I have been using the magewell HD and 4k with a 4K Marshall camera successfully, when set to output HD resolution.
Now I’m testing the videoGrabber to capture 4k but the grabber sets itself to 2560x1440 even though
**[notice ] Device: 0: USB Capture SDI 4K+ #2** **[notice ] 0: USB Capture SDI 4K+ #2** **[warning] ofAvFoundationGrabber: requested width and height aren't supported. Setting capture size to closest match: 2560 by 1440**
Does anyone have experience with capturing 4K over this USB device?
