1
00:00:01,230 --> 00:00:04,560
This lecture guys I will introduce you to the null object.

2
00:00:04,560 --> 00:00:08,530
How to apply it how to use it and mainly how to use it as a parent.

3
00:00:08,670 --> 00:00:13,200
I'm going to keep everything very simple here for you to understand the concept is practically very

4
00:00:13,200 --> 00:00:19,620
easy but going on in the course and editing your work you will notice that there is no substitute for

5
00:00:19,620 --> 00:00:21,120
the null object.

6
00:00:21,300 --> 00:00:24,580
When you're working with 3-D and certain effects.

7
00:00:24,930 --> 00:00:31,750
If you want to follow along with me please open the project file not object dash start AP.

8
00:00:31,910 --> 00:00:32,780
Let's explore it a bit.

9
00:00:32,780 --> 00:00:34,590
What's the null object is all about.

10
00:00:34,700 --> 00:00:38,430
We are going to focus on the composition one for now.

11
00:00:38,570 --> 00:00:44,480
If you play a comp I have here four squares that are rotating on that and on and can point.

12
00:00:44,480 --> 00:00:50,720
Now let's imagine I want to create a group animation for the four squares over here without losing the

13
00:00:51,140 --> 00:00:52,620
animation for each square.

14
00:00:52,910 --> 00:00:55,380
Well what comes to mind is parenting.

15
00:00:55,580 --> 00:00:58,260
But actually I don't have a leg to parent to.

16
00:00:58,460 --> 00:01:05,330
This is why a null object exists when you don't have any letter to parent to you will create a new object

17
00:01:05,990 --> 00:01:07,190
to create an object.

18
00:01:07,190 --> 00:01:08,400
Very simple you.

19
00:01:08,440 --> 00:01:15,740
You go to new and you say an object and that object has been created for you in the cup.

20
00:01:15,850 --> 00:01:20,860
Actually this object will become invisible when you render as long as you are previewing it will be

21
00:01:20,860 --> 00:01:21,730
visible for you.

22
00:01:21,730 --> 00:01:23,050
Otherwise you will lose it.

23
00:01:23,560 --> 00:01:30,130
And in the timeline line here a layer has been created with the transformation of in normal layer in

24
00:01:30,130 --> 00:01:34,530
the solids here a solid has been created that is called nulled 3.

25
00:01:34,570 --> 00:01:37,480
So actually an object is a solid layer.

26
00:01:37,570 --> 00:01:44,160
It's being created as a null object you don't have a switch here to switch any layer to it not so obviously

27
00:01:44,170 --> 00:01:46,540
to work with a null object you need to use a parent.

28
00:01:46,570 --> 00:01:52,060
For now I'm making it very simple and I knew that this is going to be more complicated and very nice

29
00:01:52,060 --> 00:01:52,790
by the way.

30
00:01:53,170 --> 00:01:59,050
So I select this for layers here and parent them to the null object you've seen this in the previous

31
00:01:59,050 --> 00:02:00,010
lectures.

32
00:02:00,160 --> 00:02:06,880
And by virtue of the parenting position skill rotation animations on the three will also be applied

33
00:02:06,970 --> 00:02:07,650
on the other.

34
00:02:07,640 --> 00:02:13,630
There's a simple animation that you can see here is the rotation for example fact electorate that I

35
00:02:13,690 --> 00:02:20,680
would select everything to see the anchor points if I wrote that you notice that all four letters are

36
00:02:20,690 --> 00:02:24,100
rotated according to the anchor point of the non-ladder.

37
00:02:24,360 --> 00:02:24,590
OK.

38
00:02:24,610 --> 00:02:28,460
This is very practical because later on the knowledge will be invisible.

39
00:02:28,600 --> 00:02:32,460
So you're really creating without any visible parent.

40
00:02:32,710 --> 00:02:34,930
So let's create a very simple animation here.

41
00:02:34,930 --> 00:02:39,410
This is parenting you know with very well I'm sure because of the previous lectures.

42
00:02:39,460 --> 00:02:46,130
So could that by now some students will ask why I didn't create a teacup.

43
00:02:46,260 --> 00:02:50,840
Well I did not create a precompile to demonstrate to you the use of the null object.

44
00:02:50,840 --> 00:02:51,460
OK.

45
00:02:51,570 --> 00:02:53,860
So I would go to none too.

46
00:02:54,030 --> 00:03:00,880
That too has more layers and I want to create a common animation for all these layers.

47
00:03:00,900 --> 00:03:06,000
Of course you can compose but slowly slowly you will learn that an object is a bit more powerful than

48
00:03:06,100 --> 00:03:08,380
recomposing just at the beginning.

49
00:03:08,640 --> 00:03:15,750
So let's create a new object our right click go to new and then go to an object video or another NULL

50
00:03:15,750 --> 00:03:20,110
has been created not just for every dollar you will get a solid layer.

51
00:03:20,520 --> 00:03:21,640
Let's take all the layers.

52
00:03:21,630 --> 00:03:26,300
Of course bind them to the null object and create a very simple animation.

53
00:03:26,430 --> 00:03:30,310
I will open the transform of the not object here.

54
00:03:30,660 --> 00:03:36,750
For example after half a second I will keyframe the position the scale and the rotation.

55
00:03:36,750 --> 00:03:40,820
After some time I would like them to rotate.

56
00:03:40,910 --> 00:03:46,220
OK so I them minus 90 and also I would like to get them down.

57
00:03:46,380 --> 00:03:48,020
OK just like parenting.

58
00:03:48,180 --> 00:03:49,200
I want to keep them here.

59
00:03:49,210 --> 00:03:54,110
Out keyframe also the position I'm going to keep them here for half a second.

60
00:03:54,300 --> 00:03:54,940
OK.

61
00:03:55,160 --> 00:03:56,790
Duplicate all the keyframes.

62
00:03:56,790 --> 00:04:01,980
Here you are then after one second I would like them to come just over here.

63
00:04:01,980 --> 00:04:05,640
I'm going to move the position OK very far.

64
00:04:05,970 --> 00:04:09,140
Then after one second or less as you wish.

65
00:04:09,180 --> 00:04:12,200
Take them all out using the position here.

66
00:04:12,450 --> 00:04:13,080
OK.

67
00:04:13,350 --> 00:04:20,440
So actually I grouped these layers through a single animation using the parent and the Null-A the benefited

68
00:04:20,540 --> 00:04:24,510
the Null-A is invisible and it's really under your control.

69
00:04:24,860 --> 00:04:25,210
Fine.

70
00:04:25,230 --> 00:04:27,360
Let's play the animation is simple.

71
00:04:27,360 --> 00:04:30,780
They churn that comes out and they got.

72
00:04:30,780 --> 00:04:37,920
Now what is more important here that using the non-Labor you can start breaking of course the parenting

73
00:04:38,070 --> 00:04:40,950
which is now much higher controlled than a pre-camp.

74
00:04:41,100 --> 00:04:45,970
For example let's take the rectangle here and come at a certain time.

75
00:04:46,050 --> 00:04:47,870
When it comes over here.

76
00:04:48,100 --> 00:04:54,590
OK let's open the keyframes And let's take the rectangle and of course you know now control shift d

77
00:04:55,070 --> 00:04:59,730
d on the Mac to split the land so you can remove the parenting.

78
00:04:59,730 --> 00:05:00,630
Here you are.

79
00:05:00,840 --> 00:05:08,910
Now let's say you bring up the position of press B shift as full scale and shift our for rotation keyframe

80
00:05:08,940 --> 00:05:09,680
all of them.

81
00:05:09,830 --> 00:05:10,330
OK.

82
00:05:10,590 --> 00:05:13,310
And then come after let's say one second here.

83
00:05:13,530 --> 00:05:17,930
Let's go to the line and the line in the middle of the letter.

84
00:05:18,330 --> 00:05:18,890
OK.

85
00:05:18,900 --> 00:05:24,030
Bring back the rotation to zero and bring back the scale to 100 percent.

86
00:05:24,060 --> 00:05:26,780
And here you are you'll have a very nice animation.

87
00:05:26,970 --> 00:05:27,940
Quite simple.

88
00:05:28,140 --> 00:05:31,860
So you learn a bit about the concept of the null object.

89
00:05:31,860 --> 00:05:37,590
Later on we develop on this subject and with practice you will get to know when to compose and when

90
00:05:37,590 --> 00:05:42,400
to use the null object is certain animations effects and 3D.

91
00:05:42,450 --> 00:05:46,020
There is no way to compose you have to use the null object.

92
00:05:46,020 --> 00:05:47,360
Thank you very much for listening.

93
00:05:47,400 --> 00:05:48,940
I will see you in the next lectures.
