OpenCV Freeframes and v4. (trautner and countour)

Hey everyone

I’m Luka and i’m new to v4.
I was trying to follow a tutorial that creates some kind of motion tracker.
But there were 2 component called trautner and countour that i don’t have.
Can someone explain to me how to install them?

Thank you :)

hei luka, you’re most likely using a 64bit build which is missing some nodes for technical reasons. so if you need those please resort to the 32bit build.

Thanks joreg this helped
