  • Audio Quality Dependency
    The accuracy of subtitle synchronization relies on the quality of the audio track, and poor audio can lead to less precise results.

    As an open-source project, FFSubSync might not have the same level of support or documentation as commercial software, which could be a barrier for some users.
  • Requires Python
    Installation and operation require Python, which may necessitate additional setup for users not already using Python for other applications.
