Where each one falls short

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

IINA

  • There is no Apple TV or iOS app, so it cannot be used for a living room streaming setup the way Infuse can.
  • It has no polished network share or cloud storage library browser, so streaming from a NAS or cloud drive is more manual than with Infuse.
  • As a volunteer open source project, new feature development and bug fixes depend on contributor availability rather than a funded team.
  • It is Mac only, so there is no equivalent app for Windows users in a mixed household.
  • Advanced mpv configuration is still exposed for power users, which can be confusing for someone who just wants simple playback with no options.

Synthesia

  • Free plan limited to 10 minutes of video per month
  • Starter plan limited to 10 minutes of video per month
  • Creator plan capped at 30 minutes of video per month
  • SSO/SAML authentication restricted to Enterprise tier
