You can use an animation as
the
swap buffer in the Timeline, with filters that use the Swap buffer's
image for such things as combining or displacing. This can create
very cool effects, like this swimming distortion by using a perlin
noise animation with a displacement filter. This one was done quick and
dirty, with not much attention to detail. You can of course reduce the
intensity of the displacement.
This looping animation of a 39-frame wave displacement was
created to serve as a basis for the animation to run in the Swap
buffer. It will displace another animation.
For example,
an image with some text was replicated 39 times to have the same frame
count as the wavelet animation. The wavelets then can be used with the
'Displace by Swap' filters.
Or you could
use the cloaking displacement with varying parametrers set by keyframes
along the timeline
Displacement
is not the only thing possible. There is a large list of 'Combine with
Swap' filters, with modes like Additive, Subtract, Multiply, Xor,
Screen and many more.
Snowfall up and
down
Or here's
another example, with an animation created with the Snowfall
filter used twice and a vertical flip in-between and change in
brightness, so some snowflakes move up and others move down, causing
different displacements when used as animated Swap with the
displacement filter.
Some of the
'Combine by Swap' filters can generate interesting color explorations
Fast Rising Bubbles
Another
Looping animation. This one shows bubbles rising fast. (created with
the snowfall filter, and making it loopable)
This one used the bubbles as displacement.
This one used
the same bubbles in one of the 'Combine with Swap' filters.
Here
are a bunch more, using additional filters for further effects, such as
embossing, light diffusion, spherical distortion,...
