PiTiVi is a free software non-linear video editor licensed under the terms of the GNU Lesser General Public License,[1] primarily developed by Collabora. PiTiVi is designed to be a simple video editor to meet the needs of users in the GNOME desktop environment.

History

Edward Hervey started working on PiTiVi in 2004 as an end-of-studies project at the EPITECH engineering school in Paris.[2] Initially written in C, the PiTiVi code base was rewritten in Python eighteen months later.[3]

After his graduation, Edward was hired by Fluendo to work on GStreamer for the following two years,[3] after which Edward co-founded Collabora's Multimedia division in order to improve PiTiVi, GStreamer and the GNonlin plugins.[4] Collabora has since then hired two additional employees to help develop PiTiVi.

In the past there have been several video editors available for Linux, but, they were considered difficult to use.[5] Jono Bacon reviewed this situation stating "Back in 2006, the video editing situation was looking far more exciting. Michael Dominik was working on the hugely exciting Diva project and Edward Hervey was working on PiTiVi. Both combined exciting technologies, being built on the formidable foundations of GTK, GNOME, GStreamer and Cairo. Diva was developed using Mono, and PiTiVi using Python. With the video buzz in the air, Michael and Edward both demoed their projects at the Villanova GUADEC to rapturous applause."[5]Jono also notes that PiTiVi has taken a long time to mature, noting that "For Edward to have created the first incarnation of PiTiVi he needed to ensure that GStreamer and GNonLin were mature and stable enough to use for his application."[5]

Features

PiTiVi inherits its capabilities for importing and exporting (rendering) media from the GStreamer framework, or plugins for the GStreamer framework. PiTiVi supports simple media editing capabilities such as trimming, snapping, splitting and cutting of clips. Audio mixing is supported by curves, visualised as line segments drawn over an audio waveform. PiTiVi has the ability to step through a piece of media using scrubbers or keyboard shortcuts. Audio and video clips can be linked together, and treated as a single clip. Initial support for video mixing (compositing and transitions) has been added in late 2009 but is still under heavy work. A more exhaustive list of features can be found on the PiTiVi website.[6]

Jean-François Fortin Tam gave a talk at Libre Graphics Meeting 2009, discussing how usability became a major focus for the PiTiVi project,[7][1] and how design considerations impacted PiTiVi's user-interface, with examples such as the use of subtle gradients in timeline objects, drag and drop importing and direct manipulation, native theme integration, and reducing complexity by carefully evaluating the need (or lack thereof) to impose preference choices onto users.[7]

The PiTiVi project also has a user manual that covers the usage of the application. PiTiVi has been translated and localized for several languages by the GNOME translation teams (il8n).

Through GStreamer, PiTiVi is the first open source video editor to support the Material Exchange Format (MXF).[8][9]

Development

Collabora Multimedia employs Edward Hervey, Brandon Lewis and Alessandro Decina to improve on PiTiVi and the GStreamer and GNonlin frameworks.[10][8][11] Development has also been funded through the Google Summer of Code program.[12]

Media attention

In an interview with gnomedesktop.org Edward Hervey discussed the state of PiTiVi and Linux Video editing; at one stage Edward notes that "there's a total lack of cohesion between all the various multimedia applications/libraries/device-support on linux which is IMHO the reason why we're not yet the reference platform for multimedia creation."[13] This point of view is further expanded on in another article showing Edward believes that "if the Linux desktop was going to have a nice and easy to use video editor any time soon, we needed to do something to increase the pace of development significantly."[14] In order to speed up the pace of development Collabora decided to increase the PiTiVi team to include three to four members.[14]
