Sony Vegas is a professional non-linear editing system (NLE) originally published by Sonic Foundry, now owned and run by Sony Creative Software. Originally developed as an audio editor, it eventually developed into an NLE for video and audio from version 2.0. Vegas features real-time multitrack video and audio editing on unlimited tracks, resolution-independent video sequencing, complex effects and compositing tools, 24-bit/192 kHz audio support, VST and DirectX plug-in effect support, and Dolby Digital surround sound mixing. It's designed for Microsoft Windows XP, Vista and 7. In April 2007, Sony along with AMD jointly demonstrated a 64-bit version of Vegas running on 64-bit Vista.
The consumer level Sony Vegas Movie Studio version (formerly titled VideoFactory and Screenblast) shares the same interface and underlying code base as the professional Vegas version, but does not include professional features such as advanced compositing tools and 24p editing support, nor does it contain the capability to burn DVDs or Blu-Ray Discs (without accompanying software DVD Architect Studio). In previous releases, the video editing portion of the professional suite could be purchased separately from Sony's DVD and Blu-ray Disc authoring software, DVD Architect Pro (previously called DVD Architect; DVD Architect Studio is the consumer version), then a package called 'Vegas + DVD' became available while Vegas 7 was out. Since the release of Vegas Pro 8.0, both DVD Architect Studio Pro 4.5, Vegas Pro 8.0, as well as Boris FX LTD and Magic Bullet Movie Looks HD are all bundled together and may not be purchased individually.
