Caption Generator

Caption generator

Auto-caption your video, then style every line.

Upload a video and VidMints transcribes the spoken audio into timed captions automatically, so you skip typing and syncing every line by hand. From there you edit the wording, adjust the timing, style the look and either burn the captions into the video or export them as an SRT file. Because most social video is watched on mute, captions are often the difference between someone watching and scrolling past — and this turns a tedious job into a few minutes of review. It works for Reels, Shorts, TikTok, YouTube and any clip where clear on-screen text keeps viewers watching.

What is Caption generator?

A caption generator does the slowest part of subtitling for you: it listens to the audio track of your video and produces text lines that are already timed to the speech. Captioning by hand means typing every sentence, then dragging each line so it appears and disappears exactly when the words are spoken — a job that can take longer than editing the video itself. Automatic transcription hands you that entire first draft in one pass, turning hours of manual syncing into a few minutes of review.

In VidMints that draft is the beginning, not the end. Once the captions are generated you can correct any misheard words, split a long line into two so it fits the screen, merge fragments, and nudge the timing until each caption lands precisely with the speech. You then control how the captions look — the font, size, color and where they sit in the frame — so they match your brand and stay legible on whatever platform you are posting to. Nothing is locked; the automatic pass simply removes the tedium.

When the captions are ready there are two ways to ship them, and they serve different needs. You can burn them in, baking the styled text permanently into the video pixels so they always display, which is what muted in-feed social requires. Or you can export a standalone SRT file that a player toggles on and off, which suits YouTube and viewers who rely on accessibility settings. Choosing the right one for each destination is part of getting captions to actually do their job.

Why use Caption generator?

The blunt reason captions matter is that most social video is watched with the sound off. A viewer scrolling a feed on a train or in an open office will not turn the volume up for an unknown clip — they will keep scrolling unless the on-screen text tells them what is happening. Captions capture that silent majority, and they measurably improve watch time and completion because they make every video easier to follow.

There is an accessibility and reach angle too: captions open your content to deaf and hard-of-hearing viewers and to anyone watching in a second language, while automating the work means you can caption everything you publish instead of only the videos you have time to subtitle by hand.

What you can do

Auto transcription

Generate timed captions straight from your video's audio — the first full draft appears without any typing.

Edit text and timing

Fix wording, split or merge lines and nudge timing so each caption lands exactly with the speech.

Styled captions

Control font, size, color and position so captions match your brand and read well on any feed.

Burn in or export SRT

Bake styled captions into the video for social, or export a clean SRT file to use elsewhere.

Higher watch time

Captions keep mute viewers watching and make videos easier to follow, which lifts completion rates.

Who it's for & example uses

Muted-feed social clips

Burn styled captions into Reels, Shorts and TikToks so the message lands even when the sound is off, which is how the vast majority of feed video is watched.

Long-form YouTube uploads

Export a clean SRT file to upload alongside a YouTube video, giving viewers toggleable subtitles and helping the platform index what the video is about.

Repurposing across platforms

Caption one recording once, then burn in for social and export SRT for YouTube, so a single edit serves several destinations without redoing the work.

Tips for the best results

Always read the auto-transcribed draft against the audio before publishing; names, jargon and homophones are where automatic transcription most often slips.
Keep each caption to a short line or two — long blocks of text cover the frame and are harder to read at a glance than tight, punchy lines.
Style for legibility first: high-contrast text with a subtle background or outline stays readable over busy footage far better than plain type.
Position captions clear of platform UI, keeping them out of the lower zone where Reels and TikTok stack buttons and usernames.
Burn captions in for in-feed social where they must always show, and export SRT for YouTube where viewers can toggle subtitles themselves.

Frequently asked questions

How does the caption generator work?

Upload a video and VidMints transcribes its audio into timed captions automatically. You then review the text, adjust timing and style the captions before burning them in or exporting an SRT.

Can I edit the auto-generated captions?

Yes. Auto-transcription gives you a first draft, and you can fix wording, split or merge lines, and shift timing so each caption syncs precisely to the speech.

Can I download an SRT file?

Yes. You can export your captions as an SRT file to use on YouTube, other editors or platforms that read a separate subtitle track.

Can I style the captions?

Yes — adjust font, size, color and on-screen position so the captions match your brand and read clearly on the platform you're posting to.

What's the difference between burned-in captions and SRT?

Burned-in captions are baked into the video pixels and always show — which is what in-feed social needs. An SRT is a separate file the player toggles on, better for YouTube and accessibility settings.

Is the caption generator free?

You can start for free and new accounts get credits to try it. Auto-transcription uses credits per run, while editing and styling captions in the studio is part of the workflow.
