How to record live video using camcorder? I need to conduct a video conference using professional video cameras. I will be recording and streaming 1080p video [1]. To that end, I need to stream live video from a professional video camera to my PC. Here are the requirements:


The camera output is HDMI or SDI
The computer input is USB3
The delay between the time an event occurs and the moment it reaches the PC must be under 300ms.
The camera must show up as a webcam to the PC.
The PC will be running Windows or Linux.


Any ideas?

[1] I am aware of how much data is involved. Please assume that I have sufficient resources to do this.
