Magewell USB Capture HDMI 4K Plus

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

Whilst the video capture works fine, if you care about the audio and want it in sync with your video then this product is not going to meet your needs. Under both Windows and Linux, ffmpeg or OBS Studio, the AV sync is inconsistent at the start of capture, and then continually shifting during capture. Competitor products like the BlackMagic UltraStudio are much better for AV sync. Returned.

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

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.

For 459 Dollars You would think this card would do what it is advertised to do. No Matter What software I have tried I can not seem to get this card to record at 4K @ 30 FPS. The problem is not the recording software it is with the card as I can not even get any software to display the 4K single (without recording) at 30FPS. It seem the USB 3 speeds are not enough to send an entire 4k single across and not have any frame drops. I can get around 20 FPS at best, but that is not acceptable quality at all. Same goes for 1440P I cant get more than 25-28 FPS. I will say however it does send video at 1080P @ 60 FPS perfectly fine, but if thats all I wanted I could have gone with a much cheaper capture card. Something around $150-$180, not $459! Plus It does not come with any recording software and doesn't work with too many third party recording software's out there. It really only works with streaming software but your not going to be able to stream in 4k. I have tried OBS on Windows 10, with the Nvenc codec (which uses your graphics card for compressing the recording) so it easily can handle and record what ever single it is being presented with. The problem again lies with the card, it can not get a 4k signal at 30 FPS to the computer at all.
