插件名稱：Sapphire

效果名稱：s_shake

效果所屬: Sapphire Distort

效果應用：畫面搖擺、抖動；動態(tài)模糊；視頻分屏（極端應用）

官方Manual內(nèi)的解釋：

Applies a shaking motion to the source clip over time with translation, zooming, and/or rotation. The shaking is random but repeatable, so with the same parameters the same shaking motion is generated each time. Turn on Motion Blur and adjust the Mo Blur Length for different amounts of blur. Adjust the Amplitude and Frequency for different shaking speeds and amounts. The Rand parameters give detailed control of the random non-periodic shaking, and the Wave parameters adjust the regular periodic shaking. The X, Y, Z, and Tilt parameters control the horizontal, vertical, zoom, and rotation amounts of shaking respectively.

翻譯過來就是：（機翻改了下 人比較懶）

s_shake效果是隨著時間的推移，通過平移、縮放和/或旋轉(zhuǎn)將抖動運動應用于源剪輯。抖動是隨機但可重復的，因此使用相同的參數(shù)，每次都會生成相同的抖動運動。啟用“運動模糊”（Motion Blur），并調(diào)整“模糊長度”（Mo Blur Length）以獲得不同的模糊量。針對不同的振動速度和振動量調(diào)整振幅和頻率。Rand參數(shù)對隨機非周期性抖動進行了詳細控制，Wave參數(shù)調(diào)整了規(guī)則周期性抖動。X、Y、Z和傾斜參數(shù)分別控制抖動的水平、垂直、縮放和旋轉(zhuǎn)量。

某度翻譯什么時候這么智能了

簡單點說這就是這是一個用來做視頻抖動的效果，而這個抖動是有規(guī)律的，可以擬合成一個周期性函數(shù)，我們可以通過改各種不同的數(shù)值來去有規(guī)律地控制抖動的各種參數(shù)來實現(xiàn)我們想要的效果

同時插件自帶動態(tài)模糊和平面追蹤 好耶

下面我將從參數(shù)列表來具體說明。

參數(shù)列表以及翻譯

我們從上往下看

加載和儲存預設(shè)暫且不提

Style 三種模式

????-Normal 標準

????-Twitchy 抽動

????-Jumpy 躍動

顧名思義，在標準模式下晃動最為緩和，抽動模式則可以模擬一些痙攣向的效果，速度曲線最為陡峭，躍動我個人沒看出與標準模式太大的差別，但總體來說會抽地更干脆一點（literally!）

用圖來大概表示其中的關(guān)系吧：

紅線是Normal，藍線是Jumpy，而紫線則為Twitchy

Edit Mocha 調(diào)整追蹤蒙版

不解釋，點擊這個會跳轉(zhuǎn)到Boris FX的Mocha軟件，脫離Pr/Ae之外了，UI不好看不想研究（就是懶）

Mocha 追蹤（蒙版）

同樣不解釋，只想入門跳過這里

Combine Masks 蒙版結(jié)合

????-Union 均取

????-Intersect 取交集

????-Mocha Only 僅追蹤

Amplitude 基準振幅

范圍：[0,inf)

控制全局震動幅度，與X/Y/Z軸的振幅相乘

Frequency 基準頻率

范圍：[0,inf)

控制全局的震動頻率，與X/Y/Z/Tilt軸的頻率相乘

Phase 基準相位延遲

范圍:(-inf,inf)

這個搖擺的效果，本質(zhì)上是一個形如y=A sin (Bx+C) 的三角函數(shù)；

相位控制的是C，振幅控制的是A，頻率控制的是B；

如果你沒有學到高中數(shù)學，可以簡單把C理解為一開始第一次震動的延遲時間。

也許你看到上面三個可能一時半會不能理解，其實很簡單，無論你有沒有學過三角函數(shù)，請看下圖：

右邊的紅線就是我們的函數(shù)圖像，在這里紅線越高，我們晃動的速度也就越高，紅線為負數(shù)的時候，我們視頻內(nèi)容晃動的方向就是相反的，就像一個鐘擺一樣做著簡諧運動

還是不理解？沒關(guān)系，我們把幾個數(shù)值調(diào)一調(diào)看一下：

這是把A從1調(diào)到10的結(jié)果，可以很明顯的看出來紅線最高的地方從前一張圖的1變成了10，而最低從-1變成了-10

這里的A，控制圖像最高和最低地點的，也就是控制視頻晃動的最大速度的A，就是前文講的Amplitude，振幅

換句話說，在這里比起一開始的圖像，圖像每個地方的縱軸數(shù)值都乘上了一個10

然后是Frequency，頻率：

和Amplitude很像，只是一個是縱向一個是橫向

我們把B從1改成0.1，函數(shù)也就被拉寬了不少，本來圖像里紅線第二次在縱軸上碰到0的時間是3.14（π），但因為我們把速度從1改成了0.1（也就是頻率?。袁F(xiàn)在的時間是31.4（10π）了

有初中基礎(chǔ)的應該就能聽懂了...吧？

最后一個例子，相位Phase:

和上面那個圖片比較，你很容易就能看出哪里變了，如果沒有的話...

這張圖片給你：綠色的是原來的那張，紅色的是現(xiàn)在這個新的圖像

這下好懂了不？相位控制的是延時，也就是圖像的左右平移

如果我們想要讓視頻等半拍再開始搖晃，那么我們就可以選擇加入一個Phase的參數(shù)

通過以上三個最基礎(chǔ)的參數(shù)，我們可以快速地大致得到我們想要的效果

Z Dist Z軸距離偏移

默認是1.00，越大則視頻離屏幕越近，反之亦然

極端條件下可以用這個來做視頻分屏效果（？）

咳咳，實測效果還不錯就是了

Motion Blur 動態(tài)模糊

不需要解釋，動態(tài)模糊就是動態(tài)模糊，模擬人眼的

什么效果的話...你把你的手放到眼前，然后瘋狂撲哧，你看看你能不能看清你的手就知道了

打開這個就是那個感覺

Mo Blur Length 動態(tài)模糊長度

控制模糊量，輸多了小心變成油畫

Seed 隨機種子

隨機種子，在你的搖擺引入隨機相關(guān)參數(shù)的時候，如果對自己現(xiàn)在默認的搖擺不滿意，可以更改種子撞撞運氣

同時，同一個種子在不同設(shè)備上看起來的效果也是一樣

總是有可能能找到一個完美的預設(shè)的，對吧？

Wrap X X軸邊緣扭曲

????-No 無

????-Tile 平鋪

????-Reflect 反射

Wrap Y Y軸邊緣扭曲

????-No 無

????-Tile 平鋪

????-Reflect 反射

有的時候搖擺搖得狠了，可能我們的視頻會出界，右邊超界了左邊就會出現(xiàn)黑框，賊難受

這兩個功能可以幫我們掩蓋一下黑邊

選擇No就是保留一切黑邊啊啥的不管，運算量最少

平鋪和反射比較類似，在多的黑邊處放上視頻本身的邊角，只是一個是與視頻方向相同，另一個是相反，顧名思義

X Shake X軸震動

X Rand Amp 隨機X軸振幅范圍

X Rand Freq 隨機X軸頻率范圍

X Wave Amp X軸振幅波范圍

X Wave Freq X軸頻率波范圍

X Phase X軸相位偏移

OK，進階的來了：

振幅波的頻率單位為毫秒，即設(shè)定值為多少毫秒，多少毫秒就會震動一次

若一個曲子bpm為120，即每60秒有120拍，一拍就是500毫秒

此時若想拍拍相對，則Freq需設(shè)定為0.500

*注意：這邊設(shè)定的精度最高只能小數(shù)點后三位，即1毫秒整；碰到一些不整的情況最好分段來加效果，防止延遲堆積過大

例如bpm115，一拍是521.739ms，若想要2拍一對則需要設(shè)定為0.260(869565)，延遲會堆的很快

這塊不準備深入講，自己有需求的話，上手試一下就知道了

Y Shake Y軸震動

Y Rand Amp 隨機Y軸振幅范圍

Y Rand Freq 隨機Y軸頻率范圍

Y Wave Amp Y軸振幅波范圍

Y Wave Freq Y軸頻率波范圍

Y Phase Y軸相位偏移

與X相同，略過

X是左右搖，Y是上下?lián)u

Z Shake Z軸震動

Z Rand Amp 隨機Z軸振幅范圍

Z Rand Freq 隨機Z軸頻率范圍

Z Wave Amp Z軸振幅波范圍

Z Wave Freq Z軸頻率波范圍

Z Phase Z軸相位偏移

略過，Z就是前后搖（插件偽3D哦）

Tilt Shake 旋轉(zhuǎn)/傾斜震動

Tilt Rand Amp 隨機旋轉(zhuǎn)振幅

Tilt Rand Freq 隨機旋轉(zhuǎn)頻率

Tilt Wave Amp 旋轉(zhuǎn)振幅波范圍

Tilt Wave Freq 旋轉(zhuǎn)頻率波范圍?

Tilt Phase 旋轉(zhuǎn)相位偏移

略過，這就是旋轉(zhuǎn)

錨點貌似是跟隨視頻本身的錨點的，默認是視頻中間作為圓心

Channels 色彩通道

Red Amplitude 紅通振幅

Green Amplitude 綠通振幅

Blue Amplitude 藍通振幅

Red Phase 紅通相位

Green Phase 綠通相位

Blue Phase 藍通相位

RGB Randomness 色彩轉(zhuǎn)變隨機性

RGB Frequency 色彩轉(zhuǎn)變頻率

意外好用的一個小功能，效果基本等同于RGB Separation，就是色散效果

不過建議還是用別的插件做，這邊這個運算有點慢，好處就是這里一樣可以寫出規(guī)律的效果，畢竟都是三角函數(shù)啦

Opacity 透明度

-All opaque 通透

-Normal 直通

-As premult 預乘

直通alpha圖片保留最原本的RGB數(shù)值；而預乘alpha，是原本的RGB信息乘以alpha的數(shù)值以后得到的結(jié)果（預乘意思就是預先乘以alpha）

比較專業(yè)，建議自己上手去試試，這玩意屬于用了就理解，不用光講一沒人想聽二理解很難

Mask Use 使用遮罩

????-Luma 亮度通道

????-Alpha 透明度通道

高級用法，知道亮度和透明度遮罩的都不需要我教了

Blur Mask 模糊遮罩

同理

Invert Mask [Y/N] 遮罩反轉(zhuǎn)

略過，沒好說的

Crop Input 輸入圖像裁剪

????Crop Left 裁剪左側(cè)

????Crop Right 裁剪右側(cè)

????Crop Top 裁剪頂部

????Crop Bottom 裁剪底部

顧名思義，保留一塊安全區(qū)不進行搖擺

可以利用這個做出一些比較陰間的特效，但是總體感覺還是不如在一開始就給一個裁剪了

所有的參數(shù)以及用法差不多也就到這里了，因為是專欄，所以一切理解靠玄學了

畢竟也不是什么付費課程~要不是因為全網(wǎng)沒幾個我才不會寫這個專欄

s_shake是藍寶石插件中很具有代表性的一個，看起來就一種用法，但其實玩好了花活很多

把這個搞明白了，其他的也就不會有什么難度了

最后，附上藍寶石自己的用戶Manual內(nèi)對s_shake的介紹：

如果你把藍寶石裝到了默認位置，這個介紹應該能在這個地址找到

S_Shake

Applies a shaking motion to the source clip over time with translation, zooming, and/or rotation. The shaking is random but repeatable, so with the same parameters the same shaking motion is generated each time. Turn on Motion Blur and adjust the Mo Blur Length for different amounts of blur. Adjust the Amplitude and Frequency for different shaking speeds and amounts. The Rand parameters give detailed control of the random non-periodic shaking, and the Wave parameters adjust the regular periodic shaking. The X, Y, Z, and Tilt parameters control the horizontal, vertical, zoom, and rotation amounts of shaking respectively.

In the Sapphire Distort effects submenu.

Inputs:

• Source: ?The current layer.?? The clip to shake.

• Mask: ?Defaults to None.?? Interpolate between the result and the Source input. White areas use the result of the effect. Black areas use the Source clip.

????????

Parameters:

• Load Preset: ??Push-button.
  Brings up the Preset Browser to browse all available presets for this effect.

• Save Preset: ??Push-button.
  Brings up the Preset Save dialog to save a preset for this effect.

• Style: ??Popup menu, ?Default: Normal.
  Controls the type of shaking.
  

  • Normal: ?A steady camera shake.
    

  • Twitchy: ?Periods of stillness interrupted by bursts of rapid shaking.
    

  • Jumpy: ?Sudden jumps from one place to another, with slower drifting in between.
    

• Mocha Project: ??Default:?0, ?Range:?0 or greater.
  Brings up the Mocha window for tracking footage and generating masks.

• Blur Mocha: ??Default:?0, ?Range:?0 or greater.
  Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

• Mocha Opacity: ??Default:?1, ?Range:?0 to 1.
  Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

• Invert Mocha: ??Check-box, ?Default:?off.
  If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

• Resize Mocha: ??Default:?1, ?Range:?0 to 2.
  Scales the Mocha Mask. 1.0 is the original size.

• Resize Rel X: ??Default:?1, ?Range:?0 to 2.
  The relative horizontal size of the Mocha Mask.

• Resize Rel Y: ??Default:?1, ?Range:?0 to 2.
  The relative vertical size of the Mocha Mask.

• Shift Mocha: ??X & Y, ? Default:?[0 0], ?Range:?any.
  Offsets the position of the Mocha Mask.

• Bypass Mocha: ??Check-box, ?Default:?off.
  Ignore the Mocha Mask and apply the effect to the entire source clip.

• Show Mocha Only: ??Check-box, ?Default:?off.
  Bypass the effect and show the Mocha Mask itself.

• Combine Masks: ??Popup menu, ?Default: Union.
  Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
  

  • Union: ?Uses the area covered by both masks together.
    

  • Intersect: ?Uses the area that overlaps between the two masks.
    

  • Mocha Only: ?Ignore the Input Mask and only use the Mocha Mask.
    

• Amplitude: ??Default:?1, ?Range:?0 or greater.
  Scales the amplitude of the shaking motion.

• Frequency: ??Default:?8, ?Range:?0 or greater.
  Increase for faster shaking, decrease for slower shaking. (Be careful if you animate frequency values because the resulting shake frequency is also affected by the rate of change of the value.)

• Phase: ??Default:?0, ?Range:?any.
  Time shift of the shaking motions. (If you animate this value, its rate of change will also affect the apparent frequency.)

• Stillness: ??Default:?0.7, ?Range:?0 to 1.
  In Twitchy mode, adjusts the fraction of the time that the image is still. Increase for more frequent shaking.

• Twitch Frequency: ??Default:?2, ?Range:?0 or greater.
  In Twitchy mode, controls the length of the periods of movement and stillness. Increase for shorter, more frequent bursts of movement.

• Drift: ??Default:?0.3, ?Range:?0 to 1.
  In Jumpy mode, controls the speed of movement in between jumps.

• Center Bias: ??Default:?0, ?Range:?0 or greater.
  In Jumpy mode, adjusts the likelihood that each jump will reset the image to its original position. If set to zero, every jump is random. If set to one, every jump will go back to the center.

• Z Dist: ??Default:?1, ?Range:?0.001 or greater.
  Scales the 'distance' of the image. Values greater than 1.0 move it farther away and make it smaller. Values less than 1.0 move the image closer and enlarge it. Zooming in slightly can sometimes be used to hide edge artifacts.

• Motion Blur: ??Check-box, ?Default:?off.
  Options for motion blur of the shaking motion.

• Mo Blur Length: ??Default:?1, ?Range:?0 or greater.
  Scales the amount of motion blur. Use around .5 when processing on fields or 1.0 for frames to give realistic motion blur. This parameter has no effect if Motion Blur is?No.

• Seed: ??Default:?0, ?Range:?0 or greater.
  Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

• Wrap: ??X & Y, ?Popup menu, ?Default:?[Reflect Reflect].
  Determines the method for accessing outside the borders of the source image.
  

  • No: ?gives black beyond the borders.
    

  • Tile: ?repeats a copy of the image.
    

  • Reflect: ?repeats a mirrored copy. Edges are often less visible with this method.

  Amplitude of the rotational regular wave shaking, in degrees.

• Tilt Wave Freq: ??Default:?0.5, ?Range:?0 or greater.
  Frequency of the rotational regular wave shaking, in cycles per second.

• Tilt Phase: ??Default:?0, ?Range:?any.
  Time shift of the rotational shaking.

Channels Parameters:

• Red Amplitude: ??Default:?1, ?Range:?0 or greater.
  The relative amount of shaking in the red channel. Changing this value from the default will cause the red channel to move more or less than the other color channels, resulting in a color fringing or channel separation look.

• Green Amplitude: ??Default:?1, ?Range:?0 or greater.
  The relative amount of shaking in the green channel.

• Blue Amplitude: ??Default:?1, ?Range:?0 or greater.
  The relative amount of shaking in the blue channel.

• Red Phase: ??Default:?0, ?Range:?any.
  The relative phase of the red channel. Positive values will move the red channel ahead of the others in time, causing it to move first and the other channels to follow. Negative values have the opposite effect, causing the red channel to lag behind the others. Small values usually produce the best looks.

• Green Phase: ??Default:?0, ?Range:?any.
  The relative phase of the green channel.

• Blue Phase: ??Default:?0, ?Range:?any.
  The relative phase of the blue channel.

• RGB Randomness: ??Default:?0, ?Range:?0 or greater.
  The amount of random motion in each color channel. Turn up this parameter to cause all three color channels to move randomly on different paths, independent of the overall shaking. This motion is scaled by X Rand Amp, Y Rand Amp, Z Rand Amp, and Tilt Rand Amp.

• RGB Frequency: ??Default:?2, ?Range:?0 or greater.
  The frequency of the random color channel shaking.

Other Parameters:

• Opacity: ??Popup menu, ?Default: Normal.
  Determines the method used for dealing with opacity/transparency.
  

  • All Opaque: ?Use this option to render slightly faster when the input image is fully opaque with no transparency (alpha=1).
    

  • Normal: ?Process opacity normally.
    

  • As Premult: ?Process as if the image is already in premultiplied form (colors have been scaled by opacity). This option also renders slightly faster than Normal mode, but the results will also be in premultiplied form, which is sometimes less correct.
    

• Mask Use: ??Popup menu, ?Default: Luma.
  Determines how the Mask input channels are used to make a monochrome mask.
  

  • Luma: ?the luminance of the RGB channels is used.
    

  • Alpha: ?only the Alpha channel is used.
    

• Blur Mask: ??Default:?0.05, ?Range:?0 or greater.
  Blurs the Matte input by this amount before using. This can provide a smoother transition between the matted and unmatted areas. It has no effect unless the Matte input is provided.

• Invert Mask: ??Check-box, ?Default:?off.
  If on, inverts the Matte input so the effect is applied to areas where the Matte is black instead of white. This has no effect unless the Matte input is provided.

• Crop Input Parameters: ??Default:?0, ?Range:?0 or greater.
  These 4 parameters,?Crop Top,?Crop Bottom,?Crop Left,?and?Crop Right, allow selecting a rectangular subsection of the input image to be processed. If the Wrap parameters are set to "No" the exposed borders will be transparent. If the Wrap is "Tile" or "Reflect" the source image is wrapped on the new cropped borders to fill the frame. This can make it easier to avoid artifacts due to distorting an image with bad edges.
