How accurate is the subtitle timing?

Cue timing comes from silence-aligned speech chunks, which keeps subtitles in sync with the dialog for normal viewing. It is not word-level karaoke timing, so if you need frame-perfect cues you can fine-tune the SRT in your editor afterwards.

Does it add speaker labels?

No. Cues hold the spoken words shaped into standard two-line blocks of up to 42 characters per line, with no speaker names.

What if I need a VTT file instead?

Use the Video to VTT tool for a WebVTT file, or the Subtitle Generator to get SRT, VTT, and a plain-text transcript from one upload.

How is pricing calculated?

Subtitling is 5 credits per minute of audio. Because the length is not known until the file is processed, the upfront hold is estimated from file size at a typical video bitrate (about 8 MB per minute), so a typical minute works out to about 5 credits. The minimum is 5 credits.

Yes. Videos run on our own servers, are never used to train any model, and are auto-deleted 7 days after the job finishes.

Who uses this tool

VIDEO PRODUCTION

A caption track for the timeline

Import the SRT into Premiere, Resolve, or Final Cut and adjust cues on the timeline instead of typing them from scratch.

YOUTUBE & VIMEO

Caption uploads without the wait

Upload the SRT next to your video so viewers get proper captions instead of auto-generated guesses.

SOCIAL MEDIA

Clips that work with the sound off

Most feeds autoplay on mute. An SRT gives your clip subtitles so the message still lands.

EDUCATION

Captioned lectures and tutorials

Turn recorded lessons into captioned videos students can follow in quiet spaces or a second language.

LOCALIZATION

A source file for translators

Hand translators a timed SRT of the original dialog so they translate cues instead of transcribing from scratch.

CORPORATE COMMS

Town halls and training, captioned

Caption internal recordings so people can catch up from a desk, a train, or an open-plan office.

SECURITY

Built for sensitive documents

Bank statements, medical files, case records. Security isn't a feature we added — it's the foundation.

Questions

MP4, MOV, M4V, WEBM, MKV, or AVI, one video per job, up to 500 MB and about 60 minutes of audio — longer recordings are rejected up front with a clear message. We extract the audio track and transcribe the speech; if the file has no audio or no recognizable speech, the job stops and tells you.
