In this chapter, we're going to look at working with the audio from video projects. Maybe you need to adjust some dialog in a movie or get rid of an unwanted noise in a video interview, or maybe just want to add some background music to an existing file. Audition can do all of that and more. Now there are a couple of ways of getting a movie into Audition, including importing it in from a Premiere Pro project, which we'll look at how to do a little bit later. For this example, let's take a look at working with a stand-alone movie file. On my Desktop I have a folder called Farm Project, and inside it there's a movie called farm_project_intro.mp4.
I'm going to drag that into Audition's Files panel. Now we've seen this before, but just to review, when you drag a video file into Audition it splits the audio and video portions of the movie up. Notice we have an MP4 file and the audio file. Now remember Audition has no video editing capabilities. The only thing the video track is used for is so you can watch it while you're working on your audio, which is useful and necessary if you're designing a soundscape to sync up with what's going on in the video. For example, adding sound effects or music to key points in the video.
Now if I just wanted to edit the audio I can double-click it, and it opens in the Waveform Editor. And from this point I can start editing this waveform like any other audio file. But I can't double-click the video to do anything with it. Again, I'm told that this is only a video and it can't be edited. Now to view the video, I have to put it into a Multitrack Session. So if I want to edit my audio while keeping an eye on the video, I need to switch to the Multitrack Editor. I'll call this Farm Project 01. Keep it saved to the Desktop, I won't use a template for this. And since I'm working with video, this will be a 48K sample rate, we'll leave the Bit Depth and the Master the way they are, and I'll click OK.
So now I'm looking at my Multitrack Session. I'm going to drag the video file onto Track 1. It's not really going to go on to Track 1, but dragging here tells Audition that I want to create a video track, and when I release my mouse you can see that it creates a video track above the audio tracks. I could have also gone to the Multitrack menu to track and chosen Add Video Track from here and then drag my video onto it. Now this option is currently grayed out because I already have a video track open and you can only have one video track in your Multitrack Session. All right, I'm going to drag the audio on to Track 1.
Now I probably want to make sure my Video panel is nice and large. Better yet I can go to the Workspace menu and switch to the Edit Audio to Video Workspace. Now if I had a Dual Monitor setup, I would probably drag the Video panel onto my second monitor so I could see the video at a larger size, but this is fine for my single monitor setup. And I'll go ahead and play a bit of this. So obviously no audio yet.
(male speaker: My name is BD Dautch, and I have Earthtrine farm, where we've been since 1998. And we've got about 10 acres in Ojai, and it's all certified organic by CCOF. And we grow about a hundred different herbs, vegetables, flowers, fruits, and we sell mostly at the farmer's market.) Okay, so you can see that the audio and video are still perfectly synced up even though they are on separate tracks. So at this point I'm free to work on this project like any other Multitrack Session.
Maybe I want to add some compression to this track. Let's go to the Single-Band Compressor, maybe I will choose the Voice Leveler and let's give that a listen... (male speaker: And also we sell to caterers, schools, restaurants--) Bump up the output a little bit. (male speaker: We try to keep it all local.) All right! And since this is the Multitrack file, I can record or input other audio tracks as well. Now there's a lot of silence here at the beginning of the session. I have a track with some ambient sounds I could bring in.
Go back out to the Farm Project Folder here, and there's a file here called background_audio.wav. I'm just going to drag that right on to Track 2 of my project. Now I'm being told that the Sample Rate of this file doesn't match the Sample Rate of the session and if I click OK, Audition will create a copy of that file, which will then be conformed to match the sample rate. So basically it's just going to convert the sample rate of this file, which is fine. I'll click OK. So there is my background audio file, and now let's listen to the beginning... (video playing) (male speaker: My name is BD Dautch--) All right! So that fills it in a little bit better.
Now because of the compression, I'm hearing a little bit of noise crop up right before the dialog starts. So I'm going to trim the clip a little before the dialog starts. Again, we can just do that by dragging in, zooming on that a little bit more, and I am just going to add a slight fade here at the beginning. Listen to that... (male speaker: My name is BD Dautch--) Yeah, that works better for me. Now because Audition doesn't edit or export video, I can't save my movie from here. I can only export the audio.
So I'll choose File > Export > Multitrack Mixdown, and then choose to export the Entire Session. I'll change this to the WAV format so there's no compression applied. It will be saved to my Desktop, file Name is Farm Project 01_mixdown.wav. Leave all the other settings the way they are and click OK. So now on my Desktop I have the Mixdown WAV file. I can open that with any application that plays audio. Let's listen to it... (video playing) (male speaker: My name is BD Dautch, and I--) To sync this back with my video, I have to open that video in my original video editing application--or any other video editing application for that matter--and then bring this audio in to replace the original audio.
So Audition's role in this was to give me the freedom and power to do anything I needed to do with the audio and then export that audio file. I have to turn to another application to put this new audio into the original video. But as you have now seen, it's really simple to open and work with the video in Audition. In the upcoming movie, we'll take a look at how to export a project directly from Adobe Premiere Pro into Audition.
