Description

PHYX:matte is a collection of PPTs (PhyxProcessingTrees) designed to create and manipulate matteswithin Apple Shake. PHYX:matte IS included in the 'PPTbundle'. The eight plugins included with MATTE are: Despill, DifferenceKeyer, EdgeBlend, EdgeBlur, EdgeMelt, Lightwrap, LumaKeyer, and PhyxKeyer.

List of Effects

Despill Despill processes images to remove excess green or blue (spill) from the edges of objects photographed in front of a green or blue screen. This processor works efficiently to ‘neutralize’ the excess green or blue. Despill generally follows a keyer node, such as the Phyx Keyer-- and may be applied before a layer node (such as an Over node). We believe that you will find the Despill to be the ultimate despill processor on the market today in terms of ease-of-use, despill quality, and processing speed.

DifferenceKeyer Difference Keyer creates a map of the difference between two images. Difference Keyer is used most often when a scene is photographed without foreground elements (called a ‘Clean Plate’), and is photographed again with the foreground elements (actors, etc.) in place. The Difference Keyer may be used to compare these images and output a ‘map of the difference between the images-- which may be used as a matte. This matte may be used to feed the matte input in a KeyMix node, or most other nodes in Shake.

EdgeBlend Edge blend is essentially a subtle edge-blur, but is quite different than most other ‘edge-blurs’, which simply blur the alpha. Edge Blend intelligently blurs the RGB of the image based on the outer-edge of the alpha channel. This produces a subtle blending effec. Edge Blend does not cause the alpha to ‘halo’ like blurring the alpha channel will do. Edge Blend is slow in-use, as it uses a very accurate edge-detection algorithm. Edge Blend may be used after a Layer node, such as ‘Over’. When used in this manner, it will blend/blur the edges of the foreground and background together, creating a smoother edge.

EdgeBlur Edge Blur subtly erodes the edges of the alpha as it is blurred. This effectively cancels the "edge grow" syndrome caused by simply blurring the alpha channel, and can create much smoother (and realistic) results. Edge Blur may be used along with Edge Blend for seamless edges.

EdgeMelt Edge Melt has only one control-- "MatteShrink", which controls the amount of melting/shrinkage. This processor is used for much *less subtle* edge blurring/shrinking than edge blur. Edge Melt is essentially the nuclear version of Edge Blur, and should only be used when extreme edge melting is needed.

Lightwrap Lightwrap finds the edges of a keyed element’s alpha channel, and ‘wraps the light’ of the background around its edges. Light Wrap can be very useful for blending foreground elements in composites. The second input is for the background, or ‘light source’. Light Wrap should be used *before* a layer node (such as ‘Over’). Typically, for a green or blue screen key, the flow is: FileIn, Keyer, Despill, LightWrap, Over.

LumaKey Luma Key is an extensive Luma keyer for Shake, which adds several controls beyond the luma keyer included with Shake. Luma Key is designed to key only the darkest or lightest regions in an image. Luma Key includes controls to determine if lightest or darkest shade within the image are keyed. Luma Key also provides control over contrast, gamma, and amount.

PhyxKeyer Phyx Keyer is a color difference keying solution for Shake. Phyx Keyer mathemagically analyzes the RGB values in a blue screen or green screen shot, and creates a map of the difference between the keyed channel (blue or green), and the other channels. This ‘map’ may be used as a matte. Phyx Keyer includes controls for selecting blur or green, an invert control (to invert the matte), plus gamma and scaling for control of the matte. Phyx Keyer may compliment our free 3d Keyer. Neither keyer is best for everything-- they both are equally useful in different applications. Phyx Keyer and our 3d Keyer may be used together for certain situations. In this case, each keyer may be followed by a Reorder node to reassign the alpha channels to RGB channels. These mattes may be combined with Min, Max, or other nodes, for best results.
