Magix has put out a Short on YouTube in German showing removing one of two skiers from a video. How was this done? My German is next to nothing and the video doesn't show much.
It's definitely Hide. I recognise the tool bar in use.
Useful for short clips shot at the correct angle to a usable background and a subject that is separated from other interacting objects. The faster the frame rate in my experience the better the result but the slower the processing goes. They make it look so easy.
