Eraserhead (Composition by gtoledo3)
This is a composition that uses sample and hold, with blend with mask mode, to create an effect that lets you "erase" between a snapshot from the video cam, and the current feed. Another image source could be used in lieu of the sample and hold video shot. Tweak the interpolation duration to change the snapshot delay. The initial idea, for me, was to take a snapshot while out of the view of the cam, walk into the cam feed, and then "erase" over parts of my body! An older composition... |
Cool. Thanks, George! On my computer the image freezes if the eraser size is adjusted while the composition is running. Stopping and restarting the composition eliminates the freeze.
I took this plus some opencv optical flow (also ripped from a composition by gtoledo3) and made a composition which should be a race between two video feeds to erase eachother. Unfortunately I only have an old powerbook g4 which does not like two cameras at once so I am not completely sure if it is working. On the off chance that it is, I posted it. At the very least it may be another jumping off point for someone.
