Boris Continuum Complete is a special effects plug-in package that works in conjunction with Adobe Creative Suite, including CS6, Avid editing and finishing systems such as Sony Vegas Pro, and Apple Final Cut Pro.
YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.
Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. Today, most compositing is achieved through digital image manipulation. Pre- digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century, and some are still in use.
A common ability is to do compositing techniques such as chroma keying or luma keying, among others, which allow different objects to look as if they are in the same scene. [3] A different kind of visual effects is motion capture. Software such as Blender can perform motion capture to make animated objects follow an actor's movements.
Luma is the weighted sum of gamma-compressed R′G′B′ components of a color video—the prime symbols ′ denote gamma compression. The word was proposed to prevent confusion between luma as implemented in video engineering and relative luminance as used in color science (i.e. as defined by CIE ).
luma is the encoded video brightness signal, i.e., similar to the signal voltage V S. One contrasts relative luminance in the sense of color (no gamma compression) with luma in the sense of video (with gamma compression), and denote relative luminance by Y and luma by Y′, the prime symbol (′) denoting gamma compression.

Many non-Adobe commercial graphics applications also support Photoshop-compatible plugins – Paint Shop Pro, [4] PhotoImpact, and Corel PhotoPaint are some of the better-known ones. There are several dozen more plugin hosts, including lesser-known products like Chasys Draw IES, the free-software image editor GIMP, and viewers like IrfanView. [5]
The Photoshop and illusions.hu flavors also produce the same result when the top layer is pure white (the differences between these two are in how one interpolates between these 3 results). These three results coincide with gamma correction of the bottom layer with γ=2 (for top black), unchanged bottom layer (or, what is the same, γ=1; for ...
