Stabilizing Footage
Hi All
I hope someone out there can help me with this. I’m attempting to Rotoscope a subject in AE using a similar approach that many rotoscope artists would use in Silhouette or Nuke. To aid the overall roto process I want to cancel out any camera movement by stabilising the footage, then rotoscope my subject, e.g. head, torso, arms, legs, etc using Rotobezier shapes, then finally destabilise the plate so the rotoshapes follow the subject using the original camera move.
Can anyone tell me if this is possible or if there are any tutorials out there that would enable me to use this workflow AE? I’ve searched everywhere I can think but only find artists using the stabilize as a correction tool for unwanted camera shake.thanks so much for any help with this.

Don’t use Warp Stabilizer. Use the Point Tracking stabilizer. The workflow might look like:
Stabilization Comp – use the Point Tracker and apply the track to the footage as stabilization.
Roto Comp – Bring the Stabilization Comp as a precomp into this one, and do your roto on the stabilized footage.
From here, you could do one of two things: Precompose the Roto Comp into a Final Comp. You’d then use the Point Track keyframes from the Stabilization Comp to restore the motion of the roto-ed footage from the Roto Comp.
Alternately, you would create an entirely new comp, and paste in the footage and track points from the stabilization comp. Then bring in the masking keyframes to a matte layer, from the Roto comp, and apply the Point Track keyframes to the matte so that instead of the footage being stabilized by the tracking data, the tracking data adds position/rotation to the matte.
Someone will probably have a more elegant solution, but these are the first ones that come to mind for me.
