ProRes 4444 encoding comes to Sound Devices Pix Recorders

Written by David Shapton

Sound Devices/RedShark4:4:4 upgrade

Somewhat surprisingly, Sound Devices has added the ability to record 12-bit, 4:4:4 content to Apple ProRes 4444 format at 330 Mbit/s, giving a "perceptually lossless" quality to stored material

Why is it surprising?

Because it had previously been thought that this was too high a data rate for this type of recorder, although it seems that the Pix Recorders have always been equipped with the 3G flavour of SDI.

Optimised

Sound Devices has clearly been able to optimise their system to allow this level of recording, and of course SSDs are getting faster all the time.

Cameras with 4:4:4-capable outputs include the ARRI ALEXA, Canon C500 and Sony F3.

The firmware update is available free of charge to existing customers.

There are other detailed improvements which you can read about in the full press release below.

SOUND DEVICES HIGHLIGHTS NEW 4:4:4 FEATURE FOR PIX 240 AND 240i AT THE 2013 NAB SHOW
Video Recorders Can Now Record 12-Bit, 4:4:4 Content to Apple ProRes 4444
LAS VEGAS, APRIL 4, 2013 — For attendees in search of the latest 4:4:4 recording solutions, Sound Devices showcases its latest upgrade to PIX 240 and PIX 240i Production Video Recorders at the 2013 NAB Show (Booth C2849). This new major update, available for all PIX customers free of charge, offers Apple ProRes 4444 recording from video sources over 3G-SDI (4:4:4 RGB or YCbCr). Recording 4:4:4 offers productions superior color precision for applications in chroma-keying, color-grading and multi-generational editing.
 
PIX 240 and 240i users now have the ability to record into Apple ProRes 4444, which offers impressive quality with 4:4:4 sources and workflows involving alpha channel transparency. With its 12-bit, 4:4:4 capability, the PIX 240 and 240i can record 330-Mbps Apple ProRes 4444 files that are perceptually indistinguishable from the original source material. Popular cameras with 4:4:4 capable outputs include the ARRI ALEXA, Canon C500 and Sony F3.
 
“Sound Devices is pleased to feature this latest firmware update at NAB, as we know this is an important feature to many of our users and we foresee this capability being a hot topic at this year’s show,” says Paul Isaacs, Technical Development Manager, Sound Devices. “Bringing Apple ProRes 4444 recording over 3G-SDI to the PIX 240 and 240i offers additional color accuracy available in a 4:4:4 environment—reinforcing the PIX recorder as a master-grade production recorder suitable for the most demanding production applications.”
 
Additional features available in this latest v3.0 firmware update include time-code and recording status displays on the SDI and HDMI outputs, up to 500 ms of audio delay to compensate for multi-device picture delay, and selectable 4:4:4 or 4:2:2 video output independent from the source material.
 
Users can connect PIX 240 and 240i to cameras with HD-SDI, 3G-SDI, or HDMI and record directly to QuickTime using a range of different Apple ProRes or Avid DNxHD codecs, including Apple ProRes 4444. Since PIX recorders use ProRes and DNxHD, files recorded in the field can be used directly in post production, making for simpler, faster workflows.
 
The PIX 240i’s high-performance five-inch, IPS-based LCD display is an accurate field monitor, providing users with immediate confirmation of framing, exposure, focus,  audio metering and setup menu selections. It offers excellent color accuracy and contrast, great off-axis visibility and accurate motion tracking.
 
The built-in hardware scaler and frame rate converter allows PIX to output and record material at different resolutions and frame rates than supported by the camera. Conversion between HD and SD, with and without anamorphic conversion, is available.
 
The audio circuitry of the PIX recorders is based on Sound Devices’ award-winning 7-Series digital audio recorders. The low-noise (-128 dBu EIN), high-headroom, high-bandwidth inputs are mic/line switchable and include limiters, high-pass filters and phantom power.
 
The HDMI-only PIX 220 and PIX 220i video recorders also gain new features available in the new version 3.0 update, including Apple ProRes 4444 recording, time-code and recording status displays on HDMI outputs, and up to 500 ms of audio delay to compensate for multi-device picture delay.
