Thanks for your tests, Here is some feedback:

We should be able to easily restrict input to positive values

Freezes image for me, but seems useless.

Yes, it will  need some more work on the kdenlive side to be usable

Correct

Seems to me like it only crashes on negative values, we could easily restrict 
the parameter values to positive only...

I don't have that one

Same for me

That's normal, it extracts the Red, Green or Blue channels

Yes, seems broken

It would be interesting to see if we can find a valid range which does not 
crash, then restrict the input to these values

Seems to work for me... it keeps the colors close to the selected one, all 
others go black & white

Not really implemented

What do you mean ?

Same for me

Yes, removing not completely implemented effects seems a good idea to me. I 
will have a closer look later.
