Adaption of ProAV-optimized Colibri codec

In the main use case of ProAV, preserving high quality of complex graphical content poses a significant challenge. The new Colibri codec has been specially designed to bridge this gap, providing seamless distribution and delivery of high-quality complex graphical content for 4K60 over 1GbE. The ADTECHNO Dante AV Ultra incorporates this newly optimized video codec to flawlessly encode any graphical content while preserving visually lossless quality for video.


* Interoperability requires consistency in the video codec used on both the encoder and decoder.


Perfect Synchronization of Audio and Video

Dante AV Ultra employs a single clock to synchronize seamlessly with one another over the network using the IEEE 1588 Precision Time Protocol (PTP), delivering sub-microsecond synchronization. 

Imperceptible subframe latency


Dante AV Ultra streams and transport video and audio content with highest performance and lowest latency - 4K60 with 8ms or less latency


Fast, seamless switching between video sources
