Maybe someone can help me with this as I've been "stung" before because of Magix's naming conventions for their video editors. I have - and use - Movie Studio 16 Platinum which seems to me to be the reincarnation of VEGAS. I also bought Movie Studio 18 and 22 at various times (good deals) but they seem to be a dumbed down UI and application, so I don't use them (and have uninstalled them apart from the extra plug-ins they came with).
Which "family" is Movie Studio 24 a member of? What about VEGAS Pro Edit 21?
