HandBrake is a program for transcoding video files. By default it transcodes video to H.264 format, so the files get compressed to a reasonable size while retaining high audio and video quality. There are versions available for Windows, OSX, and Linux. In this post I'm going to show how to install it in Linux Mint 13 using an Ubuntu PPA (Personal Package Archive).
Add the HandBrake PPA to your software sources
Use the following command to modify your software sources to include HandBrake.
Enter your password if prompted to do so.
The terminal will then display a message with a little bit of information about Handbrake. Hit <ENTER> to continue. The PPA will now be added to your apt sources and the package signing key will be added to your trusted list.
Now that the HandBrake PPA is added to your sources list, you need to update your package database.
With your package database updated, you can now install HandBrake.
You should now be able to find HandBrake in the Linux Mint menu (both MATE and Cinnamon editions) under Sound & Video -> HandBrake.
