Join Maxim Jago for an in-depth discussion in this video Create a group clip, part of Media Composer 8.7 Essential Training: 110.
- [Instructor] It's common to capture separate video and audio on location, and to need to join those separate sources together in post production. Even if your camera has the ability to record sound, it's common just to put any microphone on so you have some kind of reference, but to keep your audio acquisitions separate, if only because it means you've got one less trailing wire for people to step on. Media Composer provides a couple of different approaches to syncing clips, and I'll look at the first in this lesson, grouping clips, and the second, syncing clips, next.
The group clips function is the one used to work with multiple camera material in media composer, but you can also use it to combine your separate video and audio content. So here, for example, I've got a clip, this is shot four, pickup number three, and this does have audio, but I have better quality audio right here that I want to combine with it. I'm going to hold the control key on Windows, or the command key on Mac OS, to select these two items in the bin, and now I'm going to right click on either one, and I'm going to choose group clips.
Before I get into that dialogue, I should mention the multi group option. That's specifically for large studio productions where multiple cameras are given an external sync timecode source. This means that all of the media on the cameras will have exactly matching timecode, and you can collect a number of clips together in one step, and synchronize them using the multi group option. In this instance, we're going to use a more advanced form of automation.
I'm going to go to group clips, and I only have two clips chosen here of course, the video and audio, and I've got a few options for syncing. I don't have dedicated film or sound timecodes, so that option is grayed out. I could have added in points and out points, but I haven't. And I could have chosen source timecode, but I don't think the source timecode on these clips matches, in fact, we can see in the bin that they're really, markedly different. It's possible to have multiple timecode streams on a single clip, and it might be that you are using a dedicated external timecode generator in exactly the way I was describing for the multi group function, and you could use that timecode in this menu if you wanted to.
But what I'm really interested in is this option, wave form analysis. With his option chosen, Media Composer is going to check the audio in both clips, and use it to synchronize them. So, I'll click OK, and a new group clip is added to the bin, which has the name of the video clip. I'm going to double click to open this up, and I'll just jump to the middle, and in my timeline window, you can see that I've got the timeline set to show me the contents of the source monitor, the player monitor, I can toggle back and forth between showing the contents of my current sequence, and showing the contents of the player.
With this view, I'm going to turn on my wave forms, in fact, I'm going to use a useful keyboard shortcut, you can hold down the alt key to toggle all of these off or on. And now, we can see our separate audio. Now, there is a slight mismatch in the sample rate of the separate sync audio, and that's why we're getting this in a paler wave form than the audio one track, which has a matching sample range. I'm going to mute our audio one, which is our original, unwanted audio, and let's have a listen to the new version.
- Listen, Mary, I know coming to the dentist can be frightening. - [Instructor] So, it's absolutely perfect. Probably the quickest way to check is to jump back to the clapper board, which I think is right about here. Perfect, so, with group clips function, I can go through each of my paired video and audio clips and not take the time to add an in or an out marker before getting Media Composer to combine them into new content that I can use in my sequences.
