c2 = core.generic.Convolution(clip, [1, 2, 1, 0, 0, 0, -1, -2, -1], planes=0)
clip = core.std.Interleave([c1, c2])
clip = core.std.ShufflePlanes(clip, planes=0, format=vs.GRAY)
I originally think the result of the two will be identical, but it's not. However I am no expert at matrix convolution so I may misunderstand its functionality and use it the wrong way.  |
I believe you intended to compare between avs.mt_convolution(clip, '1 2 1', '1 0 -1') and generic.Convolution(clip, [1, 2, 1, 0, 0, 0, -1, -2, -1], planes=0), which looks quite identical to me....
