That was three Windows versions and 7 years ago. In 2007 the first mainstream Windows 64-bit OS, Windows Vista, was introduced. The first 64-bit Intel Xeon processor was introduce 10 years ago in 2004. You really need a 4-Core CPU with 8GB of memory to edit today’s video formats and that requires a 64-bit OS. That rules out using a 32-bit OS to take advantage of all of the processing power a multi-core CPU can give. A properly configured computer should have 1GB per core minimum and 2GB per core recommended. Newer HD video formats require multi-core CPU’s and multi-core CPU’s need more memory than 32-bit OS’s can address.So one reason is to be able to address more memory for larger video formats and memory hungry video FX 32-bit OS’s only allows 2GB of memory maximum per program and when you get into formats like 4K that isn’t going to be enough memory for editing and processing and rendering video.“Also if you can offer any information as to why they moved away from 32-bit, if in fact they have, I’d be interested to know that as well.” I can confirm that there is no 32-bit version of Vegas Pro 13.0 or Vegas Pro 12.0 nor will there ever be. “I’m guessing, from the inability to find any information on the subject, Sony Vegas 13 is not available in 32-bit? Can someone confirm or deny this?”
