00:00:01,850 --> 00:00:08,240
Guys within this lecture you are going to look at how to change the content of a video player within

2
00:00:08,240 --> 00:00:14,160
the timeline without changing the time that this video is in the timeline.

3
00:00:14,180 --> 00:00:16,910
For example this accent or this.

4
00:00:16,960 --> 00:00:17,490
OK.

5
00:00:17,750 --> 00:00:21,990
And then I want this video to start at 10 seconds just 10 seconds over here.

6
00:00:22,580 --> 00:00:24,890
To be precise I'm going to trim it.

7
00:00:24,890 --> 00:00:25,670
Here you are.

8
00:00:26,510 --> 00:00:29,680
And then I wanted to end a 20 second.

9
00:00:29,910 --> 00:00:37,390
I would limit that again but whatever is happening in the video when it is appearing is not what I want.

10
00:00:38,280 --> 00:00:41,570
What I'm going to show you the technique how to change the content.

11
00:00:41,580 --> 00:00:50,770
It's called sleep in fact but in after the fact is called panning this method will only work if you

12
00:00:50,770 --> 00:00:53,530
have left and right handed.

13
00:00:53,830 --> 00:00:58,290
So the left handle is some frames on the left.

14
00:00:58,290 --> 00:00:58,810
OK.

15
00:00:58,870 --> 00:01:04,930
Of the video itself that you haven't put in the time line you have trimmed from 10 seconds to the beginning

16
00:01:05,410 --> 00:01:08,220
and you need also the hands on the right.

17
00:01:08,260 --> 00:01:12,500
It means you have trimmed from a certain point to the end of the video.

18
00:01:12,850 --> 00:01:17,470
So you have some space from left and right to move the content of the view.

19
00:01:17,770 --> 00:01:19,410
The first option goes like this.

20
00:01:19,600 --> 00:01:25,040
Not as the mouse pointer when I come to the Left Handed it turns into a double row with two bars.

21
00:01:25,060 --> 00:01:28,650
It means I can click and move the video.

22
00:01:28,780 --> 00:01:32,500
OK so I'm changing the content of the video.

23
00:01:32,500 --> 00:01:38,620
Usually what you do you come to the point all the output and you click to change the content and decide

24
00:01:38,620 --> 00:01:40,500
where you want your video to start.

25
00:01:40,510 --> 00:01:41,860
For example from here.

26
00:01:42,160 --> 00:01:50,110
OK or not both of course you come to the point and you decide OK where do you want the video to end.

27
00:01:50,410 --> 00:01:51,090
OK guys.

28
00:01:51,190 --> 00:01:55,620
So I wanted to start at a point and someone else that's not included then you need to split.

29
00:01:55,630 --> 00:01:57,200
We see that later.

30
00:01:57,250 --> 00:02:01,330
So actually this is the math that if you can see the handle is that right.

31
00:02:01,390 --> 00:02:02,970
If you don't have them you can do that.

32
00:02:03,300 --> 00:02:06,030
But there is also a tool in aftereffect.

33
00:02:06,040 --> 00:02:08,960
This is the pen behind or anchor point to it.

34
00:02:09,160 --> 00:02:11,190
So actually it works for the anchor point too.

35
00:02:11,230 --> 00:02:13,430
And also it's a band behind it.

36
00:02:13,630 --> 00:02:19,720
So instead of just coming to the handles when you are in the pen behind tool you can click and drag

37
00:02:19,720 --> 00:02:20,530
your player.

38
00:02:20,680 --> 00:02:22,960
So you decide for example come to the important.

39
00:02:22,960 --> 00:02:28,210
This is what you usually do and decide exactly where you want it from time to time you want to come

40
00:02:28,210 --> 00:02:29,770
to a certain time.

41
00:02:29,770 --> 00:02:35,120
You only save 15 seconds or so and you decide where your video should be.

42
00:02:35,170 --> 00:02:38,430
15 seconds for example on the transition over here.

43
00:02:38,680 --> 00:02:44,030
So this is the pen behind tool but it's got the composition here.

44
00:02:44,050 --> 00:02:45,700
I have put some keyframes.

45
00:02:45,850 --> 00:02:51,190
Now usually what happens you will draw a shape and you will change the position of the anchor point

46
00:02:51,790 --> 00:02:57,720
and you still in the pan behind tool and you come and click and you say nothing is moving.

47
00:02:57,940 --> 00:02:59,500
Well actually this is a shape player.

48
00:02:59,500 --> 00:03:00,520
It's very long.

49
00:03:00,520 --> 00:03:03,340
It's for the whole content of the composition.

50
00:03:03,340 --> 00:03:06,220
So if you have the pen behind you can't pen anything.

51
00:03:06,340 --> 00:03:07,260
Just one ship.

52
00:03:07,300 --> 00:03:15,760
But if you select a keyframe and use the pen behind to move to the right for example notice it's moving

53
00:03:15,760 --> 00:03:18,970
the keyframe while extending the sheer pleasure.

54
00:03:18,970 --> 00:03:23,540
So the shape that is not cut you have a lot of left or right handers here.

55
00:03:23,650 --> 00:03:24,880
You know what's happening.

56
00:03:25,000 --> 00:03:30,160
If Sellick the first keyframe the same will happen if Selek both of them now actually just moving the

57
00:03:30,160 --> 00:03:34,290
lower left and right with the selection to go.

58
00:03:34,300 --> 00:03:40,870
Now when it comes to videos like this player and I didn't select any keyframe of course I'm panning

59
00:03:40,960 --> 00:03:42,080
left and right.

60
00:03:42,200 --> 00:03:44,690
OK within the content of the video.

61
00:03:44,770 --> 00:03:49,690
Now if I select it keyframe you are not is the keyframe is moving.

62
00:03:49,690 --> 00:03:54,520
And you know some funny things are happening if you don't notice which tool you are using undo under

63
00:03:55,120 --> 00:03:57,640
something as I want to show that I forgot here.

64
00:03:57,970 --> 00:03:59,140
I want to change the color.

65
00:03:59,140 --> 00:04:04,470
First of all here I'm going to take it to blue something that we can see them now.

66
00:04:04,520 --> 00:04:11,230
You'll notice when I pan left and right if I go too much on the right where it is not really the start

67
00:04:11,290 --> 00:04:14,870
of the shape player we started the shape there when we created it.

68
00:04:14,890 --> 00:04:16,300
At this point over here.

69
00:04:16,300 --> 00:04:20,560
So you have these small dots over here are the small oblique lines.

70
00:04:20,650 --> 00:04:23,130
It means this layer has been shifted to the right.

71
00:04:23,470 --> 00:04:26,510
But then at the end here they don't appear OK.

72
00:04:26,900 --> 00:04:33,110
So you will have this kind of oblique nine to tell you that OK you shifted this earlier guys.

73
00:04:33,130 --> 00:04:39,490
So this is how to use the pen behind tool and remember when you selecting keyframe is going to move

74
00:04:39,580 --> 00:04:47,280
the keyframe very practical method when you want to delay and any machine for any kind of shape or video.

75
00:04:47,350 --> 00:04:53,350
By the way everything I talk about here for the shape players or the steel players then it works for

76
00:04:53,350 --> 00:04:57,830
the images OK and even for some of the video techniques will work for images.

77
00:04:57,910 --> 00:04:59,520
But of course you're not going to pan an image.

78
00:04:59,520 --> 00:05:00,260
It doesn't make sense.

79
00:05:00,280 --> 00:05:01,970
It's fixed.

80
00:05:02,030 --> 00:05:05,250
So this is how to use the pen behind tool.

81
00:05:05,530 --> 00:05:12,430
And this is how to change the content of your video when it's in the timeline keeping the time of the

82
00:05:12,430 --> 00:05:14,100
video constant.

83
00:05:14,110 --> 00:05:15,450
I'll see you in the next lecture.
