Clips suddenly "lost" video track

Feb 22, 2013 8:07 PM

I have a bunch of clips from a Sony FS700 in a bin.  They are all 1080p@23.98 .MTS files.  I set markers, then created a multi-cam source sequence from 9 clips.  When I opened this sequence in the source monitor, all 9 angles were offline, so I deleted the sequence to try again.  But now, 4 of these clips have "lost" their video track.  The properties window shows audio only.  I'd like to figure out why this happened. 

My only guess:  I turned on Audio Time Units before placing the markers, in order to sync the shots perfectly, because it's a musical performance.  Maybe Premiere didn't like that?


Edit:  More importantly, how can I get these clips back?  I removed them from the bin, deleted their XMP files, and re-imported.  But they still show as audio-only clips.

    Did you move the clips?  Did you have them on an external drive that got assigned a new drive letter when you re-attached it?  Did you copy the entire folder structure from the card to your hard drive and then use Pr's Media Browser to import them?

     

    Another consideration: check your new sequence presets.  Are they all there or are some missing?

    I see this happen on occasion.  I'm always able to get things back to normal by opening an empty PP project.  From there I delete the Media Cache Database under Preferences>Media.  Then I close PP and delete the actual Media Cache files using Windows Explorer.

     

    Upon reopening the project, the Cache files need to be rebuilt, but they all work after that.

    Thanks.  I actually got the clips back already by deleting them from the bin, then deleting the cache files in Finder.  If it happens again, I'll try just deleting the cache files.

    Have you noticed any pattern to what causes this?  Is it a known bug?
