There are two main methods of trimming in Media Composer: either trimming using the timeline tools like we did in the early part of this chapter or trimming using Trim mode. Here we are going to be doing that. We are going to be using Trim mode. And I switched off my timeline tools. By the way, on the outside border of the Smart palette here is a toggle that actually allows you to toggle your timeline tools on and off, your Smart tools on and off. [00:0 0:27.37] So if I did have my Smart Trim tools on and I toggled, I'll be able to toggle them on and off both together, like so.
But I am actually going to leave them all off for now, because we are going to be using Trim mode. At the moment, I am in Source/ Record mode. How do I know that? Well, two things tell me that. First of all, I have the Composer window with the Source viewer and the Record viewer, but also here I can see that I am actually selected on Sources/Record mode, both at the bottom of the Composer window and here in the Timeline palette. So if I wanted to switch now into Trim mode, I can activate Trim mode using this button here or indeed this button here or the U key on my keyboard.
First though, I need to delineate which tracks I would like to trim with. I am going to concentrate on V1, A1, and A2 at this transition point, and because I am going to be concentrating on these tracks, I want to be monitoring those tracks as well, so I can see and hear what's going on at that transition point. So now, using U on my keyboard, I am going to enter myself into Trim mode. Notice a few things change. First of all, when we enter Trim mode, by default we enter with a dual-roller trim on our material.
In addition the viewers have now changed to represent the outgoing material and the incoming material. We have got our pink counter boxes here, and we could start trimming away in a very similar way to how we did so using the Smart tools in the previous part of the chapter. If you went through that, you may now start to think, well, hang on a minute, didn't we just use these tools in the previous segment? And the answer would be yes. Because even when you activate Trim using the Smart tools here, you will, by default, enter Trim mode as you are trimming. When you click back on the Time code track here you will exit Trim mode, like so.
So in actual fact we have already being in and out of Trim mode several times, but we've been concentrating on using the timeline, so I am dragging transitions backwards and forwards. Now what we are going to start to do is use some of the additional tools in Trim mode to move our transition points around. Now the first thing is, how do we change from a dual-roller trim to a single-roller trim? Well, there are couple of ways of doing that. Here in the interface we've met Trim A Side, Trim B Side, Trim Both Side.
So click on Trim A Side, I mean a single roller trim. The same for B Side. If I trim A and B sides, I am back to a dual roller trim. If I click on the left-hand image, I can activate a trim on the outgoing material; if I click on the right-hand image, I can activate a trim on the incoming material; and if I click right in the middle, I can activate a trim on both sides. Notice also that when I swipe backwards and forwards here, regardless of whether I'm in a single- or dual-roller trim, this green bar activates.
That's really telling me which side of the edit I am going to be listening to, if I choose to do a JKL trim, a dynamic trim. So, for example, with this side highlighted, if I roll forward slightly, I'm listening to this side. If I swipe over on to the right- hand side, I'm listening to the incoming material instead. Now because in Trim mode the Composer window is no longer showing the Source side and Record side, you can consider all of these tools underneath both of viewers applicable to both sides.
It isn't that these tools are affiliated with the left viewer and these tools are affiliated with the right. They are all controlling both viewers at the same time. So let's go through some of these tools and what they do. Here, for example, we have the Rewind and Fast Forward buttons. What these doing in Trim mode is take us between the various different transition points in our sequence, like so. And then we have a Loop Play, which allows us to loop play over our transition point. (Female speaker: In front of the phone company in Los Angeles. Since I was a little girl, she started--) And then over on this side we have these arrows which allow us to move the transition that we have currently selected by 10 frames or a single frame forwards or backwards down the timeline.
Next to that, we have these two values here, 2 seconds and 2 seconds. And that correlates with our loop play. It's going to preroll 2 seconds and then play postroll 2 seconds. These can be changed here if necessary. So if I use my Fast Forward button to move to the next transition point and listen back to it, we can see what we need to do here. (Female speaker: Just in elementary school.) So it's just a bit of a gap on the end there that may be needs to be trimmed off. So if we wanted to do a dual-roller trim, all I need to do is click on my arrows here and trim back a few frames until I've remove the excess material on the end of my edit, like so.
Let's do another loop playback using the spacebar to see how that sounds. (Female speaker: I was just in elementary school.) Okay, that's a lot better. So let's move to the next edit and play that one back. (Female speaker: Well, there's this--) Okay, so she sort of fumbles at the beginning of the line there, and probably where we want to come in is on the word, 'there is this weird line.' (Female speaker: Well, there's this weird line.) So what I'd like to show you this time is how we can use the same commands but on the fly as we are looping back to trim down the incoming or outgoing sides of our edits.
The keyboard shortcuts for these keys are M to trim left by 10 frames, the Comma key to trim left by 1 frame, the Period key to trim forwards by 1 frame, and the Forward Slash key to trim forward by 10 frames. So using those keys, let me show you how that works. I am going to drop into the Loop Playback mode and since I really need to remove material from the incoming side, I am actually going to click on the incoming side and make it a single-sided trim.
So drop into Loop Playback mode, and I'll use my keyboard shortcuts to trim up the head. (Female speaker: Well, there's this weird line.) (Female speaker: Well, there's this weird line that you have--) (Female speaker: Well, there's this weird line that you have to try--) (Female speaker: Well, there's this weird line that you have to try to--) (Female speaker: Well, there's this weird line that you have to try--) That's pretty good. So we are able to actually update our edit in iterations over time, and each time it loops back, a new keyboard entry will initiate a new trim.
So we can keep on seeing the results of our work play back until we are happy. The nice thing about this is I can stay in Trim mode without having to go back in and out and play back to see what the results of the trim were. So we've seen some examples of both single- and dual-roller trims using the interface buttons, as well as dynamic trim techniques. And we've also seen that the Trim mode interface itself has a number of specialized tools that give us great feedback in real time about exactly what we're doing.
In the next video, we'll look at using these tools in conjunction with transition effects.
