LinkedIn Video Ad Specifications for Indian D2C Brands & E-commerce Sellers (2026)

• File sizes must range between 75 KB and 200 MB for standard in-feed ads, capping at 30 frames per second (fps).
• H.264 codec and AAC audio are strictly enforced; uploading ProRes or HEVC files will result in instant rejection [5].
• Vertical (9:16) videos require top and bottom UI safe zones to prevent profile icons and CTAs from blocking text.
• Sound-off viewing dominates; burned-in open captions or uploaded SRT files are mandatory for high view-through rates.
• Automated tools like Koro can instantly resize and format ad creatives to meet these strict specifications.

Navigating Campaign Manager can be tedious if your video files aren't pre-formatted correctly. LinkedIn strictly enforces its file size, frame rate, and codec limits before allowing you to hit publish. Here is the universal baseline for 2026.

• File Size: Minimum 75 KB, Maximum 200 MB (Some formats allow up to 500 MB, but 200 MB is the safest baseline) [1].
• File Format: MP4 only.
• Frame Rate: Maximum 30 fps (do not upload 60 fps gaming or high-motion footage without downsampling).
• Audio Codec: AAC or MPEG4.
• Video Codec: H.264.
• Duration: 3 seconds to 30 minutes (though 15-30 seconds is optimal for performance).

Keep this checklist handy when exporting from Premiere Pro, DaVinci Resolve, or CapCut. Failing to meet these baseline requirements will result in a red error banner during the upload process.

LinkedIn offers multiple placements, each with unique aspect ratio requirements. Understanding the difference between in-feed and CTV placements is critical for Indian D2C agencies running omnichannel campaigns.

Sponsored Content In-Feed Video Ads

In-feed video is the most common format. You can use three primary aspect ratios: Landscape (16:9), Square (1:1), and Vertical (4:5 or 9:16). Square videos (1080x1080) generally perform best across both mobile and desktop feeds. Vertical 9:16 videos (1080x1920) dominate mobile but may be cropped on desktop screens [3].

Thought Leader Video Ads

Promoting a founder's or executive's post requires the same specifications as standard in-feed videos. However, because these look like organic posts, authentic 1:1 or 4:5 aspect ratios shot on mobile phones tend to yield lower CPCs. Ensure the video is natively uploaded to the creator's profile first.

LinkedIn Connected TV (CTV) Video Ads

For B2B brands scaling into premium placements, LinkedIn CTV ads require high-definition landscape formats. These must be exactly 16:9 (1920x1080 or 3840x2160). The file size limit is often relaxed up to 500 MB, but the H.264 codec rule remains absolute.

One of the biggest mistakes performance marketers make is ignoring the mobile user interface (UI) overlays. When running 9:16 vertical video ads, LinkedIn places engagement buttons, ad copy, and profile icons directly over your video.

If you place crucial text, logos, or product demonstrations in these overlay zones, users won't see them. The bottom 20% of a vertical video is typically obscured by the headline, CTA button, and description. The top 10% is often covered by the profile name and the "Promoted" tag.

Always design your creatives with a "center-safe" mentality. Keep all burned-in captions, core product shots, and text hooks within the middle 70% of the screen. This ensures your message remains legible regardless of the device the prospect is using.

Exporting your video correctly from your non-linear editor (NLE) saves hours of troubleshooting. LinkedIn's infrastructure is notoriously strict regarding its 30 fps cap and H.264 codec requirement.

When exporting, set your target bitrate between 10 Mbps and 30 Mbps for 1080p footage. Going higher won't improve visual quality on the feed, as LinkedIn compresses the file aggressively, but it will unnecessarily bloat your file size closer to the 200 MB limit.

Ensure your audio is set to AAC at 192 kbps or 256 kbps. Finally, double-check that your frame rate is exactly 29.97 or 30 fps. Uploading a 60 fps file will immediately trigger an "Unsupported Video Format" error in Campaign Manager [4].

Over 70% of LinkedIn videos are watched on mobile devices with the sound muted. If your video ad relies entirely on a voiceover without text, your view-through rate (VTR) will plummet.

You have two options for captions. The first is uploading an SRT file alongside your video in Campaign Manager. This provides closed captions that users can toggle. However, SRT styling is basic and controlled by the platform.

The second, more effective option is burned-in open captions. These are permanently rendered onto the video file. Burned-in captions allow you to use brand colors, custom fonts, and dynamic animations to hold attention. For Indian D2C brands, dynamic burned-in captions dramatically increase hook retention rates.

While LinkedIn allows videos up to 30 minutes long, creative duration should strictly match your campaign objective. For brand awareness and top-of-funnel campaigns, keep videos under 15 seconds.

Short-form videos (under 15 seconds) loop automatically in the feed, which artificially boosts impression frequency and brand recall. If your goal is lead generation or complex product explanation, videos between 30 and 60 seconds perform best.

Always front-load your core value proposition within the first 3 seconds. The drop-off rate on LinkedIn is steep; if you don't hook the viewer immediately, the rest of your 60-second product demo will go unseen.

Even experienced media buyers run into Campaign Manager errors. The most common error is "File Size Exceeds Limit," which happens when marketers upload uncompressed 4K files.

If you see an "Invalid Aspect Ratio" error, your video likely falls outside the accepted standard dimensions (like a 3:4 video instead of 4:5). You must crop the video to exactly 1:1, 16:9, or 4:5 before re-uploading.

Another frequent issue is the "Audio Codec Not Supported" error. This occurs when exporting with uncompressed WAV or PCM audio. Always ensure your export preset explicitly selects AAC audio to bypass this rejection.

Manually resizing, captioning, and exporting videos for every platform is a massive bottleneck for lean marketing teams. Automating technical compliance ensures you launch campaigns faster without dashboard rejections.

For Indian D2C brands and agencies, using AI tools can eliminate this friction. For example, Koro allows you to generate UGC Videos or Edited UGC Videos that are already optimized for platform-specific aspect ratios. You don't have to worry about frame rates or codecs; the output is native and ready to upload.

While Koro focuses heavily on generating the actual creative (like AI actors in 10+ Indian languages), its ability to export compliant 1:1 or 9:16 ads means performance marketers spend less time in Premiere Pro and more time optimizing their bids and targeting. Plans start at ₹999/month, making it a scalable solution for high-volume ad testing.
