Bubbling Video cauldron effect
Hello!
I would like to make an effect in after effects that automatically spawns clouds or bubbles containing time offset reflections of the video playing in the background such that the clouds or bubbles float toward the viewer
For example if someone is speaking in a video clip, clouds or bubbles containing time offset versions of the same clip would float up toward the camera expanding indicating in perspective that they are getting closer, but you would see an overlapping random jumble of the moments that just past, like moving images of moments just past rising toward you in steam clouds
What are some good ways to go about achieving this? Are there any particle systems that make something like this easy such as any of the red giant trapcode stuff?
