Warping Multiple Reference Frames

Some sequences involve movement and detail that can't be propagated from a single frame correction. In these cases, you can use multiple VectorDistort nodes with different reference frames to minimize the amount of correction work needed.

1.   Set up your first paint correction as described in Adding Paint to the Source and Applying Motion Vectors to the Source.
2.   In the VectorDistort node's properties, disable the Hold Frame control.
3.   Add a FrameHold node before the RotoPaint node containing your corrections.
4.   Set the first frame control to the reference frame specified in the VectorDistort node.
5.   Set the lifetime of your paint strokes in the RotoPaint node Lifetime tab to the same frame range as the VectorDistort node.

6.   Repeat the process for the required number of reference frames to complete your corrections. An example node tree might appear as follows:
