I am considering purchasing one of these:
It claims to be able to capture "uncompressed video", but in the list of output formats in the document above (page 67), it lists "MJPEG,YUY2". I know MJPEG is a compressed format, but I'm less certain about YUY2.
The source I'm considering is a Surface Pro 7 which outputs HDMI via a USB-C port. I am under the impression that the Surface is likely to output sRGB by default. My reading of the Wikipedia article on YUV leads me to believe that if the capture device receives an HDMI signal using the sRGB color space, and outputs a stream using the YUY2 color space, information must be lost (some discussion here seems to support this theory).
Is there any sense in which this device can claim to support "uncompressed" video or is that misleading?
