If you're just looking for conversion, you might want to try arista or transmageddon instead of Openshot. Arista Transcoder and Transmageddon are applications focused on just doing the conversion and nothing else. Especially Arista Transcoder contains a lot of presets, of which one is xvid. Install them using the command sudo apt-get install arista transmageddon.

Gman

From the Ubuntu man page, Gman is a "GTK+ based front-end for man, a good replacement for xman."

Gman provides an index of the man pages installed on your local system and offers several options for viewing the man pages. The default option is to have gman open the man pages within an xterm session. This can be modified to suit your taste with four other options.

The other viewing options available are:

• ghostview
• Evince
• LocalBrowse
• NetBrowse

In order to change the application used for viewing, select View from the menu and then select the radio button next to your preferred application, as shown below:

The last two options require having the man2html package installed on your system and will bring up the man pages in your default browser.
