I'm having trouble using the Apply LUT filter/effect in Kdenlive 20.04.1 in Windows.

When I select a clip and then select the Apply LUT effect I get the small error dialogue box that says: [filter avfilter.lut3d ] Cannot init scale filter: Invalid argument

This is the first time I've had an issue applying a LUT as usually this effect works without any problems.

Dear Brett,

I just ran into the very same issue just now. Using kdenlive beta 20.11.80 on Tumbleweed.
I hoped somebody would have thought out a solution already, but seems like not.

Greetings & good luck!

Even though you get an error message it works, just select the LUT and it will work...
