With this function you can convert the points tracked with kdenlive functions Motion-tracker or Auto-mask and generate the inverted movement, this way you can use the new points to stabilize the tracked point instead of following it. Yeah... I need to explain this another way...

Better than that, check out this Ferrolho's blog entry and notice how this function was 97.12% inspired by his work. While in there also notice how less lazy he is at explaining how to use the function. Amazing!!

This will create some fake hand shake movement

Ideas are welcome. You can post it here.
