I’m using Tumble 3D in FCPX and it’s exporting as one letter also. But I used the same title in three places within my project. It’s been a single letter in just the first instance after exporting.
I made the title then exported the short one minute clip to use during the next 18 shows. Once my show is edited I open the title project where I save the Tumble 3D title and copied it. I re-opened the show and pasted the title where I wanted it. Then I made the changes in the title and copied it to the second place in the show then again at the end of the show.I went back to the first title in the show and checked it. It was correct. Then I check the other two instances within the show and again they were correct. I went back once again to the front of the show and check it for a third time. All was well. So I exported the show.
Once exported I checked the external HDD where I sent the show and found the the first instance of the title was rendered with only the first letter. I checked the other two instances and they were fine.
I’ve seen this happen with some lower thirds in a different style also. Makes no sense!
