Join Maxim Jago for an in-depth discussion in this video Time remapping, part of Premiere Pro CS6 Effects Workshop.
As well as adjusting the overall speed of your clips in Premiere Pro. You can also have the speed adjust over time. Its actually a very, very easy thing to do but the interface is a little bit different to working with other effects. Let's just have a look at that. I've got my clip here on the timeline. We're just going to zoom in a touch and just give a little bit more of the room to this clip. And maybe upscale this a little bit. I've got the Key Frame menu here on my clip set to timing mapping and speed. And I could use this rubber band to make a flat level adjustment. And that will be fine and I'm adjusting the speed of the time. But there's another way.
I'm just going to undo and expand the time remapping controls here in the Effects Controls panel. I would say that most of the rubber banding that you're going to want to do in Premier Pro. You're pretty much always going to want to do opacity for video, and, amplitude or volume for your audio. And most of the time, that's all you're going to want to do. The exception is, perhaps, speed change. Because. You can see the speed change adjustments, in time, in context on the time line. It's pretty useful. Let's say for example, I'm going to pick a moment here.
Let's have her working at normal speed, and then just about here, let's have a slow section where this guy is walking. I really want the audience to draw their attention to this guy. So what I'm going to do is. Right now we're at 100% speed. I'm going to hold down Ctrl or Cmd, on my keyboard while I click, to add a keyframe to this time remapping rubber-band. Just at that section where he's doing that big stride. An then about here maybe, I'm going to add another keyframe. I'm going to Ctrl click. I can do exactly the same thing, up here in the Effect Controls panel. I can click on the regular, add room with keyframe button. It's going to do the same thing.
But look at this. Notice that these keyframes are a little bit different to the ones that you would normally observe, if I go back to my Opacity and add keyframes, they're just little marks on the rubber band. Let's just undo a couple of steps there. These keyframes, for time remapping, are a little bit different for a reason. They allow you to ramp the adjustment, and I'll show you what I mean. So, I'm going to first of all click on the gap between these two keyframes, which is the section where this guy is walking.
And I'm just going to drag down, let's go down to 60%. And you'll notice. The duration of the clip changes, it leaves the audio behind. You can always fix that audio adjustment by clicking and dragging with the Ray Stretch tool. The only problem, I need to unlink to do that. Let me select, and then, there we go. The only problem with that is of course I've changed the overall speed of the audio. What I really need to do if I just undo that is a little bit more laborious.
I need to get my Selection tools select my video go to my keyframe have my audio selected. Do Ctrl or Cmd K to add a cut, go to the next one, Ctrl or Cmd K to add a cut again and oops let's get that add a bit more accurately, yep so now I've. Created a little adjustment here to the audio. Rather I've, I've just singled it out. And now I can drag this over and get my Restress tool. I can click and drag out the audio.
And I've created that longer section of audio that should match the movement on screen. Let's have a little listen to that. I'm just going to turn on the Audio. (audio playing) We're still hearing much in the way of footsteps anyway but (audio playing) it's there anyway. If you had some clear footsteps you'd get it. It's not very good visual feedback, I have to admit. But the important thing is you can do it. Now, let's turn the audio off again. So right now if we just watch the visuals you can see we've got full speed, and then it slows down, and then full speed again.
Let's make this really obvious. I'm going to go back to my Selection tool and drop this to maybe 40%. So let's not worry about the audio for now just have a look at this. It goes in slow very, very slow. You see a little bit of stuttering there because of the speed of it and then full speed. And then maybe we can do the same thing for the car. Let's Control or Command click. Drop the speed of the car down a little bit. It comes in at full speed and we'll drop down to maybe 30% will make it really slow. Okay. Boom. Now, the problem is we're getting this abrupt speed change adjustment.
We're going from full speed to a little bit slower. It's too quick. So that's why we have these special key frame markers. If I click on one edge of one of these keyframes, and I can do the same thing up in the Effect Controls panel, I've got the same kind of control there, I can click and drag out, let me get this, there we go, and what I'm doing is applying a graduated adjustment to the playback speed. You can see, if you look up in the time remapping control scheme in the Effect Controls panel.
It's going for 100% and then gradually moving down to the 40%, and let's play that. It's a little bit late, isn't it? So maybe what we can do is just move that later in the shot. I'm just clicking and dragging the middle of the keyframe here. Let's have another look. (NOISE) Much better. And then maybe we can spread out this, as well. And have that run-pop list, do the same thing for the car.
Much more natural looking. Notice as well as soon as I select one of these keyframes, and if I can show you up here as well, notice that I've got bézier handles if I zoom in fact let me resize this a little bit. And zoom in a little bit as well. I can use these handles to adjust how curved that adjustment is, so I'm effectively giving this a more natural curve.
And I'm adjusting that transition, so if we play this again it might be a bit too subtle to see, but it's just giving a natural fall off for it. Now as I mentioned, the problem of course with making your slow mo slow is that Premier Pro doesn't really generate interframe content. Does a really nice job of frame blending, with the right footage, it can look great. But it doesn't do interframe content generation. And although I know this is of course about Premier Pro, just to show you the difference in After Effects, if you do have the suite.
If I right-click on here and choose Replace With After Effects Composition. This is going to throw me into Aftereffects, and generate a composition automatically based on the clip so it's the right composition size and so on. And notice that this time remapping data has come with a clip into Aftereffects automatically. So it's a perfectly good workflow to set up your time remapping in Premier Pro. And just make a little note for yourself later maybe even if I toggle back sometimes I'll just put a marker in. Double-click and say something like switch to ae for rendering, and OK that, and then I've got a little reference here if I hover over it, and I'll just populate the timeline with these markers of things I need to do. So now over in After Effects, all I need to do is render my conversation and play it back.
I've got the time remapping already on here so if I render this I'm just going to press the zero key on my numerical keypad. So it's going pretty fast as its rendering. And let's just have a look at that. There she goes. There's our guy, pretty smooth not too perfect but pretty good. Now what you'll notice is that sometimes when you send media across to After Effects in this way it becomes a nested. Composition in its own right, and I actually want to get to this time remapping on the original clip.
So I'm going to select the Time Remap entry here on the timeline, and I'm going to press Control or Command + C to copy it. Then I'm going to double-click on this composition which is nested in After Effects Select the layer. Ctrl+V, Cmd+V to paste. This is going to enable my frame blending option in AfterEffects with which I can get a much smoother adjustment to speed. So I'm going to turn it on. High quality, two clicks. I'm going to turn on the overall Frame Blending Rendering option. And now I'm going to run preview this and see how the result compares. And you can see actually this is going to give me some weirdness because where I've pasted my keyframes I had my play head set too late in the clip so I'm actually getting some stillness and then oh everything happens and then the clip runs out.
So I need to undo and remove those key frames, reposition my play head at the start of the clip, Ctrl, Cmd+V, to put the keyframes back on. And ran preview again. >> Action! >> And here we go. And just look at this ramp. I'll just turn off the audio here, so just look at that.
Beautiful, beautiful adjustment to the playback speed, totally smooth, it's fantastic. There's the car, slowing down as well, it's wonderful. So now, I can go back to that parent comp, I can just get rid of the timely mapping data, because it's on a linked composition anyway. I'm going to get the sub composition, inside of it. Back inside Premiere Pro, I've got the results of that although it will need to render ultimately I'm going to get beautiful slow motion so you can actually benefit from making your speed change adjustments inside of Premier Pro and send that work into AfterEffects if you are using it.
I won't undo this I'll leave it as it is in the Assets so you can have a look at these and compare and contrast for yourself.
