The open source video editor for Linux LiVES has been updated. It is a free, yet stable and powerful software package for editing digital videos.
It can also be used as a VJ tool for creating images and mixing visuals and music. It includes an RFX builder for creating effects and transitions, and can be extended through RFX plugins. LiVES handles most video formats and common audio formats. A long list of features and editing capabilities can be found on the LiVESweb site.
Another great open source video editor for GNU/Linux is Kino, which offers easy and reliable digital video editing and works well with IEEE-1394 to capture digital video and provide video tape recorder control.
You can use it for example to load several video clips, cut and paste pieces of video or audio, and save it as an edit decision list in SMIL XML format. Besides various DV formats, Kino can export to a variety of other formats, such as MP3, Ogg, Vorbis, MPEG-1,2,4, and WAV. It can also export still frames in most common image formats. For more information see here.
And then there is OpenShot, which includes an "Animated Title Editor" that is based on the open source 3D content creation software Blender. You can use simple tools for creating animated 3D title sequences for your movies.
OpenShot has been developed specifically for editing videos on Linux with the goal to make it easy for anybody to edit videos and produce high quality movies. It is a relatively new project but already comes with an impressive set of features. There are numerous transitions to choose from, and dozens of title schemes.
It supports many video, audio, and image formats, multiple tracks, clip resizing, trimming, and cutting, video transitions, real-time previews, image overlay, watermarks, title creation, and frame stepping. Some of the functionality, such as video encoding, is built on FFmpeg, an open source and cross-platform software package for recording, converting, and streaming audio and video content.
There are some 30 video effects, such as converting to black and white, and several audio effects, such as adding an echo. Ubuntu users can install OpenShot using the PPA (Personal Package Archive) system. For other distributions, there is a build wizard available that downloads and compiles the source code and dependent libraries.
