854 Chapter 27 Warping and Morphing Images
You can also individually animate the displacement caused by each source/target
shape pair you’ve defined. To do so, open the connectionName subtree to reveal the
connectionDisplacement parameter. Animating specific parameters can create a more
organic-looking effect.
Using the Morpher Node
The Morpher node blends two images together to create the effect of one subject
changing shape to turn into another. The Morpher node does this by performing two
warping operations, one on the source image to warp it into the shape of the target
image, and another warping operation to warp the target image from the shape of the
source back to its own shape. Once both warping operations match the shapes of the
source and target images to one another, a built-in cross-fade dissolves from the first
warp to the second, providing the illusion that the first image is changing into the
second.
Tips For Successful Morphing
Successful morphs benefit from planning ahead during the shoot. Ideally, the positions
of the source and target images match relatively well. If they need adjustment, resizing,
or repositioning to help them match better, you can make these adjustments in your
node tree prior to adding the Morpher node.
If the source and target subjects are moving, their movements should match one
another so that the warping targets you set for both can line up properly. If the
motions line up but the timing is off, you can select the offending clip’s FileIn node and
use the Timing tab parameters to remap its speed so that the motion lines up. For
more information, see “
Retiming ” on page 117.
