The Magewell USB Capture SDI 4K Plus | 4K Video Capture Deviceconnects to your computer over a USB interface and lets you capture up to a 4K DCI resolution signal (4096 x 2160) with embedded audio via a 6G-SDI input. It also features a 6G-SDI loop-through for local monitoring, and 3.5mm audio input and output for capturing external audio and extracting embedded audio. It's compatible with Windows, Mac, Linux, and Chrome operating systems.

The card offers a variety of processing and other features, including resolution scaling and deinterlacing. It's capable of operating 24 hours a day, 7 days a week while displaying the status of the input via an LED indicator (idle, input signal locked, memory failed, or FPGA configuration).

Q: 5. The USB cable included with this device is very short. What type A to type C cables are compatible with this device. Up until now the only cable I can find that will allow the card to be recognized by my 2019 MacBook Pro is the cable that was included with the card. Even though other cards seem to match the required specifications the device does not power on and is not recognized by the computer.

A: I am sorry to say that Magewell advises to please use the included Magewell USB 3.0 cable, which is a custom accessory. Using any other similar cable might cause capture problems and even damage the capture device.

Q: 6. Could I use this for 4k going into a mac using quicktime app on computer?

A: Yes you can.

Q: 7. Will the USB port be fast enough to transmit 4k to the computer? I thought only Thunderbolt 3 could handle that.

A: Yes, this supports 4K through USB 3.0.

Q: 8. It says in the overview: Capture analog audio via 3.5mm unbalanced Line in jack. So if I have a PTZ Cam that has video only from it's SDI output that I can capture audio from an analog source simultaneously and this device will embed the audio with the captured video?

A: The answer is yes. you can capture video and audio from different source and it will combine during stream.

Q: 9. Is this compatible with Mac OS Big Sur11.2?

A: Unfortunately no. This item BH #MA32100 does support. Mac OS Big Sur11.2. Supported Operating Systems OS X 10.9 - 10.11 macOS 10.12

Q: 10. Apple computers (All) invert/flip or mirror video signals. Because of this when using FaceTime or Skype text appears backwards. This capture card states it supports flip/mirroring... is this feature available when using FaceTime or Skype?

A: According to Magewell the USB Capture Utility V3 allows for Mirror and Flip and they specifically reference Facetime for these functions. They do not reference Skype, but we believe it would work there as well.
