I had to crop an image out of your video for tests. It is smaller than the original, results might not be exact.

i suppose the bimp bucket with so many possibilities...

Using the bucket-fill With BIMP is not possible. The bucket-fill tool creates a selection for the fill, BIMP does not support selections. The bucket-fill in BIMP fills the whole image.

could make the same result?

Most alternatives scripts / plugins use a selection, with the above BIMP restriction. It might be possible using the gimp_gmic_qt plugin, http://www.gmic.eu, which has a select-replace filter.

The only way I can think of to remove the shadow at the bottom is mask it out with a blank white image.

See if you can follow this procedure: https://youtu.be/ZoxAr4l2koc 3 minutes duration Remember I only have the single image to work with.

---------------
I mentioned a command line alternative ImageMagick http://www.imagemagick.org and that might go like this

To fill the background

Code:

magick image-in.png -fill white -fuzz 80% +opaque "#000000" temporary.png

To mask out the bottom shadow

Code:

magick composite -gravity south  blank.png temporary.png  image-out.png

You need to wrap that up in a batch file depending on operating system
