之前有機會借到這張卡玩了2天,在AE中測試下列幾個特效都非常快:
1. Cartoon Effect 卡通效果
2. Bilateral Blur Effect 對稱模糊效果
3. Turbulent Noise Effect 可做火焰或水波紋效果,這個很強,沒有OpenGL支援會算粉久
同時它可以支援OpenGL對nested comps加速算圖,這個也是很棒,如果你只有幾個臨時演員卻要作千軍萬馬的效果時,通常會用nested comp,這時加速RAM Preview就很好用了。
另外,根據使用手冊的說法,OpenGL在 After Effects 可以做下列算圖功能:
* Shadows, except point light shadows (Colored shadows appear gray.)
* Lights (eight maximum)
* Masks
* Alpha channels
* Track mattes
* Intersecting layers
* Transformations for 2D and 3D layers
* GPU-accelerated effects, including Alpha Levels, Bevel Alpha, Bilateral Blur, Box Blur, Brightness & Contrast, Channel Blur, Color Balance, Color Balance (HLS), Curves, Directional Blur, Drop Shadow, Fast Blur, Find Edges, Fractal Noise, Gaussian Blur, Hue/Saturation, Invert, Noise, Radial Blur, Ramp, Sharpen, Tint, and Turbulent Noise
* All blending modes except Dissolve and Dancing Dissolve
* Metal property settings for 3D layers
* Cone feather settings for light layers
* 2D motion blur
* Adjustment layers
* Anti-aliasing
* Depth-of-field blur
* Nested compositions
也就是說,這些都可以透過支援OpenGL的顯示卡加速
Quadra CX卡的Cuda可以用在Premiere CS4的算圖上,這段影片 http://tv.adobe.com/#vi+f1510v1002 可以看出只要一半時間就算完了。
不過這張卡不便宜,USD$1999,以規格及價格看,應該是Production等級的人會需要 :-) |
