![]() The second is you want to separate the lavalier and the boom into their own individual channels, so that you can hear the same dialogue out of both ears. The first thing that we want to be able to do with this particular clip is fix the problem that’s occurring with the lavalier when Brian smacks it with his hand. It’s intended that you hear different instrumentation on the left ear than you might hear on the right ear, but when it comes to something like dialogue, you would not want that to be the case, as demonstrated here, because we want to be able to do a couple of different things. In this example a stereo track of dialogue was recorded, however music is something that should be stereo. In fact, this is actually a common problem that you may run into while you’re beginning to do work on different projects, especially in the documentary or corporate space where you may be conducting an interview with one boom microphone and one lavalier microphone. It’s not ideal that you can hear the lavalier out of your left ear and the boom out of your right ear. In this example, what happened is that the boom microphone was plugged into the right channel of Brian’s two channel recorder, and on the left channel of that same recorder was the lavalier microphone. This is a really good demonstration of what a stereo track actually is, It means that the audio on the left side of the track is different from the audio on the right side of the track. If you didn’t hear that, play back the clip again. The lavalier microphone should be on your left ear while the boom microphone should be on your right ear. If you were listening with your headphones, you probably realized that at some point you heard Brian bump the lavalier microphone with his hand while he was discussing it. Let’s figure out what’s going on with the audio here. Listen to the same audio clip below, but this time with some headphones on, because you’re going to hear a very clear difference between the two different audio sources on this clip. Next, you’ll probably want to remove the audio from the camera (blue as in the timeline above), as it doesn’t sound very good compared to the audio track that was recorded using a Zoom H4n Recorder (Green). The Clap at the start of the footage can be used to sync the separately recorded audio Working with Multiple Audio Sources This is a very ‘poor man’s’ way of syncing up the audio, but for our demonstration purposes right now, this is all we need to do. You may have to do a little bit of shuffling around, like moving the video clip over, but now you have the audio lined up to the video recorded. Next, look at the recorded audio visually on the timeline where that clap actually occurs, and you can make an edit point there as well.įinally, you can simply drag the audio along the timeline so that the two edit points line up to each other. If you identify the exact frame that Brian’s hands clap, you can make an edit point right there. ![]() Now listen to the audio that was recorded. In the clip, Brian claps his hands one time. First, let’s go ahead and sync up the audio. So, in our timeline we have the video, the video’s audio track, another audio track recorded separately. Additionally, we also have some audio that he recorded separately for this footage. ![]() Stereo audio clips have 2 waveforms, which means different audio comes out of the left and right speaker How to Sync Audio to Footageįor this example, we have a video clip of our Premiere expert Brian, standing outside, recording on his iPhone. Now if we used a mono track, these would be exactly identical and even. ![]() That’s because in a stereo track, the audio coming out of the left speaker is slightly different than the audio coming out of the right speaker. If you play back a stereo audio clip, do you notice how the left side and the right side of the audio meters are bouncing at different levels? What this means is that the audio is coming out of both the left speaker and the right speaker. In Premiere Pro, if you were to click on any stereo audio clip, it will highlight both the top and the bottom waveform. Mono Audio and Stereo Audio – What’s the Difference? Watch the video or keep scrolling for the written version! This in-depth tutorial for Adobe Premiere Pro will help you understand the proper way to work with your audio. A lot of editors tend to get a bit careless with how they work with mono or stereo audio, and it can have a negative impact on how the final mix ends up sounding when exported. ![]()
