Screencast Resolution Setting

I think you are right Peggy, the best way to achieve this with Storyline screen record is to ensure you set your project to 1920x1080. Unless your project is huge, it shouldnt add too much in terms of final size.

Another option is to use some other software specifically for screen recording. These allow you to zoom in on various parts of the screen at key points. Some of the apps even allow you to set a final output resolution, and the software will automatically ensure everything fits and is scaled for perfect view.
