Error: PluralEyes could not prepare media to synchronize

This error typically occurs if:

• There is not enough space to accommodate the temporary media files.
  PluralEyes needs about as much space to create its temporary files as the media you're asking it to sync. So for example, if you are giving PluralEyes 10GB worth of footage and audio, it will need 10GB worth of space in the directory it is storing its temporary files.
  
  You can use the Preferences menu in PluralEyes to adjust where temporary files are stored.
  
  
• The media or temporary file storage locations have read/write access issues.
  In order to prepare and read media files, PluralEyes needs to be able to see (read) the media and create (write) temporary files from one location to another. In some setups (mostly Macs) there can be issues with this read/write access that can best be remedied by moving the location of the temporary or media files, to a drive more accessible to PluralEyes.
  
  The user Library or Desktop is typically a surefire location to move these files into to check if this read/write access issue is the problem. You can use the Preferences menu in PluralEyes to adjust where temporary files are stored.
  
  
• The media is stored on an unnamed or unmapped Network drive.Any network drive PluralEyes is trying to read from will need to be mapped and named in order to properly read its data and file structure, as PluralEyes is typically trying to check and read the entire file path to the files it's directed to.

If all of three of these factors have been accounted for, head into the Help menu of PluralEyes, select Report a Problem, and send it to Support.
