Video: Trimming with JKL

You already know how to trim and you know how to use JKL navigation, so in this movie we're going to put it all together to introduce one of the most powerful types of trim in Media Composer, JKL trim. JKL trim allows you to perform a trim while playing the video at either real time or at a variable speed. I have my interview sequence here and I have a couple of locators that I've put in saying I need to fix a few things. So let's go ahead and enter Trim mode. If I want to enter Trim mode on these tracks right here, I'm going to hold down Alt or Option on a Mac and I can apply my rollers inside the tracks.

Trimming with JKL

You already know how to trim and you know how to use JKL navigation, so in this movie we're going to put it all together to introduce one of the most powerful types of trim in Media Composer, JKL trim. JKL trim allows you to perform a trim while playing the video at either real time or at a variable speed. I have my interview sequence here and I have a couple of locators that I've put in saying I need to fix a few things. So let's go ahead and enter Trim mode. If I want to enter Trim mode on these tracks right here, I'm going to hold down Alt or Option on a Mac and I can apply my rollers inside the tracks.

Let's go ahead and play a loop and see what we're looking at here. I'll press spacebar. (clip playing) (Female speaker:--ing dancing brings you together.) She doesn't quite say swing dancing. It's cut off a little bit there. So because I have filler on the other side, this can be a Dual Roller Trim. And I'm just going to stay in Trim mode, place my fingers on J, K, and L, and then I'm going to roll back with the J button.

This is going to trim to the left in real time. When I'm done trimming, I'm going to press K. Okay, looks like we've got the beginning of that word added. We added sixteen frames to the B side, and let's go ahead and play it and see if it worked. (music playing) (Female speaker: Swing dancing brings you together.) All right! Great! Let's go into my next locator here. I'm going to enter at rim mode on all four tracks because we don't want our video to Broll to go out of sync.

Let's go ahead and play a loop to see what the problem is here. (Female speaker:--store. In the '30s, '40s, and '50s, as a little girl, she started giving me those clothes.) (Female speaker:--store. In the '30s, '40s, and '50s, as a little girl, she started giving me those clothes.) So it looks like a couple of words are cut off here, but it's not exactly apparent which way we need to go. So let's just zoom in. Let's also enable our Audio Timeline. As you remember, we made this in a prior movie. We could just switch to 3-Audio, or again, I like to use the keyboard, so that was Shift+3.

I'm going to zoom in a little bit more and let's play through. I want to change my watch point from the video to the audio. I'm just going to click on my audio rollers and this way it will loop on either side. I'm going to go ahead and press spacebar, and then I'm going to press Q to play just the A side. (Female speaker: In the '30s, '40s, and '50s. In the '30s, '40s, and '50s.) All right! That seemed fine. Let's go ahead and do the same thing, but for the B side.

I'm going to press spacebar, and then I'm going to press W to play just the B side. (Female speaker: --little girl, she started giving me those clothes. --little girl, she started giving me those clothes.) So it looks to be a problem with the B side. So we need to enable the B side, and I'm going to roll back with J again, but this time I'm going to go very slowly, so I'm going to hold down K at the same time that I press J. This will enable me to go in slow motion or one quarter speed.

So I'm going to hold down K and roll back with J until I think that I've got that dialogue back. (clip playing) All right! I heard a little pause there. I'm going to go ahead and let go, and let's play through. (Female speaker: In the '30s, '40s, and '50s, and since I was a little girl she started-- Well, we got it back, but I think we got a little bit too much. We don't need her saying "Um" at the beginning. So I'm going to go ahead and play through and see if I can get a better idea of where this can start.

(Female speaker: In the '30s, '40s, and '50s, and since I was a little girl she started-- I think this right here is the word since. So again, I'm going to hold down K and then go forward with L. (clip playing) I actually hear it right there. I'm going to let go right here, and let's go ahead and play through. Press spacebar. (Female speaker: In the '30s, '40s, and '50s, and since I was a little girl, she started giving me those--) We got it. So by going back and forth in slow motion, using JKL, we were actually able to play the edit as we were trimming.

This is the power of JKL. We can play through as we're trimming and this is why it's called dynamic trimming. You actually see the footage, watch the result as you see trim in either real time or at a variable speed.
