TruZoom™

Unparalleled Real-Time 4K

AJA’s new TruZoom™ application and Corvid Ultra hardware come together in a revolutionary system for unparalleled real-time 4K recording, scaling, playback, and high-quality Region of Interest selection with AJA TruScale image processing and complete timeline-based keyframe control.

Recording

In addition to larger frame sizes, productions are also moving towards higher frame rates to achieve smoother motion and more immersive experiences. Frame rates of 48, 50 and 60 are becoming more common while simultaneously increasing frame size to UltraHD and full 4K.

To meet these increasing demands, TruZoom is able to input a wide range of video formats from 720p to 1080p, 1080i, UltraHD and 4K as well as Canon C500 RAW data, all at up to 60 frames per second to accommodate whatever workflow you are presented with.

Incoming video signals are saved to the local disk array as native resolution DPX files. These DPX files can be played back within TruZoom, and with the Canon RAW option the incoming RAW camera data is debayered in realtime for the highest possible image quality.

Live Scaling

In live environments such as sports broadcasting and event production, a single 4K camera can be used to capture a wide shot of the venue. From this 4K image, TruZoom can extract a Region of Interest and scale that to HD resolution for use in HD broadcasts or recording. This allows more complete coverage than with multiple cameras and the flexibility to reframe the shot after the fact for total flexibility. In situations where the area of interest is predictable, preset regions can be saved and recalled quickly, mimicking the technique of switching between multiple cameras on the fly.

TruZoom’s responsive controls allow realtime manipulation of the Region of Interest for quick and easy isolation of key events. AJA’s TruScale arbitrary scaling hardware provides the power to scale any Region of Interest while maintaining the most pristine image quality possible.

Playback

The user interface for TruZoom allows complete keyframe control over the Region of Interest selection. Indicators in the interface show the exact Region of Interest for precise selection using the external joystick and mouse controls.

Recorded files can be played back from the local drive array and a Region of Interest can be selected just like a live feed, but with the ability to create keyframed variable speed playback and holds of the footage to highlight a particular event. And since the Region of Interest can be manipulated live, you can create realtime pan and scan effects for live broadcast or event production.

Corvid Ultra

AJA’s Corvid Ultra provides the realtime input, processing and output for TruZoom. The extensive I/O connections can handle 3G, HD-SDI, 4K-SDI and 4K HDMI with embedded and AES audio capabilities, supporting video formats from SD through 4K at up to 60 frames per second and color depth up to 16-bit half float RGBA with full color space conversion.

The high-quality AJA TruScale™ hardware expansion card provides incredible quality at any resolution and the RAW debayering option allows Canon RAW files to be played back in real time. Communication to the host computer is via an 8x PCIe host adapter at 2500+ MBs in each direction.

TruZoom™ System Configuration Guide

TruZoom has a very specific set of system requirements to ensure proper operation of the application. The currently supported components and configurations are listed below. You can choose a supported workstation and storage configuration to create a customized TruZoom system.

This webpage contains the most up-to-date information regarding TruZoom system configuration. Additional configurations will be added here as they are qualified by AJA.

Workstations

Several PCIe cards will need to be installed in the TruZoom system such as the GPU, Corvid Ultra HIB and the RAID controllers.

HP z820

The HP z820 Dual Proc system with Windows 7 installed is certified for use with TruZoom. There are several qualified configurations. Choose one of the options from the following chart and install the cards into the recommended PCIe slots on the system’s motherboard.

  Option 1 Option 2 Option 3
Slot 1 Empty Empty Empty
Slot 2 GPU GPU GPU
Slot 3 Empty/Covered by GPU Empty/Covered by GPU Empty/Covered by GPU

Storage Options

There are several options for local storage with TruZoom. Each of the approved options are summarized here. Choose one storage configuration and install the appropriate hardware in the TruZoom system.

Internal SSD RAID Configuration

RAID Controller

The tested and approved RAID Controller for TruZoom is the LSI 9271-8iCC Raid Controller. Detailed product information can be found on the LSI website:

http://www.lsi.com/products/raid-controllers/pages/megaraid-sas-9271-8iCC.aspx

The LSI RAID controller must be configured for RAID 5 as detailed in the LSI Configuration section below.

Drive Tray Module

The drives for the RAID must be housed in a special SAS/SATA drive tray module. The Athena Power drive tray module is the approved device for this configuration:

http://athenapower.com/node/99

Each drive tray can house four (4) SSD drives. Since a total of eight drives are needed, two drive trays are required to be installed.

Drives

For local storage of video files, eight (8) Intel SSD drives are required. Each drive must have a capacity of 240GB or higher and all drives in the RAID must be of the same capacity. Intel SSD drives with capacities below 240GB are not supported at this time.
