USB Cameras
So I have a 4k USB-C camera and 2k USB-A camera. Nothing super high end, they’re still USB cameras.
Well, for a little bit I’ve been trying to record videos with my USB cameras. Things were lagging, and I wasn’t sure if it was not having a graphics card, so I pulled it from my son’s computer and threw one in. Didn’t notice much difference, but maybe.
So I was trying to setup a multi-camera setup in OBS. Quickly started running into issues with switching. I know using USB cameras are not ideal, so thought maybe that could be the problem. Sure enough, seems to be the issue.
Issue 1 - USB controllers have limited bandwidth
So it turns out all the USB ports in my computer are coming in from ONE controller 🤦🏽.
So using a 4k camera is going to be A LOT of bandwidth. A 4k camera and a 2k camera on the same controller? Good luck!!
Issue 2 - USB Cables
So USB is an electrical signal at the end of the day. After changing my desk to a sit/standing desk I got a bunch of USB extension cables. However, for the 4k camera I ended up using a USB-C to USB-A extension cable. So not only is the cable length increasing, but also the signal is being converted.
So I found a USB-C <> USB-C cable and and plugged directly into my USB-C cable in the computer. Let’s see.
Next Steps
I think if I want to be creative with multiple cameras is to get a USB controller.
Or I can grow up and get a real camera as my friend Alano recommends. But then I’ll need a elgato controller and it’s such a bottomless pit.
I like USB cameras because I can setup a portable studio anytime.
Permanently Deleting a Video Source
There was a source that was still appearing even after deleting it. Here’s the solution.
