Audio and video to SRT

Generate SRT subtitles from audio or video

Upload a recording or paste a supported public link, turn the speech into editable timestamped text, then download a standard SRT subtitle file.

Supports common audio and video formats. Transcription is charged by started minute.

Simple workflow

Create an SRT file in three steps

  1. 01

    Upload an audio or video file, or paste a supported public URL.

  2. 02

    Transcribe the speech and correct the timestamped text.

  3. 03

    Download the finished transcript as a standard .srt subtitle file.

Turn speech into timed subtitle cues

CastToAny creates timed subtitle cues from the recording. Correct the text before export, then download SRT, VTT or a plain TXT transcript.

Good content starts with a clear idea, but the useful details often live inside the recording.

Speaker 1

A timestamped transcript makes every quote searchable and keeps it connected to the original moment.

Review the wording, fix names, then export the transcript or turn it into the next piece of content.

How the SRT generator builds subtitle cues

An SRT file is a plain-text subtitle format made from numbered cues.

Each cue contains a start time, an end time and the words shown during that interval. The SRT generator creates those timed segments from speech in an uploaded recording or supported public link, then opens them in an editor before download. That review step matters because subtitle timing and readable line breaks are just as important as recognizing the words.

Use the editor to correct names, punctuation and specialist vocabulary while the timestamps remain attached to each segment. When the subtitle file is ready, download SRT for broad compatibility, VTT for many browser-based players, or TXT when timing is not required. The original transcript remains in the project so you can make another correction without retranscribing the recording.

Prepare better subtitles before export

Automatic timing is a practical starting point, not a substitute for a final watch-through.

A reliable SRT generator still needs human review: keep each cue short enough to read, avoid splitting a name or phrase across cues, and check that a subtitle disappears before the next speaker begins. Music, overlapping dialogue and long pauses may need manual adjustment. If the recording will be published professionally, test the exported file in the target editor or player.

The SRT generator is designed for recordings you own or are allowed to process. Uploads use private object storage and the extraction worker removes temporary files after the job. Do not upload confidential conversations without the participants’ permission. Use the SRT generator with the linked guide when you need a detailed explanation of cue numbers, timecode syntax and manual editing before the final export.

SRT generator questions

Can I convert both audio and video to SRT?

Yes. You can upload common audio formats such as MP3, M4A and WAV, or video formats such as MP4, MOV and WebM.

Can I edit the subtitles before downloading?

Yes. Review and correct the timestamped transcript in your project before downloading the SRT file.

What is the difference between SRT and VTT?

Both contain timed captions. SRT is widely supported by video editors and players, while VTT is commonly used for captions in web video.
