The Open Movie Editor is only available for Linux and compatible Free and Open Source Operating Systems. It is provided only in the form of Source Code, as is the case for most Linux and FLOSS Software. The download is free, and there is no registration or money or anything involved. Be aware though that usage terms for this software are as explained by the GPL, the GNU General Public License v2 and later. The terms are very liberal, and promote the freedom to use this program in almost all ways possible.
