LiVES

Here is another opensource video editing application LiVES (Linux Video Editing System). LiVES mixes realtime video performance and non-linear editing in one professional quality application. It will let you start editing and making video right away, without having to worry about formats, frame sizes, or framerates. A very flexible tool which is used by both professional VJ's and video editors - mix and switch clips from the keyboard, use dozens of realtime effects, trim and edit your clips in the clip editor, and bring them together using the multitrack timeline. You can even record your performance in real time, and then edit it further or render it straight away.

The GUI is based on gtk+ 2.14+, runs under KDE, Gnome, Metacity, Fluxbox, Compiz and any known window manager.LiVES can also be scripted to be used as a video server. Can load single images or directories of images in numerical order and assemble them into videos or slideshows.
LiVES is available in the synaptic of Ubuntu 11.04.
