LinkedIn Video Format Guide 2026: Specs, Settings, and Conversion

LinkedIn Video in 2026

LinkedIn has quietly become one of the most valuable platforms for video content — and also one of the most frustrating to upload to if you don't know the format requirements. Unlike Instagram or TikTok, where over-compressed uploads at least upload without errors, LinkedIn will outright reject files that don't meet its technical specs or silently degrade quality in ways that make professional content look amateurish.

The good news: LinkedIn's format requirements are well-defined and consistent. Once you know the specs, you can configure your export settings once and never worry about rejected uploads or blurry video again.

This guide covers native LinkedIn video (personal posts and company pages), LinkedIn video ads, and Live Video — with exact specs, recommended settings, and a conversion workflow for any source footage.

Native Video Specs (Feed Posts)

LinkedIn's native video format requirements are less strict than its ad specifications, but there are hard limits you need to stay within:

For company pages and LinkedIn Pages, the specs are identical to personal native video. LinkedIn does not distinguish between the two in terms of format requirements.

LinkedIn Video Ad Specs

LinkedIn video ads have much stricter requirements than native video. If you're running sponsored campaigns, get these right before creating ad sets — a rejected creative delays campaigns and wastes budget:

The 200 MB file size limit for ads is the single most common cause of rejected LinkedIn video creatives. A 30-second 1080p H.264 clip can easily exceed 200 MB if exported at high bitrate from Premiere or Final Cut. You need to compress it down before uploading.

The Best Aspect Ratios for LinkedIn

LinkedIn supports multiple aspect ratios, but not all perform equally:

4:5 (1080×1350) — Best for mobile engagement. This vertical-ish portrait format takes up the most screen real estate in the LinkedIn mobile feed. If your analytics show a high mobile audience, 4:5 is the strongest choice for organic reach.

1:1 (1080×1080) — Safe universal choice. Square video performs well on both desktop and mobile. It's less dominant than 4:5 on mobile but doesn't get letterboxed on desktop like 9:16 does.

16:9 (1920×1080) — Best for desktop viewers. Traditional widescreen works well for webinar clips, presentations, and demo videos where the landscape frame is intentional. Less effective in the mobile feed.

9:16 (1080×1920) — Vertical ads only. LinkedIn added vertical format support for ads, but native 9:16 posts get cropped in the feed. Use this exclusively for paid campaigns.

Converting Video to LinkedIn's Format

If your source footage is in MOV, MKV, AVI, or any format other than H.264 MP4, you need to transcode before uploading. Use the video converter for a quick web-based conversion, or use FFmpeg for command-line control:

# Convert MOV to LinkedIn-optimized MP4 (16:9, 1080p, 30fps)
ffmpeg -i input.mov \
  -c:v libx264 \
  -preset slow \
  -crf 22 \
  -vf "scale=1920:1080,fps=30" \
  -c:a aac \
  -b:a 192k \
  -movflags +faststart \
  output-linkedin.mp4

# Convert to 4:5 (1080x1350) for mobile feed
ffmpeg -i input.mp4 \
  -c:v libx264 \
  -preset slow \
  -crf 22 \
  -vf "scale=1080:1350:force_original_aspect_ratio=decrease,pad=1080:1350:(ow-iw)/2:(oh-ih)/2,setsar=1,fps=30" \
  -c:a aac \
  -b:a 192k \
  -movflags +faststart \
  output-linkedin-45.mp4

# Compress for LinkedIn ads (keep under 200MB)
ffmpeg -i input.mp4 \
  -c:v libx264 \
  -preset medium \
  -b:v 3M \
  -maxrate 4M \
  -bufsize 8M \
  -vf "scale=1280:720,fps=30" \
  -c:a aac \
  -b:a 128k \
  -movflags +faststart \
  output-linkedin-ad.mp4

The -movflags +faststart flag moves the MP4 header to the front of the file, which allows LinkedIn to start processing the video immediately on upload rather than waiting for the complete file transfer.

Trimming and Editing Before Upload

LinkedIn doesn't have a built-in trimmer for native video uploads. If you need to cut your video before uploading, use the video trimmer to cut the clip to your desired length. For repurposing long-form content (webinars, interviews, conference talks) into shorter LinkedIn clips, trimming the best 30–60 seconds is often more effective than uploading the full recording.

If you're extracting a clip from a longer recording:

# Extract 45 seconds starting at 2:30
ffmpeg -i full-webinar.mp4 \
  -ss 00:02:30 \
  -t 00:00:45 \
  -c:v libx264 -crf 22 -c:a aac -b:a 192k \
  -movflags +faststart \
  clip-linkedin.mp4

Adding Captions for Silent Viewing

85% of LinkedIn video is watched without sound — either because viewers are at work, in public, or have auto-play muted. Captions aren't optional for professional content; they're essential.

LinkedIn accepts SRT (SubRip Subtitle) files uploaded alongside your video. Create a basic SRT file manually or use an AI transcription service to generate one automatically.

SRT format looks like this:

1
00:00:00,000 --> 00:00:03,500
Welcome to our quarterly product update.

2
00:00:03,500 --> 00:00:07,200
This quarter we shipped three major features.

3
00:00:07,200 --> 00:00:12,000
Let me walk you through each one.

Upload the SRT file in the "Add captions" step during the LinkedIn post creation flow. LinkedIn displays captions automatically for silent viewers.

Compressing Oversize Videos

If your video exceeds the 200 MB limit for ads (or you just want faster uploads), the video compressor can reduce file size while maintaining acceptable quality. For ads specifically, targeting 720p at 3–4 Mbps bitrate usually produces a well-balanced file under 200 MB for clips under 60 seconds.

The quality reduction at 720p vs 1080p is barely noticeable in the LinkedIn feed — especially on mobile. Don't over-optimize for resolution when file size is the priority for ads.

LinkedIn Live Video Requirements

LinkedIn Live has separate requirements from uploaded video:

• Protocol: RTMP
• Recommended bitrate: 3,500–5,500 kbps (video) + 128–192 kbps (audio)
• Resolution: 720p (1280×720) minimum, 1080p (1920×1080) recommended
• Keyframe interval: 2 seconds
• Codec: H.264 (video), AAC (audio)
• Frame rate: 30 fps

LinkedIn Live requires applying for access through LinkedIn's Live Broadcasting program. Once approved, you stream via OBS, Streamlabs, or any RTMP-compatible broadcast tool using the stream key LinkedIn provides.

Automating LinkedIn Video Creation

If you're producing LinkedIn video at scale — for example, turning weekly blog posts into short video clips — having a consistent export workflow matters. Many teams use batch processing pipelines that automatically trim, compress, and caption video content.

A basic automation pipeline might look like:

1. Record or export source footage (MOV/AVI from camera or screen recorder)
2. Trim to 30–60 seconds with FFmpeg or the video trimmer
3. Transcode to H.264 MP4 at 1080p or 1350p (4:5)
4. Generate SRT captions with Whisper or a transcription API
5. Verify file size (fail if >5GB native or >200MB ad)
6. Upload via LinkedIn API or manually

Frequently Asked Questions

Why does LinkedIn compress my video so much?

LinkedIn re-encodes all uploaded videos for its own streaming infrastructure. Videos uploaded in non-optimal formats (MKV, AVI, MOV with ProRes) or at excessive bitrates trigger more aggressive re-encoding. Uploading a clean H.264 MP4 at 8–12 Mbps gives LinkedIn's encoder the best source to work with, resulting in better quality after their processing.

Can I upload 4K video to LinkedIn?

Yes — LinkedIn accepts up to 4096×2304. However, 4K video provides no advantage on LinkedIn since the platform's player caps streaming quality well below 4K for most connections. Upload 1080p for the best balance of quality and upload speed.

Why was my LinkedIn video ad rejected?

The most common reasons: file size over 200 MB, unsupported audio codec (use AAC), missing audio track (LinkedIn requires audio), or an unsupported aspect ratio. Check the LinkedIn Campaign Manager rejection message — it usually specifies which requirement failed.

Do I need captions for every video?

Captions aren't technically required for native posts, but they're essential for engagement. Aim for 100% caption coverage on your LinkedIn video posts. For ads, captions are required by LinkedIn's advertising policies for accessibility compliance.

What happens if I upload a vertical 9:16 video as a native post?

LinkedIn will display it with black bars (letterboxing) in the desktop feed, making it look unprofessional. Native posts look best in 4:5, 1:1, or 16:9. Use 9:16 only for LinkedIn video ads, not organic posts.

Conclusion

LinkedIn video rewards creators who take format seriously. Get the specs right — H.264 MP4, 8–12 Mbps, 1080p, 30 fps for native posts; under 200 MB for ads — and your video will look exactly as intended in every feed and on every device.

For source footage in the wrong format, the video converter handles transcoding to LinkedIn-ready MP4 in seconds. For oversized ad creatives, the video compressor brings files under 200 MB without visible quality loss.

The investment in format optimization pays off every time you publish — professional-looking video builds credibility in a way that blurry, artifact-ridden uploads never will.
