Hello. I'm new here, so I apologize if I posted in the wrong area or did anything incorrectly.

I downloaded Kdenlive today on Windows 10, and when I try to use the CMYK adjust (avfilter) effect on my videos, the values don't load in. I just see what appears to be a loading bar move across the screen: https://i.imgur.com/JIcb43O.jpg

This is what it's apparently supposed to look like: https://i.imgur.com/uYahR13.jpg

Additionally, in the first image, I have these effects labeled B, G, and R which only turn my image black-and-white. I might be wrong, but I feel like those should not be like that.

I've tried reinstalling and restarting, and I've looked through the Known Issues page but found no solutions. I tried Googling, but it seems like no one else has this issue. Does anyone know how to fix this or should I just submit a bug report? Thank you for your time.

Please try with Kdenlive 20.04. Some effects are fixed there.

Same problem for me on linux:
