This video explores the process of syncing video and audio clips in the double system recording system. You look at various ways to sync clips, including via in/out points, markers, timecode, and especially by audio. You learn that if audio was recording on the camera, Premiere Pro can match up the shape of the audio waveform in order to automatically sync them together.
- [Instructor] I want to talk about merging video and audio clips together. What I mean is, many times, video and audio are recorded separately during a production in a process often called double system recording. This often offers more flexibility during shooting and is very common, especially with today's DSLR and digital cinema cameras. In Premiere Pro, you're able to merge these clips together in post-production, which allows you to select a video clip and sync it with up to 16 channels of audio. And this process is actually an automatic one as long as you record audio onto your camera, no matter how inferior quality the audio.
Let's take a look at this. All right, so I have a video clip here of Casey. And if you listen, you'll notice that it has pretty bad audio. (Casey talking in video clip) - [Instructor] All right, so that was just captured with the onboard camera mic. Definitely not suitable for our project. Here is an audio clip of superior quality. (Casey talking in audio clip) - [Instructor] All right. So I want to replace the bad audio with the good.
And so fortunately, all I have to do is select both of these clips, right-click, and choose Merge Clips. Here, you can rename it if you want. But the most important part is to choose the synchronization method. Now, what we're going to choose is audio, but I do want to mention that you can reach into each of these clips and set an in point or an out point, or a marker, or, if they have identical time code, you can use that. I'm actually going to cancel this for just a moment. And I'm going to show you a couple of clips that are not in your exercise files, but that I want to show you anyway to talk about that in point, out point, or marker.
Here, for Jack's interview, you can see that there's clap sticks. All right, so the moment that the clap sticks come down could be the moment of sync that you place your in point or your marker. And that same point of sync is visible on the audio wave form for your superior audio. If you don't have clap sticks, lots of times, people just clap. So for example, in this interview, you can see that there are no clap sticks, but that they've still established a point of sync by clapping. (clap) - [Instructor] And then for the audio file of superior quality, again, that's a very easy point of sync for you to match that up against with either an in point or a marker.
However, these are things that we do not have to do in this case, because we had audio recorded to our video clip. So, no matter how poor quality, as long as you recorded any audio to your video clip, matching the audio wave form is going to be what we want to do. So I'm going to select both of those again, and then right-click and choose Merge Clips. And so we're not going to choose any of these options. Instead, we're going to choose Audio. And the way this works is that it allows me to match the shape of the audio wave form in each of these clips.
And then it's going to replace the bad with the good. So I've got audio selected. You want to select the correct audio channel. In our case, both of them are identical, so I'm okay with one. And then down here, you make some other decisions. For example, I can choose to take the time code from just the audio track and this lets me add constant time code to multiple cameras for a single source. Not essential in this case, but I can still leave it checked. And then, this is good. Remove audio from the audio video clip. So it's going to remove the bad audio and then replace the good, so I definitely want to leave that checked.
And I'll say OK. And you can see that it was very quickly created. I'll go ahead and load this into the source monitor. And let's take a listen. (Casey talking in video clip) - [Instructor] All right, and a new clip was created. And this now contains perfect sync between the video and the audio. So as you can see, syncing audio is a really quick and easy process.
