AV.io 4K – Grab and Go USB Video Capture for HD 1080p 60 fps and UHD 4K 30 fps

One of the best products I've ever purchased. It requires no configuration, and just works -- every time. I've used this for more than a dozen different projects, and it's become my go-to device for capturing HDMI video for training, presentations, webinars, etc.

What a time saver. I have it hooked up to a Sony X3000 and a Dell XPS 12 and It can record for up to 10 hours without changing a battery or SD Card, The Dell doesn't even reach the minimum specs (i5 core M) and it records perfectly.

If you have a MacBook Pro and a PS4 Pro, don’t bother getting this, your PC won’t be able to take it. I tried every option available on OBS and it would constantly skip frames. You would think that since this device does most of the processing work, that this would allow the PC to work effortlessly, but no. You need a good computer for any capture card to work and it’s taken me a few tries to finally figure this out. Check specifications before buying.

My plan was to connect my Xbox One X to an HDMI splitter, then connect this device to the splitter to capture to my MacBook Pro then stream via OBS. I wanted to connect my LG C7 to the splitter for 4K HDR video. I tried two different methods to split the signal and both methods resulted in no HDR signal to my TV. I contacted Epiphan support, told them about my setup and what I was attempting to do, and they told me there's no splitter solution out there that I could connect this device to that would also output 4K HDR to my LG C7.Aside from not working with my setup, it's a great product. Epiphan support was easy to get in touch with, friendly, and knowledgeable and if something comes out that fits my needs, I'd totally go with them.

I was very reluctant to spend $500 on this considering there were cheaper alternatives. However, the “plug and play” feature really appealed to me, so I decided to give it a try. It worked as advertised. It’s a little bigger than I imagined, but thing feels high quality. I have it connected to my Sony AX-53 4K camcorder. The image quality is beautiful and there is no lag when I’m live-streaming on my 2017 MacBook Pro. Exactly what I was looking for.If I get a second camcorder, I’m going with the 1080p version, however, since my streaming software only outputs at 1080p.

This is great, but not for me (returned it). I was hoping to use it as a mirrored display and that did work, however it forced my 144hz monitor to 30fps.My plan was to run my monitor at 2k 144hz GSYNC and capture 2k @ 60fps, however this captures 2k @ 30fps (which is fine) however it ended up capping my monitor at 30hz. Had it not done this, it would have made the perfect capture device for someone wanting to keep 144hz GSYNC and also stream.

This review is for Epiphan and not the Seller Go Smart. Ordered this product for my son. It arrived in a timely fashion and appeared to be in a new manufactured sealed package with all of the parts, thank you Go Smart. From there the experience went down hill when he tried to call Epiphan tech support for help. He tried to call multiple times without getting through or getting any real help. They finally offered a solution which was a third party software download. When that happened, it still didn't work. Very disappointed and would like to get our money back. Product is still new.

Unboxed the AV.io 4k. Attached the cables to my camera and computer. The camera was visible and provided a great image. Just make sure the camera you are planning to use can produce clean HDMI output
