Is using a screen capture software expensive or difficult to do? In 2023, why would someone not use one instead of hand holding a phone to record so that every time they look away, the phone bounces and makes whatever they are showing on the screen impossible to read?

It’s a bit frustrating for how much time is spent showing a screen.

However, making the same video with screen capture would require a good amount of editing to also show the toothbrush. Here everything seems to be in one take. I don’t blame him; as easy as it is now, editing is still time consuming.
