This is a developer-provided example on iPhone 16 Pro with iOS 26, including subtitle translation. Actual times vary with device, language and audio; NAS sources also depend on network speed. The free per-file limit is 30 minutes, so a two-hour file requires Pro.
Read the guideWhich OS is required?
