I simply exported my pre-composited footage from Olive and the first 3/4 of
the video I've managed to edit and completed the project in Kdenlive.
I had some bad audio glitches from Kdenlive though, so I wasn't happy :(
I think Olive is going to implement Open Timeline IO too, but I don't know
what the status of that is.
