The NDI Studio 4K.SH from Science Image is compact and rugged bi-directional NDI video encoder and decoder. The Studio 4K.SH features both 12G-SDI and HDMI 2.0 connections for both input and output, making it capable of both encoding and decoding Full NDI video at up to 2160p60.

The large built-in tally light is also controlled by NDI, making the Studio 4K.SH even more handy in a live production environment. Additionally, the device includes a USB PTZ camera control port, allowing it to receive PTZ commands over NDI even if the camera itself is not NDI compatible.

For audio input and output, the Studio 4K.SH has stereo audio line-level input and headphone output, both using standard 3.5mm (1/8″) jacks.

This useful device also works as a versatile format converter with Up/Down/Cross conversion of 27 types SMPTE and PAL/NTSC standard formats, with more formats available in the future by way of firmware updates.

To quickly view the device’s settings, a convenient 1.3-inch OLED screen displays the unit’s working status and parameters, input/output format and other content in real time.

The NDI Studio 4K.SH has built-in HDMI 2.0 and 12G-SDI optical transceivers for sending and receiving video signals over long distances. Users can choose different optical modules to transmit different distances, with the maximum support of 20 kilometers.
