Hello Everyone!
I recently watched Revolution OS and have become a huge fan of the Linux movement. I am running Ubuntu 13.10 (Saucy Salamnder).
I tried installing Cinelerra and have read the past thread for installing it and still can't figure it out. When I type the command "sudo apt-get install cinelerra" this comes up:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package cinelerra is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'cinelerra' has no installation candidate

I have past video editing experience using Adobe CS4 Premier Pro. I installed kdenlive but I am looking for a video editor that will enable me to edit clips from an external drive without ever loading them on to internal drives in my cpu. To edit clips in kdenlive they have to be on my main internal drive. I am hoping like Adobe CS4 Premier Pro Cinelerra will let me do this.

Any advice or suggestions?

With Peace and Thanks,
Newzzini
