We're going to jump back out of editing for a few movies to talk about some important navigation and customization techniques. In this movie, we'll explore one of the most important navigation tools in Media Composer, JKL Navigation. Moving quickly and deliberately, or slowly and precisely, through the Timeline is essential in the editing process. So far we've covered several ways to do this. You can press play by pressing your spacebar or 5 key, you can scrub with your position indicator, and you can step through either one or ten frames at a time using your 1, 2, 3, and 4 key.
Probably the most important and most often-used technique for the Timeline navigation however is JKL. JKL is a variable-motion and direction-control device. Let's first talk about J. When you press it once, it goes backwards in real time. Then as you press it more and more times, it gets faster and faster in reverse. L does the same thing, but forward. You press it once, it goes forward in real time, and then you press it more and more times and it gets faster and faster.
Let's take a look at how this works. I'm going to go ahead and press L once to go forward in real time. I'll press it again to go double speed. Again, and I'm at triple speed. I'll press it four times, and it actually sends me to five-times speed. And I'm going to try to press it five times, and we're eight-times speed right now. So this lets you really zip through the sequence. I can do the same thing with J, in reverse. Once, in real time backwards.
This is double-time backwards. Triple. And then I press it four times that sends me to five-times speed backwards. And five times will send me to eight-times speed backwards. When I'm doing JKL, K will pause. So I'll just go forward with L, press K, and I pause. But the really great thing about K is that you can use it to go in slow motion. Specifically, if I hold down K and J at the same time, I'll go backwards at one quarter speed.
If I hold down K and L at the same time, I'll go forward at one quarter speed. Let's take a look at this. Let's go ahead and zoom in, because usually when we're going in slow motion, we want to get pretty precise here and I'm going to hold down K and go forward with L. All right. And I'm just going to keep holding K and go backward with J. So, this can help you hone in on exactly where clips start and end.
Lastly, I'd like to point out the location of each of these keys. J, K, and L are right next to one another, right below I and O. This lets you navigate through your clips using JKL, both forward and backward, and at variable speeds, and then you can extend your two fingers up to I and O to mark your in and out points. In this way, you have a lot of power with just three fingers as you navigate through and mark your clips for editing. JKL navigation is an essential part of any editor's experience, and it's important that you work it in to your muscle memory by using it to proceed forward and backward, and at variable speeds, through your sequences as you edit.
