AJA Hi5 HD-SDI/SDI to HDMI Video and Audio Converter

The AJA Hi5 is a compact, professional-grade bidirectional converter that seamlessly translates between HD-SDI/SDI and HDMI video signals, while also handling embedded and analog audio. This portable device is a vital tool for video professionals working in field production, broadcast, post-production, and live events, where interfacing equipment with different video standards is a daily challenge. It allows users to connect a camera or recorder with an SDI output to an HDMI monitor, or conversely, feed an HDMI source like a laptop or graphics machine into an SDI-based production switcher or router. The Hi5 is renowned for its rugged all-metal construction, plug-and-play simplicity, and reliable performance in demanding environments.

Despite its small size, the Hi5 incorporates sophisticated signal processing. It automatically detects the input signal format—supporting standards from standard definition SDI up to 3G-SDI for 1080p60—and converts it with high quality, maintaining color space accuracy and minimizing latency. A key feature is its comprehensive audio handling; it can extract embedded audio from the SDI stream and output it via the HDMI connection, and it also includes a 3.5mm stereo mini-jack for analog audio input or output, providing flexibility for different audio workflows. The device is powered via a USB connection, which can be sourced from a computer, a USB wall adapter, or even some monitors, making it highly portable and eliminating the need for a separate power brick in many scenarios.

The AJA Hi5 is built to withstand the rigors of production life with a durable, shielded casing that protects against electromagnetic interference. Its straightforward operation requires no configuration; simply connect the input and output cables, provide power, and it begins converting. This reliability and ease of use have made it a trusted accessory in countless production kits. By solving format conversion problems instantly and transparently, the Hi5 ensures compatibility across hybrid video systems, enabling creatives and engineers to focus on production rather than technical connectivity issues
