I've a very very odd issue that's been happening for a while. Clips are just disappearing from my timeline. Now originally I thought I may be accidentally deleting a secondary storyline group, but this is not the case. It has happened in various projects since 10.1.3 and continues in 10.1.4. Issues:
- Clips edited into a secondary storyline just vanish
- Gap clips are randomly changing length
I've taken to placing markers where my secondary storyline sections start and end then I can keep track of any that 'shrink'. The present project I'm working on, about 50% of the secondary storyline has just vanished. I open a backup of the project from 30 mins ago, it is all there.
This is obviously a major issue. Has anyone else had this? If I edit just with the primary storyline, clips do not disappear from this.
Yes, try with a new admin account. This is not a solution, but it's a solid check to determine were this issue is related to FCP X or to your general setup. If everything works fine with a new account there are some steps you can take to solve this without having to do a clean install of your OS.
BTW, could you point me to that older post? I must have missed it at the time.
If you are working with the latest version of FCP X and Yosemite and you are not working off a shared storage system using sparse disk images I would suggest you create a new admin account to see if you still have the problem when running FCP X on a fresh user account. If the problem goes aways using a new admin account post back so we can show you how to solve the issue, hopefully without needing to do a fresh install of your OS.
I am also having this problem and it is very very very frustrating. I recently upgraded from FCP 10 to 10.1.3 and a new Macbook Pro, Yosemite, 2.8 GHz Intel Core i7, 16 GB 1600 MHz DDR3.
I make changes to videos and TV programs, export and find that clips (especially cutaways/lower thirds) just disappear. I thought I was imagining it, then after a client asked me to make 1 change to a file, and after making it, there were 3 "new" errors, I started searching and found this thread.
For what it's worth, here's my addition to try and solve (or bypass) the issue of disappearing clips on timeline.
I've had this problem since today and I've read several posts on the issue. I have trashed Preferences, open FCPX and my clips had still disappeared. While trying to replace the disappeared clips, I came across what looks like an illogical buggy behavior.
This is what, I think, causes this bug to happen from me on FCPX 10.1.4 (as shown on the attached screen grab of my secondary screen):
Selecting clips on the primary timeline with the Position Tool ('T' hot key) and trying to move them along, I get an odd artefact (red rectangle on the screen grab). I applied the change then Zoomed Out (Shift+Z), and saw that other clips in the timeline had disappeared. When I hit UNDO (Cmd+Z) & REDO (Shift+Cmd+Z) I saw exactly the clips that had disappeared - BINGO!
It doesn't do this every time you select with the position tool, so keep an eye out for when you see this behaviour: UNDO, Check all is alright, and start again!
