Brompton releases Tessera v3.4 software

Two major feature advances form part of Brompton Technology’s Tessera v3.4 software release. Extended Bit Depth unlocks higher PWM bit depth output with a free firmware update for all existing and new panels fitted with the Brompton R2 or R2+ receiver card. Up to 3.3 additional bits of precision improves low-brightness performance, reducing visual artefacts and bringing out additional detail and nuance in dark areas of the image. This increase in dynamic range is said to offer a significant boost in performance for ICVFX and other LED on-camera applications.

With Extended Bit Depth, users can also reproduce HDR content up to 10 times darker than previously possible, without compromising peak brightness for HDR highlights. When configured for use on camera with a shutter angle of 180°, calibrated measurements confirm that a typical 2,160-nits panel using Extended Bit Depth and Dark Magic can render brightness levels as low as 0.00024 nits, just 0.000011% of the peak brightness. It does not reduce the peak brightness of the panel, so HDR highlights can still be displayed to their full potential, resulting in a contrast ratio of over 9,000,000:1 and over 23 stops of dynamic range.

Stacking, which is available on Tessera SX40 and S8 processors, allows multiple processors in a setup to be controlled together in unison. Any setting adjustment made on the leading processor will be automatically applied to all the others in the stack, saving users time as they don’t need to apply adjustments to each processor individually. It is also possible to customise which parameters will be synchronised across the stack, giving flexibility to suit a wide variety of applications, including both backup (failover) processors and control of large LED volumes. Multiple stacks of processors can co-exist on a single LAN, allowing for versatile setups with quicker and greatly simplified control.
