May be for noisy source usefull other approach. We use only MVDegrain1 but using mask which calculate ME error and use previous, current and next frame or previous -2 previous current or current next next +2. This very good for my VHS capture source. Also we can use multipass. I think about this more time but can not formalizing. Also we need care luma value for dark scene we need degrease THSad.
yup.
