Introducing Thunderbolt

Thunderbolt is the next-generation high-speed I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port. It sets new standards for speed, flexibility, and simplicity.

Imagine being able to connect a high-resolution display, uncompressed broadcast quality video I/O, and super high-speed storage to your Apple MacBook Pro, Mac Pro cylinder, or Thunderbolt-equipped PC, using a few Thunderbolt cables. With the HDX-SDI, that dream is now a reality.

Thunderbolt cable

Thunderbolt is the fastest, most versatile I/O format ever devised. It offers:

  • Massive bandwidth — 10 Gbps for data (12x FireWire 800) plus 10 Gbps for DisplayPort
  • Daisy-chaining — connect up to six high-speed, high-bandwidth devices
  • Bidirectional performance — massive input and output for your computer
  • Bus power — 10 watts of bus power to drive connected peripherals
  • Flexible connectivity — electrical or optical Thunderbolt cables with lengths up to 30 meters

The ultimate Thunderbolt video interface

Connect any video source to the HDX-SDI, from SD camcorders to today’s latest professional HD cameras, then log and capture HD or SD clips directly into your video editing software.

Full Raster

For the best-possible image quality, capture uncompressed video via HD-SDI or HDMI with 4:2:2 10-bit color depth and full-raster 1920x1080 HD resolution. Many cameras feed their uncompressed SDI, HDMI or component output directly from the camera’s optics and imager, before compression, for absolutely pristine picture quality during capture with the HDX-SDI.

Go ahead, choose your workflow

If you prefer to edit more conveniently at a lower data rate, use Apple ProRes, ProRes HQ, Avid DNxHD, or the codec of your choice in Avid Media Composer, Apple Final Cut Pro, or Adobe Premiere Pro. Because the HDX-SDI delivers 10-bit uncompressed video to the computer, you are not limited to a particular codec and are instead free to go with the host-based workflow of your choice, including many popular file-based formats now supported by today’s video editing software.

By using a codec directly supported by your editing software, you eliminate unnecessary extra stages of compression and decompression for maximum CPU efficiency and smooth editing.

As you edit, monitor your timeline with pixel-for-pixel accuracy on a large plasma screen via digital HDMI output, with color-corrected balance on an LCD reference monitor via HD-SDI output, or with the real-world look of a consumer display via analog HD or SD component, composite or S-Video output.

Putting the Audio back in AV

Capture and monitor up to 16 channels of audio (analog, AES/EBU or embedded) at sample rates up to 96 kHz. Employ Sony 9-pin machine control for advanced Batch Capture and Edit to Tape operations. Keep everything frame-accurate using time code and video reference.

Audio I/O

From initial capture to final finishing, the HDX-SDI delivers exceptional video I/O performance and quality.
