I have bought VisionLab a few weeks ago and I am quite happy with what I can achieve with it. However, going more and more into depth and want to do some advanced effects and wonder if VisionLab can do this somehow:
1. Roto Brush:
From the latest After Effects adds I am quite impressed with the new "roto brush" feature. Its basically a mask that automatically outlines and tracks a moving foreground element in your footage. For example, you can just click on an actor in your footage once. Then After Effects not only auto-generates the mask around this actor, but does this for all frames of the footage.

This is obviously quite cool. Doing the free hand mask is not as efficient for complex shapes against complex backgrounds where using a green screen was not possible or done for whatever reason. And even worse, manually animating the VisionLab freehand masks frame by frame is as time consuming as it is prone to "jumps" from frame to frame.
So the question is: Is there any way in VisionLab to auto generate a free-shape mask by edge detection in the video footage? Or does anybody know if FX Home plans to add such a feature in future version. I feel this is a key feature one cannot live without today
Smoothin blending footage against mattes
I am thinking of having some footage in a nature environment. In this footage I would like to blend the original footage on the left and right side into a digital matte. The following image goes some steps ahead of this but I found no better sample of what I mean. Its from "Pirates of the Caribbean 2" where they blended the original footage of a bridge into a digital matte with more exciting background.

I know how to blend in a matte onto a footage using a VisionLab mask and transparency. However, what I'm looking for is a changing transparency value not over time but across the mask itself. Say on the left hand side of a mask I have full transparency and on the right hand side of the mask I have full opacity. Even better would be a circular (or arbitrary shape) on a rectangular mask that defines the fully transparent area from who's edges the transparency is then interpolated down to 0 at the rectangles edges.
Anyway, is there a way in VisionLab to achieve this smooth blending into a background image across a mask?
Thanks for reading (and hopefully answering) this post
