Join Maxim Jago for an in-depth discussion in this video Review of Trim mode, part of Media Composer 8.7 Essential Training: 110.
- [Instructor] Once you've found the shots that you want and put them into a basic sequence, you're going to want to finesse the timings of the cuts, and of course that's where Trim Mode comes in. I want to just look at some of the more advanced Trim Mode features, and quickly skim the options that we have there. I've got both of my Trim Mode smart tools selected here, so I'm going to click on a cut, and that's going to take me straight into Trim Mode. You'll notice that, as is so often the case in Media Composer, you'll need to choose both time and a space, and here I've got the time selected, I've got the right cut, but I haven't got audio 1 turned on.
So I'm going to turn on my audio track, and now I've got trim rollers on both the video and audio parts of these clips. Notice that the clip to the left of this cut has no audio. Which is fine, that's exactly how I want it to be. This is a good moment to thank EditStock for supplying us this content, which is just perfect for testing out things like the trim tools. Now I've got a dual roller trim here, and, as you'll have seen in our beginners lessons, if I click to the left of the line in the Composer window, I get a left trim, if I click to the right, I get a right trim roller.
This is trimming the head of the next clip. And I can click in the middle to get a dual roller trim as well. If you're ever in any doubt about what's going to happen when you trim in Media Composer, you just need to look at where the rollers are. Wherever there is a trim roller, no matter how complex or advanced the trim is, anything you do will apply to that roller, and all of the rollers that are on screen. As you'll know by now, we can click up here to trim left eight frames, or one frame, and of course, it's not really eight frames, it's 1/3rd of a second, and we're working on a 24 frames per second project here.
And down here we can specify how long a loop playback's going to be. Right now, my system's set to play one second moving up to the cut, and two seconds after the cut, and I don't have any transition applied right now. Personally, as an editor, I've never used the trim tool option to add a quick transition. For me, trimming is about setting the timing of a cut, and transitions are a different stage in post-production. But, if you're working on fast turnaround content like news, you might find this very very helpful.
This is the same Quick Transition options that you'll see when you click the Quick Transition button at the top of the timeline window. This is a dual roller trim, as I mentioned, and so if I click eight frames to the right, I'm moving the rollers eight frames later, adding eight frames to the clip on the left and removing eight frames from the clip on the right. This type of trim won't change the duration on your tracks. You can use a numerical keypad to apply adjustments, as well.
So for example, now I'm pressing +2 on my keypad, and if I press Enter, I'm now at 10 frames. And if I, for example, type in +112, Media Composer puts in the colon for me, and I'm now, not adding 112 frames, but instead I'm adding one second and 12 frames. There's even a rarely known feature when using shortcuts of that kind that you can force Media Composer to count frames instead of adding the grammar.
So for example, if I type in -1:00, Media Composer will read that as minus one second. Let me just press the Enter key, and you can see how trim rollers move. I'm just going to undo that with Ctrl + Z or Cmd + Z. But, if I type in -1:00, followed by f, for frame, just watch what happens to this number count. Media Composer has read the number as a number of frames, 100 frames, and then translated that into seconds and frames.
100 frames in a 24 frames per second project is four seconds and four frames. So I press Enter, and we get a much bigger change, so I'll just undo that as well. If I press the Spacebar now while I'm in trim mode, Media Composer is going to loop play over the cut. And while I'm doing that, if I want to, I can use the Go To In or Go To Out keyboard shortcuts, which by default are Q and W. Not to jump the playhead anywhere, but instead to choose which side of the cut I'm going to view.
Let's take a look at this. I'm going to mute the music here, because I want to hear the dialogue, and I'm going to press the Spacebar. - (footsteps) Hi. (video loops) - [Instructor] And now, I've pressed the Q key, you can see over here, where my pre-roll and post-roll settings are, I'm just getting the pre-roll. Let's try W. - (footsteps) Hi. (video loops) - [Instructor] And Q again.
And if you press the key again, Media Composer will return to loop playing across the entire cut. - (footsteps) Hi. - [Instructor] Now this is a pretty deep use of the trim tools, but as you grow in familiarity, well, in any case, you're going to spend a long time trimming in Media Composer, it's one of the key operations of non-linear editing. And so, this nuanced understanding of the tools can only help to speed up your use of them. There's one more thing I'd like to mention.
I'm going to turn on the Caps Lock key on my keyboard, so that as I scrub, I can hear the audio from the system, and I want to draw your attention to this little green line under the monitors in the Composer window. That green line indicates which side of the cut you're going to hear as you trim. So, right now, I've got the left side monitored, and if I click and drag the rollers, no sound at all. If I were to change the side of the edit that I hear while I trim this way, all I have to do is move my mouse over the right hand monitor in this trim mode.
Move it to the left, I'm trimming the left, move it to the right, I'm trimming the right. Again, look out for this green indicator. Now, as I drag, (distorted audio) I'm getting the right side of the cut to listen to. So those are just some useful, deeper-dive, features in the Trim Mode in Media Composer.
