review Pixel Farm’s PFMatchit T By JIM GEDULDICK DI/Visual Effects Artist Co-leader AENY New York filmbot@mac.com A node-based matchmoving solution. racking/matchmoving applications have come a long way in the past decade, from inter nal propr ietary tools at major visual effects shops to cost-ef- fective solutions that ev en the one-man shop can run on his desktop or laptop. SIG- GRAPH this year brought us a sneak peak at a new matchmoving solution called PF- Matchit from The Pixel Farm, who offer visual effects, DI and restor ation solutions in the form of PFTrack and PFClean, to name a few. I personally have been using PFTrack for the past few years and was eager to take a look at the new, lower-priced but feature- packed PFMatchit. A NEW NODAL APPROACH When you launch PFMatchit one of the first things you will notice is the node-based flowgraph architecture, a new way of ap- proaching matchmoving from other pack- ages and even the current version of PF- Track. If you are used to using a nodal-based compositor like The Foundry’s Nuke or Au- todesk’s Flame you should be right at home and up and running in no time with this new approach to tracking. I have favored working hardware recently, which is why it is no sur- prise that The Pixel Farm has made PF- Matchit 64-bit native on Mac OS X, Win- dows and Linux. For the initial tests of PF- Matchit, I was running on a Mac Pro dual 2.8 8 core with an Nvidia GTX 285 and 16GB of RAM running OS X 10.6 in 64-bit (previ- ous Mac’s did not boot into 64-bit natively PRODUCT: Pixel Farm’s PFMatchit WEBSITE: www.thepixelfarm.co.uk PRICING: Node-locked license, US $700; PFMatchit annual support and mainte- nance, US $140 · 64-bit node-based architecture · scriptable, allowing for workflow customization · feature rich and low cost · GPU-accelerated optical flow tracker while running OS X 10.6). Setting up some footage to track was extremely easy with a few tracking markers in the scene.While al- lowing the software to analyze and solve, I kept a close eye on my system resources with some processing monitor s and PF- Matchit was saturating as much of the cores and GPU as I could throw at it. Anyone who does tracking will tell you, de- pending on the scene loaded, the solve can take quite a while . PFMatchit was cranking through my tracking duties with quick turn around and solid camera solves. THE TOOLSET Besides the new node- based architecture in PF- Matchit, you can see some of The Pixels Farm’s deep understanding of its user base and cutting A nodal-tree view makes it easier to see what’s going on in your comps. in the nodal UI ever since learning Shake years ago.

If you have ever used PFTrack you will know exactly how solid the solves are with Pixel Farm’s under- lying algorithms. Matchmovers everywhere need to have manual control over certain aspects of the package they are using. In this case the new Edit Camera Node has been my absolute favorite feature of PFMatchit. It allows man- ual control over camera settings letting you www.postmagazine.com flow tracker. I tend to let PFMatchit auto track first, then go back in, depending on the solve, and manually edit parameters or then keyframe/hand track. Some of the other notable tools are the built-in rolling shutter cor rection, which plagues all CMOS-based cameras we see in post and visual effects with the labeled “jello cam footage.” For me, being a long time Red camera user, getting access to Red RAW without having to transcode is a very big feature.This allows for the utmost highest quality being fed to the tracker. Stereoscopic review tools and lens dis- tortion tools pla y hand in hand in PF- Matchit. When you have monocular dis- crepancies (issues differing between eyes like distor tion, dust or scratches on the lens) it is great to not have to jump to an- other package to deal with these issues. This ties into PFMatchit’s Matte and Roto tools for removal of said lens issues in 2D and 3D stereoscopic. FINAL THOUGHTS The Pix el Far m has tak en some big strides with approaching tracking/match- moving in a new and exciting way.The per- formance increase and stability that PF- Matchit delivers makes it stand alone not only in its feature set but also in the price point — $700. I can see this being a must have for all studios, boutiques and free- lancers doing any type of visual effects and 3D animation w ork needing tr acking/ matchmoving with quick turnarounds and solid results. tweak your animation path of the camera while being able to use the intuitive hints as to how the camera moves.This can be really helpful when tracking shots with trouble- some issues or even in the case of having no tracking markers in the scene at all.
