Hello there. In this tutorial we will take a look at the time stretch tool and how to
use it to change the speed of a video clip in Adobe Premiere Elements. I'm currently
working in version 10 of the software, but what I will show you can also be done in version
9 and some other earlier versions of the software. To begin, I've imported a video clip, drug
it down to the timeline so I have it ready to edit. I am in timeline view. I'm planning
to start by dividing this clip into three parts. This way I can do something different
to each segment. I'll drag the current time indicator over to the first place where I
would like to split the clip, about here. Click the little scissors tool, which is the
split clip tool, and that cuts the clip. Now I'll drag the current time indicator over
little further, maybe about here where this car is passing. Then clip it again. I'll split
the clip again. Now I have three independent segments that I can treat independently with
the time stretch tool. So, I'll come over to the first one and I'll click on it. Move
the current time indicator over here. I'll start by speeding up this clip. I'm going
to make it move a lot faster so that traffic will really zoom along. So to do this I go
right above the timeline to the time stretch tool. It looks like a little clock. Click
on that. Then when I come down and hover the mouse over the clip we see that we have a
different cursor. This means that the time stretch tool is active. When I go to the end
of this clip and see the cursor change to the little red bracket then I can drag the
clip to the left and I'm effectively changing the speed of this clip. So now when I play
the clip we see that the traffic is moving very, very fast. We've sped it up. I can make
it go even faster if I like by moving it a little more. So we have very, very fast motion.
So it's quite easy to do. Now for the second clip I'm going to first go back to the selection
tool, right-click delete and close, and select the next clip. This one I will slow down.
So it will do slow motion. I could use the time stretch tool again, but this time I'm
going to use the numerical version of the time stretch tool. So if I right-click on
this, with the selection tool button clicked, I can go up to the time stretch tool right
in the middle of the menu. Another way to get to this is to go up to the clip menu and
go down to time stretch. And this brings up the time stretch tool numerical version. It's
kind of hard to see. Right now the speed is at 100 percent so if I want to change that
I can change the percentage or the duration here. If I change this to 50, 50 percent,
we see that the duration changed. Let me go back and do that again. That was pretty fast.
100 so it's duration was 108. When I change that to 50 it's longer. So it should go slower.
So let's also click maintain audio pitch and that will keep the sound from going really
slow. It maintains the same audio pitch. So if you change the speed it will either make
it sound like chipmunks or like you're dragging and so this maintain audio pitch keeps the
sound normal, sounding normal. So I'll click that. Notice that it really stretched out.
Now I'll click play. It takes a moment to render. Then it's going really slow and if
there was voice narration it would still sound normal because I maintained the audio pitch.
Let's move that in a little. Now over to the third clip. Move the current time indicator
over, selected it. I have the selection tool. I'll right-click, time stretch. This time
I will reverse the speed and I'll keep it the same speed. I'll just reverse it. We're
going to go backwards now. I'll okay that. When we do this, now we're driving backwards
down the freeway. So we've reversed it. And of course the audio track is going backwards
so you get that nice weird reversed speech effect in the process. So that's something
to experiment with. You can easily change the speed. Make it faster. Make it slower.
Reverse it and maintain the audio pitch if you wish. You can also remove the audio track
entirely if you want just by right clicking, unlink audio and video, select just the audio
track and delete it. If you don't want the audio track at all you just want the visual.
So that's it for the time stretch tool, nice and easy to use in Adobe Premiere Elements.
I hope you found this helpful. Thanks for watching.
