What is an SRT file and why do I need one for my video?

SRT (SubRip Subtitle) is the most widely supported subtitle format. It's a plain-text file with numbered cues, each with a start and end timecode and the line of text to show. YouTube, Vimeo, Premiere Pro, Final Cut, DaVinci Resolve, and most LMS platforms all accept SRT directly.

What's the difference between SRT and VTT?

Both are caption formats that share the same basic idea — timecoded lines of text. SRT is older and simpler; VTT (WebVTT) is the modern HTML5 standard and supports a few extras like styling and positioning hints.

How accurate are Whisper's subtitle timecodes?

Whisper produces word-level and segment-level timestamps that are accurate enough for most published video work, especially on clean dialogue. On music-heavy tracks, overlapping speakers or very fast speech you'll usually want to scrub through the cues and nudge a few.

Can I edit the SRT before exporting?

Yes. A hosted Whisper tool lets you edit the transcript line by line in the browser, then export the corrected SRT.

Will the SRT include speaker labels?

If you enable speaker detection before exporting, your SRT cues can be prefixed with labels like 'Speaker 1:' or names you've assigned.

What's the line-length limit for SRT cues?

There's no hard maximum, but two readable conventions are: keep each cue under ~42 characters per line, and aim for cues of 1-2 lines that stay on screen for 1-7 seconds.

Can I burn subtitles into the video instead of using a sidecar SRT?

That's a separate step. WhisperAI exports the SRT/VTT file; you then load it into your video editor (Premiere, Final Cut, DaVinci) or HandBrake to burn it in.

Whisper-quality SRT subtitles, straight from your video.
