DScaler is an open-source video deinterlacer and scaling program for Microsoft Windows. Version 4 is a complete standalone program, while version 5 is planned to be a DirectShow filter. The last publicly committed change to the source code was on 2 April 2012, suggesting the project has been abandoned.
From Version 4.1.17, Direct3D output and Windows Vista x64 are supported as a test version.
