Submarine Player: Offline English Subtitles and Transcriptions for Any Video
Submarine Player is a Mac application that automatically generates English subtitles for any video, regardless of the original language, and displays them in real-time during playback. Fully offline, it supports 19 languages and various video formats, including MP4, MKV, and AVI. Users can choose between fast or highly accurate transcription models, show dual subtitles for language learning, or display original-only captions. Subtitles can be exported in SRT, VTT, or CSV formats, and a transcription-only mode is also available—making Submarine Player perfect for both native viewing and multilingual accessibility without needing an internet connection.
