INOGENI 4K2USB3 Overview

  • 1Description

The Inogeni USB 3.0 4K HDMI Video Capture Card allows you to capture uncompressed video with audio from your camera's HDMI output on your PC for recording, editing, videoconferencing, and streaming applications. No driver installation is necessary and it will work on all motherboard and USB 3.0 chipsets. It features a HDMI input and a USB 3.0 output. Compact in size and powered directly from a USB 3.0 port, the converter is a practical and easy-to-use USB 3.0 capture solution. It is compatible with Windows, Mac OSX, Linux, and Android operating systems, and is UVC-compliant, so it will work with all DirectShow compatible software. This capture card is backward compatible with USB 2.0 devices. However, due to bandwidth restrictions, the card will only be able to operate at resolutions below 1080p.

The converter supports 4K resolutions up to 30 fps, and 1080p resolutions up to 60 fps as well as most computer graphic formats. All SD and HD resolution signals are converted to 4:2:2 8-bit color space over USB 3.0 while all UHD resolution signals are converted to 4:2:0 8-bit. The embedded audio in the HDMI signal is extracted and output as two-channel LPCM. A USB 3.0 cable comes included.

    INOGENI 4K2USB3 Reviews

    USB 3.0 4K HDMI Video Capture Card is rated 4.6 out of 5 by 28.
    Rated 5 out of 5 by from Sophisticated piece of equipment I own a Sony A7R II and wanted to record 4K without the stupid 30-minute time limit. To the options were basically limited to recording with the Atomos Shogun (too expensive!), BlackMagic Mini Converter (FullHD only, no 4K) or the INOGENI. This device took *a lot* of set-up time. It only seems as simple as plugging in a microHDMI-HDMI cable to your camera and then USB to the computer. In actual fact, it's not so simple. First, you need to make sure your USB drivers on the computer are up to date. And of course it has to be USB 3.0 to be fast enough to record. Also, your recording media has to be fast - you need either an SSD or a RAM Disk. And be prepared for hundreds of gigabytes of stuff, as well as atrocious post encoding times, because INOGENI does not come with hardware h.264 encoding. Next, you need some software for capture. I recommend just using ffmpeg - personally I've not had much luck with VLC and other tools, no idea why. ffmpeg is for techies, but it gives you greatest control over what you are getting. Realtime encoding of 4K to h.264, even with NVENC support, was a complete failure: the machine is not fast enough. NVENC is good for post-hoc transcoding (it gives about 2x performance improvement, could be better) but even it is not fast enough for realtime encoding of 4K videos. Sorry about this. Also... if you open up your uncompressed 4K video, you might see garbled video with missing frames, and recoil in disgust. Don't worry. It's just that the video renderer is unable to process so much data (I have a huge graphics card in my laptop and it doesn't help, I'm afraid). So to figure out whether the footage is OK, I recommend you record half a minute of video with motion (e.g., just zoom or turn the camera smoothly), use ffmpeg to downscale to low-quality 720p and look at what you're getting. The image should be fine. So to sum up, using this device in 4K was a bit of a technical affair for me. Using it for 1080p is of course a no-brainer, but then again, if you need 1080p only just go with Black Magic Mini, it will do the trick (also it's thunderbolt, feels safer somehow). But if you absolutely need 4K (e.g., you own A7RII or A7S or GH4) then this is the device for you. Just be prepared for some work beforehand. Just in case anyone needs it, here is the command I used for capturing video on Windows: ffmpeg -f dshow -rtbufsize 1500M -video_size 3840x2160 -i video=2318-INOGENI 4K2USB3:audio=Digital Audio Interface (2318-INOGENI 4K2USB3) -q 1 c:\4k.avi P.S.: INOGENI's support has been excellent in answering my questions.

    Rated 5 out of 5 by from Better for Streaming Video Over the last two years I've upgraded to streaming HD video and it has not been painless. For everyday streaming, or mission critical applications where you need a backup solution, Inogeni into my PC laptop is totally solid. Unlike Magewell it has no audio sync problems, and my encoding software (Wirecast and/or FMLE) recognizes the capture device immediately. CPU load in my configuration is 50% and the setup runs all day long without complaint or overheating.

    Rated 5 out of 5 by from One HDMI converter to rule them all... The 4K2USB3 adapter is fantastic. Super small, rugged, simple to use, great quality captures. Pros: I am an using a full-spectrum-modified Sony A7s for astrophotography, which produces uncompressed 4:2:2 UHD 4K output via HDMI. Connecting the 4K2USB3 adapter to a USB3 port on my laptop allows me to use any webcam -compatible software package to achieve critical focus and to capture full resolution images for subsequent post-processing (alignment, stacking, etc). Free products like VLC Viewer work fine to display images real-time. But even nicer, Astro-specific webcam packages such as SharpCap and MetaGuide work perfectly also, enabling functionality like crosshair overlays or telescope guiding. Cons: This unit initially failed to enumerate properly when plugged into an Asus UX32 laptop. So, I unsuccessfully tried it on my office PC, which also happens to use an Asus mobo. The failure mode was odd, since the supplied diagnostic utility could report the firmware version in the 4K2USB device, but the USB-side LED on the unit did not illuminate and it did not stream video. I downloaded and installed the latest USB drivers from Asus, but the problem remained. I emailed a problem report to the factory. They logged onto my PC using TeamViewer, deleted the USB3 root device driver, rescanned the bus to re-install the drivers and subsequently the unit enumerated properly and worked perfectly. Subsequently, I repeated the process on my laptop and it too works fine now.

    Rated 5 out of 5 by from Awesome, and customer service is great Works just as described. I had trouble with video capture on the USB side, and they were probably the best company I've ever dealt with. I talked to actual engineers who actually knew what they were talking about and wanted to help me solve my problem. I can't say enough good things.

    Rated 5 out of 5 by from Great Converter, Just works How I use this: I use two of these to bring a GoPro video stream and a computer output stream into a single Lenovo t440p laptop. Things that are great about the product: It just works. I plug in an HDMI stream and plug USB 3.0 into my laptop and then set the device to view and I get a near real time HD stream into the computer. I plugged a second one in at it work at the same time without delay. Easy to use, good construction. I couldn't ask for much more. I replaced a BlackMagic Design Shuttle with these units since the BlackMagic USB 3.0 only work with certain USB3.0 controller. Things that aren't so great: It is expensive, but honestly it is worth the money since it really is plug and play. Overall, this is a great product that does as intended. Very happy with this.

    Rated 5 out of 5 by from Image looks great This project is truly a plug & play unit that just works. I plug it into my usb 3 & opened up my sony vegas 13 capturing window & there was my image ready to be captured.

    Rated 5 out of 5 by from Great Service. Great Product I needed a converter piece for a simulcast the next day, and B&H helped by getting it to me in time. The staff is knowledgeable and knew exactly what I needed only by me describing what I needed to do. Also the converter worked great! So easy to use.
