Overview

OG-4K2HD is an openGear card that down-converts professional 3G-SDI 4K/UltraHD signals to HD resolution using AJA’s high-quality scaling for cost-effective monitoring and conversion. OG-4K2HD’s HD-SDI and HDMI outputs are live simultaneously, producing fantastic-looking HD images for on set monitoring or direct-to-air broadcast.

OG-4K2HD supports high frame rate (HFR) 4K/UltraHD inputs at 50 and 60fps and converts to HD outputs at 50 and 60fps for accurate viewing. OG-4K2HD’s configuration options allow extraction of an HD resolution image from the 4K input to provide a one-to-one pixel image for 4K focus checks on HD displays.

Designed for use in high density openGear 2RU frames including AJA’s OG-X-FR frame, new DashBoard Software support on Windows®, macOS® and Linux® offers remote control and monitoring of the openGear architecture and provides convenient and industry-standard configuration, monitoring and control options over a PC or local network.

Real time downconversion

OG-4K2HD uses real time processing and AJA’s high-quality scaling algorithms to downconvert professional 4K or UltraHD signals using 4× SDI connections to HD resolution, producing fantastic-looking HD images for on set monitoring or direct-to-air broadcast.

Simultaneous HD-SDI and HDMI outputs

OG-4K2HD’s HD-SDI and HDMI outputs are live all the time, allowing use of both professional SDI monitors as well as low-cost HDMI monitors simultaneously. No matter what monitors you have on hand, OG-4K2HD can use them for on the spot 4K viewing.

High frame rate support

Many 4K productions are opting for higher frame rates of 50 and 60fps. OG-4K2HD supports high frame rate (HFR) 4K inputs and converts the HD output to a matching frame rate for accurate viewing so what you shoot is what you see.

Center-cut extraction

OG-4K2HD can be configured to extract an HD resolution center cut from the 4K input. This provides a one-to-one pixel image that can be used to check focus on 4K shoots without the need for a full 4K monitor.

openGear Compatibility

The openGear standard ensures that AJA cards will be compatible with other openGear products from certified openGear partners. With a growing list of products, openGear is the future of rackframe products.

Flexible I/O

The modular rear panel allows custom I/O connections per card (included with individual cards).

Failsafe

The optional redundant power supply provides a secondary power source in the event of a primary power failure.

Ethernet Access

A standard Ethernet connection allows the frame to be accessed via the Dashboard application for overall frame communication. Optional per-card Ethernet access can be installed in the frame for advanced communication with compatible openGear cards.
