What is Video to SRT?
Video to SRT converts the speech in a video file into a caption file: numbered cues, each with a start and end time, and lines kept short enough to read on screen. MP4, MOV, M4V, WebM, and WMV files are accepted without a separate audio export. The result imports into video editors, media players, and platform caption fields.
Why choose Video to SRT?
Video to SRT keeps the caption file and the video on one timeline: every cue points to the second in the clip where it was spoken. Editors get a sidecar file they can import and nudge, and creators get captions for an upload without building a cue sheet by hand.
Still Timing Video Subtitles Cue by Cue Inside an Editor?
Caption work in an editor is slow because every cue is typed first and then dragged until the words agree with the waveform. A ten-minute clip can take an hour, and a re-cut throws the timing away. Video to SRT builds the cue sheet from the clip's own audio, with sequential numbering and timecodes that import into an editor, so the first pass becomes a review instead of a transcription.
What makes Video to SRT different?
Video to SRT delivers a caption file rather than a wall of text. Cues are numbered, timed to the clip, and short enough to stay on screen for the length of a spoken phrase.

How to use Video to SRT in 3 steps
- 1
Add the video file
Upload an MP4, MOV, M4V, WebM, or WMV clip, or paste a link to a video that is already online.
- 2
Set language and speakers
Confirm the spoken language and turn on speaker separation when the clip contains an interview or a panel.
- 3
Download the SRT
Check where cues break and how long each line stays up, then download the file for the editor or the platform.
Take one finished clip and run it through the caption step before committing to a series. Video to SRT produces a sidecar file that can be imported, nudged, and uploaded alongside the video.

Frequently asked questions about Video to SRT
Which editors can import the SRT file?
The exported SRT follows the standard subtitle structure that editors such as Premiere Pro, DaVinci Resolve, Final Cut Pro, and most media players read without a plugin. Some tools ask for a frame rate or a text encoding during import; UTF-8 and the project frame rate are the usual safe choices for a caption track.
How long should each cue stay on screen?
A cue needs to be readable at the speed a viewer reads, which is slower than speech. Video to SRT splits at natural pauses and keeps lines short, but a dense passage may still need a break moved by hand. The review step matters most for fast talkers, numbers, and technical terms.
Does the SRT come burned into the video?
No. The output is a sidecar caption file, separate from the picture, so a platform can toggle captions or an editor can restyle them. Burning text into frames happens later in an editor, and keeping the file separate means the same clip can be re-captioned or re-timed without another export.
Can several languages be handled in one video?
Language detection works best when a clip runs in one language. A video that switches language mid-scene is better split into segments and processed with the language set by hand for each part. A bilingual interview therefore yields a cleaner caption file in two passes than in one.
How accurate are the timecodes?
Cues are aligned to the speech in the uploaded file, so they follow the waveform of that clip. Trimming or re-timing the video after export shifts the captions, which is why the SRT should be generated against the final cut. A quick look at the first minute reveals whether anything needs nudging.
Can a cue be edited after the file is generated?
Yes. Text, cue breaks, and speaker names can be changed in the transcript view before download, and the exported file carries those edits. That is usually enough for names and jargon. Timing that needs frame-level precision is still a job for the editor's caption panel.
Is there a limit on video length or size?
A file can be up to 100MB and its speech up to three hours. A long video at a high bitrate may reach the size limit first, so exporting a review copy at a lower bitrate, or submitting the clip in sections, is the practical approach for a feature-length recording.
Is an account needed to make captions?
No account is needed to generate a first caption file. Signing in keeps prior transcripts and raises the daily allowance, which helps when a series is being captioned episode by episode. Nothing has to be installed, and the browser handles the whole path from video to SRT.
