Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:01,438 --> 00:00:05,438
So we've taken a look at manipulating keyframes in the Dope Sheet,
2
00:00:05,438 --> 00:00:08,437
but what about our animated sequences or movie files?
3
00:00:08,438 --> 00:00:10,983
Well, we can manipulate these as well,
4
00:00:10,983 --> 00:00:14,619
much the same way you would in an editing package,
5
00:00:14,619 --> 00:00:16,437
like Adobe Premier or Avid.
6
00:00:16,438 --> 00:00:17,152
Repositioning, trimming,
7
00:00:17,152 --> 00:00:21,438
or slipping clips becomes a pretty simple task within the Dope Sheet.
8
00:00:21,438 --> 00:00:24,399
So let's get started by taking a look at a clip I've already created.
9
00:00:24,400 --> 00:00:28,990
This is a still frame of the earth that I've added some camera shake to,
10
00:00:28,990 --> 00:00:31,438
and then rendered out as a QuickTime file.
11
00:00:31,438 --> 00:00:34,165
We have the file right here in the Read Node,
12
00:00:34,165 --> 00:00:37,438
and if we hit Play on the timeline, you'll see this animation,
13
00:00:37,438 --> 00:00:39,619
it's just 100 frames of the earth shaking.
14
00:00:39,619 --> 00:00:42,074
Now if we switch over to the Dope Sheet,
15
00:00:42,074 --> 00:00:45,496
you'll see this is the representation of that Read Node.
16
00:00:45,496 --> 00:00:50,438
Back in the Node Graph you see that this is called ReadNode2,
17
00:00:50,438 --> 00:00:56,152
this is ReadNode2, we can call this MasterreadNode to remind us of what that is,
18
00:00:56,152 --> 00:01:01,438
and go back to the Dope Sheet and you'll see that it's
19
00:01:01,438 --> 00:01:03,438
updated here: MasterreadNode Earth_CameraShake.
20
00:01:03,438 --> 00:01:04,438
mov file.
21
00:01:04,438 --> 00:01:06,438
So you'll see here, here are 100 frames.
22
00:01:06,438 --> 00:01:09,188
It starts at frame 0 and it goes to frame 100,
23
00:01:09,188 --> 00:01:13,771
so this is the total frame range of this animation that we're looking at here.
24
00:01:13,771 --> 00:01:17,826
The same way you'd see it in a timeline in an editing
25
00:01:17,826 --> 00:01:20,160
package you may have already used.
26
00:01:20,160 --> 00:01:24,437
Now repositioning this clip is pretty simple, but what is repositioning?
27
00:01:24,438 --> 00:01:27,638
Repositioning is changing the position of a clip,
28
00:01:27,638 --> 00:01:32,438
but it doesn't change the content or the duration of the clip.
29
00:01:32,438 --> 00:01:35,057
So it's important to know that when we're repositioning the clip,
30
00:01:35,057 --> 00:01:37,438
none of the content inside of the QuickTime is changing.
31
00:01:37,438 --> 00:01:40,385
The duration isn't changing, the speed isn't changing,
32
00:01:40,385 --> 00:01:45,385
the ins and the outs aren't changing, and so if we hover over this,
33
00:01:45,385 --> 00:01:48,543
we'll see a plus symbol that the cursor changes to,
34
00:01:48,543 --> 00:01:50,806
and you can just left-mouse button click,
35
00:01:50,806 --> 00:01:53,016
and you can slide this along.
36
00:01:53,016 --> 00:01:57,437
And right now we're changing where the clip appears in the timeline,
37
00:01:57,438 --> 00:02:01,723
just the same way you would in Adobe Premier or in an Avid for example,
38
00:02:01,723 --> 00:02:03,438
and we get these little numbers.
39
00:02:03,438 --> 00:02:06,557
You see a 50 on the left and a 149 on the right,
40
00:02:06,557 --> 00:02:10,687
that's showing you where the new in frame is and where the new out frame is,
41
00:02:10,687 --> 00:02:14,438
and when you release, it's just going to position the clip there.
42
00:02:14,438 --> 00:02:19,165
So if I wind this animation back to the beginning and hit Play,
43
00:02:19,165 --> 00:02:23,188
you'll notice that the earth is just still at the beginning of
44
00:02:23,188 --> 00:02:26,188
the animation because it's just going to fill in these extra 26
45
00:02:26,188 --> 00:02:29,347
frames at the beginning that it doesn't have right now with a
46
00:02:29,347 --> 00:02:33,438
hold frame of the first frame, but we'll talk about that again in a second.
47
00:02:33,438 --> 00:02:37,104
Let's say we want to change the duration of this clip.
48
00:02:37,104 --> 00:02:40,438
So right now the clip is about 100 frames long,
49
00:02:40,438 --> 00:02:43,104
and we want it to be 75 frames,
50
00:02:43,104 --> 00:02:48,438
and we want to take those frames off the front or the back of the clip,
51
00:02:48,438 --> 00:02:49,701
that's what's called trimming.
52
00:02:49,701 --> 00:02:54,438
So if I hover over this and move the mouse over to the left side,
53
00:02:54,438 --> 00:03:02,138
the cursor changes again to this little icon of a frame with an arrow,
54
00:03:02,138 --> 00:03:05,438
and if I left-mouse button click,
55
00:03:05,438 --> 00:03:09,628
the images changes and I can just slide this along and
56
00:03:09,628 --> 00:03:13,437
shorten the duration to what I want it to be.
57
00:03:13,438 --> 00:03:18,390
And it's also important to note that this bar where we've got the
58
00:03:18,390 --> 00:03:23,580
cursor placed gets a little sticky to make it easier for us to know
59
00:03:23,580 --> 00:03:26,438
where we want to put our frame ranges.
60
00:03:26,438 --> 00:03:28,818
So in affect what we've done is we've removed these
61
00:03:28,818 --> 00:03:32,750
frames from the beginning of the clip, and if we hover back over this,
62
00:03:32,750 --> 00:03:38,438
we can just bring those frames back by sliding it the other way.
63
00:03:38,438 --> 00:03:42,090
Likewise at the end of the clip,
64
00:03:42,090 --> 00:03:50,437
the cursor's going to change and we can just grab the end and cut it in,
65
00:03:50,438 --> 00:03:52,688
and then release where we want it to be.
66
00:03:52,688 --> 00:03:55,188
So now if we set this back to the beginning,
67
00:03:55,188 --> 00:04:00,287
we can see that the entirety of the animation is now only about 75 frames long.
68
00:04:00,287 --> 00:04:00,637
Now,
69
00:04:00,637 --> 00:04:04,665
it's important to know that we did not change the speed
70
00:04:04,665 --> 00:04:07,119
of the animation within this clip,
71
00:04:07,119 --> 00:04:12,437
all we did within this clip was trim off the last 25 frames.
72
00:04:12,438 --> 00:04:16,597
So I'll go ahead and set this back to its full frame range.
73
00:04:16,597 --> 00:04:21,338
Now the next thing that we can do here is we can slip the clip,
74
00:04:21,338 --> 00:04:23,438
and if you haven't slipped something before,
75
00:04:23,438 --> 00:04:28,074
what that means is we're just going to change the content of the
76
00:04:28,074 --> 00:04:32,438
clip without changing the position or the duration.
77
00:04:32,438 --> 00:04:36,528
So it's kind of the opposite of repositioning your clip.
78
00:04:36,528 --> 00:04:43,785
So if I move the current frame to 50, and we see that this is the current frame,
79
00:04:43,785 --> 00:04:49,264
so I'm going to trim 25 frames off of the front of this clip,
80
00:04:49,264 --> 00:04:54,104
and I'm going to trim 25 frames off of the back of this clip,
81
00:04:54,104 --> 00:04:57,437
and if you hover over the bottom of the clip,
82
00:04:57,437 --> 00:05:00,888
you'll see this icon and this is the slip icon.
83
00:05:00,888 --> 00:05:02,988
And we can left-mouse button click,
84
00:05:02,988 --> 00:05:07,122
and we can just change what's happening inside of that range
85
00:05:07,122 --> 00:05:09,648
without actually moving the clip itself.
86
00:05:09,648 --> 00:05:15,580
So we know that the animation that we want will have to occur in
87
00:05:15,580 --> 00:05:19,009
our timeline between frame 25 and frame 75,
88
00:05:19,009 --> 00:05:23,543
but we want to change the content inside that frame range,
89
00:05:23,543 --> 00:05:29,437
and you just do it by slipping the clip inside that frame range with that icon.
90
00:05:29,438 --> 00:05:32,301
So I'm going to set that back to normal,
91
00:05:32,301 --> 00:05:36,437
and now let's take a look at how it's filling in blank frames.
92
00:05:36,438 --> 00:05:40,698
So, if I trim this clip, if I take away the first 50 frames,
93
00:05:40,698 --> 00:05:43,771
and I hit Play from the beginning of this animation,
94
00:05:43,771 --> 00:05:46,104
you'll see that the animation is still,
95
00:05:46,104 --> 00:05:49,104
and that's because there's a hold of the first
96
00:05:49,104 --> 00:05:50,701
frame through these missing frames.
97
00:05:50,701 --> 00:05:55,438
So the computer's saying, these frames are missing, what do I fill them in with?
98
00:05:55,438 --> 00:05:57,619
I'll just hold the first frame of animation.
99
00:05:57,619 --> 00:06:01,818
Now if we look at the properties for this Read Node here on the right,
100
00:06:01,818 --> 00:06:05,628
you'll see that this is the new frame range: 50,
101
00:06:05,628 --> 00:06:09,438
you see that moves when I slide the trimming marker,
102
00:06:09,438 --> 00:06:11,437
and the end frame is 100.
103
00:06:11,437 --> 00:06:15,104
Now these little dropdown menus give you a couple of different
104
00:06:15,104 --> 00:06:17,574
options on what to do with the help frames.
105
00:06:17,574 --> 00:06:20,756
So right now we're just holding the first frame to fill in the blanks,
106
00:06:20,756 --> 00:06:22,130
but we can pick black instead,
107
00:06:22,130 --> 00:06:24,437
and it's going to fill those blank frames with black.
108
00:06:24,438 --> 00:06:28,742
We can pick a loop or we can pick a bounce,
109
00:06:28,742 --> 00:06:30,698
and what a bounce is,
110
00:06:30,698 --> 00:06:34,199
the computer is filling in the information by bouncing
111
00:06:34,199 --> 00:06:36,866
back from the frames that it has.
112
00:06:36,866 --> 00:06:41,438
So, what it will do is since we started at frame 50,
113
00:06:41,438 --> 00:06:46,238
what it's going to do is it's going to take frame 50 and play frames backwards
114
00:06:46,238 --> 00:06:50,438
through the missing frame range until it gets to frame 0.
115
00:06:50,438 --> 00:06:56,438
So it's just taking this clip, flipping it, and laying it in here backwards.
116
00:06:56,438 --> 00:06:57,392
Loop is similar.
117
00:06:57,392 --> 00:06:59,301
If we set this to loop,
118
00:06:59,301 --> 00:07:03,738
what it's doing is it's taking this clip and it's filling in these missing
119
00:07:03,738 --> 00:07:07,038
frames with what would happen at the end of the animation,
120
00:07:07,038 --> 00:07:10,392
it's just taking a copy of this and starting it again
121
00:07:10,392 --> 00:07:12,301
at the beginning of this animation.
122
00:07:12,301 --> 00:07:15,483
So if I set the end to loop, for example,
123
00:07:15,483 --> 00:07:19,614
and we play through, it's just going to loop the animation forever,
124
00:07:19,614 --> 00:07:21,026
and forever, and forever,
125
00:07:21,026 --> 00:07:25,938
and forever because it's just taking extra copies of this animation
126
00:07:25,938 --> 00:07:30,438
and pasting it in here invisibly every 50 frames.
127
00:07:30,438 --> 00:07:34,771
I prefer to work with black because that way if I have missing
128
00:07:34,771 --> 00:07:37,437
frames in a production that I'm working on,
129
00:07:37,438 --> 00:07:43,438
black frames will show up, and then you know that there is a mistake or an error.
130
00:07:43,438 --> 00:07:48,437
Sometimes I will use loop and bounce if I'm just trying to cheat the animation.
131
00:07:48,438 --> 00:07:51,580
You'll notice that right now I only have 50 frames out
132
00:07:51,580 --> 00:07:53,295
the 100 frames of this animation,
133
00:07:53,295 --> 00:07:57,753
but because all of our animation is just bouncing and wiggling,
134
00:07:57,753 --> 00:08:05,074
you really don't notice a hitch when we cross over from 49 frames to 50 frames,
135
00:08:05,074 --> 00:08:08,756
but there is a little bit of a hitch.
136
00:08:08,756 --> 00:08:16,037
Likewise, if we do the bounce, there's going to be a little bit of a hitch too,
137
00:08:16,037 --> 00:08:16,487
hitch,
138
00:08:16,487 --> 00:08:21,437
and sometimes you can get away with lengthening animation by just
139
00:08:21,438 --> 00:08:24,295
adding some frames that are loops or bounces in there,
140
00:08:24,295 --> 00:08:25,437
don't recommend it though.
141
00:08:25,438 --> 00:08:28,438
But it's just something to keep in mind when you're working on these things.
142
00:08:28,438 --> 00:08:34,003
Now we can also keep our comp clean by using the Time Offset Nodes and the
143
00:08:34,003 --> 00:08:37,710
Frame Range Nodes to do what I've been showing you here.
144
00:08:37,710 --> 00:08:41,528
This is kind of a quick and dirty way of trimming or
145
00:08:41,528 --> 00:08:46,046
editing clips inside of the Dope Sheet, but if you want to keep your comp clean,
146
00:08:46,046 --> 00:08:49,437
you would use a Time Offset and a Frame Range Node to perform
147
00:08:49,438 --> 00:08:55,438
these operations in a non-destructive way.
148
00:08:55,438 --> 00:09:06,438
So, we'll take a look at those in the upcoming clips.
