LinkedIn video ads: specs, examples, and a LinkedIn video ad maker

The short answer

LinkedIn video ads run in a professional feed that mostly plays on mute, so the message has to read on screen. LinkedIn Campaign Manager accepts MP4 (H.264), 75KB to 500MB, from 3 seconds to 30 minutes, in landscape 16:9, square 1:1, or vertical 4:5 and 9:16, and 15 to 30 seconds is the length that performs (specs checked July 2026). AdsGen builds ads to that shape from a product or landing-page URL, casts an AI presenter who reads as a real person, and burns in captions so the ad still lands with the sound off.

Last updated July 2026

LinkedIn is the one feed where your buyer is already in work mode, which is why it is worth the higher click cost for B2B software, services, and recruiting. The problem is supply: briefing a creator to talk about a niche B2B workflow is slow and expensive, so most advertisers reuse one video until it fatigues.

AdsGen fixes the supply side. Paste your URL and get several captioned, feed-native video ads, each with its own angle and hook, sized to LinkedIn's specs. You can test which message lands with which job title instead of betting a whole quarter on a single edit.

What you get

LinkedIn video ads sized and captioned for a B2B feed

Built for a sound-off feed

Captions are burned into every ad and the hook is written to be read, not heard. Most of LinkedIn watches on mute, so on-screen text is the difference between a stop and a scroll.

The specs LinkedIn accepts

Ads render in the ratios Campaign Manager supports, 16:9, 1:1, 4:5, and 9:16, at the 15 to 30 second length LinkedIn recommends, so you upload without re-cropping or re-encoding.

Angles written for a job title

Scripts name a specific role and the workflow problem it owns, which is what makes a B2B viewer feel the ad is about them rather than a generic pitch to everyone.

What it handles

From a product URL to spec-ready LinkedIn ads

You pick the angles, creators, and tone. AdsGen writes the hooks, casts the creators, and renders native vertical ads with captions.

Good questions

Questions about LinkedIn video ads

LinkedIn Campaign Manager accepts MP4 encoded in H.264, from 75KB up to 500MB, and video length from 3 seconds to 30 minutes. Supported aspect ratios are landscape 16:9, square 1:1, and vertical 4:5 and 9:16, with resolution from 720p up (1080p recommended) and frame rates up to 30fps. Fifteen to thirty seconds is the length LinkedIn recommends for most objectives. Verify the current numbers in Campaign Manager before you build, since platforms revise specs.

Fifteen to thirty seconds for most campaigns. LinkedIn allows anything from 3 seconds to 30 minutes, but a professional feed rewards a short clip that makes one point. Awareness ads can run 15 seconds, consideration content 30 to 90 seconds, and only genuine thought-leadership video earns the two to five minute range with an already-engaged audience. Put the hook and the on-screen text in the first three seconds either way.

They autoplay muted. Video starts playing as the ad scrolls into view, but sound only turns on if the member taps or has enabled it, and most do not. That is why captions are not optional on LinkedIn: an ad that depends on a voiceover to make its point will lose most of its audience. AdsGen burns captions into every ad so the message reads whether the sound is on or off.
