m2ts file in original transfer location syncs audio fine, copied to new location, it doesn't.

Jun 22, 2013 11:48 AM

I moved the entire folder for the m2ts file in question from the storage drive to which I originally copied it (from the SD card) to the drive where my active project's video files. my working files, are located.

 

When playing back the copied file in my source monitor before or after import, or on my timeline, the audio appears to lose sync. Upon careful listening, however, it appears there are actual jumps in the audio as if someone randomly ripple edited the audio.. A total of about five minutes of audio is missing.

 

If I play the file from it's original location It's ot a problem.

 

Both files regardless of location, however, play fine in VLC (VideoLAN).

 

Any insight into why this is happening and how to fix it?

 

Again, I am copying the entire folder and it's contents, all the files related to the clip.

 

Thanks in advance.

    You should try deleting your Media Cache files.

    Edit > Preferences > Media

    Under 'Media Cache Database' hit 'Clean'.

    This will delete the Database only.

    Navigate to the location specified under 'Media Cache Files',

    open the folder, select all and delete.

    The Media Cache Files and Database will automatically re-generate

    when you re-open your Project... allow plenty of time for it to finish.

    No dice. Same problem I even tried copying each file within the folder separately and still no dice.

    Did you:

     

    1. Open your project with the media files in the original location,

    properly linked, and properly synced.

     

    2. Delete the Media Cache Database as described in post #1,

    exit Premiere, navigate to, and delete the actual Media Cache files.

     

    3. Move your media to the new location.

    =or=

    After copying your media to a new location,

    temporarily (or permanently) rename the original location folder.

    (Otherwise, Premiere will look to the last known path for the media files,

    even if you have copied the media to another location).

     

    4. Re-open the project, then link the media files to the

    new location when prompted.

     

    5. Allow the Media Cache generation to fully complete.

    It didn't occur to me I might have to exit Premiere to break the old link.

    You have to break, then re-establish the link to the media files in their

    new location in order to regenerate the corrected Media Cache files.

    I still don't understand why the original copied file had randomly truncated sections of audio.

    Probably because you had confused or duplicate Media Cache files

    or a corrupted Media Cache Database as a result of your failed attempts

    to relocate the media.
