Video Captions for Marketers
Paid social and organic feeds both autoplay muted, so a caption track is not an accessibility afterthought on campaign video — it is the difference between a hook that lands and three wasted seconds of impression.
Caption Maker generates them in about 30 seconds per clip, which is fast enough to caption every variant in a test rather than just the hero cut.

Why marketers teams caption
The parts of captioning that matter most for this kind of video.
Caption every variant, not just the hero
When captioning takes seconds, every cut in a test gets the same treatment. You stop comparing a captioned hero against uncaptioned variants and calling it a result.
Hook-length lines
Feed captions work at three or four words a line, not broadcast-length subtitles. Line splitting defaults to the short, fast rhythm that short-form actually uses.
On-brand by default
Set font, colour, outline and placement once and reuse it, so captions look like part of the creative rather than something bolted on afterwards.
Transcripts for the whole funnel
Export the transcript and reuse it as ad copy, a blog post, email subject lines or SEO body text. One shoot, several assets.
How it works
Upload, review, export. No timeline and no timecodes typed by hand.
- 1
Upload your video
Drop in your marketers footage as MP4, MOV, MKV or an audio file. Nothing to install, and no account needed to start.
- 2
Generate captions with AI
The AI transcribes the audio and cuts it into short, punchy caption lines — the length that reads cleanly in a feed rather than long broadcast-style subtitles.
- 3
Edit and export
Correct the terms specific to marketers, then download the video with captions burned in, or export a clean .srt or .vtt file.
Captions as a performance lever, not a compliance box
Most teams first add captions because someone raised accessibility, which is a good reason. But the reason captions stay in the workflow is that they move the numbers on paid and organic social, and they do it for a reason that is easy to state: the platform plays your video with the sound off.
That single fact reframes the creative brief. Your hook is not the first line of the voiceover — it is the first line of text on screen. If there is no text, the hook is whatever the opening frame happens to show, which is rarely what you would have chosen.
The practical constraint has always been throughput. A campaign is not one video, it is a hero cut plus a dozen variants across placements and audiences, and captioning all of them by hand is not something a team ships on a deadline. Generating them per clip in seconds is what makes captioning a default rather than something the hero cut gets and nothing else does.

Frequently Asked Questions
Specific to this kind of video, not the generic list.
Do captions actually improve video performance?
They address a specific, measurable problem: social video autoplays muted, so an uncaptioned video communicates nothing in the first seconds when viewers decide whether to stay. Whether that shows up as completion rate or view-through depends on your creative, which is why captioning every variant rather than just the hero is worth doing.
Can I keep captions consistent across a campaign?
Yes. Caption styling — font, weight, colour, outline, position — is set per export, so once you have a look that matches the campaign you apply it to every cut.
Should I burn captions in or upload a subtitle file for ads?
Burn them in for paid social. Ad placements generally have no captions toggle, and burned-in text renders identically everywhere. Keep the .srt as well for organic YouTube uploads, where a separate file is better for search.
Can I reuse the transcript for other channels?
Yes, and it is one of the more underrated wins. Export the transcript and it becomes the raw material for ad copy, a blog post, email content or a landing page section.
Can I edit my captions before exporting?
Yes. Correct the transcript, adjust timings, choose a caption style and then export the finished video or a clean SRT or VTT file.
