How do I install Cinelerra 4.4?

OK, first of all, Cinelerra has 2 versions:

  1. Comunity maintained version called cinelerra-cv which the last update was in November 13, 2011 and in the Git repositories 24 Sep 2012. Quite old.
  2. Heroine Virtual LTD maintained, which from now I will call cinelerra-hw. Last updated July 9, 2012. Still old.

Ubuntu repositories includes cinelerra-cv package in the repositories while cinelerra-hw seems no were to be found. Or so it seems. In the launchpad page of cinelerra-cv there is a note that reads:

Experimental builds of Cinelerra based on the upstream Heroine Warrior release (4.4) are available here:

https://launchpad.net/~cinelerra-ppa/+archive/cinelerra-hw

So, we only need to sudo add-apt-repository ppa:cinelerra-ppa/cinelerra-hw and ready. Please note: This ppa provides EXPERIMENTAL and therefore untested builds for the upstream release of audio and video editor Cinelerra (v. 4.4). Any problems with the installation and use goes for your own accord. If you need stability use cinelerra-cv or use the fork lumiera.
