Sony Vegas Pro

Sony Vegas Pro is a video editing software package for non-linear editing systems (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. Up to version 10, Vegas Pro runs on Microsoft Windows XP (32-bit only), Vista and 7 (both 32-bit and 64-bit editions). Version 11 dropped support for Windows XP, and

Features

Vegas does not require any specialized hardware to run properly, allowing it to operate on almost any standard Windows computer across a broad range of hardware.
In areas of compositing and motion graphics Vegas provides a broad tool set including 3D track motion compositing with control over z-depth, and spatial arrangement of visual planes including plane intersection. Unfortunately keyframing of simple 2D motion lacks bezier adjustments and multiple keyframed smooth motion is marred by slowdowns or hesitations at each keyframe.
Much of the visual effects processing in Vegas follows an audio-like paradigm. Effects can be applied at any stage of the visual signal flow — event level, track level and output level effects, much like reverb, delay and flange audio effects are applied in a digital audio system, like Pro Tools, Cubase or Sonar. Master output effects can also be controlled and manipulated over time by the use of Master Bus track automation envelopes.
As of version 8.0, Vegas reads MJPEG AVIs (usually from "video" setting on digital still cameras). (With prior versions of the software, installing an MJPEG codec sometimes fixed the problem.) Third-party codecs are supported but it can be difficult to see which codec is being used to play back an AVI. Some of Vegas's codecs are 'native' or built-in.
One major omission of Vegas is that, although it started life as an Audio Multitrack NLE, it has no MIDI capability at all. (Apart from control-desk and synchronisation.) This restricts its use for Audio production, focusing the product on the post-production, Video NLE market only.
Vegas features integration with 24p DV. It is also one of the few NLEs which can convert other formats to 24p (or any format to any other format) without any kind of a plugin or third-party application support and is the only proprietary NLE that allows for multiple instances of the application to be opened simultaneously. Clips and sequences can be copied and pasted between instances of Vegas. One instance can be rendering a sequence in the background while the user continues to edit in a different instance of Vegas in the foreground. Vegas provides sophisticated compositing including green screen, masking, and keyframe animation. Nesting allows a prior project to be included in another project modularizing the editing process so that an array of tracks and edits become one track for further editing. Any changes to the previous project become reflected in the later project. Nesting is especially helpful in large or complex or special effects projects as the final rendering suffers no generation loss.

Unlike other editors, Sony Vegas Pro supports scripting technology which provides task automation, simplified workflow, and greater efficiency and productivity. Scripts and extensions Free and paid for pre-written scripts are available from the Vegas community on the web.
