Digital video is a medium that is now available to almost everyone. It can be captured on anything from a mobile phone to a high-definition camera, and published anywhere from YouTube to Blu-ray discs. In Premiere Elements 4 Essential Training, Adobe Certified Instructor Chad Perkins explores all the video editing capabilities of Premiere Elements 4. Chad starts with a real-world sample project, then covers techniques for importing and editing video; and adding effects, transitions, and animation. He concludes with a final project incorporating all the steps, including exporting and posting. Exercise files accompany the course.
When editing video, it's very common to want to change the speed at which clips playback. If you have video footage for example of someone winning a marathon, you might have want to slow that motion down and have it be this big triumphant slow motion cross through the finish line or what have you. And of course, speeding up clips makes them just look more hilarious hence fun to play with as well. Also it's great for time lapse photography and that type of thing. Where you have very long video clip and you just want to play that back very quickly.
Let's talk about how to do that. Now it's very important that you realize that this task take place in the Timeline, not in the Sceneline. For this movie, if you'd like to follow along, we're going be using the Slow Motion project inside the Chapter 4 folder of your exercise files. The way that we do this is by going to the Clip menu at the top of the screen and by selecting Time Stretch and as you could see when I'm in Sceneline, it's grayed up. So let's go hop on over to the Timeline and now if we go over to the Clip menu and select Time Stretch, you see that it is selectable. So go and select Time Stretch and here we can change the speed of the clip, we can also change the duration.
Remember that speed is linked to duration. So as we make the clip longer, we're basically going to slow it down and if we make the clip that's may be 28 seconds happen in two seconds, it's going to have to go very fast. So there is a link here. There is also an option once we change the speed and if there is an audio track, we can change the Maintain Audio Pitch. Typically, when you slow down the clip, it's going to slow down the audio. So unless you want your audio pitch to be slowed down as well, then check Maintain Audio Pitch.
By the way the opposite is also true. If you speed up your clip and you do not select Maintain Audio Pitch, it's going to raise the pitch, in other words, it's going to make it sound like chipmunks, if you don't check the Maintain Audio Pitch, which is basically going to try and make it so that it sounds the same, just playback a little bit slower or faster. This Reverse Speed, we will talk about in the next movie. For that I'm going to go ahead and cancel this and we haven't changed our speed yet. There is another way to do this and that's actually with a tool here in Timeline and that is this tool here, the Time Stretch tool.
So I'm going to select that and this a little bit easier, at least for me. This is my preference to use because with the feature I'm not really sure how much I want to speed up or slow down. I don't want to keep going back to that dialog box every time I want to make a change. That dialog box is great, if you know exactly what you want to do. So if you wanted to click to playback at 50% of speed, in other words half speed exactly, then that's probably the best way to go, because you can just type in 50%. But this tool will allow you to go in and just manually change it, so you want to speed it up just a little bit, you can drag this into the right. It's not actually trimming it, even though that what it looks like.
What it's doing is it's increasing the speed. As you can see here, it's going to be playing back at a 110% of its speed. Well let's go a little bit crazier, so we could see what's going on here. Speed this up quite a bit and now it's going to be playing at a 188% of the speed, so if we hit the Spacebar and preview this. See those wild dogs are going pretty quickly here. Now, not quite fast enough. So let's go ahead and speed it up a little more and actually, as we talked about in the last movie, let's go ahead and preview this so we have a smoother playback.
So I'm going to go ahead and hit Enter on the keyboard to do a video preview. OK, and after a quick preview, our video is ready go here and it plays back and we have some awesome Benny Hill-esque African wild dogs, which is always a good time. So I'm going to go ahead and hit the Spacebar again to stop playback. I am going to go ahead and hit the Home key to jump me back to the first frame and I'm going to grab the end and stretch this out. This time I'm going to go actually past the original point to make this clip really stretched out and long.
Now its going be playing back at 57%, so almost half speed. So now as we play this back, we will see that it goes very slowly. It's really cool! It's a really great effect and it comes in handy all the time. In the next movie, we're going to look at this same clip and we're going to show you how to play it backwards.
