Lets not forget the fact that these are all high impedance circuits. You could just make an "unun" transformer. So you have 1v p-p composite in, and you need 10v p-p out? 1:10 matching transformer. Phase inversion is easy if you use a 1:1 isolation transformer (There are many made just for video.) and flip the output phase. You can also combine both. Invert the phase and derive 5v p-p baseband via a swapped output 1:5 ratio unun.
