What is an SRT file?
SRT (short for SubRip) is a plain-text subtitle format — the most universal one there is, supported by almost all software, platforms, and social networks. It is a "sidecar" file: it sits next to your video and tells the player what text to show and exactly when, instead of being burned into the picture.
Each caption in an SRT file has four parts:
- A sequential number (1, 2, 3…) for each caption
- Start and end times separated by an arrow —
-->— in the formathours:minutes:seconds,milliseconds - The subtitle text itself
- A blank line marking the end of the caption
1 00:00:00,498 --> 00:00:02,827 Here's what I love most about food and diet. 2 00:00:02,827 --> 00:00:06,383 We all eat several times a day,
That spec is exactly what our generator produces — which is why the files work in YouTube, Vimeo, VLC, Premiere, Final Cut, and every other SRT-compatible tool without conversion.
Subtitles do more than help hearing-impaired viewers: they make your video searchable and indexable by search engines, open it to global audiences via translation, and keep viewers watching in sound-off environments.
Frequently asked questions
What is an SRT file?
SRT (SubRip) is the most universal subtitle format — a plain text file with numbered captions and start/end timestamps, supported by almost all software, platforms, and social networks. The Library of Congress describes it as the most common sidecar file for pre-recorded web video, preferred by platforms including YouTube.
How do I generate SRT subtitles?
Upload a video or audio file, wait for the AI transcription to finish, then click the SRT export button. The file downloads ready to use.
Does the SRT include timestamps?
Yes. Every line is generated with start and end timestamps formatted to the SRT spec — hours:minutes:seconds,milliseconds with the --> separator — which YouTube, Vimeo, and video editors expect.
How do I use an SRT file with a video?
Give the SRT file the same name as the video (MyVideo.mp4 and MyVideo.srt), place them in the same folder, and most players (VLC, YouTube upload, editing software) will load the subtitles automatically.
What is the difference between SRT and SDH subtitles?
SRT shows just the dialogue. SDH (Subtitles for the Deaf and Hard of Hearing) also includes sound effects, speaker names, and other audio cues. Both use the same SRT file format.
Is SRT generation free?
Yes. You get 5 free transcriptions per day with no sign-up, including full SRT and VTT export.
