I just upgraded from Movie Studio Platinum 15 to Movie Studio Platinum 17 (Build 143) based on the promises of enhanced video playback through GPU acceleration. That much remains to be seen, since my RTX 2080 doesn't seem to be making a dent on 4K video playback.
More concerning, however, is that Apple Lossless Audio Codec (ALAC) formatted audio files no longer seem compatible with Movie Studio 17? Loading up a MS 15 project leads to errors locating ALAC files, and trying to import an ALAC file triggers a warning dialogue that the file is not supported.
I know for a fact the qt7plug.dll plugin (which appeared to decode ALAC files in Version 15) is installed, so I don't know why this isn't working.
System Specs:
Windows 10 Pro 64 bit
