Really new in Movie Studio 13 is the ability to cut 4K. For this also runs liquid sets the software to proxy files, so that a fairly liquid preview is possible. Works (optional) automatically when importing files.
Initially rushed at me from the Stabilizer. But was probably because of my computer. The Stabilizer has been greatly improved in version 13. The Stabilizer of the previous versions were rather useless. The "new" Stabilizer does not need to hide behind expensive plug-ins like "proDAD Mercalli".
Export in 4K goes with almost any setting. It is an error message. And although the appropriate templates in 4K are present in some codecs. What does the 4K Export in the setting "MainConcept AVC / AAC". That's MP4 and can be adapted to the needs. Unless Entwarung.
The only thing that still bothers me is that there is no preview images of video files in Media Explorer.
