CineTreak Stream Master SDI CineTreak

Podrobný popis

The CineTreak Stream Master SDI is a hybrid switcher with a flip-up 10″ screen, four 3G-SDI inputs and four HDMI inputs; it handles any combination of up to four live sources at once. One aluminium body combines switching, PTZ camera control, graphics, Full HD recording, USB-C UVC, an SDI output and simultaneous streaming to two RTMP destinations.

A hybrid switcher for HDMI and 3G-SDI

The ten-inch console connects up to four live sources in any combination from eight inputs – 4× HDMI and 4× 3G-SDI. Switching, graphics, PTZ control, recording and streaming all happen right in the unit.

SDI for broadcast cameras, HDMI for everything else

Connect professional cameras over 3G-SDI and photo cameras, a computer or a games console over HDMI. The switcher with eight inputs works with any combination of up to four sources.

Two RTMP streams at once

The built-in H.264 encoder streams over LAN to two RTMP destinations, such as YouTube and Facebook, without a streaming computer.

Recording and streaming together

The program is saved in Full HD to an SD card or a USB drive, with a bit rate separate from the stream.

Up to four PTZ cameras

Control via VISCA over IP: zoom, focus and stored presets right from the switcher.

Chroma key, PIP and DSK

Luma key and chroma key, two PIP windows, POP mode, DSK and two logos – up to eight layers in the program.

Flip-up 10″ screen with multiview

The flip-up ten-inch HD screen with a wide colour gamut shows the live status of all channels in real time: preview, program, four inputs, AUX and the media library. The director sees the production from several angles without an external monitor, and the flip-up design makes work easier on a desk and on location.

Buttons, T-bar and transitions

Two rows of program and preview buttons, a T-bar, AUTO, CUT and FTB give you confidence when switching live. Available transitions include WIPE with multiple patterns, MIX and DIP, plus transition preview, background, freeze frame (STILL) and audio mute (MUTE).

HDMI and SDI in any combination

Four 3G-SDI inputs (HD-3G Level A, YCbCr 4:2:2, 10-bit) and four HDMI inputs can be combined freely, with up to four live sources at a time. HDMI inputs 1 and 2 accept up to 2160p60. They are complemented by AUX, a background, the media library and the Down Streaming function for another video source from the network.

Landscape and portrait streaming

The switcher offers two live streaming modes. For social media, simply turn the cameras to portrait and switch the mode – the stream then leaves in 9:16. One setup serves classic broadcasts and mobile platforms alike.

Two RTMP streams and a USB-C webcam

The built-in stream engine streams over Ethernet to two destinations at once, with no computer attached. The USB-C (UVC) port puts the switcher into webcam mode: video and audio go to a computer for OBS, vMix, Teams, Twitch, YouTube, Skype or VLC at up to 1080p60.

Recording to an SD card or USB drive

The SD card slot and the USB-A port record the program output (PGM) in Full HD as MJPEG at up to 32 Mb/s. Recordings can be played back at any time, even during a broadcast, and recording runs alongside the stream with a separate bit rate.

PTZ camera control

The switcher controls up to four PTZ cameras with the VISCA protocol over IP: recall zoom, focus and stored presets right from the panel, without a separate controller.

Customised PIP and POP

Two picture-in-picture (PIP) windows and POP mode with adjustable size, position, zoom and cropping combine the host, a presentation and a remote guest in one picture. Built-in transition effects round out the toolset.

Keying, captions and logos

Chroma key and luma key replace green or blue backgrounds, and the DSK adds captions and graphics to live and recorded video. Two logo layers accept a PNG image with transparency up to 940 × 540 px; the program combines up to eight layers.

Connectors

The rear panel carries power, LAN, USB-C for the webcam, an SD card slot, USB-A, HDMI outputs (program and AUX) and SDI, four HDMI inputs, four 3G-SDI inputs, two microphone inputs and an audio output.
