No it isn't, 100% of the heavy lifting is via gstreamer, which is all written in C. Python is a wonderful language, especially with gtk, for writing user interfaces. The real magic of pitivi is in gnonlin[1], the horribly named project which is a library for building video editors (essentially). Disclaimer: www.pitivi.org + their wiki runs on my linux server and I help the project from time to time. [1] http://gnonlin.sourceforge.net/ http://gnonlin.sourceforge.net/
