With up to 12 stops on the iPhone XS Max, FiLMiC Pro and the Cinematographer Kit transforms the latest devices into the ultimate cinema camera
FiLMiC’s new LogV2 is a quantum leap in high end mobile video imaging with up to 2.5 extra stops of dynamic range. Log V2 works on all iOS devices, and most Android camera 2 API capable devices and is part of our high end Cinematographer Kit in-app purchase.
The flat and Log gamma curves in the Cinematographer Kit give filmmakers all the latitude they need for color grading data rich content for spectacular results.

As the lines between professional cinematic cameras and mobile devices continue to blur, LOG V2 for FiLMiC Pro elevates the mobile filmmaking experience by delivering up to 2.5 stops of additional dynamic range for mobile devices.
LOG V2 enables the XS and 11 series devices to exceed 12 stops of total dynamic range at base ISO. These results rival those of high-end cinematic cameras such as the Blackmagic Pocket Cinema Camera and the Panasonic Lumix GH5s.

How do we achieve the impossible and deliver up to 2.5 extra stops of dynamic range?
LogV2 is the culmination of years of work done on a proprietary computational-imaging module that we internally call “Cubiform”. Cubiform creates a mathematical environment where we can process the luma and chroma of an image with 64-bit precision.
In the case of LogV2, we use this high-precision environment to construct a luma-map from the 8-bit source. Because the luma-map is derived from a flattened 24-bit RGB vector, the resulting fidelity exceeds the 8-bit precision of the individual Red, Green, and Blue elements. This high quality luminance information allows us to reconstruct the gamma of the identity image using a process called ‘gamma vectorization’. After this operation is complete, we map the 64-bit scalar representation of the image into an 8-bit container for publishing to our encoder. The result, as you have seen, is dynamic range and tonal coherence that seemingly bypasses the sparse data-point problems associated with traditional 8-bit gamma augmentations.
With LogV2, we have chosen to abandon linearization and embrace the dynamic nature of the iOS pixel buffer stream. Instead of attempting to perfectly linearize the image, we modify the native gamma with a delta-augment that results in a spline that resembles a tradition log base 2 profile. Because iOS tone mapping is still active, the gamma spline will occasionally take on sigmoid characteristics. LogV2 produces an image with non-linear saturation: it is greatest at the mid-tones and progressively decays as the luminance approaches the black or white points.
On Android devices supporting Gamma Curve Remapping we take advantage of this tool to provide a custom LOG curve at the sensor level. This allows us to greatly expand the dynamic range of the sensor during the first stages of the camera pipeline. The resolution of this Gamma Curve is device dependent and could vary from 16 to 512 remap points, however in FiLMiC Pro we don’t allow less than 32 to ensure superior quality.
For those Android handsets that do not support Gamma Curve Remapping, we apply the same technique as iOS which is detailed above.
