Music, crosstalk, strong accents and phone-microphone audio all cost accuracy. The .srt is plain text, so fixing a line takes seconds.\u003c\/p\u003e\n\n\u003ch3\u003eHow fast is it?\u003c\/h3\u003e\n\n\u003cp\u003eA 14-second clip took about 5 seconds end to end on an ordinary laptop, including re-encoding the video.

The app works with the internet disconnected.\u003c\/p\u003e\n\n\u003ch3\u003eWhich languages does it handle?\u003c\/h3\u003e\n\n\u003cp\u003eThe engine knows over 90. English is excellent with the installed model; other languages need the larger model, which the app downloads once at your request. Translation goes into English only, and is weaker than transcription - read it before publishing.\u003c\/p\u003e\n\n\u003ch3\u003eCan I get subtitles without changing the video?\u003c\/h3\u003e\n\n\u003cp\u003eYes. Turn off \"burn the captions in\" and you get only the .srt file, which YouTube and most platforms accept directly.\u003c\/p\u003e\n\n\u003ch3\u003eCan I put my own brand on the software?\u003c\/h3\u003e\n\n\u003cp\u003eYes.
