Good point! For my use case (on a different brand, Sony) I’m fine with the lowered resolution since I just use it for video conferencing, in which case the raw resolution is limited anyway. But for users who need higher resolution, using an HDMI capture card might be better for a one time fee rather than a subscription.

Is mechanical shutter necessary for max bit depth on your camera? It isn’t on mine (Sony), but bit depth reduces to 12 bit if you max out the framerate. You might still be able to get full 14 bit RAWs if you drop the framerate.

You can do this on Linux using gphoto2, ffmpeg, and v4l2loopback. You probably won’t get full resolution but the quality will still be good enough for video conferencing. See here for a guide.
