Blackmagic Design DeckLink 4K Extreme 12G Capture Card (BMD-BDLKHDEXTR4K12G)

Has worked perfectly since I purchased it almost 4 years ago. Excellent video quality and no compatibility issues whatsoever.

The Most Simple and Beneficial HDMI output I've owned. When I first learned about Blackmagic I was sold. My church uses a ton of solutions from Blackmagic and seeing what it did for the lower cost of some other solutions i was sold. The reliablity of blackmagic products is wonderful. Prior ro using this product I used Matrox products. I'm a Mac user now but once as a video beginer I was a windows user, primarly because its what I used for work. I used a Matrox system on that and it was ok. Then When I moved to Mac I got a more current Matrox MX2 mini, absolutly horrible. I paid $449.00 for that thing and it would constantly glitch out. When I bought that thing took Matrox 6 months to even have software for what I had then premiere pro CS5. I always kept up with the software too matching the OS I had and editing software. Never did it work like it was suppose to, maybe it was good for windows but a $449.00 paper weight when using on a Mac with Premiere pro CS5. Then one day that Matrox just quit working. So I was skeptical of the low price on the DeckLink Mini Monitor. It just works! I emailed the company told them the OS i used and that I was using CS6. They pointed me to the newest driver 10.6.2. This version works with OS 10.11 running Premiere Pro CS6. Although the software mentions CC 2014 and newer, it does work with CS6!!! So to my delight it does exactly what I need. Hands down 1000 times better than Matrox MX02 mini ever thought of! Its just an output only but that's all I need. I need it for previewing what my content will look like on a HDTV monitor. Because a TV has colors different than a computer monitor. You need to output to an actual TV when editing to get the color closer to perfect.

Unlike the Black Magic intensity shuttle, this little PCI card just works... all the time... no problems.With the portable versions of the same interface there are frequent connection issues. Sources get lost, it misidentifies them in OBS... etc.This little guy just works. It's been crucial for me for running my DSLR as a camera for teaching my students during COVID. I'm also considering building a computer with the multi-input version for my church to do live-streams.Yeah, it's not the best overall value, and you can find cheaper solutions. But you're paying for Black Magic and as I tell my children: Don't buy cheap tools that break -- buy the right tool once.WOULD BUY AGAIN

I like this card because it works for capturing hd video from a camera. It can capture it so you can see it in real time on your computer, play it, and record it. Aside from this, it doesn't do much more. What I mean is you don't get support for other things you might want to do.I wanted to use this with Skype, but after trying for a few hours, I gave up on it. You can't use it with Skype unless Skype natively recognizes the video. I used an hd sdi camera (with resolution of 1080p), because the black magic card has input for both hdmi and sdi. For my camera, Skype would not natively recognize the video, except when I use a third party program like manycam to connect the video to Skype. But to unlock manycam's hd features, you need to buy the pro version which costs $50. In addition, manycam's "hd" viewing video is very grainy, so even when I see it in Skype, it's very grainy as well, so a degradation in picture quality, although it does work. (as a side note, I'm thinking that maybe Skype doesn't support hd too well anyways because of internet bandwidth and not hardware, but this may or may not be a factor).What I like about this card is that it does recognize an hd video signal as long as it matches the configuration of the card's resolution and frame rate. For example, 1080p 30 fps. It can go from 1080p to 720p at varying frame rates, ntsc or pal. I emailed Black magic about compatible cameras and they responded:"We unfortunately do not have the compatibility listed or categorized by camera. Instead it is basically organized by supported resolutions and frame rates.Your camera basically has to support one of the following resolutions and frame rates......720p50, 720p59.94, 720p60, 1080PsF23.98, 1080p23.98, 1080PsF24, 1080p24, 1080PsF25, 1080p25, 1080PsF29.97, 1080p29.97, 1080PsF30, 1080p30, 1080i50, 1080i59.94 and 1080i60."note: I'm not absolutely sure if this list is completely inclusive, but this is the list given to me in email for sure.If your resolution or frame rate is not listed, maybe it could still work but it's a hit and miss. Notice the resolution quoted to me is all hd and not sd. What I'm saying is just because your camera is not on the list doesn't mean it absolutely will not work, I tried a camcorder and it wouldn't work but all of a sudden it did (I don't know why), but the camcorder was built for uploading through hdmi and not streaming so it was a waste of money. The camcorder's resolution and frame rate was 720p at 29 fps and somehow the setting for the capture card was set at 1080i at 59.94 fps and an image came up for uploading from camcorder to computer (no other setting would work). My camcorder was only built for uploading and not streaming so it was a waste of time and money. Don't know how camcorder image for uploading from camcorder to computer came up, or what this means, but a fluke of nature, I don't know.So this capture card comes with a basic play and record software, but whether you want to use other software, it's totally up to you. There is no support for making this software work with Skype, 3rd party software and such. Or if there is support for it, you have to research it on your own. So therefore anything you do outside of the card and accompanying software is totally up to you. So it's not like you plug in this card, and you can plug and play with Skype and stuff like that. You have to research it. You have to make it work.This is why I gave it 4 stars, because it captures my hd video, but outside of that, it doesn't appear to me to do much more.

The card works great with it's own capture software. So far cannot get Cyberlink PowerDirector to capture through it, but we'll keep trying. Had sync issues no matter what we tweaked, but come to find out all we needed to do was reset the sound card and poof, all was well.. ...
