So that's looking at audio in the Source Monitor. We are looking at Source Channel Mapping to change the attributes of that, toggling between those two tracks in the Source Monitor, and now lets pull in a video clip that has audio as well to round out how to work with video in the Source Monitor.
Let's go ahead and double-click on 13EG_TK01. Now when you open an audio/video in the Source Monitor you are going to notice that the icon on the bottom right corner of this section over here updates to show video and audio. One of the cool things is that if you open a clip that has mixed audio and video like this, if you just want to edit with only the video of the clip you can click this button so that it displays only the video icon. Now then if you were to drag the clip into the sequence, notice that it only brings the video down with it. There is no audio attached.
I am going to press Ctrl+Z to Undo that. And then notice if I click it again, and it shows only the audio icon, here I can see the audio waveform information, and if I edit with it, and drop it on to Audio 1, it edits down that clip on to Audio 1. So if you want to break a clip up, separating the audio and video, you can click on the Toggle Take Audio and Video. Additionally, if you wanted to scrub to an exact point in the video but weren't sure what existed in the audio frame so let's do that right now. If you click on the Jog Shuttle and drag forward. So let's say we want to find the exact moment that the slate hits. Well, it actually hits in the sound, so it's actually hitting in a sample that's between frames.
So if I was to go turn off Take Video just temporarily, and set it to Take Audio, then I go ahead and change the display into Audio Units, and I zoom in, here I can get exactly, to the exact In point of the file. Then I can mark In, so that's where my In point is. It's actually making an In point on a video frame. Then I can go back, turn off Audio Units, click back to Audio and Video, and I have made the proper In point to my clip that's closest to the audio.
I am going to go ahead and zoom this back out, let's go ahead and pick a unique In and Out point in this clip to learn how you can do J and L cuts using the Source Monitor. So let's just capture one moment here. Go ahead and click the Blue Time Code value to the left, enter 0900, that snaps us to exactly 9 seconds into the clip. Go ahead and mark an In point, then go ahead and play the clip, and while the clip plays back, let's go ahead and press the O key about at 25 seconds.
Now notice that when you press the O key while it's playing back, the Out point dynamically adds itself to the clip, so if you are watching something you can clearly press the I key while you are watching it then the O key and you have made an In and Out point specifically relating to what you clicked while you were watching the clip.
With this In and Out point selected, as we learned earlier with video only, or audio only, I could very easily click-and-drag that file down into the sequence. Well, I want to take this one step further. So here let's say we want to actually make our Video Edits at exactly that point in time, but we want the Audio Edits to be somewhat different. Now the way that we can differentiate the Audio Edits from the Video Edits, is to use the Alt key while we are making those adjustments. So what you will do is hold down the Alt key and click on the bottom-half of the Time Ruler. Now what you are doing here is splitting the audio and video for editing purposes. You can notice that there is a line through the center, the green reflects the audio and that dark gray reflects the video.
So now if you wanted more audio on the head and tail of the file, you could extend it just like that. So now you have your video In point, your video Out point. You have your audio In point and your audio Out point. Now what this is called here would be a J cut, where the audio comes in first and then the picture. And then you have over here what would be an L cut where you have the picture ending and the audio extending. So if I grab this clip and drop it down into the sequence you will notice that at the beginning, the audio starts before the video, and at the end the audio ends after the video. Again both of these values defined pretty easily just using a simple modification key inside the Source Monitor.
