Shadows change in Matinee

I change my r.Shadow.RadiusThreshhold to 0 and my r.Shadow.TexelPerPixel to 20. This fixes my shadows but as soon as I render out a sequence from Matinee the settings in the rendered out sequence are back to what they were before!
Is there a standard file where I can those settings? Maybe it reloads those in Matinee!

Kind regards, Pip
