Inverting the warp stabilizer?
by Clay Hammons on May 8, 2012 at 2:13:12 am
I am working on a handheld shot and am hoping to find a way to use the warp stabilizer to remove motion from the shot, add my effects to the background then undo the stabilization so its back to being handheld so that the effects will then use the inverted stabilization data. If its possible could someone give me a general workflow of how to do it? If its not possible with the warp stabilizer what would be a workflow for doing it with the legacy stabilizer?

The SynthEyes image preprocessor and stabilizer are invertible, so this workflow is pretty straightforward. You should pad up the image in the preprocessor before stabilizing, so that you don't have to have any part of it get cropped, since you want the full original image back. You should specify a higher output resolution, so that the padding area doesn't cause any downsampling.
After you output the stabilized sequence and add your effects, you take the same scene in SynthEyes, and do a Shot/Change Shot Images to your modified footage. That will give you an option to select for re-distorting CGI effects; it will reconfigure the image preprocessor to remove the upsample, stabilization, and padding --- giving you back images that match your original.
