The Tessera processing system is genlocked from the video input all the way down to the LED refresh cycle, giving perfectly smooth video with no dropped or doubled frames.
The LED panels always refresh at an exact multiple of the input frame rate, with inputs of 23-60Hz supported. Tessera processors will automatically compensate where the source frame rate and the internal refresh rates are different for a smooth, reliable sync.
A Tessera SX40 or M2 LED Processor can be locked to any one of its video inputs, bi-/tri-level sync input, or internal timing reference
A Tessera T1 LED Processor can be locked to either the video input or internal timing reference
A Tessera S4 LED Processor automatically locks to the video input
From Tessera firmware v2.3 onwards, you can choose “Active Input” on the Tessera SX40 processor, meaning the genlock signal will come from whichever input source is currently active
Genlock can be used to lock the processor refresh to a camera’s shutter. This provides a better on-camera performance, by preventing the unsightly rolling black bars seen on video walls using free-running systems.
Alternatively, you can use Genlock to lock multiple Tessera LED processors together for completely seamless shows with no tearing. The processor can even add extra delay should it need to match with other slower video systems.
From Tessera firmware 2.3 onwards, it’s now possible to multiply the incoming genlock signal by a factor between x2 and x6.
At x2, LED fixtures can run at 60fps while still maintaining genlock, to achieve the best possible combination of good on-camera performance and smooth perceivable motion.
