Linux Alternatives to Popular Windows Applications / Package Finders

Recently I have been trying to edit a video in Linux and haven't quite found a good editor comparable to some editors I use in Windows. I found a few sites that were very useful to me and may be helpful to you.

The Linux Alternative Project
http://www.linuxalt.com/
Compares Windows software with Linux equivalents.

Linux App Finder
http://linuxappfinder.com
Search a large database of Linux Applications.

Open Source as Alternative
http://www.osalt.com/
Open source software alternatives to well-known commercial software.

OpenSuse Software Search
http://packages.opensuse-community.org/
Search for openSuse software that can be downloaded and installed with a click of a button.

Ubuntu Package Finder
