在After Effects中实现径向擦拭式动画

Animate an elypse shape with radial wipe in After Effects ✔

嗨 欢迎收看今日教程
Hey there and welcome today.
我们常有一些复杂的教程
So we always have those complicated tutorials.
却没有基础的教程
But we don’t have the basic ones,
例如 如何使一个圆成为动画?
for example, how do animate a circle?
我将继续 马上为你展示
I will just go ahead and show it to you very quickly.
选择配色方案
So I’ll select the color scheme.
我按“Ctrl+Y”来创建背景
I press ctrl Y to create a background.
选择这里拥有颜色的其中一种
I will select one of the colors I have here.
比如说 这个蓝色的看起来很酷
For example, this blue one looks cool.
继续 我点击这里
And I’ll go ahead, I click here.
下层选项的椭圆工具
I drop down to the ellipse tool.
同时按“Shift”键
And with my shift key,
选择(此处)并创建一个圆
I select and create a circle.
现在点击形状图层
Now I click on the shape layer.
指向菜单“窗口”
I want to go to window.
打开“对齐”
I want to open align,
因为我想要把这个圆居中对齐
because I would like to align this circle in the middle.
我按水平居中 垂直居中 好的
So I align it middle, middle, ok.
我还可以移动锚点
I can even move the anchor point.
移动锚点应同时按“Y”键
Anchor point should be with my Y key minute.
选工具栏 然后我的画笔 这里应居中
With my pen behind tool, this should be in the middle.
好的 我得到一个完美的圆形
Okay, I have a perfect circle.
现在我意识到没有填充色
Now I realize I have no fill,
点击“填充”
so I click on the fill.
从我的配色方案小窗口中选择一种颜色
And I select one of the colors from my little color scheme here.
好了 我们来看看粉红色的
Okay, let’s go with the pink ones.
我不需要描边 点击“描边”
And I do not want stroke, I click stroke.
选择“None”
I select none.
好的 这是我的第一个圆
Okay, so this is my first circle.
如何让它动起来?
How do I animate it?
点击选定它
I click on it.
我选择了一个叫做径向擦除的效果
I select an effect which is called radial wipe.
你应该记住这个效果
You should remember this effect,
因为它真的很有用而且很酷
because it’s really useful and cool.
我把它向下展开 你可以看到我的效果控制面板
I just drop it down and you can see in my effect controls panel.
我仍然可以回到我的专栏
I can still go back to my columns of course,
但是我想要效果控制面板
but I want my effect controls panel.
如果我像这样实现过渡
If I make the transition completion like that,
我就得到了这个动画
I’ll get this animation.
起初 让我们就从100%开始
And let us start from 100% at the beginning.
我会从那开始
I will key from that.
动画时间大概为两秒钟
And I go to about maybe two seconds.
这里设置为0
And I make it zero.
因此这个动画需要两秒钟来播放
Okay, so this animation will take two seconds to play.
如果你想多做一些
Now if you want to make more of them,
我建议首先调整关键帧
I suggest we first adjust the keyframes.
点击形状图层
Click on the shape layer
然后按“U”键来显示关键帧
and press U to reveal the keyframes.
选择两个(关键帧)
I will select both,
右击“关键帧助手” 选择“减少帧数”
I right click keyframe assistant and I ease them in.
动画看起来好一点
So the animation looks a bit nicer.
通过点击此处图片编辑器 我就可以确切地检查效果
I can check exactly how nice by clicking here to the graph editor.
好的 我们得到了像那样的动画
Okay, we have an animation like that.
如果你想看另一个图
If you’ll see another graph,
可以在它们之间切换
you can switch between them,
在值和速度图之间
between the value and speed graph.
这是值图 这是速度图
This is the value graph, this is the speed graph.
好的 我点击左边的点
Okay, I click the left point
把它拖向中间
and I drag it to the middle,
这个也拖到中间
and this one to the middle.
现在动画会变缓慢 然后变快
Okay, now the animation will go slower, then quicker,
然后结尾处变慢
then slower at the end. Boop.
好的 我认为这是一个非常流畅的美好动画
Okay, I think this is a really fluid and nice animation.
任何你想改变的东西
And anything you want to change,
比如说 复制这个圆
you just for example, duplicate the circle,
按“S”键
you press s.
因为锚点正好在中心
And since the Anchor Point is exactly in the middle,
它能适当地等比例放大
it will scale properly.
好吧 我像这样操做
Okay, I’ll make it like that,
然后我想返回到Adobe配色方案
then I want to go back to my Adobe color scheme.
我想选择我自定义的不同颜色
I want to select myself, my different colors.
好的 我还要确保这是第二个的圆
Okay, I need to also make sure that this will be the second one.
因为我想把它放在第一个圆的底层
Because I wanted to have it under it.
我已经用百分比来做了
Okay, I’ve overdone it with the percentage.
好的 (预览效果)
Okay, bop.
它将会更酷让我关闭图形编辑器
It will be even cooler, let me close the graph editor.
如果我想使其更进一步
If I place this more forward,
选择“alt”键 同时按“下一页” “下一页” “下一页”
so I select alt key and page down, page down, page down.
好的
Okay.
我加的音效也很酷
Okay, my additional sound effects are really cool.
我同样做 按下“S”键
Okay, so I can do the same, I press s.
我避开最久的那个圆 再次显现最底层的那个圆
I make the farthest one away, the most on the bottom side again.
再大一点 选择填充
A bit bigger, I select fill,
再一次改变它的颜色为自定义肤色的一种
I change its color again to one of my color skin things.
我觉得太大了
I think I made it too big
老办法 下一页 下一页 下一页
and old, page down, page down, page down.
一个较小的副本 使其为最后(最底层)一个
One less duplication, make it the last,
让它成为最大的圆
make it the biggest one.
改变其为我们实际想要的颜色也许我们想要
Change the color what do we actually want here, maybe we want.
要用粉色
Okay, we have to use the pink one
我认为此处要用相同的颜色
and I think I have to the same colors here.
这是我的小错误
This is my little mistake. Okay, so.
我选择了一种粉红色的配色方案
Well, I selected a color scheme with just pink colors.
好了 让它变成一 二 三
Okay, let it be one two three, bop.
这是你的整个动画
And this is your entire animation.
这种方式 你就做出像这样的圆(动画)
This way, you would make a circle like that.
好的 让我把它关掉
Okay, let me close that down,
它会去在这里 我按”U“键
it will go to about here I press U.
动画在这里结束
Okay, the animation end here.
当然你也可以做出不同的进化
And you can of course make different evolutions.
你可以让动画有不同的效果
You can make the animation ever different.
但基本上 如何准备这样的动画
But basically, this is the simplest way
这是最简单的方式
how you can prepare an animation like this.
