Chapter 1: Introduction
Overview
TruZoom provides real-time 4K/UHD recording, playback, and region of interest (ROI)
selection with timeline-based keyframeable control. The power of the TruZoom system
provides unsurpassed flexibility and performance for recording, assembling, and playing
back real-time sports, lecture hall/panel discussions, or courtroom video.
You can eliminate the need for multiple cameras minimizing space and cabling
requirements by using TruZoom with a single, UHD 4K camera coupled with region of
interest selection and playback.
The TruZoom system consists of:
• An AJA Corvid Ultra processing unit
• One or two TruScale scaling engines
• A control panel with joystick
• The TruZoom application software.
The control panel and software operate with a qualified high-performance customerfurnished Windows workstation, including a RAID for high data-rate recording and
playback. (If you use the system for live ROI extraction only, without record or playback, a
RAID is not required.)

Region of Interest
(ROI) Example
The following three figures depict:
• a full-frame 4K video source
• the TruZoom computer screen showing a selected RO
• And the resulting SDI video.
In this example the final ROI SD video image is presented at HD 720p resolution.

Corvid Ultra Processor Frame Installation
Optionally
Reversing the Rack
Ears
The unit can be installed so the connectors face the front of the rack, by reversing the
rack ears on each side of the frame (Figure 9).
Figure 9. Reversing the Frame’s Rack Ears
Rack InstallationIf the frame is installed immediately above other equipment in a rack, the rubber feet on
the bottom of the frame may need to be removed for clearance.
CoolingInternal air flow is directed by fans through the signal processing frame. From the front
HIB Installation and
Cabling
(LED indicator side) of the frame, the air flow direction is from right to left (Figure 10).
Figure 10. Cooling Airflow Direction
Do not obstruct the side vents, and allow sufficient space within the equipment rack for
airflow to and from the sides of the frame.
Caution! Use anti-static practices whenever handling circuit board components, to
prevent possible damage from static discharge.
1. With the PC powered off, and using anti-static practices, open the chassis of the host
PC and install the Corvid Ultra HIB into a Gen 2 x 8 lane slot, or better.
2. With both the host PC and the Corvid Ultra frame powered off, connect the PCIe
cable between the two units.
TruZoom v1.1www.aja.com

Other System
Cabling
With the Corvid frame power still off, connect the reference, video, and audio cabling as
required for your application (Figure 11).
Figure 11. Corvid Ultra System Connections
Warning! The expansion bays are used for factory installed options only. Do not
remove the expansion bay covers for any reason.
Reference SignalAny reference signal should be terminated (75 Ohm) or if looped through should be
terminated at the end of the reference signal chain.
Canon RAW Input
Cabling
IMPORTANT:Camera connections to Corvid Ultra must be made as follows:
TruZoom can take input in RAW format from Canon C500 cameras. When the camera is
configured for 24, 25, or 29.97 fps, a single cable is connected to the Corvid Ultra frame.
When the camera is configured for 50 or 59.94 fps, then two cables are connected.
• Camera output 3G-SDI-1 connects to input SDI 1 on the Corvid Ultra
• Camera output 3G-SDI-2 connects to input SDI2 on the Corvid Ultra
If these cables are crossed, video frames will be recorded and play out in the wrong order.

Video OutputsThe Corvid Ultra Video signals on the output BNCs vary depending on the configured
output format and number of scalers installed. See “Video Output” on page 31 for more
