00:00:01,569 --> 00:00:06,235
In this clip, we'll take a look at displaying curves in the Curve Editor,
2
00:00:06,235 --> 00:00:09,042
hiding and un-hiding animation, zooming in and out,
3
00:00:09,042 --> 00:00:10,516
panning around, relative framing,
4
00:00:10,516 --> 00:00:14,568
and resetting the pan and zoom in case you get lost.
5
00:00:14,569 --> 00:00:18,114
So I wanted to just take a moment here to point out that
6
00:00:18,114 --> 00:00:20,841
this is a hierarchy that has little twisties that usually
7
00:00:20,841 --> 00:00:22,478
show up as plus or minuses,
8
00:00:22,478 --> 00:00:26,569
and if a value is collapsed like this with a plus and you select it,
9
00:00:26,569 --> 00:00:29,997
all of the curves for all of the values inside of that
10
00:00:29,997 --> 00:00:32,568
attribute will show up here on the Curve Editor.
11
00:00:32,569 --> 00:00:34,809
Likewise, if we click on this plus button,
12
00:00:34,809 --> 00:00:36,489
and we go into this value,
13
00:00:36,489 --> 00:00:40,735
we see that it has an X and a Y value that both have keyframes.
14
00:00:40,735 --> 00:00:45,693
So on either one of these we can just select the X to see the X curve,
15
00:00:45,693 --> 00:00:48,750
or we can select the Y to see the Y curve,
16
00:00:48,750 --> 00:00:51,205
or if we select their parent node, the Translate,
17
00:00:51,205 --> 00:00:54,968
like we did at the beginning, we see both curves together.
18
00:00:54,968 --> 00:01:00,568
So it's just something to keep in mind with how this hierarchy system works.
19
00:01:00,569 --> 00:01:05,235
So if I click in here to deselect these curves and I want to
20
00:01:05,235 --> 00:01:08,841
create a consecutive list of attributes or curves that I want
21
00:01:08,841 --> 00:01:10,750
to show in the Curve Editor,
22
00:01:10,750 --> 00:01:14,250
I can hold down Shift on the keyboard and just select
23
00:01:14,250 --> 00:01:16,134
the curves that I want to appear,
24
00:01:16,134 --> 00:01:18,742
and I could just continue going down the line holding
25
00:01:18,742 --> 00:01:20,568
the Shift button to add these curves.
26
00:01:20,569 --> 00:01:20,919
Likewise,
27
00:01:20,919 --> 00:01:25,118
you can hold the Ctrl button if you want to unselect some
28
00:01:25,118 --> 00:01:28,786
of these curves on an individual basis and remove or add
29
00:01:28,786 --> 00:01:30,308
them to your selection set.
30
00:01:30,308 --> 00:01:35,568
You can also display an audio file in here just like we did in the Dope Sheet.
31
00:01:35,568 --> 00:01:39,902
So if you have an AudioRead Node or a Read Node with audio
32
00:01:39,902 --> 00:01:42,919
data in it ready to go in your comp,
33
00:01:42,919 --> 00:01:48,518
what you can do is you can right-click in the Curve Editor and navigate to View,
34
00:01:48,518 --> 00:01:54,274
then to Audio, then to Draw Style, and check this box below on,
35
00:01:54,274 --> 00:01:57,568
and your wave form will appear below.
36
00:01:57,569 --> 00:02:02,098
Likewise, you can go back to the same menu by right-clicking,
37
00:02:02,098 --> 00:02:04,568
going to View, Audio, Draw Style,
38
00:02:04,569 --> 00:02:08,568
and selecting off to just get rid of that audio if you don't want it visible.
39
00:02:08,568 --> 00:02:10,568
Now to zoom in and out of the Curve Editor,
40
00:02:10,568 --> 00:02:13,368
you can click on the area you'd like to zoom into and hit F
41
00:02:13,368 --> 00:02:15,333
on the keyboard to frame that selection.
42
00:02:15,333 --> 00:02:18,568
This is a great hotkey that I use all the time.
43
00:02:18,569 --> 00:02:21,699
So if I marquee select these keyframes, for example,
44
00:02:21,699 --> 00:02:26,569
and hit F on the keyboard, it's going to jump me right to it.
45
00:02:26,569 --> 00:02:30,932
Likewise, you can just use the scroll button on your mouse to scroll in and out,
46
00:02:30,932 --> 00:02:35,023
and that will zoom out or zoom in based on the way that you're scrolling.
47
00:02:35,023 --> 00:02:40,308
Another thing to know is on the keyboard if you have a plus and a minus button,
48
00:02:40,308 --> 00:02:45,525
you can use plus and minus to just zoom in and zoom
49
00:02:45,525 --> 00:02:48,569
out on a very fine detail level.
50
00:02:48,569 --> 00:02:51,804
Now let's say you get stuck because you're really in a
51
00:02:51,804 --> 00:02:53,568
fine granular view of this thing.
52
00:02:53,569 --> 00:02:55,876
So if I select these things and I hit F,
53
00:02:55,876 --> 00:02:58,645
and I'm deep in here and I don't know where I am,
54
00:02:58,645 --> 00:03:02,997
and I can't find my curves, and you want to reset the view,
55
00:03:02,997 --> 00:03:07,568
to reset the zoom or pan, just right-click on the Curve Editor,
56
00:03:07,569 --> 00:03:10,235
select View, and then select Frame All.
57
00:03:10,235 --> 00:03:15,568
And Frame All will jump you back out to view all of your keyframes.
58
00:03:15,569 --> 00:03:20,134
Keep in mind that this view will only give you a view of your curve
59
00:03:20,134 --> 00:03:22,569
from its first keyframe to its last keyframe.
60
00:03:22,569 --> 00:03:25,200
It won't give you anything beyond because it's just assuming
61
00:03:25,200 --> 00:03:28,968
that you want to work with the keyframes that you have at hand
62
00:03:28,968 --> 00:03:31,068
when you're in the Curve Editor.
63
00:03:31,068 --> 00:03:34,568
Now this function also has a hotkey that's really nice,
64
00:03:34,569 --> 00:03:37,777
so just like we use the F button to zoom in,
65
00:03:37,777 --> 00:03:40,402
and if we're in here and we get lost,
66
00:03:40,402 --> 00:03:43,134
instead of having to right-click and go to these menus,
67
00:03:43,134 --> 00:03:46,525
what you can do is you can just hit A on the keyboard,
68
00:03:46,525 --> 00:03:49,969
and that's easy to remember because you're hitting A to view all.
69
00:03:49,969 --> 00:03:54,319
Both of these hotkeys have been lifesavers for me in the past so I hope that
70
00:03:54,319 --> 00:03:56,569
you put them in your toolbox and use them quite a bit.
71
00:03:56,569 --> 00:04:00,047
There are two ways that you can pan the editor: one is by holding down the
72
00:04:00,047 --> 00:04:02,268
Alt button on your keyboard and by left-mouse dragging.
73
00:04:02,268 --> 00:04:06,818
So if I hold down Alt on my keyboard and left-mouse button click,
74
00:04:06,818 --> 00:04:13,013
I can just pan around in here and see exactly where I need to go.
75
00:04:13,013 --> 00:04:16,569
Likewise, you can just middle-mouse button and drag,
76
00:04:16,569 --> 00:04:18,655
and that will pan the viewer as well.
77
00:04:18,655 --> 00:04:19,699
So in this clip,
78
00:04:19,699 --> 00:04:23,140
I just wanted to take a minute to point out the different ways
79
00:04:23,140 --> 00:04:25,426
to pan and zoom inside the Curve Editor,
80
00:04:25,426 --> 00:04:29,932
how to jump to specific frames, and how to reset your view if you get lost,
81
00:04:29,932 --> 00:04:31,841
which believe me, happens quite a bit.
82
00:04:31,841 --> 00:04:33,205
Now in the next clip,
83
00:04:33,205 --> 00:04:36,513
we'll take a look at editing these curves by adding
84
00:04:36,513 --> 00:04:40,013
and removing points to the curve, moving the points,
85
00:04:40,013 --> 00:04:43,042
and how copying and pasting points works inside of these curves.
86
00:04:43,042 --> 00:04:45,569
We'll also take a look at how you can sketch an animation
87
00:04:45,569 --> 00:04:57,569
curve right in the Curve Editor instead of having to lay out
88
00:04:57,569 --> 00:05:02,569
keyframes in the parameter window.
