I should have paid more attention to your command line, in that case you are going between the same pixel format and I'm not sure that the use of the scalar for converting between different colour difference encodings will actually do anything as I believe it only considers using the matrices if the pixel formats go between a difference encoding and RGB.
Going between two encoded video signals you might have to use the colour matrix filter, to get 'correct' behavior. Still won't stop some decoders making assumptions, though.
