    How to make the most of your Brompton Processor

    How to make the most of your Brompton Processor

    When you first get to use the Brompton Tessera system, you may not be aware of all the options available to make your LED screen work optimally for your particular environment.

    The Tessera software includes default options such as ChromaTune, Dark Magic, Advanced Genlock with Phase Offset, and OSCA (On Screen Colour Adjustment), as well as features enabled per panel type such as High Frame Rate (up to 144Hz) and Studio Mode.

    These features will allow you to achieve better low-brightness performance, improved on-camera performance and superior overall visual colour accuracy.

    With ChromaTune, you’ll be able to tweak an individual colour with colour replace, or you can tweak an array of 12 colours and black &white with the 14-way colour corrector, to get the image on screen looking the way your client wants it to look. With OSCA, you can correct variances between different batches of LED panels or within the same batch that have aged differently. Apart from colour matching, OSCA also allows you to correct the seam brightness of adjacent panels and modules.

    Dark Magic and Studio Mode are designed to improve low-brightness performance. In the case of Dark Magic, using temporal and spatial dithering can remove banding in dark areas when you have reduced the brightness of your panels or when you have content with gradients from bright to dark. On panels with Studio Mode implemented, you can also improve low-brightness performance by reducing the current gains of the LEDs and capping the brightness of the panel at a pre-determined level, thus increasing the number of steps of brightness available when the panel brightness is lower.

    Since our 2.3.1 release, we introduced Advanced Genlock with Phase Offset and Frame Rate Multiplication. Using this, you can improve on-camera performance to ensure the screen refresh is in sync with the camera sensor’s frame capture period. In some cases, Frame Rate Multiplication will improve the chance of the camera sensor picking up the entire frame.

    No matter your requirements, we are sure that Brompton has a feature that can assist in delivering a world-class production. If ever in any doubt, our technical support team are available 24/7 to answer your questions on
