Fusion is a massive new release with features specifically designed for the latest virtual reality, visual effects, motion graphics, and 3D workflows! The entirely new VR toolset makes Fusion indispensable for virtual reality projects, while new camera and planar tracking features make it possible to precisely track and composite objects while maintaining perspective and camera motion. Fusion also includes delta keyer, with advanced image science that makes it the world’s most advanced keyer. In addition, you also get Studio Player which includes new multi user collaboration tools for tracking and managing shots, along with version history, annotation notes and more!
As with other manufacturers in the film and broadcast area, the term “VR” is a little misused as they are really referring to “360 video.” VR, although a more exciting term, would demand interactivity. That said, as a post production suite for 360 video, Fusion already has a very strong tool set. It can create, manipulate, texture and light 3D scenes made from imported CGI models and built-in primitives and particles. Added in Version 9 is a spherical camera that can capture a scene as a 360 2D or stereo 3D image. In addition, new tools are provided to cross-convert between many 360 video image formats. Another useful tool allows a portion of a 360-degree image to be unwrapped (or un-distorted) so that restoration or compositing work can be easily carried out on it before it is perfectly re-wrapped back into the 360-degree image. There is also a new stabilizer for 360 wrap-around shots. A neat feature is that Fusion 9 can directly drive VR headsets such as Oculus Rift. Within Fusion, any node can be routed to any viewing monitor and the VR headset simply presents itself as an extra one of those.
Notably, Blackmagic has opted not to tackle 360-degree image stitching — the process by which images from multiple cameras facing in different directions are “stitched” together to form a single wrap-around view. I can understand this — on one hand, there are numerous free or cheap apps that perform stitching and so there’s no need for Blackmagic to reinvent that wheel. On the other hand, Blackmagic targets the mass user area, and given that 360 video production is a niche activity, productions that strap together multiple cameras form an even smaller and decreasing niche due to the growing number of single-step 360-degree cameras that provide complete wrap-around images without the need for stitching. Moving on from VR/360, Fusion 9 now boasts some very significant additional features. While some Fusion users had expressed concerned that Blackmagic was favoring Resolve, in fact it is now clear that the Fusion development team have been very busy indeed.
First up is an embedded camera tracker and solver. Such a facility aims to deduce how the original camera in a live-action shoot moved through the scene and what lens must have been on it. From this, a camera tracker produces a virtual 3D scene into which a compositor can add objects that then move precisely with the original shot.
Fusion 9’s new camera tracker performed well in tests. It requires the user to break the process down into three logical steps: track, refine and export. Fusion initially offers auto-placed trackers, which follow scores of details in the scene quite quickly. The operator then removes any obviously silly trackers (like the ones chasing around the moving people in a scene) and sets Fusion about the task of “solving” the camera move.
Once done, Fusion presents a number of features to allow the user to measure the accuracy of the resulting track and to locate and remove trackers that are adversely affecting that result. This is a circular process by which the user can incrementally improve the track. The final track is then converted into a 3D scene with a virtual camera and a point cloud to show where the trackers would exist in 3D space. A ground plane is also provided, which the user can locate during the tracking process.
While Fusion 9’s camera tracker perhaps doesn’t have all the features of a dedicated 3D tracker such as SynthEyes from Andersson Technologies, it does satisfy the core need and has plenty of controls to ensure that the tool is flexible enough to deal with most scenarios. It will certainly be received as a welcome addition.
Next up is a built-in “planar” tracker. Planar trackers work differently than classic point trackers, which simply try to follow a small area of detail. A planar tracker follows a larger area of a shot, which makes up a flat plane — such as a wall or table top. From this, the planar tracker can deduce rotation, location, scale and perspective.
Fusion 9 Studio’s new planar tracker also performed well in tests. It assessed the track quickly and was not easily upset by foreground objects obscuring parts of the tracked area. The resulting track can either be used directly to insert another image into the resulting plane or to stabilize the shot, or indirectly by producing a separate Planar Transform node. This is used to warp any other asset such as a matte for rotoscoping work.
