Error: PluralEyes could not prepare media to synchronize

This error typically occurs if:

• There is not enough space to create the necessary temporary media files. In order to create its temporary media files, PluralEyes needs as much space as all of the media in the timeline you're trying to sync (e.g. a 10GB project would need 10GB of hard drive space).
  
  Solution: Either create enough space on your hard drive to accommodate your project, or use the Preferences menu in PluralEyes to adjust where temporary files are stored to a drive with more room.
• The media or temporary file storage locations have read/write access issues. In order to prepare media files, PluralEyes needs to be able to see (read) the media in its timeline and create (write) temporary files in its assigned directory. 
  
  Solution: Either move the media itself to your local drive (instead of an external or network drive), and/or use the Preferences menu in PluralEyes to adjust where temporary files are stored to a local drive. The user Library or Desktop is a reliable location to move files into to check if read/write access issue is the problem. 
• 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 the program is reading and checking the entire file path to the files it's directed to.

Please note: PluralEyes has been discontinued as of February 1st, 2024. We cannot offer additional technical support should issues persist. More details can be found at this FAQ.
