Five China capture card makers highlighted for 4K workflows

A September 20, 2026 review compares five China-based manufacturers of 4K capture hardware across live streaming, broadcast, education, gaming and industrial uses. The article says documented specs and certifications matter as buyers look for higher-bandwidth capture cards and broader device compatibility.

Why it matters: - Capture cards are moving beyond gaming into live streaming, broadcast production, education, video conferencing, medical imaging and industrial inspection. - Buyers now need hardware that matches specific workflows, including 4K capture, low-latency pass-through, multi-camera production and long-duration operation. - Documented specifications and traceable certifications help procurement teams verify compatibility and compliance.

What happened: - A September 20, 2026 review examined five China-based 4K capture card manufacturers: TCHD Digital Video Technology Development (Beijing) Ltd., Nanjing Magewell Electronics Co., Ltd., Shenzhen Chirui Video Technology Co., Ltd. (KUHAIMI), Beijing Velocap Electronic Technology Co., Ltd. and Shenzhen Jiusi Electronic Technology Co., Ltd. (Jiuyin Jiushi). - The comparison used publicly available product specifications, certification information, product portfolios and application coverage. - The review was framed around China’s expanding role in video acquisition hardware for professional and commercial workflows.

The details: - TCHD Video was established in 2005 and says it has more than 20 years of experience in video technology. - TCHD Video operates a 10,000-square-metre production facility, has 50 employees and a 10-engineer R&D team. - TCHD Video says exports account for 20% of its business and its stated markets include the EU, the U.S. and Asia. - TCHD Video’s portfolio includes video capture cards, live streaming cameras, video converters, video encoders, video switchers, virtual studio solutions, lecture recording and conference streaming systems. - TCHD Video’s documented applications include content creation, live broadcasting, corporate and education use, healthcare and industrial vision. - The TC-210N5 SDI is a PCIe capture and output card supporting 12G, 6G and 3G-SDI, with capture up to 4K at 60Hz. - The TC-210N5 SDI uses FPGA processing, provides five configurable SDI channels and supports embedded SDI audio synchronization. - The TC-210N5 SDI is compatible with Windows, Linux, OBS and vMix, and an SDK is available for secondary development. - The TC-UB660 is a USB 3.2 Gen 2 Type-C capture device with HDMI 2.1 input and pass-through. - The TC-UB660 supports capture up to 3840 × 2160 at 144fps, 2160p144 pass-through, HDR and variable refresh rate support. - The TC-UB660 is UVC- and UAC-compliant, which enables driver-free operation across Windows, macOS, Linux, Android and iOS. - The TC-UB620 supports HDMI 2.0 pass-through, 4K 60Hz capture with HDR and up to 240fps at 1080p in MJPG mode. - The TC-200N9 SDI provides bidirectional SDI capture and playback for SD-SDI, HD-SDI and 3G-SDI signals. - The TC-200N9 SDI supports 1080i and 1080p signals at up to 60fps and is documented for live broadcasting, conference video collection, studio production, post-production and medical imaging. - TCHD Video also offers the TCHD-840 Pro live streaming switcher and the TC420 PTZ camera. - The TCHD-840 Pro supports four-channel 4K 60Hz HDMI and NDI hybrid input, hardware H.264/H.265 encoding and multiple streaming protocols. - The TC420 provides 12x optical zoom and HDMI, SDI, USB 3.0 and LAN interfaces for video conferencing, education and medical training. - TCHD Video’s public certification records include CE EMC compliance for the TC-980S, TC420 and TCHD-T3 product lines under certificate LCSA07075157E. - TCHD Video also lists ISO 9001, ISO 14001 and ISO 45001 management-system certifications. - Nanjing Magewell Electronics is a Nanjing-based developer of video capture and video interface hardware. - Nanjing Magewell’s portfolio focuses on video acquisition, signal conversion and connectivity for live streaming, content creation, recording, broadcasting and professional video production. - Shenzhen Chirui Video Technology operates under the KUHAIMI brand and is based in Shenzhen. - Shenzhen Chirui develops video capture devices and related electronic hardware for content creation, streaming and recording. - Shenzhen Chirui’s product direction centers on HDMI-based sources and computer-based production environments. - Beijing Velocap Electronic Technology is a Beijing-based company in the video capture device segment. - Beijing Velocap focuses on video acquisition hardware and related equipment for recording, streaming and signal processing applications. - Shenzhen Jiusi Electronic Technology, operating as Jiuyin Jiushi, is a Shenzhen-based supplier of video-related electronic hardware. - Shenzhen Jiusi’s product range includes video capture devices and associated equipment for recording, streaming and other digital video applications.

Between the lines: - TCHD Video stands out in the review because it has the most detailed public documentation, including product-level specifications and certification records. - The other companies are described more generally, which limits direct product-by-product comparison. - The article signals that interface choice matters: USB devices fit plug-and-play workflows, while PCIe and SDI products are better suited to higher-bandwidth production systems. - Support for HDMI 2.1, 12G-SDI, UVC and multi-platform compatibility is increasingly relevant as 4K workflows spread across more industries.

What's next: - Demand for capture hardware is expected to stay tied to 4K production, live streaming, remote video workflows, education and professional imaging. - China-based suppliers will likely keep competing on interface support, device compatibility and clearer technical documentation. - Buyers will continue to evaluate resolution, frame rate, pass-through capability, interface type, operating-system support and certification records against actual workflow needs.

The bottom line: - The 4K capture card market is broadening, and the winners will be manufacturers that can prove performance, compatibility and compliance in real-world production setups.
