Transparent Background Problem - Purplechris83 - 08-18-2020

Hi guys,

I'm new to this. I've been using the following method to cut a product out of a picture and make the background transparent:

Add Alpha Channel
Select Product image i want to keep using Free Select
Feather Image by 5,000 px
Invert
Clear

and this method has been working great until today where I have carried out the above method but when I put 5,000 px in Feather it won't accept it and keeps changing it to "50.00" px and then when I Invert and go to clear it makes the image a little transparent but I can still see the background. I have to keep pressing Clear 10 times until the image background is completely gone and then export but the image quality suffers and I'm wondering what I am doing wrong?

To try and fix this I have reinstalled GIMP twice (to a different directory the second time) and gone to Edit -> Preferences and Reset everything but I'm still having the same problem.

HELP! And thanks in advance.

When you say "5,000" do you mean five or five thousands? If Gimp is set up for some default English, it is likely awaiting a dot (5.000) or nothing (5) if you meant 5 pixels.
