Alchemist Live

Motion-compensated Frame rate Conversion for Live Media Streams

Alchemist is recognized throughout the world as the undisputed gold standard of motion compensated frame rate standards conversion. Alchemist Live builds on this legacy and offers the very best motion compensated frame rate conversion, providing transparent, artifact-free conversion for seamless global distribution of live media.

Available in two operational modes: as a single channel for 4K UHD conver-sions or three channels for HD/3G conversions, Alchemist Live can also sup-port either SDI workflows or IP SMPTE ST 2110/2022-6 applications with 10/40 GbE or 25/100 GbE interfaces. Supported IP features include PTP timing to SMPTE ST 2059, single stream 4K HD, SMPTE ST 2110-20...
