Zero-lag passthrough


ZowieBox can capture your game in 4K with zero passthrough, and it can convert RGB, YCbCr 444/422 into a universal live broadcast format. This allows ZowieBox to support various computer monitors with HDMI video output, in addition, pass-through video can maintain the original video quality.

ZowieBox supports HDCP input, no need to set up on the game console.

ZowieBox can support up to 1080p120 or 4K60 and supports HDR10/HDR12/Dolby zero-latency live broadcast. It can downsize 1080p120 or 4K60 to 1080p60, and can also live stream and record 1080p60 videos while playing games. 1080p60 is the most widely used live broadcast resolution.

Standalone streaming without PC and capture card 


ZowieBox is a professional-grade live broadcast device, especially suitable for independent game video live broadcasts.  ZowieBox won’t cause any FPS issues like frame lag, skipped or dropped frames while live streaming and recording gameplay on PC, MAC, mobile and consoles.

Without a PC and capture card, the game can be directly broadcast through the gigabit network. At the same time, NDI game videos are also shared on the LAN.

Gaming playing and streaming in real-time


NDI’s low-latency and high-definition connectivity technology is perfect for multiple gaming industry applications from a streamer’s home setup to a global e-sports championship live stream. Through NDI, users can directly send audio and video to OBS, vMix for live broadcast, and each PC could be the monitor without any capture card and cable connection.

Easily join the NDI world


NDI offers the most flexible and efficient formats, enabling any production to set up workflows easily. The high-quality and ultra-low-latency of NDI®| HX3 are even better than USB capture. The decoding capability of ZowieBox is an easy way to distribute streaming video or NDI® | HX3 on the network, decode and route to HDMI, then output to a screen or project.

Convert any HDMI video to NDI video


ZowieBox can be flexibly mounted on any SLR camera using a ¼-unc standard tripod. Any existing video signal, such as a professional camera or HDMI monitor, can be converted into a real-time, low-latency, high-quality IP video stream that supports NDI.


Mobile phone screens only require a simple USB C to HDMI adapter cable, and mobile games can also be captured via ZowieBox.

Powerful encoding and decoding


ZowieBox can encode formats such as H.264 HP/MP/BP, H.265/HEVC MP, NDI, NDI|HX2 and NDI|HX3 as well as SRT, RTMP, RTMPS or RTSP protocols whose bitrate could be up to 50 Mbit/sec. Simultaneously it can directly push streams to multi-platforms such as Facebook, Twitch and YouTube, without a PC.  Alternatively, these IP streams could decoder into high-quality HDMI outputs.
