Though I do find the choice of using Cinelerra to edit the video a bit odd. Apparently there was an update to the project less than a year ago but I have personally never even been able to even import a video without it crashing.
Using something like OpenShot, KDenLive or PiTiVi or even Blender only makes sense to me.
But Cinelerra obviously worked out for them; the productions are absolutely spectacular. Loved every bit of this one. The clearest explanation one could hope to get.
The sad truth is that all the open source video editors are like that depending on what you're doing (with the possible exception of OpenShot, which I found to be reliable but limited).
In short, I found no FOSS video editor that did what I needed reliably out of the box. Given that problem, Cinelerra at least came close, the code was readable, and the design sound. Its biggest problem is that its file loaders/exporters are all old and bitrotting so they have become unreliable and crash-prone. For my stuff, I use raw video and so don't hit those problems.
In the process of making Episode 2, I wrote a new compositor resampler and a new color grading filter for Cinelerra (named Blue Banana). These should be appearing officially in the next major release. I hope to have some more file loader work done by then too :-)
