Capture cards are not cheap, especially if you want to record or stream video at high resolutions and frame rates. Even the best capture cards (open in new tab) can cost $200 or more. So, if you don't have that kind of cash, why not build your own for a fraction of that?

YuzikiHD has created an HDMI to USB 3.2 video capture board called the YuzukiLOHCC Pro (open in new tab) (discovered by Hackaday (open in new tab)). It may be hard to follow their instructions since buying one chip seems like a project in itself, but it's a cool project nonetheless.

The YuzukiLOHCC Pro has two HDMI ports for input/output and a USB Type-C port for connecting to a computer; if you've used the Elgato Game Capture HD 60 S (opens in new tab), it has a similar design. Like that card, it can stream and record video from game consoles, computers, and cameras at 1080p and 60 frames per second. It just doesn't cost $150.

According to the project's GitHub page, the chip can support HDMI up to 4K at 30Hz. Other resolutions are also supported. (Sorry, no 1440p).

Twitter has a video (opens in new tab) of YuzukiLOHCC PRO passing Splatoon 3 gameplay from Nintendo Switch to PC. The first thing you will notice in this video is that the latency is quite low, which is not surprising since it uses USB 3.2; if you are using USB 2.0, you will see a noticeable delay of at least a few seconds from source to output.

This DIY device works with any Windows, Mac, or Linux operating system. More importantly, it works with third-party video capture software such as OBS Studio and FFmpeg. Not bad for something that ultimately costs less than a slice of pizza.

How much cheaper: only $10. The only problem is that if you live outside of China, getting the MS2130 chip to make your own may be a problem. You can try looking on Taobao (opens in new tab) (requires free account to search) or try your luck at a local electronics store like this Twitter user (opens in new tab). The third option is to contact the manufacturer (opens in new tab) a (opens in new tab) cturer (opens in new tab) directly to special order the chip, but they probably don't intend to make this in large quantities. Chips could become more readily available in the future.
