AE_animation Loop Expression tip _動畫循環表達式

Hello,guys,Today i want to show you the tip about the Loop express of the After Effect. It's a piece cake and useful !

So, let's go ahead and start looking !

大家好，今天我要秀一個有關AE LoopExpress的訣竅，相當簡單。好，我們接下看吧!

__0.First, Make a Loop animation

       首先做一個循環動畫  

__1.Alt-click the time-Vary stop watch icon. It'll show up the Expression.

      按住Alt並點一下時鐘標示，它就會出現Expression

__2.Click the play icon. choice Property -> LoopIn ~~~ LoopOut~~. Let's take look them. What are          their effect ?

       點擊play標示，選擇 Proerty，就會看到Loop系列的Expression.我們看看他們的效果是甚            麼?

 __3. LoopIn : It's mean red range is effected by LoopIn , include the keyframes.

        LoopIn : 圖中的紅色區域是有作用的，包含Keyframe

__4.LoopOut : It's mean red range is effected by LoopOut, include the keyframes.

       LoopOut : 圖中的紅色區域是有作用的，包含Keyframe

__5.LoopInDuration : It's mean red range is effected by LoopInDuration, dose not include the key                                            frame. You can change the value of the duration which should be less than                                              zero.

      LoopInDuration : 圖中的紅色區域是有作用的，不包含Keyframe，你可更改Duration的數值,                                     要小於0.

__6.LoopOutDuration : It's mean red range is effected by LoopOutDuration, dose not include the key                                        frame. You can change the value of the duration which should be less than                                               zero.
       LoopOutDuration : 圖中的紅色區域是有作用的，不包含Keyframe，你可更改Duration的數                                          值, 要小於0.

It's pretty easy, right ? Try it !

很簡單對吧? 試試看吧!
