Motion transitions are not reproduced when converted with Compressor

I don’t know why that happens. I can say that I have never been a fan of “send to Compressor”.

Two easy alternatives are:

1) Export with Compressor Settings - add a new destination in FCP, choose Compressor Settings and choose the settings you want. Then you can share right from FCP and don’t even need to open Compressor.

2) Export a master file from FCP and then convert to whatever format you want in Compressor.

Option 1 is best if you just want one output file.

Option 2 is best if you want to use Compressor to produce several different outputs from the same input.

Given those two, I never ever use send to Compressor, except sometimes to do tests when addressing questions on this forum.

Thank you Luis for your answer (I am the original questioner).
Option 1 that you suggested solved the problem.
Thank you very much.
