4 video: -Ve Amplitude Modulation dat 2 VSB-SC why not FM although it has so many advantages (like noise immunity) is bcoz of video sgl has more bandwidth which is difficult to frequency modulating.
+Ve AM: When white level (of picture) comes it is difficult to remove the carrier sgl at receiver side but our requirement is to remove the carrier sgl (after modulation) at receiver side right!!! So we go for -Ve AM in this we can easily remove the carrier.

4 Audio: FM modulation.
