Just wanted to say that the ColourLike method is the best. The BDluma+DVDchroma doesn't work because the framing is different and the chroma is off by a few pixels, in all of them but most visible in the closeup of Neo.
BDluma+DVDchroma would work much better if there was a way to do image registration on each frame to make them exactly matched.
By the way, an important thing to do when using ColourLike is probably to crop away the black borders before applying it. Otherwise it might pick up some dark color artefacts which often exist in the black borders of compressed video, and use those in the calculation.
