LinkedIn video for B2B founders: specs, captions and a clip map from your podcasts and talks
Updated 26 October 2026 · Written by Reyansh Juneja and Naman Dhiman, the co-founders of SOVE7GN, who run the campaigns and review the clips
LinkedIn video works for B2B founders when each post is a clip of you making one clear argument, 30 to 90 seconds long, captioned, with a few lines of text above it that say why it matters to a buyer. The source is almost always something you already recorded: a podcast appearance, a conference talk, a webinar or a sales call you are allowed to use.
Short answer: LinkedIn accepts video from 3 seconds (2 on mobile) to 15 minutes, up to 5 GB, in any aspect ratio from 1:2.4 to 2.4:1, so a 9:16 vertical clip works. Burn captions in or upload an SRT file on desktop. Cut one hour of talk into 12 to 20 clips, post one on LinkedIn each weekday, and send the rest to Shorts, Reels and X.
What are LinkedIn's video specs?
All from LinkedIn's own video sharing help page, checked October 2026:
| Spec | Limit |
|---|---|
| Length | 3 seconds minimum from desktop, 2 seconds from the mobile app; 15 minutes maximum |
| File size | 75 KB to 5 GB |
| Aspect ratio | 1:2.4 to 2.4:1 |
| Frame rate | 10 to 60 fps |
| Resolution | 256 x 144 to 4096 x 2304 |
| Formats | MP4, MOV, AVI, WEBM, MKV, WMV and others |
The 1:2.4 to 2.4:1 range covers vertical 9:16 (1:1.78), square 1:1 and horizontal 16:9, so the same vertical export you make for Reels and Shorts posts to LinkedIn unchanged. All platforms side by side are on our clip specs by platform page.
How do you add captions to a LinkedIn video?
LinkedIn's closed captions help page says you can add captions when you share a video using the desktop experience, and that the video must have an SRT (SubRip Subtitle) file attached before it can be posted with them.
Our advice: burn captions into the video itself as well. Burned-in captions show on every device and every app, survive reshares and do not depend on the upload flow. Keep them in the middle of the frame, two lines at most, so they are not hidden by the post text or buttons. Our guide to captioning clips covers styles.
How is LinkedIn different from Reels for B2B buyers?
This is our judgment from posting founder clips on both, not platform data:
| Instagram Reels and YouTube Shorts | ||
|---|---|---|
| Who is watching | People at work: buyers, peers, hires, investors | Anyone, mostly off the clock |
| What makes them stop | A claim about their job or market | A hook in the first second or two |
| The text around the clip | Carries a lot: 2 to 5 lines framing the argument | A short caption; the video does the work |
| Best clip type | An opinion, a number, a story with a lesson | Fast, visual, emotional moments |
| Ideal length | 30 to 90 seconds | 15 to 60 seconds |
| Who the post is from | Your personal profile usually beats a company page for founder clips | Your main account |
The biggest difference is the post text. On Reels, the caption is an afterthought. On LinkedIn, the 2 to 5 lines above the video are often what earns the play, so write them like the opening of an argument, not a summary.
How do you turn a podcast or talk into LinkedIn clips?
One hour of talk-heavy video usually gives 12 to 20 clips. For a B2B founder, these eight types carry most of the value; find them in the transcript first, then cut.
| # | Clip type | What to look for | Example first line |
|---|---|---|---|
| 1 | The contrarian claim | Where you disagreed with the host or the market | "Most companies hire a head of sales too early." |
| 2 | The number | A figure from your own business you can stand behind | "We cut onboarding from [X] weeks to [Y] days." |
| 3 | The story | A specific customer or deal moment, anonymized | "A customer called on a Friday to cancel." |
| 4 | The steps | Any answer that starts "first, we..." | "How we run a pricing change in three steps." |
| 5 | The objection | Your answer to the thing buyers push back on | "People ask why we don't offer a free trial." |
| 6 | The mistake | What you got wrong and what changed | "The worst hire I made, and the question I now ask." |
| 7 | The customer question | A question your prospects ask in every call | "Do we need to replace our CRM for this?" |
| 8 | The prediction | Where your market is going | "In two years, nobody will buy this as a seat license." |
Only use numbers you can back; a clip lives a long time. If you clip a podcast you appeared on but do not own, get the show's permission first. Our clipping for founders page covers that, and the SaaS version covers webinars and demos.
How often should a founder post video on LinkedIn?
Our position: one clip each weekday on LinkedIn is plenty, and it uses 5 of the 12 to 20 clips an hour of recording gives. The rest go to YouTube Shorts, Reels and X, where volume matters more. On our Growth plan, 4 clips a day split across platforms covers both.
| Recording a week | Clips (12 to 20 per hour) | Other platforms | |
|---|---|---|---|
| 1 hour (one podcast or webinar) | 12 to 20 | 5 | 7 to 15 |
| 2 hours | 24 to 40 | 5 to 10 | 14 to 35 |
Reply to comments in the first hours after posting. On LinkedIn, the conversation under a clip is where buyers raise their hand.
Who posts the clips: you, your company page or a network?
Founder clips usually belong on your personal profile, because buyers follow people (our founder-led content examples show the same clips working beyond LinkedIn). A company page is the place for product clips and team content. LinkedIn lets a page super admin add a content admin, who can "create and manage Page content" (LinkedIn Help), so an editor can post there without anyone sharing a password.
Clipper networks mostly skip LinkedIn. ClipUp, for one, lists TikTok, Instagram Reels, YouTube Shorts and X as its platforms (ClipUp). Our CPM network covers 7 platforms, LinkedIn included. For a B2B founder, though, own accounts usually come first; our comparison of own accounts vs a clipper network explains why. If you are in a regulated field such as financial advice, read our FINRA and SEC rules for advisor videos before any clip posts.
On a retainer, we cut your podcasts, talks and webinars into clips and post them on the accounts you give us access to, LinkedIn included. You approve 2 example clips first, and we are live within 48 hours. Entry is $2,000 a month for 2 clips a day; Growth is $4,000 for 4.

Questions people ask
How long can a LinkedIn video be?
Up to 15 minutes for a video shared in a post, according to LinkedIn's help page, with a minimum of 3 seconds from desktop and 2 seconds from the mobile app. For founder clips, 30 to 90 seconds is what we recommend.
What size should a LinkedIn vertical video be?
Export at 1080 x 1920 (9:16). LinkedIn accepts aspect ratios from 1:2.4 to 2.4:1 and resolutions up to 4096 x 2304, so a standard vertical export for Reels or Shorts works without changes.
How do you add captions or subtitles to a LinkedIn video?
On desktop, attach an SRT file when you share the video, as LinkedIn's help page describes. We also burn captions into the video so they show everywhere, including in reshares.
What is the best time to post video on LinkedIn?
There is no single answer that holds for every audience. Post when your buyers are at work in their time zone, keep the slot consistent for a month, and compare results in your post analytics before changing it.
