When You Need Subtitles From Audio Alone
The episode audio becomes an SRT file you upload with the video version, so captions are ready the day it goes live.
A clip over a cover image or a waveform needs captions; the SRT comes straight from the audio track.
Narration recorded first gets its subtitle file early, so the editor can cut the picture to the timing.
What the SRT File Looks Like
A plain-text file any player and editor reads. This is what you get from your audio.
- Each cue
- A number, a time range such as 00:01:14,200 --> 00:01:19,050, and the line of text
- Where cues break
- At the pauses the speech recognition found, so subtitles follow natural sentences
- Speaker names
- Optional: add the speaker’s name to a cue, on every cue or only when the speaker changes
- Other subtitle formats
- VTT and ASS from the same transcript on paid plans
- Other languages
- Translate the transcript and export an SRT in each language, with the same timing
- Editing
- Fix words in the editor while listening; the timing of the line stays the same
- Free plan
- SRT export is included in the 30 free minutes
Before You Export the SRT
Audio-only subtitles are easier to fix now than after they meet the video.
Intro
Keep the audio and the video the same length
If the video adds an intro or cuts the start, the SRT will be early or late. Shift all subtitles in the free subtitle editor rather than re-transcribing.
Names
Fix names before you export
A misspelled guest name repeats in every cue. Correct it once in the transcript, or add it to My terms.
Platform
Check the platform’s caption rules
YouTube, Vimeo and social apps read SRT; some prefer VTT. Export the one your platform asks for.
