Simple Four-Channel Switching. The Blackmagic Design ATEM Mini HDMI Live Stream Switcher is a compact, tactile solution for switching up to four HDMI signals and the predecessor to the Blackmagic Design ATEM Mini Pro HDMI Live Stream Switcher. The switcher is capable of ingesting up to 1080/60p video, and it can send a 1080/60p program feed to a computer via USB Type-C.

Dual Audio Inputs. On the rear of the unit, you’ll find two 3.5mm mic inputs for mixing in auxiliary audio alongside the four HDMI inputs’ audio signals. Fairlight audio enhancements include compression, gating, limiting, and a six band EQ for tweaking each input.

Upstream Keyer & Transitions. An upstream keyer allows for luma, linear, pattern, and chroma keying while a built-in suit of transitions gives you the ability to cut, mix, dip, wipe, push, spin, squeeze, and swoosh your videos from one into the other.

Downstream Keyer. The downstream keyer allows you to add logos and titles from a built-in media pool to the program output. Use of this feature will require you to connect the switcher to a computer running ATEM software v8.1 or later. PNG, TGA, BMP, GIF, JPEG, and TIFF files are all compatible with the media player.

Monitoring. There is one HDMI output on this switcher, that can be configured to monitor a single program or single preview source. Please note, this switcher offers no multi-view support.
