Hey Ludmil,
Sorry, just back on my work-station, and watched your video. As a side note, I always turn off preview in Media Encoder when exporting. As I in any case have to watch the master after render.
If still not working, I would try one of follwing two:
1) Open your Productions project, then set up a new project that is NOT Productions. In the new project create an empty sequence with the same settings as your original sequence. Hightlight all clips in the original sequence, COPY, then Paste into new project and see what happens?
(Keep in mind that Adobe this last week has killed the Cloud part of Creative Cloud on many of their video based apps, there is every chance that they have made a mess of it. And, that this might be what you experienced by being able to export 7 days ago, but now it won’t budge)
2) Start exporting your time-line out in chunks, forexample Pro-Res HQ, and eventually build a new master sequence from that. This way you will also be able to narrow down where the issue might be hiding. Maybe also do a Wav file out of all audio, just to check that is not playing havoc with your export.
As a bonus question: As you are exporting 12 episodes, how are the other episodes behaving on export?
And then there is the elephant in the room, your Mac Studio, have you upgraded the OS on that in the last week?
I have a client who has just sent me advisory notes on NOT updating to the latest OS, as that gives problems when using FCPX – yep, you could not make it up, because of Apple’s apathy to FCPX, one can not trust that the next upgrade will work. This specific client is very dilligent in their tests, and sometimes us freelancers are made to wait for up to 12 months before we can update FCPX, simply because various version out of Apple does not conform to a previous version.
Hope that this helps.
Do let us know when and how you resolved the issue?
