Also make sure your digital SLR or whatever expensive camera you're using as a webcam doesn't have a 30m video limit, which some do. This is one of the most recommended pieces of advice on /r/videoediting (non-professional) for new streamers.
For most people, if you want better video quality for Zoom meetings or teaching Yoga online or similar, then a relatively recent smartphone camera + better lighting and microphone is more than sufficient.
Some cameras still turn off the video mode, it has been patched out in some nikon and Canon models as it's just a firmware limitation stemming from the same tax reason.
The video limit isn't related to recording but thermals. Often they just have an in built timer to turn off video at the point they tested the camera to be getting too hot.
