Sorry about the top post. I understand they are supposed to be the same -s and -vf scale, but I found that using -s caused many problems including these kinds of color shifts, maybe it's because there sometimes were other filters, but when I stopped using the -s option and used the -vf scale instead, I no longer saw the color shift. Perhaps there's a bug.
