HDMI Capture Card USB Video Capture Card Device USB 3.0 Grabber Game Capture Recording Box with HDMI Loop-Out Stream Full HD 1080P60 Support Windows,Mac OS and Linus System

I've been using USB and USB 3 capture cards for at least 5 years now. For mobile and on-the-set setups these devices are awesome. This USB 3 capture card DOES support multiple cards connected to a single computer. I have two connected (1080P 60fps) at all times and they work great. Most of the expensive cards will not run two at the same time. I have a third but it's connected to a second computer (haven't tried three on one pc). Also verified it to work seamlessly on the MAC with no driver installation as advertised running Wirecast. These cards do get a little warm, as expected, so keep them in an open area to get good air flow (don't lay stuff on top of it) or you could possibly cause it to lock up. Awesome product I run 1-2 hour broadcast each week and they are very reliable.

I use this for work, to capture the screens of command-line-based computers, and it works pretty well, especially for the price. It plays nice with Linux too (using Ubuntu 18.04 on the laptop it's plugged into, no additional software necessary for Ubuntu to register it as a camera device)My only complaints are:1. It occasionally seems to glitch on the passthrough (usually after my laptop and the other systems have been off or in standby for a while), which necessitates unplugging the unit entirely (USB and both HDMI in and out) and reconnecting,2. Also occasionally glitches on device availability (again, usually after my laptop has been off or in standby) so I don't see it as a camera device on my laptop; a quick unplug/replug of USB seems to resolve it,3. Text and other high-contrast display elements seem a bit off; this is likely a result of the capture device being optimized for motion, so static elements get a little weird. I suspect this isn't fixable short of throwing more expensive hardware at it (and the point of getting this device in particular was because it was cheap)The screenshot shows #3; all text elements are supposed to be "white" (you know, that dull grayish white of a console terminal) but somehow all the box drawing characters show up with a blue hue, and the text has some rainbow aliasing around it. Still perfectly legible and it works great for my purposes so I'm not docking it for that.The glitching is problematic, but I'm sure my environment isn't helping matters much either (using a KVM output as input probably isn't the greatest idea, and the device already gets plugged/unplugged a lot as I take my laptop from the workstation, and both the input devices and my laptop go into and out of standby regularly) so I'm only docking one star for that.TL;DR: not perfect, but unless you need perfection and are willing to spend $$$ on it, this capture dongle is probably your best bet.

This capture card worked great for the first 4 times that I used it. I was using it to allow my Panasonic GH5 to be sued as a Web cam for my Zoom presentations. Using the output from my GH5 as a Web cam made a HUGE improvement in quality of my broadcast. Worked beautifully once I changed the settings in Zoom to 1) 16x9 (Widescreen); and 2) Enable HD. Actually there was one other issue, which was the video being out of sync with the audio. I fixed this by using a shotgun mic on my GH5 as the audio source (which automatically comes in on the same HDMI output from the camera). You could also fix that issue using something like OBS (Open Broadcaster Software) and adding in an offest on the audio channel.So that's the good news. The bad news is that on the 5th use, the card failed to power up. Normally it's pretty much plug and play. Once it's connected the activity LEDs light up. On my 5th time, no LEDs. I then routed the output from my camera directly into a monitor and it was working just fine. I tried all kinds of combinations of cables and ports (on my Mac), but it was just dead. (And just to note, yes, this works on a Mac. I saw a review that said it didn't work, but that's not accurate. Works just fine on Mac.... when it works.)I gave it 4 stars for the features and for the overall quality coming out of it. But had to give it 1 star overall due to the poor reliability. I'm also 2 weeks past the Amazon return date, so we'll see if I 'm able to get a replacement. If I do I'll update this review.

I bought my first one of these and just couldn't get it to work on my main laptop. All I was getting was either a blank window, or a message saying the camera wasn't connected. But it worked fine on a duplicate laptop and even on an older one. Everything we tried wouldn't work. Seller sent a replacement and had the same issue.It turned out to be a permission problem with my webcam on the laptop. Some apps will request permission to access to access my camera, and I always say no. But once I changed my settings to allow apps to control the webcam, not only did the webcam start working in XSplit, but also this device works as well.It seems to deliver a nice quality picture for the 2 events that I have used it on.

I'm very happy with the product! It's easy to figure out, and the capture quality is great! I got it for my wife to instruct her Zumba classes via live stream using a Sony digital camcorder with clean HDMI output. The sound quality is best if you use an external mic plugged into the capture box.

As we all started working from home and started using Zoom, the webcam on my aging surface pro 3 just wouldn't cut it. I bought this to connect my mirrorless Sony A7R3 as a webcam. I went for this one as oppose to the brand name one because everything was out of stock or hiked up to 2-3 times the price at the time.After half a year and hundreds of Zoom meetings, this unit has really served me well. Never had any issues with it, gave me crisp and clear 1080p feed.

Don't waste your time with this one. I returned it and got a different unit.
