Does not work with all HDMI sources

By Charles
Rated 2 out of 5
Date: 2026-05-17

I purchased the Magewell USB Capture HDMI 4K Pro expecting to use it for capturing video and audio from all my HDMI sources. When attempting to capture HDMI from a 2011 era camcorder, the audio track was a constant white noise with embedded clicks, like a helicopter or motorboat. I contacted Magewell support and after much testing, they told me the audio was probably encoded using Dolby and they do not support Dolby audio. This limitation is not documented in any of Magewell's documentation. This device is far too expensive not to support common formats like Dolby.

Drops frames

Well built and I desperately wanted to like it, but it drops too many frames. I sent test recordings to a video editor from this and two other, much cheaper, devices. He didn't know which device was used on which recordings. Recordings on this were worse than on others.

Will the Magewell USB Capture HDMI 4K Pro work with an iPad Pro M2... going from camera HDMI to iPad as monitor?
Asked by: Jeffrey
Yes, if you use an iPad app, like Orion, with the Magewell USB Capture HDMI 4K Pro, you could turn the iPad into a video display. Please note that you would also require a USB-C to USB-A adapter such as the Pearstone USB 3.2 Gen 1 Type-A Female to USB Type-C Male Adapter (B&H # PEAAFCM). For your convenience, here's a link to the Orion app: https://bhpho.to/4e62t5d.

Will a USB4 or Thunderbolt 3/4 generally suffice for the 20 MB/s 3.2 gen 2 required?

USB4 and Thunderbolt 4 have a maximum speed of 40 Gbps, so either would be suitable for use with the Magewell USB Capture HDMI 4K Pro.
