The FeelWorld ATEM156 can be used as a companion to switchers that don't have a multiview function, such as the Blackmagic ATEM Mini switcher. It allows you to view four DCI/UHD 4K HDMI signals in a quad split. Four HDMI loop outputs let you connect your four signals to the switcher. You can move any signal to any window in the quad split. A PiP image can also be displayed in each window. Alternatively, a dual view or single image can be displayed on the screen, also supporting Picture-in-Picture. Dual view can be set up in a vertical or horizontal split, and you can set one side of the split to be larger than the other.Add up to 1080p60 wireless video transmission to your gimbal, mirrorless, or DSLR camera rig using the lightweight Mars 400S PRO SDI/HDMI Wireless Video Transmission System from Hollyland. The transmitter provides HDMI and SDI inputs and the receiver offers SDI and HDMI outputs. It features extremely low 0.1s latency with line-of-sight transmission up to 400' to the receiver and up to 300' to the Hollyview Wi-Fi app. For a strong line-of-sight signal, the system includes two external antennas on the transmitter and two on the receiver, and one is included as a spare. Using the Hollyview app for iOS or Android, you can monitor your video transmission in real time via a Wi-Fi connection as well as live stream directly from the receiver via your computer using a USB Type-C adapter. The app also allows you to install optional channel scanning firmware enabling you to easily find the strongest transmission signals. The transmitter can simultaneously transmit to up to one receiver and two apps, or to a total of four apps without the receiver. The redesigned body makes it a low-profile choice for your rig, and it features multiple fan modes to keep it cool or quiet when you are shooting.
