SRT Generator: Turn Any Video into a Subtitle File
Upload a video, let the AI transcribe it into numbered, timed cues, correct anything in the editor and download a clean .srt file. VTT, TXT and JSON included.
SRT Generator: Turn Any Video into a Subtitle File Features
EchoWave's subtitle tools are used by YouTube channels, course creators, and localization teams worldwide
Timecodes, typed for you
The subtitle file, without typing a single timecode
An SRT generator saves you from the worst job in video: pausing every few seconds to type what was said, then hand-writing timecodes to match. EchoWave transcribes your video with word-level timing, splits the speech into readable cues and numbers them in sequence, so the .srt that downloads is valid the moment it lands. Correct anything first in the subtitle editor: fix a name, nudge a cue by 0.1 seconds, snap an edge to the playhead. Need a different container? The same transcript exports VTT for web players, plus TXT and JSON, or run any file through the subtitle converter. No audio at all? Type cues from scratch and time them against the playhead.

What you get
Everything between raw video and a valid .srt
Transcription writes the file, the editor makes it right, and four formats come out the other end.
-
Auto-Generated, Numbered Cues
Transcription with word-level timing turns speech into sequenced cues. The downloaded file carries clean sequence numbers and standard timecode ranges, so it opens correctly in players and platform upload checkers without hand-formatting.
-
Per-Cue Correction Rows
Every cue is an editable row with its own play button. Audition the line behind a doubtful word, fix names, jargon and punctuation in place, and the corrected text is exactly what lands in the file.
-
Precise Timing Controls
Nudge a cue's start or end in 0.1 second steps, or set an edge to the exact playhead position while watching the preview. Timing gets fixed by eye, not by timecode arithmetic.
-
SRT, VTT, TXT and JSON Downloads
One corrected transcript downloads four ways: SRT for platforms and players, VTT for web video, TXT for reading and JSON for pipelines. If the words matter more than the file, start from video to text.
-
50+ Languages In, 80+ Out
Source language is auto-detected across 50+ languages, with a manual override for noisy or mixed audio. Translate the finished cue track into 80+ languages with the subtitle translator and download a separate SRT per market.
-
Manual Cues for Silent Footage
No usable audio? Type or paste each line as a cue and time it against the playhead. Tolerant SRT import also loads an existing file so you can repair it in the same editor.
How it works
How to generate an SRT file from a video
Four steps from raw footage to a subtitle file that passes the upload check first time.
-
Upload Your Video
Open the EchoWave editor and drop in your video. MP4, MOV, WebM and other common formats load straight onto the timeline, ready for transcription.
-
Auto-Transcribe the Audio
Select the clip and run auto-transcribe in the captions tool. The AI detects the source language and writes timed, numbered cues. No usable audio? Switch to manual mode and type each cue instead.
-
Correct Text and Timing
Work through the transcript rows: play any line you doubt, fix misheard words, and nudge cue edges in 0.1 second steps or snap them to the playhead until every cue sits on the speech.
-
Download the SRT
Choose SRT as the export format and download the finished file, sequence numbers and timecodes included. Grab VTT, TXT or JSON from the same transcript if a platform asks for them.
Who uses it
Who needs an SRT file
-
YouTube Channels
Upload the SRT alongside the video so YouTube shows your exact wording instead of its auto-generated guesses.
-
Course Creators
E-learning platforms ask for a caption file per lesson. Transcribe each lecture, fix the terminology, and deliver a compliant SRT in minutes.
-
Localization Teams
Generate the source-language SRT once, translate the cue track into 80+ languages, and hand every market its own subtitle file.
-
Video Podcast Teams
Episodes on YouTube and Spotify ship with proper subtitle files, and the same transcript doubles as show notes in TXT.
-
Filmmakers and Festivals
Festival and distributor deliverables often require dialogue subtitles as a sidecar file. Export a clean, numbered SRT that matches picture.
-
Developers and Pipelines
JSON carries cue text and timing into apps and workflows, while SRT remains the interchange format every player accepts.

SRT generator FAQ
How do I create an SRT file from a video?
Upload the video to EchoWave, open the captions tool and click auto-transcribe. The AI listens to the audio and returns timed, numbered cues within moments. Read through the transcript rows, correct any misheard words, adjust timing where needed, then choose SRT as the download format. The file arrives with sequence numbers and timecodes already written, so you can upload it straight to YouTube, Vimeo, LinkedIn or any player that accepts sidecar subtitle files. It all runs in your browser, with nothing to install.
What is an SRT file, exactly?
An SRT (SubRip Subtitle) file is a plain-text format that nearly every video platform and player understands. Each cue has three parts: a sequence number, a timecode range in hours:minutes:seconds,milliseconds form (00:00:01,000 --> 00:00:04,200), and one or two lines of text, followed by a blank line. Because it is plain text you can open it in any text editor, but hand-writing the timecodes is slow and error-prone, which is exactly the part an SRT generator automates.
How accurate is the automatic transcription?
Clear speech with modest background noise transcribes very well, and word-level timing keeps each cue anchored to the moment it was spoken. Accuracy dips with heavy crosstalk, strong accents or niche jargon, which is why the workflow puts an editing pass between transcription and download. Skim the cue rows, hit play on anything doubtful and fix the text in place. Whatever you correct is exactly what the SRT contains.
Can I edit the subtitles before downloading the SRT?
Yes, and you should. Every cue appears as an editable row with a play button, so you can audition the audio behind a line and correct it in place. Timing is adjustable too: nudge a cue's start or end in 0.1 second increments, or set an edge to the current playhead position for tight sync. There is also a per-word emphasis editor if you plan to burn styled captions into the video instead of shipping a sidecar file.
Should I use SRT or VTT, and when do I need each?
Use SRT for uploads to platforms like YouTube and for most desktop players; it is the older, most widely accepted format. Use VTT (WebVTT) for HTML5 web players and native browser video, where it is the expected format and supports web-specific styling hooks. EchoWave downloads both from the same transcript, so you are never locked into one. If you already have a file in the wrong format, the subtitle converter switches between them without touching your timing.
Can I make subtitles for a video with no usable audio?
Yes. Auto-transcription needs speech, but the manual path does not: type or paste your lines as cues, then time each one against the playhead while you watch the footage. This is the right route for silent screen recordings, music-only clips, or footage where the audio is too rough to transcribe. The finished cue track downloads as a normal SRT, identical in structure to an auto-generated one.
What languages does the SRT generator support?
Transcription covers 50+ languages with automatic source-language detection, plus a manual override when detection needs help. After transcribing you can translate the cue track into 80+ languages with the subtitle translator and download a separate SRT per language, which is how one video ships with English, Spanish and Japanese subtitle files. Right-to-left scripts like Arabic are handled correctly, and Thai and CJK text splits on real word boundaries rather than mid-word.
Is the SRT generator free?
Generating, editing and downloading subtitle files is free to start. Subtitle downloads are sidecar text files, so the free plan's video watermark does not apply to them; the small watermark and 720p cap only matter if you also export the video itself with captions burned in. Paid plans remove the watermark and raise video export resolution to 4K and beyond on the top tier.
