The recording performance of Screenium 3 is astonishing and I haven’t encountered any problem so far. The video editor’s usability could be slightly enhanced but overall Screenium 3 has impressed me. No matter which applications were running, Screenium recorded continuously at a high frame rate without dropping any frames. Since I create video tutorials for a living, the release of Screenium 3 has been terrific news for me. Especially since version 3.1 makes it possible to record iPhone, iPad, AND Apple TV 4! That’s a huge surprise. One importing hint: You have to install a free plugin called SoundFlower if you want to record system audio. That’s just the same as with other recording tools I know.
