In this movie, we're going to look at editing video to music. A lot of times, this comes in handy as the example we are going to see here. When you're editing music to a music video, and then like maybe when you're capturing the footage, or when you're shooting the footage, the artist were just kind of lip-syncing and you got to use the high quality audio to kind of sync them, both the audio and the video here in the timeline. These techniques might also come in handy when you're working in certain workflows where the video and the audio were captured separately, say for example, in the case of film. So there are a couple of great rules to keep in mind.
First of all, the audio file here, the audio waveform in the timeline is your best friend. So you want to click this little down arrow and make sure that we can see this waveform because this waveform tells us a lot about what's going on. If you need to, you can hit the Plus key on your keyboard to zoom in a little bit and see the waveform better and you can zoom in really, really closely so you can see the little minute details of the audio waveform, but we don't want to get in that closely. So it's kind of good. I like this view right here where we could kind of see the peaks. These are called transient. When there is like little spike that goes up, it's referred to as a transient, and then the spots where there is flatness, and the flatness means that there is no audio there.
So if you're editing a video of someone talking, you can actually see the flat lines, as you can in the first few frames of this audio clip here, where there is just a flat line, it means there is no dialog, no audio going on there. And again, the transients I was referring to earlier, this little spikes right here, this, right in the edge of the waveform where it's kind of peaking a little bit. You can use those to line up, like let's say somebody is about to say something and visually, you can see that they're about to say it, maybe they're, like, have a hard consonant, like an F or T, then you can line up the transient with that frame of video.
Now another great tip is to use the Sample Rate for precise editing, for when you're trying to align audio to video. We'll talk about that in the next movies. It's kind of its own topic. But another important aspect of this is to go the Preferences. On a PC, it'll be under the Edit menu. Under Mac's, it'll be under the Premiere Pro menu, go to Preferences. Let's go to General. And actually the option that we want, once we open up Preferences, it doesn't matter where we start from, we can go to Audio here and what we want is Play audio while scrubbing.
This can really help us while we are aligning audio, as we'll see in just a second. So I am going to go ahead and check that and click OK. Now that option basically means that as we're dragging the Playhead here, we can hear the audio play back. What's really cool about that is that the video and audio both play back while you're scrubbing. So you could see, in more detail, how aligned or how in sync your audio and video are. Now we have kind of a simple example here, just for the sake of easiness, I want to show you a few little tips here.
What we're going to do is we're going to play back and listen to when the singing starts and when the rapping starts. Okay, so right about here. Okay, so you can almost visually see there is a little dip right before they start rapping, right about there. And this video clip starts about when they rap, so we can just drag that to there and let's just see, kind of randomly, how that works out. (Video playing) Okay, that's kind of hard to see when you're playing back.
So let's go back and we'll scrub and maybe get a better idea, as we're listening to this slowly and watching every frame, how well this is in sync. I actually think that looks pretty good, especially as he says Time, the second time, the T and the M both look like they are in sync.
So for just a random shot out of the gate, we did pretty good here. If we did need to do some fine-tuning and we didn't want to use the Sample Rate, again, that we'll talk about in the next movie. One of the things that I like to do is trim a little bit off at the beginning, if that's possible, and a little bit off the end, and then use, again, the Slip Edit tool, so we can just kind of get in there and just tweak a frame or two in any given direction, so if it's a little bit early or a little bit late, we can just kind of click-and-drag left, to back this up a couple of frames, or click-and-drag to the right to advance it a couple of frames or one frame, if the case calls for it.
So, in a nutshell, those are my three quick tips for editing video to audio. Number one, make sure you are not only viewing the audio waveform by expanding the arrow here, but you're also using it as a guide for aligning audio in a rough sense. Tip number two, use the audio sample rate, which we'll talk about next, and number three, use audio scrubbing. Enable that, while you're editing, so that you can just do a quick check to make sure that you've got the audio and video in sync.
