FiLMiC has patented a brand new high-efficiency picture remapping expertise, Cubiform.
The newly-patented Cubiform is ‘an strategy to making use of a remap to every pixel in a picture.’ Cubiform generates colour look-up tables (C-LUTs) utilizing a dynamic set of parameters, which might then be modified by customers in real-time. Through the use of C-LUTs moderately than immediately modifying photographs, a stream of C-LUTs will be utilized to a picture, or sequence of photographs, with out putting excessive demand upon the CPU or GPU.
FiLMiC says that by eschewing per-pixel processing for chrominance and luminance modifications, Cubiform adjusts colour and brightness utilizing C-LUTs, which ‘lookup’ new values from a pre-calculated desk. FiLMiC writes, ‘This strategy is considerably extra environment friendly for complicated remap operations because the C-LUT is handled as a static data-model and discarded if a distinct remodel is desired.’

When modifying utilizing Cubiform picture processing expertise, image-transform parameters are manipulated in real-time, which leads to decrease picture high quality. Nevertheless, the decrease picture high quality is barely a consequence when edits are occurring. As soon as edits are full, Cubiform generates a high-precision C-LUT, which FiLMiC states produces a high-quality picture remap.
Simply how a lot quicker is Cubiform? Almost 5 instances quicker, per FiLMiC. A activity {that a} conventional GPU pipeline completes in 26.4 milliseconds will be achieved utilizing Cubiform in 5.6ms. If you’re rendering resource-intensive video, reminiscent of a protracted 4K clip, Cubiform’s positive aspects are vital.

FiLMiC Inc. CEO Neill Barham says, ‘FiLMIC’s Cubiform expertise not solely represents a major technological development in picture processing, it additionally represents our deep dedication to forwarding cell cinema digital camera {and professional} cell images innovation. All the crew at FiLMiC acknowledges the accountability we’ve got to our clients, and to the business. That is not nearly making nice apps, that is about enabling a wholly new era of filmmakers and photographers, and to try this effectively calls for superior technological sophistication and class. We’re extraordinarily pleased with this contribution.’

The Cubiform patent is only one of FiLMiC’s current developments and improvements. Final September, an replace to FiLMiC Professional added clear HDMI output to Android and iOS units, giving customers new choices for recording and livestreaming. Simply over a yr in the past, FiLMiC’s Double Take app allowed for multi-camera recording. In November 2019, the corporate branched out from simply video with FiLMiC Firstlight, a nonetheless images software for cell units.
