A subtitle file summary is produced from an existing SRT, VTT or plain-text transcript rather than from the video itself. Since the words are already written down, no speech recognition step is needed — the language model reads the file directly and condenses it, which makes the process faster and removes transcription error entirely.
Both are plain-text subtitle formats with timestamped lines. SRT is the older and more widely supported one, using comma-separated milliseconds. WebVTT was designed for the web and allows styling and positioning metadata alongside the text. For summarizing, the difference is irrelevant — both parse to the same words.
A transcript already contains everything a summary needs, and reading text is far faster than processing audio. Starting from a subtitle file also removes the largest source of error: if the words are already correct, the summary cannot inherit a mis-heard name or number from the transcription step.
