S2 is an UHD 4K video encoder which is designed to meet the needs of all 4K video transmission applications.
The input resolutions is up to 4Kp60 and encoding resolutions is up to 4Kp30. It supports H.265 (HEVC)/H.264 high-performance encoding and most protocols including NDI|HX/SRT/RTMP/RTMPS/HLS/UDP/RTSP/Onvif.
With H.265 HEVC encoding, S2 offers a lower encoding bitrate and with a reduction of more than 50% bandwidth comparing with H.264. （Typical encoding bitrate: H.265: 4KP30@4Mbps，H.264: 4KP30@8Mbps）
4K Transmission Ensures Better Image Quality
With the HDMI 2.0 input, S2 supports 4Kp60 HDMI and encodes up to 4Kp30, and is compatible with SD/HD/VESA.
S2 Supports SRT/NDI/NDI|HX
S2 supports RTSP/RTMP/RTMPS/HLS/TS-UDP/Onvif1.1/2.0/ and NDI|HX, so users can live stream with RTMP/RTMPS, produce live content with NDI|HX and manage remote productions with SRT, at the same time with one device.
The S2 can be used in broadcast television, ProAV, live streaming and other video IP transmission applications, interactive connections, video network recordings, and integrated media projects.
Audio & Intercom
Audio and intercom are both embedded and 3.5mm analogue line in audio is also supported.
Together with Kiloview intercom software, S2 can support intercom functions for enhanced communication. (Supported in software version 2.0+)
Real-time monitoring and preview of the video
The newly-designed Web UI works perfect to preview the video source in real-time, allowing you to monitor the video status at any time.
Live streaming to 16 platforms simultaneously
Dual stream output (main stream and sub stream) - each stream can be sent to 8 platforms with the same or different protocols, altogether S2 can simultaneously live stream to 16 streaming platforms. Main stream resolution up to 4KP30Hz, sub stream resolution up to 1080P60.
It's a Recorder!
S2 features USB out capacity for local or NAS recording, storage and playback for video while streaming.
Image and text overlay, wherever you like
You can overlay LOGO/text/pictures to any position of the screen. At the same time, professional operations such as rotation/cropping, mirroring, and color adjustment are also available. (Supported in software version 2.0+).
