Complementary material to the paper. Movies showing different magnitudes during the evolution of the neutron-star white-dwarf merger. All the movies show slices through the orbital plane (on the left) and perpendicular to the orbital plane (on the right right) centred on the neutron star. The region where the gravitational potential is softened around the neutron star is outlined by a black-dashed line. The different videos show the following magnitudes: the ratio between the magnetic pressure and gas pressure (beta), the density, the entropy, the absolute value of the magnetic field, the radial velocity with respect to the neutron-star and the temperature. For every magnitude there are two videos (_01rsol and _003rsol) showing them in a box of 0.1 and 0.03 solar radii respectively.
