Operations with masks and image stacks - selective video stabilization

[Abrimaal]

I am trying to stabilize short video sequences to the moving object.
Trying to stabilize video this way, that the moving object is always in the middle of the video - it can be a human, a car, anything in distance.

This method ignores the background by exclude masks and/or finds control points only in the moving object using include masks.

The image stacks are video frames.

I experiment with masking, removing control points in masks or outside masks, then removing masks.

Other tests exclude all moving objects, to stabilize video to the background.
Even if the moving objects are close, they are masked out.

I have found in Hugin menu only "remove all control points in masks" - it is very usable,

but I am not sure if it removes points in include masks too?

It takes long hours to work with masks even with 100 frames.

Are there any batch operations on masks available?

I am looking how to make the work simpler, it means:

- add the same mask to all images (to ignore logo or other overlay)
- delete all masks from all images
- toggle all masks from exclude to include and vice versa
- inverse all masks (what was masked becomes unmasked)
- find control points only in include masks

Are the features available in the Advanced mode
or by modifying .pto files in a text editor (Notepad++)?
