Hi Eddie Adams
I’ve had the exact same problem. And first I thought the problem was solved when I switched on the “Linked selection” button on the top right corner of my timeline. But the problem re-occured… Still I think this is a sequence settings problem.
Here is the solution for what has worked for me:
In the bottom LEFT corner of Final Cut Pro (where your viewing options are…) there is a VERY tiny arrow head pointing to the RIGHT . Click this. A menue will pop up and the third selection from above is called something like “Display linked edit marks” -I really cannot give you the exact same name that I have because I am working on a non English keyboard… so please try to match it with the correct selection in English. – I have FCP version 7.0.3 btw. In the window that pops up it will be the third one from above. Right below “show audio wave form” if this is any help—-
So when I opened FCP and created a subclip the settings of my first sequence had the “Display linked edit marks” selection checked and I got the same error message you got when I tried to delete anything from the timeline. Whatever I’ve tried, nothing worked, and I’ve tried for hours…
Then I unchecked “Display linked edit marks” after a click on that little arrow head and then created a new sequence and tried to create the same subclip again.
YEAH!!! Now I could delete and change the subclip and later more subclips without ANY problem. 🙂
I hope this helps. If not I have to say I have NO alternative solution. Please let me know if has worked for you. I’d be curious.
Good luck, all best!
