How's this for an idea?
Take video, track with boujou or similar, bring into a 3d app, delete all the camera's tracking except rotation.
Have a script that creates rectangular sections, centered on the camera and occupynig its field of view. One for each frame of the original video. As each frame is projected move the others down fractionally so the most recent frame is on top. Remove completely occluded frames.
The point would be; rather than stabilising in something like afterfx, which effectively reduces the frame, this would increase it, giving a larger buffer the more the movement of the camera.
Of course it wouldn't work with all footage, you'd get artifacts if you were relying on frames that were too old and out of position, but it would mean, especially in tripod mounted shots, that you could 'paint' a buffer around your action and then rerender through a 3d animatable camera.
Anyone want to take a crack at it? My scripting skills are zero.
Or, if something like this already exists, where could I find it?
