I decided to throw in the towel on this for now.
I read another thread about how Pitivi 0.92 is an Alpha version. This thread
also mentioned that Pitivi 1 will eventually be packaged for the
repositories. I'm more in the user arena, and it seems the Alpha version is
out of my reach. It also appears best if I wait for the more stable version 1
to get involved.
I should be able to get by with the prior version of Pitivi, Kdenlive and -
possibly - Blender for now. I will be comparing and contrasting these to my
old (un-free) editing software.
Regardless, thank you all for the feedback!
I'm nearly set with my core applications, and it's time to began the gradual
transition!
