Should get an HDMI to USB-C thing so i can use the loved one's DSLR as a webcam.

what's a good one?

@davidgerard I got a Genki Shadowcast that I don’t hate, but you can get decent capture dongles on eBay for like 10 bucks
@davidgerard Anything with a MS2130 chipset - brand doesn't matter, they're all basically the same inside.
@dusk what are some examples? I'm looking for stuff to add to an Amazon wishlist.

I got an Elgato Cam Link 4K back at the start of the pandemic. I also have (https://www.amazon.com/Capture-Streaming-Conference-Teaching-Broadcasting/dp/B0C9STZMDR/ref=cm_cr_srp_d_product_top?ie=UTF8) that seems to work as well for 1080p capture.

@davidgerard Literally just search for "MS2130" - https://www.amazon.com/dp/B0CMT5SNFQ is one example but anything with the same chipset will be just as good.

@davidgerard Be certain the camera can do that. Not all can.

@davidgerard I've got an ezcap brand one that has worked pretty well: no special software needed as it presents as a standard USB video class device, and it has HDMI passthrough. It has even worked on USB 2.0 mode, offering MJPEG modes rather than raw YUV2. The only thing I don't like is the non-standard USB-A to USB-A cable it uses.

The model I've got is a bit old, but this seems to be the equivalent current model: https://www.ezcap.com/ezcap321. It seems the best way to get one is to pick one of the sellers on AliExpress at random.

I've also used some of the cheap dongles, which tend to work but have a lower quality output (e.g. they might only do MJPEG). That might be for recording from a camera, where that compression gives acceptable results.

@davidgerard I use cascable pro and usb, but that’s on a Mac.

It’s great using a dslr as a web cam
