“We use chroma key video to make our interpretive rangers in our studios in Anza-Borrego Desert State Park in Borrego Springs and the Seacliff State Park in Santa Cruz look as though they’re in any number of different environments throughout the park, such as of Año Nuevo, an island where elephant seals haul out to fight for the right to breed. Our rangers really are there in a sense, because the chroma key backgrounds are coming from live video streaming from those locations,” explains Brad Krey, the PORTS program manager.
“The students and teachers in each classroom are seeing all of this live, and they can ask questions in real time that can be answered on the spot by our rangers. If they see something on the screen that they want to see again, we can have the camera pan back live while the ranger answers the questions. We get to do this for thousands of students and teachers every year, most of whom would never get the chance to visit the California State Parks as a part of their K-12 education experience.”The PORTS program uses any number of video conferencing platforms, and all of the PORTS audio, video from the remote chroma key background locations, live cameras in the studios, and variety of other sources, is now routed and mixed using the Roland VR-4HD HD AV Mixer. “For instance, if a teacher in a classroom asks us about a particular aspect of the show, we can pull in audio and video from our YouTube channel that can show and explain things more deeply,” Krey explains. “But what makes this so incredible is than anyone on our staff can manage the A/V. We can mix and match sources on the fly and not need to have a degree in A/V technology to do it correctly every time...read more
