Colorfront will debut HFR Frame-Blending at HPA 2015Colorfront will debut Interactive HFR Frame-Blending during HPA’s 2015 Tech Retreat, February 9-13 in Palm Springs, California. The company says it enables real time control over the motion blur of objects in an HFR sequence.

The demo will use Alexa ArriRaw footage, shot at 120FPS with an open shutter, being deBayered in 4K on the fly. Using a simple slider interface, this new capability allows users – both on-set and in post-production – to incrementally adjust shutter angles on HFR footage between 72º and 360º, and to perform real time frame blending. Along with providing control over motion blur, this new capability also delivers the ability to retime shots and create speed ramps – with the results being seen immediately, playing back in real time.

Colorfront Interactive HFR Frame-Blending supports a wide range of digital cameras that can shoot 120FPS HFR Raw/ProRes footage, including Arri Alexa, Red Epic, Canon C500, Sony F55/F65, Panasonic VariCam 35 and AJA Cion. It is available in Colorfront On-Set Dailies and OSD Transkoder 2015, Colorfront’s automated, standalone system for high-quality digital file conversion.

“The majority of current digital cinematography cameras can now shoot up to 120FPS, but the small number of available toolsets to manipulate HFR material are typically limited to slow, non-interactive desktop systems,” said Aron Jaszberenyi, managing director of Colorfront. “Working closely with productions shooting in Hungary, we noticed a trend to shoot more and more footage at 120FPS, and were able to rapidly develop an interactive system that takes advantage of Colorfront’s high-performance Raw processing technologies to adjust Raw HFR footage on-the-fly. This new capability allows cinematographers and digital creatives to shoot at 120FPS with a full open shutter, to interactively 'dial in' the motion blur, make creative decisions regarding shutter angles, frame rates and motion blur, and watch the results in real time, without the need to wait for rendering.”
