All this suggestion works with some of the clips, but not for all. weird...
I was doing this test with the 2 shorter clips of the 12 I'm working with, and I found out those clips dont pass the TC to compressor (well, they do, but nto in the transcoded file, what is even more weird), and there are 2 other clips that dont do that, I dont know why because is same camera and specs, but they do though FCPX to h264/prores.
so clips 1,4,5 and 9 have this problem, the way I could solve it in order to to pass the TC to Compressor is creating a new project for each of this clips and copy paste the TC in the dialog. So the transcoded projects of clips 1,4,5 and 9 now have the TC in H265.
The big problem with this method is 120fps clips are forced to be 60 fps as FCPX doesn't have option beyond 60fps, so I had to slow time x2 in order to keep all the frames, so in next step the editor can do slow motion or normal speed as he will.
