I’m using OBS which is a broadcasting software. I’ve got Elgato stream deck so I can just move around all the backgrounds in OBS.
I use OBS to record my screen capture video tutorials. That’s what I’m using these days. OBS is free. It’s open-source. It’s very powerful and effective and I prefer it to Camtasia because when I record my tutorials with OBS, as soon as I hit record, it’s done. I don’t even need to go through and edit it or anything.
That’s my basic broadcasting setup. If you want to learn, I have a video showing in detail about the whole process i.e. How to Use OBS for Recording Screen.
