Gradient FX Relies on Mocha


Founded in 2006, Gradient FX is an award-winning artist and technology-driven VFX studio. Balancing the ideal blend of art and technology, Gradient FX mix their technological savvy with high design and artistry to deliver unconventional, yet visually stunning results for their clients. Gradient FX has over 30 feature films under their belts – from arthouse indies to global blockbuster films, as well as music videos, television commercials and game cinematics.

Gradient FX has also been an Imagineer Systems customer since mocha version 1.0, and have made it the primary go-to tool in their VFX kit.

Thomas Tanenberger, co-founder of Gradient FX explained that “It’s like an infrastructure tool for us now, our Swiss army knife for just about any and every challenging sequence we face.”

This summer, Gradient FX completed work on the romantic comedy, Friends with Benefits, starring Justin Timberlake.

“We used mocha extensively on Friends with Benefits,” said Tanenberger. “It’s a romantic comedy, so our ability to create moods and cinematic ambiance in post is critical. And mocha plays such an important role in scenes you’d never think would require a lot of work.”

He explained that in one sequence, Timberlake and Mila Kunis are on a New York City rooftop with the Empire State Building in the background. Director Will Gluck wanted a clear night sky with twinkling stars behind the actors. “Mocha made quick and easy work of rotoing the actors so we could replace the skies behind them. What would’ve taken hours, took only minutes.”

And with the ubiquity of smart phones and cell phones in our lives, it’s impossible to make a film today without replacing cell phone screens. In Friends with Benefits, so much of the interaction between characters is smart phone use – calling and texting constantly. And in a romantic comedy, it’s all part of the chemistry, mood and timing that needs to be maintained in a realistic way.

“Smart phones just don’t have the brightness and clarity to show up on the movie screen, so every single one of them needs to be replaced. We used mocha extensively for screen replacement throughout the entire movie – mocha makes it simple and fast and incredibly accurate – realism is key!”

And many post houses can relate to a director asking for what seems to be a simple request that ends up adding hours, if not days, to a project.

“One sequence that really stood out for us was the restaurant scene, where the actors were dining al fresco on the street,” explained Tanenberger. “It was a big shot, with the camera starting with a wide shot above the scene, craning down to narrow the focus onto the character. The directors wanted the shot flipped. Seems easy, right? Well, on a city street loaded with street signs, posters, images and graphics, it’s suddenly not that simple. Everything was inverted. Every sign with a written word on it was backwards and had to be changed. With mocha, tracking, roto and stabilization working together, we extracted all the signs, stabilized them and tracked it all back. This would’ve taken days of tedium, but with mocha, we made quick work of the shot.”

Seamless workflow becomes increasingly important to shops like Gradient FX. When time is of the essence and you have artists working on impossible deadlines, the last thing you need is integration issues between applications.

“In our workflow, mocha is often the ‘in between step.’ We do a lot of our work in Nuke, so our ability to export seamlessly from mocha to Nuke is critical,” said Tanenberger. “Mocha makes smooth work of this. Feature film postproduction is heavily pipelined, and teamwork is so important, so you also need tools that work perfectly in synch with each other.

“Without mocha, jobs like this would’ve taken days or weeks longer,” said Tanenberger. “It may not always be glamorous, but the tedium of manual frame-by-frame manipulation can become overwhelming. But with mocha central to our pipeline, it’s a life saver.”

Gradient FX was also involved in the postproduction of Harry Potter and the Deathly Hallows parts 1 and 2, Captain America, Dream House and The Change Up.

Vicon Introduces Mobile Mocap at SIGGRAPH

Motion capture systems developer Vicon is previewing a futuristic new “Mobile Mocap” technology at SIGGRAPH 2011 in Vancouver. Moving mocap out of the lab and into the field, Vicon's Mobile Mocap system taps several new technologies, many years in the making. At the heart of Mobile Mocap is a very small lipstick-sized camera that enables less obtrusive, more accurate facial animation data. The new cameras capture 720p (1280X720) footage at 60 frames per second. In addition, a powerful processing unit synchronizes, stores, and wirelessly transmits the data, all in a tiny wearable design.
