Editing DirectShow (section)

==DirectShow Editing Services==
''DirectShow Editing Services'' (DES), introduced in DirectX 8.0/[[Windows XP]] is an API targeted at video editing tasks and built on top of the core DirectShow architecture. ''DirectShow Editing Services'' was introduced for Microsoft's [[Windows Movie Maker]].<ref name="QuartzIntro" />  It includes APIs for timeline and switching services, resizing, cropping, video and audio effects, as well as transitions, [[Keying (graphics)|keying]], automatic [[frame rate]] and [[sample rate conversion]] and such other features which are used in [[non-linear video editing]] allowing creation of composite media out of a number of source audio and video streams. DirectShow Editing Services allow higher-level run-time compositing, seeking support, and graph management, while still allowing applications to access lower-level DirectShow functions.

While the original API is in C++, DirectShow Editing Services is accessible in any Microsoft .NET compatible language including Microsoft [[Microsoft Visual C Sharp|Visual C#]] and Microsoft [[Visual Basic .NET|Visual Basic]] by using a third-party code library called "DirectShowNet Library".<ref>{{cite web|url=http://directshownet.sourceforge.net/about.html|title=About DirectShowNet Library|work=DirectShowNet SourceForge Website|publisher=SourceForge|access-date=2010-08-18}}</ref> Alternatively, the entire DirectShow API, including DirectShow Editing Services, can be accessed from [[Borland Delphi]] 5, 6 and 7, [[C++ Builder]] 6, and from later versions with a few minor modifications, using a third party software library called "DSPack".<ref>{{cite web|url=http://www.progdigy.com/?page_id=4|title=The DSPack Project|access-date=2010-08-18|archive-date=2010-06-14|archive-url=https://web.archive.org/web/20100614052106/http://www.progdigy.com/?page_id=4|url-status=dead}}</ref>
