PLZ HOW I CAN T USE THE COMPRESSOR AFTER FINAL CUT PRO X WHY???????
HOW I CAN EXPORT MY VIDEO FROM FINAL CUT PRO X TO COMPRESSOR TO YOUTUBE???
You don't need to use Compressor. In FCP, Share>You Tube and then choose the quality setting you want.
Alternatively you can use Compressor to give you more control over your settings. If so, choose Share and either export a master file and bring that into Compressor…or SHare>Add Destination>Compressor settings.
Good luck.
