I´m making dual screen videos using FHD videos. Resolution of the final footage is only 1520x428px, not 1920x1080px like it used to be.

Did I do something wrong or what?

Kinovea version is the latest 9.5. and screen resolution is 1920x1200.

You did nothing wrong, it has been like this for a while, I'm looking at fixing this for the next version.
