With the RTX Broadcast Engine, NVIDIA has introduced an interesting solution for live streamers that uses AI algorithms on GPUs with tensor cores to enable some nice video effects in real time. Among other things a few Style Transfer Filters have been integrated, but most of them have already been seen in the past.
One of the most interesting features is the RTX Greenscreen, which can separate the background from a human moderator without the background having to be "green". Because the RTX Greenscreen Key also works quite well against any background. NVIDIA will present the feature at Twitchcon 2019 and make it available via OBS in a few months.
Almost as exciting (and not to be confused with Adobe&s Character Studio) is the RTX AR SDK. It can recognize a face in a live camera and track features like eyes and mouth. Played facial expressions can be transferred live to a 3D character.
All functions are still "only" available via the SDKs, but any manufacturer can now integrate them into their own programs.
