ATEM SDI mixers are very similar to ATEM Minis, but outdo them with 3G SDI video connections and twice as many video outputs. Take advantage of the four SDI inputs on the ATEM SDI and ATEM SDI Pro ISO models, and the eight SDI inputs on the ATEM SDI Extreme ISO model. All SDI inputs offer standard converters and resync! There is even DVE for picture-in-picture effects! The USB port acts as a webcam when connecting video sources to computers. The Pro and Extreme models are equipped with internal streaming hardware. For audio, the Fairlight Mixer has a compressor, limiter, parametric 6-band EQ and an expander on each input. A new generation of portable mixers for live productions! ATEM SDI mixers give you the portable design of the ATEM Minis, but thanks to SDI connections, they also work with feature-rich broadcast-quality cameras and recorders. This opens up new horizons for highly mobile live production. With this incredibly portable design, a complete broadcast-quality live production system can be stowed in a small bag or backpack. So you can use multiple cameras on set and stream live directly to YouTube, or create a broadcast-quality studio link via an ATEM Streaming Bridge. Unlike remote shoots with a single camera, you can create visually interesting remote interviews with multiple perspectives using multiple cameras connected to an ATEM SDI.
