LILLIPUT AVMATRIX Shark Series 4-CH SDI/HDMI Video Switcher - Compact

In this review of the LILLIPUT AVMATRIX Shark Series 4-CH SDI/HDMI Video Switcher the bottom line is simple: it is a compact, capable switcher aimed at small broadcast crews, houses of worship, educators and independent live streamers who need flexible inputs, direct recording and built-in streaming without a lot of extra gear. The reviewer found the unit particularly useful because it combines two HDMI and two 3G-SDI inputs with a 10.1 in FHD IPS multiview, USB-C capture and RTMP/SRT streaming in a single box, making multi-camera 1080p60 workflows straightforward for on-location and studio use.

Key Features

• Multi-format inputs: Two HDMI and two 3G-SDI inputs let users mix consumer cameras and professional SDI sources without adapters, simplifying camera choices for a live set.
• Direct streaming and capture: Built-in RTMP/SRT over Ethernet plus a USB-C capture output allow streaming to platforms and capture to a computer with common software such as OBS or vMix.
• Onboard recording: USB-A recording to an SSD or flash drive and a built-in SD card slot enable program recording in MP4 without needing an external recorder.
• Advanced keying and overlays: Upstream luma and chroma key, picture-in-picture and downstream logo overlay provide the compositing tools needed for presentations and live shows.
• Audio mixing: Embedded audio from HDMI and SDI plus two analog mic/line inputs and audio delay offer practical audio routing and clean live mixes.
• Flexible outputs and monitoring: Two HDMI program outputs, a multiview HDMI out and configurable AUX outputs let producers route clean program, preview or color bars as needed.

Who It's For

The Shark Series switcher is best for small production teams, houses of worship and educators running multi-camera 1080p60 programs who want integrated streaming, recording and multiview monitoring in a compact chassis. It suits users who need both HDMI and 3G-SDI connections and who value built-in chroma key, PiP and a media library for quick graphics and transitions.

Those who need native 4K switching, very large-scale input counts, or specialized broadcast routing beyond four channels should look at larger studio systems instead. Also, users who require touchscreen operation or extensive hardware fader automation may prefer a different control surface.
