Add captions to a video, without opening an editor

What you get

• Your video with burned-in captions that highlight the word being spoken (open captions, visible everywhere)
• An .srt file of the same text, for platforms that take uploaded subtitles (closed captions)
• Nothing cut: with the Captions only brief, the footage is untouched
• Your original resolution, up to 4K

How to ask

Upload on the home page and write: Do not cut anything. Add accurate captions and give me an .srt file. Add anything that matters: a brand color, bold or plain, how many words per line, spellings of names. You can also combine captions with cuts: remove the ums, add captions.

Open vs closed captions

You get both, so you can use whichever suits the platform.

Accuracy

Captions come from a transcript with word timings, so they follow the speech closely. Clear speech comes out well; noisy audio, crosstalk and heavy accents lower accuracy. Tell us the spelling of names, brands and jargon, and use your two rounds of changes to fix anything that remains. Captions are in the language spoken; we do not translate them.

When a free tool is enough

YouTube, Instagram and TikTok have built-in auto-captions, and self-serve tools like Kapwing, VEED and Descript offer editors. If you have one short clip and want to restyle every word yourself, use those. If you have a stack of videos and want finished files with a consistent look, you save time here.

Limits

• Captions are bold with word highlighting. A fully custom animated caption design is not something we promise
• No translation or dubbing
• Silent footage has no speech to caption

Price

One video is one of your monthly videos: $39 for 10 or $149 for 50. See pricing.

Worked example: a 6-minute talking-head video

You upload a 6-minute MP4 and write: Do not cut anything. Add accurate captions and give me an .srt file. Brand name is Flowdesk. You receive the same 6-minute video with captions burned in, with the word being spoken highlighted, and a separate .srt file with the same text and timing. You post the burned-in version on Reels and TikTok and upload the .srt to YouTube so viewers can switch captions on, and so the text can be indexed. This is one video of your monthly quota.

Why captions matter

Many people watch short video without sound, in public or at work, and captions let them follow it. Captions also help viewers with hearing loss and non-native speakers. Burned-in captions guarantee that the words are visible on every platform; an .srt file lets viewers turn captions on and off on platforms that support it. We make both from the same transcript so they match.

Checklist before you upload

1. Decide whether you want captions only or captions plus cuts.
2. List names, brand terms and unusual words.
3. Say where you will publish, and mention any caption look you want (bold, plain, brand color) so it can be taken into account.
4. Upload the original file, up to 4 GB.

If you only have a video with no speech, there is nothing to caption.
