Hi Guillermo,
I tried the method in your tutorial on the images I sent you. 

This is the result I got.  Not sure if I did it right so I included the layer tab in the screenshot which shows my settings.  The white is all blurred overlap including the edge of thinner branches moving with the birds weight.  Perhaps expected?

Interested to see if your version looks the same.  The birds in flight came out looking good where there was no overlap (2 small grey spots).

Hi Dave, sorry for the delay, busy week. Yes, your result is correct. Unfortunately it seems when the difference blend mode in PS yields negative values they are inverted and that is why the white colours in the areas with static birds. It was nice to try though, right?

I have just expanded a bit the fusion map in the RAW version of the antimedian from a 9px mode to 21px mode, and the RAW data in the runner sequence becomes nearly perfect even in overlapping areas:





The final RAW file:
