I'm going to play each one of these. Let's go ahead and select just Storyline and play. (BD Dautch: And that's why the farm that I have is kind of designed--) All right, so that's the bad audio. And then I will select this one here and play again. (BD Dautch: And that's why the farm that I have is kind of designed like a garden--) So, if you want, you can just uncheck the one that you don't want, edit it in and then leave it attached to the clip.
If, however, you actually want to delete the bad audio once you edit it into the timeline, you can. I have an empty sequence here, 6.6, and let's go ahead and just edit this whole thing into the timeline, I'll just press W, okay? And right now this contains both the bad and the good. But let's go ahead and delete the bad. So what I'm going to do is click on the clip and then go up to Clip and Break Apart Clip Items. This is the video, this is the bad audio, and this is the good audio.
I need to detach the bad audio from the video. So I'm just going to click on it, right-click, and Detach Audio. And so now, this is the bad audio, I can go ahead and just delete it. Now, we can go ahead and play it. (BD Dautch: And that's why the farm that I have is kind of designed like a garden--) Everything is sounding good. So, as you can see, synching audio is a relatively quick process, especially because this functionality is built into the software, so there is no need to go to a third party to do the job.
