Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FreeFileSync

  • The interface is dense and functional rather than friendly, and the sync direction is easy to misread
  • Some convenience features are held behind the paid Donation Edition
  • The installer has historically bundled optional offers, which is worth reading carefully during setup
  • Not a versioned cloud backup: it synchronises what you point it at and nothing more

mpv

  • There is no graphical interface at all by default, so a typical non-technical user will find it unusable without significant setup.
  • It has no library browser, artwork fetching or organised media collection view, unlike IINA or Infuse.
  • There is no Apple TV, iOS or Android version, so it cannot be used for a living room or mobile streaming setup.
  • Configuration is entirely file and flag based, so getting a specific behaviour set up correctly has a real learning curve compared with a settings panel.
  • Because it is a general-purpose engine rather than a consumer product, there is no dedicated support channel beyond community forums and documentation.

Answered from the vendors’ own pages

FreeFileSync: Is FreeFileSync free?

Yes, open source and free. A paid Donation Edition adds convenience features such as parallel sync and portable installs.

mpv: Is mpv free?

Yes, entirely, and it is open source with no paid tier of any kind.

FreeFileSync: Is it a backup tool?

It synchronises folders and supports versioning, which covers many backup needs, but it is not a managed cloud backup service.

mpv: Does mpv have a GUI?

Not by default. It shows the video and a minimal overlay, but there are no menus, library or settings panel; IINA is the graphical Mac interface built on the same engine.

FreeFileSync: Can it sync to cloud storage?

Yes, including Google Drive and SFTP or FTP targets alongside local and network paths.

mpv: Can mpv play from network shares or cloud storage?

It can play many stream types via command line arguments, but it has no built in browsable network or cloud library the way Infuse does.
