Timeline content temporarily disappears only to Return on Zoom. Screenshots attached.

Hello,

I have an odd problem where I have a black space (not slug) where video & audio used to be in my timeline, but it still plays and outputs. If I zoom in or out of the timeline, the audio and video will reappear only for a different part of the timeline to disappear. This is FCP X 10.2.2.

This is different than some of the threads where timeline goes black and does not play. This plays.

Right before this problem, the external drive that holds this library was accidentally disconnected from the mac while it was still in use (not rendering or anything, just standing by, but connected to an open FCP). So I am sure it is related to that bad disconnect.

Previous project versions of this edit, that are also in this same library, do not have this issue. But a Duplicate of this, affected project does have the issue.

I have attached some screen shots.

I have deleted my preferences (restarting FCP while holding command+option), cleared out RAM, restarted FCP, rebooted Mac, etc.. But the problem persists.

Also - when I open the small window to the left of the Timeline (I forget the name - it ID's the clips) - when there is black space it states: space. When the audio or video returns, it ID's correctly.

And ideas on what else can be done to restore? I have never used the FCP generated backup copy, nor know how to - but would this be an option to possibly find a backup that may have been taken at some point today - possibly prior to the bad eject?

I do have manual backups of this project on another drive , but today we did a considerable amount of work and hoping not to have to re-create all of today's work.

Thank you in advance for any help!


1. This is what problem looks like:



2. Zoom In/Zoom Out of Timeline and it comes back (This is same sections of Timeline)



3. Black space to left of video in Timeline is the problem area.



4. Zoom in, all returns to normal.

Probably just a corrupt file.

Try trashing preferences and re-launching FCP X.

(Hopefully, you have good backup practices so you can go back a version or two if it's necessary.)

But it's likely that re-booting and clearing out the Prefs cache will solve things.

Good luck.

I know you said you "cleared out RAM" but have you deleted your cache?

Also, it might be worth making a new Project and then copy and paste your timeline from the bad one to the new one.

The restore from backup command is File > Open Library> From backup.

That will open a new instance of the library from the time of your choosing.

Jeremy!

Copying the timeline into a new project appears to have solved the issue!! Thank you so much. Drinks. Dinner. are on me.

I cleared the cache (using CleanMyMac 3 for anyone that may have a similar need) but, unfortunately, did not fix this specific issue. But creating the new project did solve the issue.

Thanks again!!

Glad it's working for you.

Also, just in case anyone else looks at this post in the future, the Delete Cache menu is a bit contextual, meaning if you have a Project, Event, or Library, that menu can change.

File > Delete Generated Project (or Event) (or Library) files.

And, if you keep the cache outside if the Library (which I tend to do) you can simply grab the entire Cache package and trash it. This gets rid of render files as well as Thumbnails and Peaks data, which is suspect (but don't have hard evidence on) causes display issues.

Making a new Project starts a new set of cache files, which seems to help some times.

Jeremy
