Correction, 2026-10-02: the previous version said LinkedIn is "not a vertical-first feed" and told you to generate 16:9 and crop a square from it. LinkedIn's video ad specs mark vertical 4:5 as the recommended ratio, and its mobile app opens feed videos in a full-screen vertical player; the shape advice now follows LinkedIn's pages, says how to get a 4:5 version (no 8frame video model generates 4:5, so crop it from 9:16) and names the models that make 1:1 from text (Veo 3.1 does not). It said switching sound off halves the Veo price on both tiers: that holds for Standard (448 to 224), while Fast drops from 168 to 112, a third less. It also stated things we have not measured or sourced: that LinkedIn's audience is "professionally invested in spotting fakery", that AI filler "costs more" there, that "your network can tell", that LinkedIn video "clusters into three patterns", a 20 to 40 second length for talking heads, that Act Two "keeps the speaker's own delivery", and that running several models from one canvas "beats" subscribing to one. Those are now advice or removed. Every LinkedIn spec was re-checked on LinkedIn's own pages on 2026-10-02, and the page now notes where two LinkedIn pages disagree on frame rate.
Correction, 2026-10-01: the pricing table still said a Starter plan covers about eight Veo 3.1 clips (it covers two) and six Veo 3.1 Fast clips (five), and listed Wan 2.5 at about $0.10 and 15 clips (102 credits is about $1.02, nine clips; the table now shows Wan 3.0, the Wan default, at 95). The sample month we said fits inside Starter came to 1,012 credits before the talking head was even counted; the corrected math is below. Kling 2.6 Pro's 47 credits is the silent 5-second price (95 with sound), ElevenLabs TTS bills 13 credits per started 1,000 characters, and Veo 3.1 Fast costs about three-eighths of Standard, not half. LinkedIn format claims now come from LinkedIn's own help pages, and we removed quality claims we have not measured.
Correction, 2026-09-30: we said the $19 Starter plan covers about eight full Veo 3.1 clips a month. At 448 credits each it covers two. Fixed.
The best ai video for linkedin in 2026 isn't one model, it's a three-model bench: Veo 3.1 for the clip that stands for your brand, Kling 2.6 Pro for the b-roll that fills the middle of a post, and OmniHuman or Runway Act Two when a talking head does the talking. They do different jobs at very different prices, from 47 credits for a silent 5-second Kling clip to 672 for a 30-second OmniHuman update. LinkedIn also has its own rules: it recommends 4:5 for video ads, feed videos may autoplay without sound, and your posts go out under your professional name. Model choice here is less about spectacle and more about not embarrassing the person whose name sits above the post.
TL;DR
- The clip that stands for the company: Veo 3.1 Standard at 448 credits for 8 seconds with sound (224 silent); try the shot on Veo 3.1 Fast (168) first
- Budget b-roll: Kling 2.6 Pro at 47 credits for a silent 5-second clip, about $0.47 at pack rate, for office, product and process shots
- Talking heads: OmniHuman to animate a founder photo with an audio track, Runway Act Two to retarget a real recorded performance
- Shape and length: LinkedIn's video ad specs mark 4:5 as the recommended ratio and recommend 15 to 30 seconds. No 8frame video model makes 4:5, so generate 9:16 and crop; for square, Kling 2.6 Pro and Wan 3.0 make 1:1 from text, Veo 3.1 does not
- Captions on screen: feed videos may autoplay without sound, and LinkedIn's own video ad tips suggest subtitles
Three LinkedIn facts that shape the generation
It takes almost any shape, and recommends 4:5 for ads. LinkedIn's help center accepts shared video from 1:2.4 to 2.4:1. Its video ad specs list 16:9, 1:1, 4:5 and 9:16 and mark vertical 4:5 as the recommended ratio. In the mobile app, tapping a video in the feed opens a full-screen vertical player (LinkedIn notes it may not be available to all members yet), and wider videos may be fitted to the screen. No video model on 8frame generates 4:5, so generate 9:16 and crop: a 1080p 9:16 clip is 1080 pixels wide, and a 4:5 crop of it is 1080 x 1350, the largest 4:5 size LinkedIn's ad specs list. Keep the subject and any on-screen text near the middle of the frame so the crop does not cut them. For a square version, Kling 2.6 Pro and Wan 3.0 generate 1:1 from text; Veo 3.1 makes 16:9 and 9:16 only. The shapes for every model are in AI video aspect ratios by model.
Autoplay can be silent. LinkedIn's own help page says some videos "may play automatically without sound as you scroll through your feed", and members can switch autoplay off. Treat every clip as silent until someone taps: write the on-screen text first and let the footage illustrate it. LinkedIn's video ad tips suggest adding subtitles and showing the most impactful content in the first 10 seconds, and its ad specs accept captions as an SRT file (text only). Its help center also asks you to keep the edges of the frame (top, bottom and sides) free of key elements, text and logos, so the interface does not cover them.
The audience knows you. Your posts land in front of colleagues, clients and people who have met you. A malformed hand in a handshake shot is the kind of detail people point out in comments, and on LinkedIn those comments sit under your professional name. Check hands, faces and any text in the frame before you post.
The specs that matter
From LinkedIn's pages, checked 2026-10-02:
- Shared video (posts): MP4 among many accepted formats (MOV, AVI, WEBM and MKV among them), 75 KB to 5 GB, 3 seconds (2 from the mobile app) to 15 minutes, 256 x 144 to 4096 x 2304, aspect ratio 1:2.4 to 2.4:1, 10 to 60 fps, 192 Kbps to 30 Mbps
- Video ads: MP4 (H.264 or VP8), 75 KB to 500 MB, 3 seconds to 30 minutes, with 15 to 30 seconds recommended "so they can qualify for all possible placements"; 4:5 marked as the recommended ratio (720 x 900 recommended, up to 1080 x 1350), 16:9 (1920 x 1080 or 1200 x 675 recommended), 1:1 (up to 1920 x 1920) and 9:16 (720 x 1280 recommended, up to 1080 x 1920); less than 30 fps; captions as SRT. Ads under 30 seconds loop until there are at least 30 seconds of playback
- Frame rate, where LinkedIn disagrees with itself: the ads guide on LinkedIn's business site lists a recommended frame rate of 30 fps, while the help center's ad specs ask for less than 30
The video models we have measured on 8frame (Kling, Seedance, Hailuo and Gemini Omni Flash among them) return H.264 MP4 at 24 fps, inside the help center's frame-rate limits for both posts and ads. Bit rate is the one to watch: Kling 2.6 Pro's 1080p files run close to LinkedIn's 30 Mbps ceiling for shared video (the middle half of them spans 21.3 to 30.2 Mbps in our production files), so if an upload is refused, re-encode it at a lower bitrate. The full ad requirements are in LinkedIn video ad specs.
Three formats to plan for
Each of these formats maps to a different model.
The thought-leadership talking head. A person, a claim, captions doing the heavy lifting. See what is a talking head video for the anatomy.
The b-roll essay. A text hook in the post, video underneath as visual pacing: office scenes, product close-ups, process shots, data on screen. The video doesn't argue, it keeps the reader inside the post while the caption argues.
The product explainer. A 15 to 30 second demo or feature clip (the length LinkedIn recommends for video ads), usually the one you spend the most on, because it stands in for the product itself. The playbook overlaps heavily with AI for B2B marketing.
Veo 3.1: the clip that stands for the company
At 448 credits per 8-second generation with sound, Veo 3.1 Standard is the most expensive option on this page per second, so reserve it for the clip that represents the company. We have not measured it against the other models here, so test the shot on Veo 3.1 Fast first: the Veo tool opens on Fast (168), and Standard is a deliberate switch. On 8frame Veo 3.1 renders at 1080p in 16:9 or 9:16, so a 4:5 or square version is a crop. Veo generates sound with the picture, which helps launch teasers and brand moments, but on a feed that may autoplay silently you can switch sound off: Standard drops to 224 (half) and Fast to 112 (a third less). The prompt patterns in Veo 3.1 prompts for brand films apply to LinkedIn brand clips; keep the shots shorter and the message single.
On the $19 Starter plan (1,000 credits), 448 credits per clip means two full Standard generations with sound a month. A hero clip a week, four a month, is 1,792 credits, which needs the $49 Creator plan (3,000 credits). Veo 3.1 Fast at 168 credits costs three-eighths of the Standard price.
Kling 2.6 Pro: the b-roll workhorse
In the b-roll essay most of the footage is connective tissue, and paying Veo rates for connective tissue adds up fast. Kling 2.6 Pro costs 47 credits for a silent 5-second clip (about $0.47 at pack rate, 21 clips on Starter) and covers that format: a hand annotating a document, a warehouse pan, a screen filling with a dashboard. From text it makes 16:9, 9:16 or 1:1, so a square version does not have to be a crop. The Kling tool opens on Kling v3 Standard with sound (86), which needs a start image, so pick 2.6 Pro and switch sound off to get 47; with sound it is 95. Generate three variants per slot and keep the cleanest, and a slot costs 141 credits, about $1.41.
OmniHuman and Act Two: the talking heads
Talking heads are where LinkedIn AI video gets sensitive, because the face on screen may be a real person on the team.
Two routes exist on the 8frame canvas. OmniHuman animates a single photo with an audio track into a speaking clip, so a founder headshot plus a voice becomes a talking update. It costs 22.4 credits per second of audio, billed in 5-second steps up to 35 seconds: 112 for 5 seconds, 672 for 30. Pair it with ElevenLabs TTS (13 credits per started 1,000 characters, so a script of up to 1,000 characters is 13) or the founder's own recorded voice. Runway Act Two goes the other direction: record a real performance on a phone, then retarget it onto a styled character or a cleaner setting. It bills 8 credits per second of the reference video, 3 to 30 seconds, so a 30-second update is 240. The performance comes from a real recording rather than from a script.
A cheaper photo-plus-audio option is Pruna Avatar, 17 credits for 5 seconds at 720p and 102 for 30 seconds (up to 35). It is new on 8frame, so judge it on your own test clip before you rely on it.
Use these for scale problems (localizing one founder update into five languages) rather than for pretending someone said something they didn't record. Disclose when it matters: the comment section is public.
Avoiding obvious AI filler
Under your professional name, a comment pointing out obvious AI filler is the outcome to avoid. Generic drone-over-city openers, uncanny stock-human smiles and caption bait with nothing underneath are the usual suspects. The fixes are simple. Keep clips short and specific to your actual business. Put your claim on screen early (LinkedIn's own tip is to show the most impactful content in the first 10 seconds). Use AI for footage you could never shoot, not as a cheaper version of footage you should shoot. And never post a clip you wouldn't defend in the comments.
Pricing math
Current credit costs on 8frame, with pack rate at a cent per credit (top-up packs run $10 per 1,000).
| Model | Credits per clip | Cost at pack rate | Full clips on the $19 Starter | LinkedIn job |
|---|---|---|---|---|
| Veo 3.1 Standard, 8s with sound | 448 | ~$4.48 | 2 | Hero brand clips, product moments |
| Veo 3.1 Standard, 8s silent | 224 | ~$2.24 | 4 | Hero clips for a muted feed |
| Veo 3.1 Fast, 8s with sound | 168 | ~$1.68 | 5 | Brand clips at volume |
| Kling 2.6 Pro, 5s silent | 47 | ~$0.47 | 21 | B-roll, process shots |
| Wan 3.0, 5s at 1080p | 95 | ~$0.95 | 10 | Background footage under captions |
| Runway Act Two, 30s reference | 240 | ~$2.40 | 4 | Talking head from a real recording |
| OmniHuman, 30s of audio | 672 | ~$6.72 | 1 | Talking head from a photo |
A sample month of LinkedIn content is one hero clip, four b-roll batches of three Kling variants each, and one talking-head update. With a Veo 3.1 Standard hero with sound (448), the twelve Kling clips (564) and a 30-second Act Two update (240), that is 1,252 credits: more than Starter's 1,000, so it needs Creator or a top-up. Make the hero a Veo 3.1 Fast clip (168) and the same month is 972 credits, inside a single Starter plan, watermark-free. Swap Act Two for a 30-second OmniHuman update (672) and you are back on Creator. Unused credits roll over while you're subscribed.
FAQ
What's the best AI video generator for LinkedIn?
Veo 3.1 for the clips that stand for your brand, Kling 2.6 Pro for everyday b-roll at 47 credits per silent 5-second clip, and OmniHuman or Runway Act Two for talking-head formats. They cover different jobs at different prices. On 8frame all of them run on one canvas and draw on a single credit balance, from $19 a month.
What format should LinkedIn videos be?
LinkedIn accepts shared video from 1:2.4 to 2.4:1, 3 seconds to 15 minutes and up to 5 GB, so format is your choice rather than the platform's. For video ads it marks 4:5 as the recommended ratio and recommends 15 to 30 seconds. No 8frame video model makes 4:5, so generate 9:16 and crop it. Autoplay can be silent, so on-screen captions carry the message.
Can Veo 3.1 make square or 4:5 video for LinkedIn?
No. On 8frame Veo 3.1 makes 16:9 and 9:16 only. Crop a 4:5 or square version from the 9:16 clip, or generate 1:1 from text on Kling 2.6 Pro or Wan 3.0.
Does LinkedIn penalize AI-generated video?
We could not find a LinkedIn help page that says how AI-generated video is ranked, so we won't claim either way. The risk you control is social: obvious AI filler can get named in comments under your professional identity. Short, specific, well-captioned clips grounded in your real business are the safer bet.
