In this session we're going to look at a brand-new tool introduced in version 11. And I've got to say, it's one of the coolest tools in the whole Premiere Elements toolkit. The Time Remapping tool will take a clip from your movie and it will suddenly shift it into a fast motion or slow it to a crawl. Then just as quickly, it will Shift it back to normal speed. Now, it's a very cool effect and one you see a lot in today's Hollywood action movies, and you can do it here on your own computer. Let's take a look at how. On my timeline I've got a clip of somebody riding a bicycle--that's actually me riding the bicycle past the camera-- and we're going to time shift it.
Now to use the Time Shift tool you have to make sure that your clip is actually selected on your timeline or the tool won't work. Go to the Tools button on the Action bar along the bottom of the program, scroll down if you need to, and select Time Remapping. This pops us into the Time Remapping Zone. And one of the cool things about time remapping is that you don't have to slow down or speed up your entire video clip. We can set areas of it and in fact make one area slow motion and another area fast motion on the same clip.
Let's see how it's done. This is the CTI playhead. I want to position it right where I'd like my time zone to begin. So I like right about here, where the bicyclist is coming by. Tight here. Now to add a time zone or an area that we're going to time shift, you can do that one of two ways. Either click on Add Time Zone-- this little button here underneath the timeline--or simply click on the plus sign button here on our CTI. Let's do that. Now we have a defined area. This is called a time zone, and this is the part of the video that we're going to time shift.
You notice right now it says 1x because it just is going at one speed; it's not been changed yet. We can extend or compress it. I am going to extend it so that it goes all the way about there. And notice that when we have a time zone selected, you have a slider that appears underneath it. When there's no time zone selected, no slider. And when the time zone is selected the slider sets the speed of time. Now, pick note of something here along the bottom of the timeline: we have something called duration. Right now that duration is 1.4 seconds.
It's going to change of course when we change the speed that our movie plays. We can set our movie to slow down. Let's say we'll slow it down about 1/3. Notice now that our duration has gone from 1.4 seconds up to 4 seconds, so it's going to slow to 1/3 speed. I also recommend whenever you do time shifting you select the option for Frame Blending. Frame Blending will help kind of smooth out. So, for instance, we're actually adding frames. We've got 29 frames per second, but since we're slowing it down, we've dropped down to about eight frames per second.
Frame Blending will help smooth that out, so it's going to look jump, jump, jumpy with less frames per second, but it's going to be a nice smooth transition. That's really it, but you know what? Before we play it back, let's render it. Rendering will create sort of a temporary video file and show us a much cleaner example of what our output is going to look like. And now we can look at our movie. Let's see what happens when it slows down, about halfway through. Bicyclist arrives, suddenly drops down to 1/3 speed. Pretty cool.
Now, of course jumping into an out of that time zone is pretty abrupt. He's traveling here at one speed; suddenly he is traveling at 1/3 speed. Fortunately, the program has these little Ease In and Ease Out options in the lower-right corner. Click Ease In, click Ease Out, and now instead of just immediately jumping to slow motion or immediately jumping to fast motion, it's going to be kind of a down shift. So let's watch it. Cool right? Now of course you have the option also, you can see on the slider underneath there, of setting it to play in reverse and we can create an additional time zone on the same timeline or on the same clip. Click on plus, stretch that out.
Now this one we'll make go faster. Let's send that about four times the speed. Ease in and ease out of it and we'll course we'll frame blend it. Render it, move the CTI to the beginning of the clip, and then let's play it. And you can play it either by using the playback controls underneath the monitor or simply by pressing the Spacebar on your keyboard. Here we go: fast motion, slow motion. When you're done you just click on the Done button, but I want you to notice something.
I'm going to zoom in a little on the timeline by pressing the plus button a couple of times. Look what happened to our audio. Because we sped up a part of the movie and slowed down a part of the movie, the audio went out of sync. Now the Time Stretch tool that's also in Premiers Elements, you can use and it will both slow down and speed up the video and audio at the same time, but the Time Remapping tool affects only the video. So if you were to watch this, the audio would go out of sync. And in fact if I only have slow motion on here, my video would be much longer than my audio.
So one of the things I recommend--I am going to reopen the tool, click on the Tools button, go back to Time Remapping, and select the option to remove the audio. And of course this is going to give you warning because you're just throwing out your audio clip completely. But this particular effect is one that is best not to try to sync the audio up with it. When we click Done, we go back out to the timeline and the audio is gone completely, but our effect is intact. Speed up and then slow down with Time Remapping.
As I said it's a really cool effect, but what impress me most about it is just how easy Adobe made it to use. You can apply several of these time shifts to a single scene, and it's very effective with frame blending, especially. It means that when you slow down a video, even to 1/8 speed, it still looks terrific and the slow motion looks very, very natural.
