RE:Flex是很有意思的变形AE插件，可以让演员表情更加丰富！还可以做人物过场变形动画，还有从小孩慢慢变老的过程，下方有效果视频。
REVisionFX RE:Flex brings intuitive morphing and warping to combustion, After Effects, Shake, Autodesk Systems (IFFFS) and Fusion! Superior results are achieved using RE:Vision Effects’ proprietary and sophisticated technology. RE:Flex is especially easy to learn because it uses the host program’s own drawing and masking tools (when available) to direct the warping and morphing; as such, there is no need to learn a whole new user interface. Using our proprietary tracking software, RE:Flex is the first morphing program to combine hand feature-matching with automatic image registration.
With RE:Flex warps are made easy. Just specify “from” geometry (in red) and “to” geometry (in yellow). No meshes. No new user interface to learn. Masks can be open or closed and need not be connected in any particular way. Picture courtesy of Videometry.
RE:Flex’s automatic alignment feature works in conjunction with hand-specified correspondences. After first aligning hand-matched correspondences, RE:Flex then uses the tracking found in RE:Vision’s acclaimed Twixtor product to automatically align the non-handmatched parts of the image. The automatic alignment feature can greatly improve morphs without having to specify all features by hand!
新特性：
– Warping is directed through the host program’s roto tools (splines and polylines), not through a grid of mesh points!
– Geometries need not be closed shapes
– Smooth non-polygonal warping
– Interactive warping: view the warp as you drag the control shapes
– Option to match vertices of corresponding geometries for fine control
– 8 and 16 bits per channel support. Floating point supported in AE 70 or later (Professional Edition), Shake and Fusion.
– Anti-aliasing subsampling
– MipMap filtering
RE:Flex Warping Features
– Warping is directed using sets of “from” geometries and “to” geometries at each frame.
– The amount of warping can be specified and animated.
– Variable amount of shape transition between “from” and “to” geometries can be specified per-shape.
RE:Flex Morphing Features
– When morphing from stil-to-still morphing occurs by creating a set of geometry on the “source” image, then moving the set to corresponding places on the “destination” image.
– Automatic alignment feature that can be used alone or in conjunction with hand-specified correspondences. This feature can greatly improve morphs without having to specify all features by hand.
– Morph from one moving sequence to another.
– By default, the two images are linearly cross-dissolved. For finer control, the amount of cross-dissolve can be specified for each piece of matching geometries individually.
– Variable amount of shape transition between “from” and “to” geometries can be specified per-shape.
