We have some threads this month discussing the performance of UVC HDMI-USB3 Vide Capture stics/dongles or devices. If technical specs are available, sadly often deficient, they may manage 422 chroma subsampling, but limited to 8-bit "Deep color" (4KVC00) or "YUY2" (ms2130) 1. To repeate the illustrative article 8-Bit vs 10-Bit Video Color Explained (millions/banding vs billion shades): https://fujifilm-x.com/en-us/series/the-filmmakers-handbook/8-bit-or-10-bit-... 2. In a couple of learn.microsoft articles, 10- and 16-bit YUV Video Formats are recommended for capturing, processing, and displaying video, while 8-bit YUV color formats that are recommended for video rendering. To extract and learn the most relevant YUV formats in this context from the table https://learn.microsoft.com/en-us/windows/win32/medfound/10-bit-and-16-bit-y... YUY2 4:2:2 Packed 8 bits pr channel Y210 4:2:2 Packed 10 NV12 4:2:0 Planar 8 P010 4:2:0 Planar 10 3. So I found an interesting discussion on the Digital Photography Review forum: Cheapest (and decent) way to record 10 bits HDMI on Windows? https://www.dpreview.com/forums/thread/4562209 Extract here an interesting section from the first reply of Mar 19, 2021: It almost looks like 10-bit may not be part of the UVC specs unless the device does hardware H.264 or HEVC decoding, there are no 10-bit color formats that appear in https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/driver... such as p010, and I would expect that if the UVC spec supported p010 video it would have appeared in the Linux kernel by now. If someone can confirm this is the case also today, we don't need to search for cheap or inexpensive HDMI-USB3 Video capture stick/dongles with 10-bit 422 output support. Down In the same thread also some high-priced UVC compliant devices are mentioned, but they tend to support 10-bit on HDMI input and so downscale it to 8-bit on USB3 output.
