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.

Multi-Protocols, More Streams Simultaneously

E3 supports a complete range of streaming protocols including NDI HX3 / NDI HX2, SRT, RTMP / RTMPS, HLS, TS over UDP, RTSP, WHIP, and RTP. It supports up to 8 destinations simultaneously, making it possible for live production with NDI HX, remote production with SRT, live streaming with RTMP or any transmission with all different protocols at the same time.

Applications

With its advanced chipset and HEVC compression, E3 delivers high-quality video at lower bitrates—ideal for broadcast, education, house of worship, sports, and more.
