Editing VirtualDub (section)

===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.
