This is now the preferred way to install OpenShot for Ubuntu 9.10 and above. If you use an older version of Ubuntu, you will still have to use our .DEB installers. Also, I highly recommend un-installing any existing version of OpenShot (and it's dependencies) before you install via the PPA.
Using this PPA is simple! Just enter the following commands, and that's it.
Now that OpenShot is installed, you should be able to launch it from your Applications > Sound & Video menu, or from the terminal ($ openshot). Every time we update OpenShot, you will now be prompted to update to the newest version. It's a great way to test our latest features.
