Imagineer Systems -- mocha Pro v3 Review
It’s Worth It
It bewilders me that after seven years of using After Effects, it wasn't until last year that I had even heard of mocha and further still, after noticing it already installed on my computer, it took me a few additional months to dig into it. While I could sum this up as having been too busy, the truth is that we are creatures of habit or perhaps I would have quickly embraced the prospect of making my work easier by learning this “new” tool. I typically don’t want to learn a new program unless I really feel it’s going to benefit my work quality or speed.
As an After Effects user, two things have dramatically changed the quality and speed at which I work over the last year: one of these is mocha, and the other is expressions. While the mocha to After Effects workflow does take some getting used to (and my wish list would include having mocha's short keys default to those of After Effects), the time invested in learning mocha has been worth its weight in gold.
Solving the Unsolvable
Imagineer’s mocha offers the ability to achieve matchmoves unlike any other software I’ve used due to its use of planar tracking. While it isn’t made to replace a 3D matchmoving solver like boujou or PFtrack, the latest release, mocha Pro v3, provides interesting new features that have helped me get out of a few jams. While supervising a music video we needed to composite dozens of shots that required a 3D matchmove but we only had 2-6 reference points for the solve. To make things even more difficult, these reference points were light bulbs that were continuously changing in brightness, making it nearly impossible to track with any point tracker. Initially I had hoped to track this in PFtrack, but PFtrack requires more than 20 points at any given time to create a solve, even manual tracking wasn’t an option. After Effects CS6 included a just released 3D camera tracker, but because the lights were constantly changing in intensity none of the trackers were able to stick for as long as was needed to provide a sufficient track. I was ready to just eyeball the shots when I came across mocha’s new 3D camera solver in mocha Pro v3. While I wasn’t able to solve for a 3D move with the lack of any vivid planar surfaces, I was able to use two to three position tracks to solve for a nodal pan camera move that I was able to import directly into After Effects and effectively fake a 3D move.
Recently, I was commissioned to do VFX on a commercial making animals talk. I had attempted this effect several years back but ran into huge issues with the tracking and was not pleased with my results. I knew that in order to achieve what I wanted, I would need to use real plates of the animals opening their mouths and manipulate it in way that would make them look like they were saying real words. Further, I realized that the effect would require tracking a base plate of the animal staying relatively still with its mouth closed and another plate of the animals opening their mouths.
Two challenges arise when tracking the animal’s face that would have proven near impossible without the use of planar tracking in mocha. First, the fuzzy nature of animal fur does not provide high points of contrast that are trackable with the point tracker like the one you find in After Effects. Instead, mocha’s planar track, tracks the entire pattern at giving me a near perfect track of both plates. Second, accurately matching the meshing and distortion resulting from the opening and closing of the kitten's mouth was facilitated through the use of shear tracking data offered in mocha allowing me to mask out the kitten's meow with an accurate matte.
Imagineer Systems made some big strides by approaching tracking/matchmoving in a new and exciting way. The speed and accuracy at which mocha can improve tracking and rotoscoping makes it a stand out: for both its feature set and the price point — free with After Effects ($1000 for mocha Pro). I can see this being a must have for all studios and freelancers needing tracking or rotoscoping with quick turnarounds and solid results.
