I create a lot of video tutorials of people standing in front of a green screen. It is often difficult to source good quality background replacements of Offices or business locations etc. Could you please start adding more varied background replacement images?
There's a lot of this kind of material available online or you can use your own photos. In fairness to TechSmith, there's no way they can anticipate everyone's needs for backgrounds and similar graphics.
Frankly, I'd rather see them concentrate on improving the functionality of the product and expanding features, rather than stock image libraries.
