Guys within this lecture you are going to look at how to change the content of a video player within
the timeline without changing the time that this video is in the timeline.
For example this accent or this.
OK.
And then I want this video to start at 10 seconds just 10 seconds over here.
To be precise I'm going to trim it.
Here you are.
And then I wanted to end a 20 second.
I would limit that again but whatever is happening in the video when it is appearing is not what I want.
What I'm going to show you the technique how to change the content.
It's called sleep in fact but in after the fact is called panning this method will only work if you
have left and right handed.
So the left handle is some frames on the left.
OK.
Of the video itself that you haven't put in the time line you have trimmed from 10 seconds to the beginning
and you need also the hands on the right.
It means you have trimmed from a certain point to the end of the video.
So you have some space from left and right to move the content of the view.
The first option goes like this.
Not as the mouse pointer when I come to the Left Handed it turns into a double row with two bars.
It means I can click and move the video.
OK so I'm changing the content of the video.
Usually what you do you come to the point all the output and you click to change the content and decide
where you want your video to start.
For example from here.
OK or not both of course you come to the point and you decide OK where do you want the video to end.
OK guys.
So I wanted to start at a point and someone else that's not included then you need to split.
We see that later.
So actually this is the math that if you can see the handle is that right.
If you don't have them you can do that.
But there is also a tool in aftereffect.
This is the pen behind or anchor point to it.
So actually it works for the anchor point too.
And also it's a band behind it.
So instead of just coming to the handles when you are in the pen behind tool you can click and drag
your player.
So you decide for example come to the important.
This is what you usually do and decide exactly where you want it from time to time you want to come
to a certain time.
You only save 15 seconds or so and you decide where your video should be.
15 seconds for example on the transition over here.
So this is the pen behind tool but it's got the composition here.
I have put some keyframes.
Now usually what happens you will draw a shape and you will change the position of the anchor point
and you still in the pan behind tool and you come and click and you say nothing is moving.
Well actually this is a shape player.
It's very long.
It's for the whole content of the composition.
So if you have the pen behind you can't pen anything.
Just one ship.
But if you select a keyframe and use the pen behind to move to the right for example notice it's moving
the keyframe while extending the sheer pleasure.
So the shape that is not cut you have a lot of left or right handers here.
You know what's happening.
If Sellick the first keyframe the same will happen if Selek both of them now actually just moving the
lower left and right with the selection to go.
Now when it comes to videos like this player and I didn't select any keyframe of course I'm panning
left and right.
OK within the content of the video.
Now if I select it keyframe you are not is the keyframe is moving.
And you know some funny things are happening if you don't notice which tool you are using undo under
something as I want to show that I forgot here.
I want to change the color.
First of all here I'm going to take it to blue something that we can see them now.
You'll notice when I pan left and right if I go too much on the right where it is not really the start
of the shape player we started the shape there when we created it.
At this point over here.
So you have these small dots over here are the small oblique lines.
It means this layer has been shifted to the right.
But then at the end here they don't appear OK.
So you will have this kind of oblique nine to tell you that OK you shifted this earlier guys.
So this is how to use the pen behind tool and remember when you selecting keyframe is going to move
the keyframe very practical method when you want to delay and any machine for any kind of shape or video.
By the way everything I talk about here for the shape players or the steel players then it works for
the images OK and even for some of the video techniques will work for images.
But of course you're not going to pan an image.
It doesn't make sense.
It's fixed.
So this is how to use the pen behind tool.
And this is how to change the content of your video when it's in the timeline keeping the time of the
video constant.
I'll see you in the next lecture.
