Then I do MVDegrain on source2 using the notes from source that was stored in idx1. If source2 has the same motion as source (it's a deblocked version), would this be OK?

Practical answer: Try this:

source = last
source2 = source.flipvertical()

backward_vec2 = source.MVAnalyse(isb = true,  delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)
backward_vec1 = source.MVAnalyse(isb = true,  delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec1  = source.MVAnalyse(isb = false, delta = 1, pel = 2, overlap=4, sharp=1, idx = 1)
forward_vec2  = source.MVAnalyse(isb = false, delta = 2, pel = 2, overlap=4, sharp=1, idx = 1)

source2.MVDegrain2(backward_vec1,forward_vec1,backward_vec2,forward_vec2,thSAD=400,idx=1)

This should convince you that something is fishy when not using idx as I told.
