Transparent bucket fill won't work - Holographic Breathing - 08-01-2025
For some reason, when I tried to make the background transparent, it doesn't work.
Here is a video of me trying and not succeeding.
It would be great if someone can tell me how to make this work.
Thank you for any advice in advance.

That looks like Gimp 3 to me - is it ? This next is much the same in Gimp 2.10
Some of your concepts are wrong.
Transparency comes from an alpha-channel. You add one from Layer -> Transparency -> Add Alpha Channel. If that is greyed out then the alpha channel already exists.
Removing a plain background can be done is several ways. For your image:
Colours -> Colour-to-Alpha The colour to remove is set as white, no need to change anything. If another colour then there is a colour picker to use. The colours in the image are light and they get a bit removed as well, become semi-transparent. Use the Opacity Threshold slider to restore. In Gimp 3 that is a layer effect (fx) so tick the merge option.

Saving / exporting. Save your work as a Gimp .xcf which keeps layers, transparency ... Exporting - Not all formats support transparency. Use .png or maybe tiff. A jpeg does not support transparency and replaces that with the current background colour.

Yes, it is Gimp 3
Thank you for your video.
that works well.
I don't understand why sometimes it works with the bucket fill and other times not
