USB HDMI Capture

This is a capture cable that can capture 1080p by utilizing the high-speed transfer of USB3.0. (It is USB2.0. 2020 8.1 added) This can be captured by windows and even macs without drivers, as video is transferred in the UVC codec and audio in the UAC codec.

Connect with the digital microscope

Easy to connect

The connection is simple.  All you have to do is connect the HDMI of the digital microscope to the main unit, and then connect the USB of the main unit to your Mac.  Power is supplied by USB, so it is not necessary.

All the functions of the digital microscope can be used via HDMI connection

I use this digital microscope.

This digital microscope has an HDMI output and a USB output with UVC codec, so you can connect it to your Mac via a standard USB cable to monitor the images of the microscope.

However, when the microscope is connected with a standard USB cable, it is possible to view images of the digital microscope, but functions such as displaying the menu and taking still and moving images of the microscope images cannot be used.

With an HDMI connection, there are no such limitations and all the features are available. So when I was looking for a reasonable HDMI capture, I found one that is selling for around $10 on Aliexpress and bought it.

Menus and still images can now be taken

The menu can now be displayed by connecting to HDMI. I don’t need to set it up for now, but I can do various settings.

It also allows you to take still images and videos.  When you take an image with a digital microscope, it is saved on the SD card.

This is the image saved on the SD card.

There are no delays that make it hard to watch, and it’s not a problem if you’re only investigating under a microscope.

Image quality is so-so

The image quality is sufficient for viewing digital microscope images.  I connected a Blu-ray player to try it out and looked at the image, but when I looked at it on a 24-inch PC monitor at 1080p, there was a slight color blur at the edges of the pattern.  If you don’t care about it, you won’t notice it.

However, the image quality is inferior (the edge is dull?) compared to the HDMI capture for game play that costs tens of thousands of yen.

But it was good shopping

I bought a cheap and quite nice capture cable.  I recommend it for those who want to easily monitor HDMI images on a computer without drivers.  It’s especially useful to be able to use it on a Mac.  It’s also convenient to be able to monitor the Blu-ray player’s video.
