[QUOTE="tourettes, post: 75216, member: 10858"] Haven't looked in cropping in DS filter, but one way I guess would be to use different resolutions in input and output and then manually copy the needed image frame portion to the output. Have you tried to use SetOutputRect from IVMRMixerControl9? Althou it doesn't seem to be advisable :) [url]http://msdn.microsoft.com/library/default.asp?url=/library/en-us/directshow/htm/ivmrmixercontrol9setoutputrect.asp[/url] "The IVMRMixerControl9 interface enables an application to manipulate the incoming video streams on the Video Mixing Renderer Filter 9 (VMR-9).
