Capturing 4K with OBS and Zooming in During Live Stream
If you are live streaming you are more than likely streaming in high definition and that makes a lot of sense. If you are streaming in 4K you are going to need a higher bandwidth and you would also hope that your audience are going to take advantage of that.
So why capture in 4K? Well that allows you to zoom in without having to zoom on the camera and not lose any resolution on your output. You should be able to zoom in 200% without noticing. This is great if you want to have a static camera, start with a wide angle and then zoom in. I find this useful for when there are multiple presenters and they are different heights. I set it for the tallest and can then make other shots for the other presenters. It is also useful if you have an interview or panel and can set shots to pan.
Here I am showing you OBS but if you want to see how this works using Wirecast then check out this video, • Wirecast and the 4K Advantage - Zoom in on... , by the way, Wirecast does a much nicer job of the zooming.
