This article covers SDI キャプチャーカード USB 3.0 SDI.

Overview

The Groza SDI Capture Card is an external USB 3.0 device that captures SDI video signals up to 1080p60. It features an HDMI loop-out port for zero-latency local monitoring, making it a practical tool for live streaming and recording. Thanks to UVC/UAC compliance, it works as a plug-and-play webcam on Windows, Linux, and macOS without extra drivers. Positioned as an entry-level capture solution, it balances affordability with reliable SDI support.

Connectivity & Compatibility

The host interface uses USB 3.0 with a throughput of 300–350MB/s, although it is backward compatible with USB 2.0 at reduced bandwidth (~40MB/s). For stable 1080p60 capture, a USB 3.0 port is strongly recommended. Input is a single BNC 3G-SDI connector supporting SD-SDI, HD-SDI, and 3G-SDI formats. Outputs include an HDMI loop-out (up to 1080p60) and a USB 3.0 video stream. The USB output resolution can be set from 640×360 to 1920×1080 at frame rates of 30, 40, 48, 50, 59.94, or 60fps. The device is compatible with Windows, Linux, and macOS. It is recognized as a standard UVC/UAC device, so it works out of the box with OBS Studio, VLC, Zoom, and other streaming/recording software.

Product Info

Released around 2021, this capture card is still available through retailers like . Pricing hovers around ¥18,000–¥20,000. Warranty varies by seller but typically one year. The package includes a USB 3.0 cable, an HDMI cable, and a quick-start manual. Market positioning is entry-level to mid-range: it offers a straightforward way to bring SDI cameras into a PC workflow without breaking the bank, but it does not support 4K or high frame rates beyond 60fps.

Best Use Cases

Live streamers: Anyone using an SDI camera (e.g., DSLR/mirrorless with HDMI-to-SDI converter or professional camcorder) can feed the signal into OBS with loop-out monitoring. The plug-and-play nature minimizes setup time. Beginner video creators: Those new to SDI recording can capture footage directly to disk without complex drivers. It's a cost-effective alternative to higher-end capture cards for 1080p projects. * Single-camera production: If your workflow uses one fixed SDI camera for recording or streaming, this card is a compact and affordable choice. Avoid if you need multi-input switching or 4K/120fps capture.
