How to Install Avidemux in Ubuntu:

For Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, you can install the new Avidemux packages via the unofficial PPA.

Sorry that the package names are still avidemux2.6 due to lack of time and my poor language skill.

1. To add the PPA, open terminal either via Ctrl+Alt+T or by searching for ‘terminal’ from app launcher. When it opens, run command:

sudo add-apt-repository ppa:ubuntuhandbook1/avidemux

Input your password (no visual feedback while typing) when it prompts and hit Enter.

2. Then install avidemux2.7-qt5 package either via Synaptic Package Manager or by running commands:

sudo apt-get update

sudo apt-get install avidemux2.7-qt5 avidemux2.7-plugins-qt5


For any reason remove the software via command:

sudo apt-get remove --autoremove avidemux2.7-qt5 avidemux2.7-plugins-qt5

To remove the PPA, launch ‘Software & Updates’ utility and navigate to ‘Other Software’ tab.

    Hey Jim Thanks for your effort to compile and upload some recent and popular Apps version to your PPA ;)
    I hope you will keep targeting Ubuntu compilations to 16.04.

    Thank you for avidemuxa, but how is it that the title is 2.7.1 and in the command apt-get install avidemux2.6-qt?

  3. Great job! This allows me to strip 4K footages on a very humble mini-pc (vivomini un45 with Celeron N3000).

  4. I get an error: Muxer cannot open. Any ideas?
