Editing VirtualDub (section)

==Features==
VirtualDub is designed for [[Microsoft Windows]] but may run on [[Linux]] and [[macOS|Mac OS X]] using [[Wine (software)|Wine]] (for example, to use it with the popular Deshaker plugin).<ref>{{cite web |url=http://forums.opensuse.org/new-user-how-faq-read-only/unreviewed-how-faq/429428-howto-install-virtualdub-under-wine-deshaker-plugin.html|title=HowTo install VirtualDub under wine with deshaker plugin|author=oldcpu|access-date=2010-01-13}}</ref> However, native support for these systems is not available.

VirtualDub was made to operate exclusively on [[Audio Video Interleave|AVI]] files; however, a plugin API was added from version 1.7.2 which allows the import of other formats.<ref>{{Cite web|url=https://virtualdub.org/blog2/entry_152.html|title=VirtualDub 1.6.18 and 1.7.2 released - virtualdub.org|website=virtualdub.org}}</ref> Appropriate video and audio [[codec]]s need to be installed.

===Video capture===
VirtualDub supports both [[DirectShow]] and [[Video for Windows]] for video capture. Capture features include capture to any AVI variant, audio [[VU meter]]s, [[Video overlay|overlay]] and preview modes, [[histogram]], selectable [[Cropping (image)|crop]] area, video [[noise reduction]], auto stop settings (based on capture time, file size, free space, and/or dropped frames), and designate alternate drive(s) for capture overflow.

VirtualDub can help overcome problems with [[digital camera]]s that also record video. Many models,{{weasel inline|date=September 2014}} especially Canon,{{which|date=September 2014}} record in an [[M-JPEG]] format incompatible with [[Sony Vegas]] 6.0 and 7.0. Saving AVI files as "old-style AVI" files allows them to appear in Vegas.

VirtualDub supports [[DV (video format)|DV]] capture from Type 2 (VfW) [[FireWire]] controllers only (It cannot work with Type 1). There is no DV batch capture, still image capture, or DV device control capability.

===Video assembly===
VirtualDub can create a video file from a series of image files in [[Truevision TGA]] or [[BMP file format|Windows Bitmap]] file formats. Individual frames must be given file names numbered in sequential order without any gaps (e.g. 001.bmp, 002.bmp, 003.bmp..). From those, the frame rate can be adjusted, and other modifications such as the addition of a [[soundtrack]] can be made.

VirtualDub can also disassemble a video by extracting its soundtracks saving its frames into Truevision TGA or Windows Bitmap files.

===Editing===
VirtualDub can delete segments of a video file, append new segments, or reorder existing segments. Appended segments must have similar audio and [[video format]]s, dimensions, number of [[audio channel]]s, [[frame rate]]s and [[sampling rate]]s. Otherwise, VirtualDub is incapable of mixing dissimilar video files or adding [[film transition|transition effect]]s between segments.

===Video processing===
VirtualDub comes with a number of video editing components known as "filters". They can perform basic tasks as arbitrary resize, converting the video to [[grayscale]], arbitrary rotation, crop, or changing simple values like brightness and contrast. Filters may be used during the video assembly as well. Filter plug-ins further extend VirtualDub's capabilities. A plug-in [[Software development kit|SDK]] is available for developers to create their own video and audio filters.<ref name=sdk>{{Cite web|url=https://www.virtualdub.org/filtersdk.html|title=Plugin SDK - virtualdub.org|website=www.virtualdub.org}}</ref>

Besides those basic features, its many third-party plug-ins make VirtualDub a "powerful"<ref name="SDA" /> open-source tool when it comes to linear video processing, and in fact most of the hundreds of third-party plug-ins available for VirtualDub are filters related to either aesthetic effects or cleaning, fixing, and restoring image quality, such as various denoising and sharpening methods targeted especially at analogue and digital video signal and film defects (be they related to [[VHS]], faulty cables, a distorted analogue [[terrestrial television|terrestrial]] or [[satellite television|satellite]] TV reception, or [[compression artifact|digital compression]]), [[deinterlacing]] and [[field (video)|fields]] manipulation, [[color space|colorspace]] conversion and manipulation, [[telecine#Reverse telecine (a.k.a. inverse telecine (IVTC), reverse pulldown)|reverse telecine]] aka IVTC, deflickering, deshaking, adding and removing logos and subtitles, analysis of video content, etc.

All of these processing features are fully [[Batch processing|batchable]] to apply the same effects on a large number of files.
