There are instructions on how to go about this on. Unfortunately installing the alpha of Pitivi 0.92 on Ubuntu 13.10, for example, is a bit of a performance. The only stable release version of Pitivi available in the Ubuntu Software Center is version 0.15.2 and this really does not give a good idea of where the Pitivi project is going.

Despite some effort, we were unable to install anything other than Pitivi 0.15.2, which looks very different. Even a white to pale-grey palette, as used by many of the FOSS video NLEs, can skew contrast perception.Ī screenshot of Pitivi 0.91 from the Pitivi website.

Not long ago Adobe overhauled its flagship imaging products along these lines, using a dark charcoal palette for the bulk of the interface. In practice, this limits the design of the ideal user interface for image manipulation applications to different shades of dark grey, with small areas of saturated spot colour used to highlight status and control elements. The theoretical ideal for any imaging application is to use a muted neutral colour palette for the elements of the user interface. Because of the effect of simultaneous contrast, areas of saturated colour in the user interface of any image manipulation application can affect perception of colours within the image that's being manipulated. It is quite a challenge to design an attractive, efficient user interface for a video NLE that also presents the user controls and menu options so that they're unobtrusive and yet easily found when needed. The longest running FOSS projects that have managed to attract a larger number of developers offer the most mature and well-rounded applications, but generally are struggling to keep up on features and often have unsophisticated, dated-looking user interfaces. Commercial developers, such as Adobe and Apple are (just about) able to keep up with these developments, but charge a correspondingly high price for their top-end products. The recent and rapid growth in the development of higher-quality, higher-resolution digital imaging technologies - new camera file formats, 2K, 4K and even 8K resolutions and stereoscopic 3D - adds further complications to the development of video NLE software that's in tune with current needs, particularly in the professional market. Projects tend to start off with a basic function editor, with the aspiration of creating a more capable product as the release cycle progresses. For developers of FOSS video NLE (Non Linear Editing) software, the choice is arguably determined by available development resources.
