LinkedIn Video Marketing Guide: Best Practices, Length & Format for B2B

What You’ll Find in This Guide:

‍

In recent years, video has emerged as a highly relevant lever for LinkedIn content strategies. Several factors explain this trend. More and more users consume video content directly in their news feed or from their mobile devices. Publishing native video on LinkedIn increases your chances of being seen and engaging your community.

Video is also an effective way to capture attention. It combines image and sound while catching the eye. It's an efficient format for conveying complex messages (testimonials, product demos, case studies, company storytelling, etc.).

While video consumption has exploded in recent years—particularly with the arrival of TikTok and short-form content—LinkedIn has also unveiled this functionality for B2B. This content option allows B2B communicators and marketers to test a new format on the platform. It's a way to engage communities differently and speak directly to decision-makers and professionals. According to a study by Metricool, video content on LinkedIn increased by 53% in 2025.

Not sure what the best practices are for launching video communication on LinkedIn? Let us explain everything in this comprehensive guide.

Essential Technical Requirements for Your LinkedIn Videos

Before diving into creation, it's essential to master the technical constraints. At Les Années Folles, we've conducted numerous influencer campaigns with video content. At the end of 2025, for example, we produced a unique concept on LinkedIn for our client Cegid.

Based on our experience, here are some technical tips we're sharing:

Recommended format: MP4
Resolution & aspect ratio: Full HD 1080x1920 for standard videos. Your video should be edited in vertical format to facilitate viewing on mobile
Maximum file size: up to 5 GB, which leaves comfortable margin for long or high-quality videos
Recommended frame rate: 30 frames per second
Many users browse LinkedIn without sound (at the office, on public transport, in open-plan offices…). It's therefore strongly recommended to add subtitles to ensure comprehension
Plan for visuals and text that are sufficiently readable for mobile viewing, often in portrait mode or in a restricted feed

Understanding what types of content B2B influencers post on LinkedIn can help you determine when video is the most appropriate format for your message and audience.

What Is the Ideal Length for LinkedIn Videos Based on Your Objectives?

Choosing the right duration is crucial. Too long, and you risk losing attention; too short, and your message may lack depth. The ideal length depends on your objective.

Short Videos: Up to 2 Minutes

This is the format to prioritize for short content that can be viewed quickly. However, the shorter the video needs to be, the more upfront work is required to synthesize the messages you want to share. You also need dynamic editing to engage the user.

Here's a summary of what you need to know:

LinkedIn and many marketing agencies consider that videos between 30 seconds and 2 minutes offer a good compromise between impact and attention
For awareness objectives, quick storytelling, announcements, tips, or teasing content, this is the ideal format
According to an internal LinkedIn study: for advertising videos (ads), those under 30 seconds show completion rates up to +200%

The very short format should therefore be prioritized to quickly capture attention in a saturated feed, to deliver a simple, clear, useful message—a tip, an insight, guidance—or to maximize the chances that the video will be watched to the end.

Long Videos: Up to 10 Minutes

The long format allows users to share primarily tutorials or reactions to current events. It also enables thinking about real concepts. In 2025, we worked alongside HubSpot on creating a web series broadcast on LinkedIn. You can see the full scope of our project in our client case studies.

With this experience, here's what we can tell you about the long format:

LinkedIn allows publishing longer videos (up to 10 minutes) for company and personal pages
This type of video is relevant for content requiring more time: case studies, product demos, webinars, interviews, tutorials, in-depth storytelling, customer testimonials, etc.
This format can also be used for web series. You can therefore consider repurposing the produced content elsewhere
Even if the completion rate may be lower, this format allows you to demonstrate expertise, generate authority, and convince a professional audience ready to invest more time for high-value content

This format should be prioritized for complex topics requiring detail (technical demonstrations, analyses, deep-dive content), for B2B or professional audiences ready to invest time because they're seeking expertise, or to build legitimacy, thought leadership, trust, and encourage engagement (comments, shares, leads).

For an effective strategy, mixing short and long formats is often the best approach. Use short formats to tease, attract attention, generate volume, and long formats to go deeper, engage, and convince. Test, because there's no universal rule, only trends. Depending on your audience, your industry, and your content, results may vary.

When developing a comprehensive LinkedIn content strategy that includes video, consider how it fits within your broader approach. Learn more in our guide on launching a successful B2B influencer marketing campaign on LinkedIn.

Our Tips for an Effective LinkedIn Video

Producing an effective video on LinkedIn isn't limited to following the technical advice we listed previously. You also need to think about content, rhythm, and structure.

Here are some tips for planning your LinkedIn video content:

Hook Your Audience Immediately

The first 3 to 10 seconds are crucial. You need to capture attention immediately with a punchy hook, a surprising statistic, a question, or a strong visual.

Present Value Upfront

Quickly present the benefit, value, or problem the content will solve so the viewer knows immediately why they should watch.

Think "Value Before Sales"

On LinkedIn, high-performing videos are often those that provide an insight, advice, a vision, or testimony—not simply promotion.

Focus on Educational/Informative Formats

Think tutorials, best practices, experience feedback, analyses, and industry best practices. These formats work very well in B2B for building expertise and trust.

Structure Long Videos into "Chapters" or "Blocks"

Facilitate understanding, segment content, and allow the viewer to navigate easily.

Use Subtitles

Subtitles are essential on LinkedIn because many users watch without sound.

Perfect Your Visuals and Editing

A dynamic rhythm, clear visuals, and consistent design (colors, branding) strengthen impact and credibility.

End with a Clear Call-to-Action (CTA)

Often, video on LinkedIn aims for a specific objective: engagement, interaction, leads, website visits, downloads… Finish with a clear call-to-action to guide your audience. But be careful—the CTA must remain subtle, natural, and consistent with the topic you're addressing.
