Flicker is ubiquitous in high-speed and ultra-high-speed nighttime recordings. The cause is high-frequency fluctuations in lighting sources installed in most venues world-wide. Replacing all lighting sources with non-flickering sources such as appropriately installed LEDs is usually not an option.
We have researched this issue since 2008 and have come up with an ingenious software/hardware solution that postprocesses video in real-time to remove flicker, and which can be easily integrated into broadcasting workflow. An earlier prototype system has been successfully deployed world-wide by a small German company for several years

This new deFlicker is a complete reimplementation of this earlier prototype that was improved in many ways over the original. Major improvements include a two-level watchdog timer to ensure maximum unattended availability, a rigorous testing protocol that ensures stable performance even under suboptimal thermal conditions, multiple redundancy levels in hard- and software such as mirrored ECC memory, mirrored SD-cards, redundant power supplies, and a completely redesigned user interface that can also be used via on-screen-display and even ensures that the output stream is always smooth and never jerky regardless of parameter settings.
