Captions that match
where the video is going.

Muted autoplay is the default on every social feed, which means captions are frequently the only channel your message has for the first several seconds. This is not a style preference. It is the difference between a video that communicates and one that scrolls past.

The behavioural data backs it up: 63% of consumers would most like to learn about a product by watching a short video, and much of that browsing happens sound-off in public. Meanwhile marketers rank short-form video as their top format for return on investment: a format built to be watched silently, at speed, on a phone.

There is an accessibility argument too, and it is the stronger one. Captions are how deaf and hard-of-hearing viewers use your video at all. Treating them as a growth tactic undersells them.

Applying one caption style everywhere is the most common mistake, and it is visible immediately.

TikTok and Reels

Large, centre-weighted, high contrast, often word-by-word or in short phrase groups that appear in rhythm with the speech. They are part of the visual design rather than an accessibility layer bolted on. Keep them clear of the bottom third, where the platform's own UI sits.

YouTube long-form

Quieter and more traditional. Bottom-anchored, modest size, full phrases rather than single words. Viewers are settled in and watching for minutes, so captions that flash and jump become exhausting. Legibility beats flash.

LinkedIn and embedded video

Conservative. Clean sans-serif, bottom-third, no animation. The context is professional and the audience is often skimming in a feed at desk width rather than on a phone.

You can just say where it is going ("this is for LinkedIn"), and get the appropriate treatment rather than configuring each property.

Automatic transcription is very good and still not perfect, and the errors cluster predictably: proper nouns, product names, industry jargon, and acronyms. Those are also the words that matter most in a business video.

The fix is to say them. "The product is called Blob, with a B" or "spell it Kubernetes throughout" corrects every instance at once, rather than hunting through a caption track. If a whole passage is wrong, ask for that section to be re-transcribed.

It is worth a pass before publishing. A caption that misspells your own product name in front of every muted viewer is worse than no caption.

Blob burns captions into the picture. That means they are guaranteed to appear, styled exactly as you designed them, on every platform and every player, with nothing to upload separately and nothing a platform can restyle or drop. For social video that is exactly what you want.

For a long-form YouTube upload, pair that with YouTube's own automatic captions. YouTube generates a toggleable caption track from your audio, which viewers can switch on and off and which YouTube can read. A common setup: clean burned-in captions on the Shorts and social cuts, and YouTube's track on the long version.
