Captions for LinkedIn Videos That Play on Mute

Not always. If you speak one of the 10 languages LinkedIn auto-captions and plain captions are fine, LinkedIn’s free auto captions may be enough: switch on “Review captions before viewers can see them” and fix names and jargon before they go live. LinkedIn says some videos autoplay without sound in the feed, so captions of some kind are worth having on every talking video.

Burned-in captions are worth the extra step when you want them in your brand’s fonts and colors, when you post in a language LinkedIn doesn’t auto-caption, when you post the same video to Instagram, TikTok or YouTube too, or when you want keywords highlighted as you say them. They also appear the moment the post goes live, while LinkedIn’s captions can take a while to be generated.

If you burn captions in, switch LinkedIn’s “Add auto captions” toggle off when you post, so viewers don’t get your captions and LinkedIn’s on top of each other.

LinkedIn accepts any aspect ratio from 1:2.4 (tall) to 2.4:1 (wide), so 9:16, 4:5, 1:1 and 16:9 all upload. On a phone, LinkedIn also has a full-screen vertical video player (not yet available to every member); its help center says videos with a larger aspect ratio may be cropped on the sides and at the top and bottom there, and wider ones may be fitted to the screen. You can’t post directly to that vertical feed: any video you post may appear in it based on relevance and performance.

A practical rule: if you filmed vertically on your phone, export 4:5 or 9:16. If you recorded a webinar, a Zoom call or a desk setup in 16:9, keep 16:9 or crop to 1:1. StoryCut exports all four formats, and changing the format crops the frame to fill it, so leave some room around your head and shoulders when you film.

For length, LinkedIn allows up to 15 minutes. StoryCut handles videos up to 4 minutes on Free, 7 on Starter, 10 on Pro and 30 on Business, so a 12-minute talk needs Business. A 1080p export, on Starter and up, fits well inside LinkedIn’s limits.
