Magewell USB Capture HDMI 4K Plus Device

This is fantastic equipment to use. Even the beginners can just plug in & play. Very easy to use and scaler built in.

Works great but how can the manufacturers justify such a high price?

I'm running Fedora 29 on a Ryzen 7 with an ATI Vega 64. Because Wayland's video screen capture abilities are terrible, I wanted to capture the HDMI output of my computer and feed it back the USB port for screen recording. This device worked flawlessly right out of the box. I knew that USB had bandwidth limitations, so while my screen is 4K, I told obs (Open Broadcaster Software) to use V4L and the device showed up immediately with no fiddling required. All the different capture modes showed up as well in the resolution selection. So I was able to get 1080p at 30fps with full color and it just worked. Few hardware manufacturers are willing to put in the attention to detail in their software so that specialized driver tweaks are not needed to account for ways in which their specific piece of hardware fails to follow standards specifications. Magewell deserves huge props for not being a manufacturer who is willing to do the work. This is how all hardware should be.

Absolutely terrible waste of money, stopped working after 1 month after purchase. Dont buy

Works like a charm (I'm hooking up a Canon XC15 to a Macbook Pro Touch). It's literally just plug and play. One side plugs into the camera's HDMI output, the other into the computer (through an Apple USB-C to USB-A adapter). You could probably eliminate the adapter with a USB-A to USB-C cable. Shows up as a webcam to the apps running on the mac. On the down side :(1) There's a fan (the circle with the Magewell logo on it is the fan vent). It's noisy enough that I can hear it. I put the thing in a box, but I'd much rather have a humongo heat sink and no fan. (2) There's a noticeable lag between real time and the output. I run my sound through the camera, so there's no audio/video synchronization problems, but this could be problematic if you were matching sound from the computer with the video. I ran their app and set the output resolution to 720P (the input from the camera is 4K), and that's helped a little, but hasn't eliminated the problem.
