The Ultra-Versatile Encoder/Decoder/Recorder/Converter – All In One!

The Vela Rack SDI from Science Image is a versatile, multipurpose video production tool that works equally well as a video encoder, decoder, recorder, and format converter. The Vela Rack SDI is small in size, taking up only about a third of a rack unit in space, while still including a full-color LED touch screen, tally light, SSD recording bay, and a full complement of SDI, HDMI, audio, and network connections.

Example Workflows

The Science Image Vela Rack SDI has many uses in live production. These are a just a few possible workflows:

  • Encode SDI video signals up to 4Kp60 to High-Bandwidth NDI, NDI|HX2, or NDI|HX3.
  • Decode NDI video to SDI outputs, while simultaneously monitoring the signal on the built-in display and outputting via HDMI to an external monitor.
  • With two Vela units, capture SDI video on the first unit, transmit the via fiber to the second unit, which then encodes that SDI signal to RTMP for a live stream.
  • Record NDI video to the internal SSD drive while decoding it to an SDI output.

Although the Vela Rack SDI can be used as a standalone unit, with the optional Vela Shelf up to three of these devices can be installed in a single 1RU of rack space.

Key Features:

  • Multifunctional 12G-SDI video encoder, decoder, converter, and media recorder
  • 3.4-inch touch-screen display with live video monitoring and user-interface control
  • Simultaneous encoding and decoding capability
  • Supported formats: RTMP, RTSP, SRT, High-bandwidth (Full) NDI, NDI|HX2, NDI|HX3
  • Encode, decode and record up to 4K 3840×2160 @ 60fps and up to 10-bit 4:4:4 quality
  • Front-panel 3.5mm stereo audio jack for intercom and stream monitoring
  • 12G-SDI input, 12G-SDI loop-out, HDMI2.0 output
  • Optical SFP+ interface for optional Science Image T1 12G-SDI fiber transceiver
  • USB 3.0 port for external PTZ control
