Developed for film and television post and VFX facilities, boujou has long been the industry standard for matchmoving, allowing users to add computer-generated effects seamlessly into film or video footage. When boujou was first introduced in , it provided a completely different approach to motion tracking. Before boujou, matchmoving was an expensive and highly skilled process, adding significantly to post-production costs. Everything had to be done by hand in key-frame animation, or with laborious point-based camera tracking.

Boujou created quite a storm when it released its first version of its automatic image tracking software. While others were using manually finding 8 to 12 trackers to match move shots, boujou produced a revolutionary fully automatic tracker that used hundreds of trackers to automatically track shots. Version 2 contains intervention capabilities include features designed to maximise the potential of the automated tracking engine for solving tough shots.
Gold Tracks allows animators and composite artists to give priority to individual feature tracks created by the automatic tracking engine, by the new interactive frame-to-frame tracking feature. Boujou 2 also introduces new workflow enhancements. To deal with changing conditions within a shot, users can apply different parameters to subsets of frames, and track sections of the shot in any order.
These features are particularly important when camera moves contain widely varying types of motion or when the much of the scene is obscured in part of the shot. To assist an iterative workflow, boujou2 re-tracks only the subsets of the shot after parameters have been adjusted, and then automatically joins all the sections into one continuous solve when the shot is finished.
An example of this is if the frame was to flash to white during a flare, or have a sudden motion blurred camera hit or shake. One very helpful points for new users is the Informationals. Informationals help users understand how best to approach a tracking task, and how different approaches can be combined to achieve optimum results.
Boujou2 includes support for compositing software including Flame, Inferno, Cineon and After Effects. It runs on Linux — Red Hat 7. At Siggraph the demonstration took hand held video footage of a building and patched together a final matte painting, with all the moving objects in the foreground such as cars, digital removed.
Pixel Dust is an automatic matte generating and image repair program, not dissimilar to the work of MoKey. The product was demonstrated with the background replacement of a degree panning shot of a stadium, where the foreground actor was removed. The way the product works is to track and then seamlessly composite sections of background that are visable into position when that part of the background is hidden by the foreground element.
Of course if a section of the background is never seen in the clip, then the software can not replace it. The system therefore works best when there is a lot of frames and the camera or the forground is moving. To achieve high quality results, the replacement patch that is tracked in, is blended and colour corrected to match its surrounding original background.
For the right shot this automated process could save hours if not days of conventional compositing and hand tracking. While no dates have been release, FXGuide understands that it will be released next month at Siggraph and will be fully shipping by the end of the year. What will be interesting is to see if and how these hard core specialist applications are handled by the larger equipment manufacturers in the coming 12 to 18 months.
