4K Multi-interface Video Encoder

All Your Interfaces, One Professional 4K Encoder

E3

4K Multi-interface Video Encoder

E3 is a new-generation professional video encoder that combines powerful performance and flexibility in a compact unit. It supports HDMI input up to 4Kp30, 3G-SDI input up to 1080p60, and USB input, encoding in both H.264 (AVC) and H.265 (HEVC) formats. E3 can encode either HDMI or SDI video independently, or combine both in PIP (Picture-in-Picture) or PBP (Picture-by-Picture) modes.

Designed for professional IP-based workflows, E3 supports a comprehensive range of protocols including NDI HX3/HX2, SRT, RTMP/ RTMPS, RTSP, HLS, WHIP, TS over UDP, and RTP, with support for up to 8 concurrent streams.

H.265 Encoding with 50% Bandwidth Savings

E3 supports HEVC (H.265), enabling up to 50% lower bitrate compared to H.264 without sacrificing image quality. This reduces network load and ensures stable transmission, even under limited bandwidth conditions—while maintaining excellent visual fidelity.

Multiple Inputs, Flexible Encoding

The E3 features 4K ​HDMI, 3G-SDI, and USB inputs​ (HDMI/SDI support loop through),enabling it to be flexibly applied in either broadcast level production or pro-AV scenerios.

E3 can support seamless switching among three inputs and encode either source independently, or it supports simultaneous encoding from both inputs up to 1080p60, even it support for PIP (Picture-in-Picture) from HDMI and SDI inputs.
