In this movie we are going to learn about Ripple Edits and Roll Edits. They are actually two different types of trimming the edge of a clip to make sure that your show actually is paced perfectly. For instance, let's take a look at these first two shots. We have a shot of the person turning on light switch, and then the light turns on. As you see, that would be pretty boring.
What we want to have happen is we want to see the light get flicked on, and as soon as the switch clicks, I want to cut to the light and see the light turn on, which means I need to trim the tail of this clip and the head of this clip in. If you notice we trimmed clips before, we learned how to do that by making clips longer and shorter, and if I hover my mouse over the edge of the clip, it points to the direction of the clip I want to shorten, and I could just drag this all the way to the point where we see the light get turned on and then just let go and then I have this big gap, and then I am going to go ahead and remove the gap.
I could right-click and Ripple Delete, and then I'll do the same thing here, and right before the light comes on, there we go. I have another gap and right-click and Ripple Delete, and now we have perfect timing. That works just great, but it's not very fast. So let's go ahead and undo several steps back to where we were at the very beginning. There we go! I think I hit undo four times and there we have our lousy timing. So instead of using this traditional red trim tool, I can go over here, and again, we are going to go to tooltips, and you see there is an option for a Ripple Edit tool.
Now if you notice the color has changed, and if I go ahead and I grab the light switch, and I make it shorter, just to where he flicks the switch, I can let go. But do you notice how the program window looks a little different? Before we just saw the last frame of the first clip, what we're seeing now is not only the last frame of the first clip, but on the right side we are seeing what it's going to cut to assuming the gap isn't there. As soon as I let go of my mouse, not only does it shorten the clip, it closes the gap.
So instead of doing it in two steps where I shorten it and then I had to remove the gap, I can do it one. I can do the same thing the other way around. Let me go ahead and deselect this and nothing is selected, and if you notice now when I hover my mouse over it, I can click and now I am going to drag to the right. I see this switch at the very end, but I'm going to go ahead and just move it right before the light turns on, and it deletes everything in front and removes the gap. Let's go ahead and play that.
Well, I was a little bit off there and that definitely happens. So what I want to do I want to go ahead and trim a little bit more at the beginning, and I am going to show you a really cool technique so you don't have to step off and step back on. Let me zoom in so you can see it little clear. I am going to hit the plus key a couple of times, and I want to grab the left side, and I don't want to have to click off there. Well, there's a great little keyboard shortcut, and it revolves around the T key. If you hit Ctrl+T, every time I tap the T key you notice that it's toggling between five different states of trim.
We saw the red ones. That's the trim that's going to leave a gap. There is also one where it's on both sides, that's a Roll Edit, and we are going to look at that shortly, and then if I tag it again I actually get the yellow Ripple Delete trim edit, and I can go ahead and grab and pull this to the left just until the switch is clicked and now we go ahead and hit play, and our timing is pretty good. I could go ahead and hit Ctrl+T and really refine this because I think I need to pull it back just a little bit. And if you notice I can pull to the left with the yellow cursor, and it's going to just add media to beginning and push everything down.
It's not going to remove any of the clip on the left. We'll get that just right and look at playback. Perfect! So that's the advantage of using the Ripple Trim tool in Adobe Premiere Pro. Now I also mentioned something called a Roll. So let's go ahead and jump back to see the entire timeline, and I could hit the minus key several times, but instead of that I am going to press the backslash key and that's going to show me my entire timeline.
And if I go over to these clips on the right, and I hit Play, I have one clip that's the fan and that's four seconds long, and I have another clip of these wind turbines and the moon in the background, and it'll be great if they were equal length. I don't want to go do that whole ripple thing, because then I'd be deleting and moving things around. So I am going to go ahead and I'm going to switch from my Ripple tool to my Rolling Edit tool which is the N key. So I click on that, and now if I come over here and click on the edit points and with it clicked I can move my mouse left or right.
You'll notice once again I see the last frame of the first clip, which is the fan, and I see the first frame of the incoming clip which are the wind turbines, and where ever I let go of my mouse is where the cut is going to move to. So it's very easy for me to roll the edit point to make one clip longer and the other clip shorter. Unlike the Ripple Delete where I am changing the duration of my show, with the Roll Edit what I take from one clip I give to the other.
So the total duration of these two clips will always stay the same. And that's a great tool to use when your timing is perfect, but maybe you cut to something a little bit too early or little bit too late, but you don't want to change the duration of your whole show. A really cool trick is if you know exactly where you want that edit to occur, you can simply select the edit point with the Roll tool, position your playhead exactly where the cut should be, perhaps on the musical beat, and simply press the E key for what's called an Extend Edit.
And as you see, the edit automatically moves to the precise location where your playhead was parked. The Extend Edit is one of my favorite tools, and it's easier to remember, because once you have the edit selected you press E for extend.
