Sony Vegas is a professional non-linear editing system originally published by Sonic Foundry, now owned and run by Sony Creative Software. 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.

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.

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, while 24p editing support is only official with Sony Vegas Pro. Previously, Vegas could be purchased separately from Sony's DVD and Blu-ray Disc authoring suite, DVD Architect Pro (previously called DVD Architect; DVD Architect Studio is the consumer version), as a package called 'Vegas + DVD'. With 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 bundled together and may not be purchased individually.
