Almost all data lost! Prelude CC

Posted by Toni Tillmann on April 6, 2014 at 11:09 am

Hey guys,

as there is no dedicated Prelude forum I chose the the Premiere Pro forum as the closest option.
Please move the thread if there is a more suitable spot for my issue.

I am experiencing a huge problem with Prelude CC that will most probably cost me a week of work if I can’t solve it. Any ideas welcome.

Setup:
iMac 2,4GHz, OSX 10.9.2
Areca Thunderbolt RAID 10
Adobe Creative Cloud Prelude CC v2.2.0

The issue:
I have ingested about 1,5TB of footage of mixed kindes of formates:
– ProRes 4444
– ProRes 422 (HQ)
– MXF
– .jpeg
– H.264 .mov

The whole ingest procedure has been relealized within Prelude CC on a MacBook. After that we copied the Prelude project onto the iMac and relinked all clips -> no problemo.
I created a specific set of subclip presets and started tagging. I spent about a week of creating supclips with different kinds of discriptions to get an idea and structure of the mass of footage.
Everything went fine and I manually copied the project two days ago to a different location, renamed it as backup, locked the file and continued work on the original one.

Just today we opened Prelude again and found out that ALMOST ALL SUBCLIPS WERE GONE!! The weird thing is that some folders kept their subclips but most of them didn’t.

I tried the following to resolve the issue:
– close/reopen
– restart computer
– look for auto-backups / found none
– After having no success with the above approaches I tried to open my backup-file. Turns out that also my backup file lacks most of the subclips.
– I copy the file to the macbook / same issue
– Finally I opened the file in Text Edit to check the project struktur: I find out that all media links and subclips are beeing saved within the project file and that all my subclips are also missing within the file.

After realizing this, I am allmost sure that there is no hope to get my project file back to life and that I have just lost a week of work.

What I need to make sure/find out,tho, is the following:
– Has anyone encountered similar problems?
– Did I make a mistake?
– How could that happen?
– Is it possible that sth like this will happen again?

I really need to pin that problem to make sure that I won’t loose another week on the project as I have none to spare.
Otherwise I will start editing right within Premiere CC.

Please let me know if you have any ideas/solutions/questions to the issue.

cheers guys
Toni

Hi Toni,

Prelude CC doesn’t actually save subclips, markers etc… in the project file, but in the video file XMP metadata. That can either be a sidecar file or embedded in the file itself. You haven’t by any chance been deleting XMP files?

Hi Helge,

thanks for your quick reply.

First of all I double checked my project and tried to make sense of the file type issue. I found out that ONLY my subclips of the Alexa footage / mov clips are missing. All subclips referenced to a C300 file /MXF and GoPro/MP4 are still there. I can also see the .XMP files you are talking about.

That makes me wonder as I’ve heard that stored subclips liked to .mov inside the clips. And they are all gone…

thanks for your help.
cheers
Toni
