Sony Vegas Pro is a video
editing software package for non-linear
editing (NLE) originally published by Sonic Foundry, now owned and run
by Sony
Creative Software.
Vegas does not require any
specialized hardware to run properly, allowing it to operate on almost any
standard Windowscomputer 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.
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. Free and paid pre-written
scripts are available from the Vegas community on the web.
