I was excited to stumble across some LUT effects in Kdenlive today (under 'Misc'). There is LUT, LUT3D LUTRGB and LUTYUV. It's not immediately apparent to me how these work though, as they don't appear to have any accessible controls. I have searched in the handbook and Wiki but not come up with any information, is there anything out there at all about using these? Specifically can you load a .cube file into them?
Thanks in advance!

Interesting update over on the Shotcut website regarding this:
https://shotcut.org/blog/
The relevant passage being:
"Another forum user suggested to add a 3D LUT filter. Fortunately, this was already available through the MLT+FFmpeg engine, and it was easy to add a UI to expose this powerful filter."
Does this mean it might be relatively straight forward to add this to Kdenlive as well?

This is indeed rather straightforward.
I'm working on it, and without unexpected roadblocks, it should be available soon. Stay tuned

Excellent news! Thank you for your efforts.

Patch merged into the codebase It should be shipped into the next release. Enjoy!

Hey, thanks a lot for the patch! So nice to see more people joining in! Besides the forum (here) and mailing list, we have a community at G+ (if you use it).

PS
I am working on tagging "low hanging fruit" section in the tracker, if you'd like I can point you to some easy bugs

Cheers and thanks!
