I’ m almost sure you know G’MIC, a well known plug-in to GIMP, if not called “THE plugin” if any else, in the GIMP community (it works as a stand alone as well).
if you could add it to Shotcut, that would be a huge feature and effects increase. It has a compatible license as G’MIC is CeCill.
I quote:
G’MIC is an open-source software distributed under the CeCILL free software licenses (LGPL-like and/or GPL-compatible).
Natron, a FLOSS video compositing VFX software, added the possibility to plug G’MIC a decade ago, nowadays Natron send itself with G’MIC already included.
Just a suggestion
Any question, do not hesitate, I’ll be happy to answer.
In all case Shotcut is already pure awesomeness as it is!
Thanks for reading.
Something like this and other user-installable plugins requires a UI generator, which is something Shotcut lacks. We opted to first make a way to manually create custom UIs quickly, which are also translatable, unlike a lot of generated UIs. This will likely only come after the MLT engine includes support for OpenFX plugins, which is in progress. The Shotcut road map has “generic filter UI” on the road map.
