Social media video spec requirements are the platform-enforced technical standards that determine whether your video displays at full quality, gets cropped, or gets rejected entirely. Platform specs cover resolution, aspect ratio, file size, file format, video length, frame rate, and bitrate. These are not suggestions. Every major platform from Facebook and Instagram to TikTok, YouTube, LinkedIn, and Snapchat enforces them automatically. Upload a video that mismatches even one parameter and you risk silent penalties: lower reach, automatic cropping, or compression artifacts that make your work look amateurish. Tools like Sprout Social and Vizup have documented exactly how these rules play out in practice, and what we cover here draws directly from that research.
1. Social media video spec requirements: the universal baseline
Before you open a platform-specific spec sheet, you need a solid technical foundation that applies almost everywhere. Getting these fundamentals right prevents the most common and damaging mistakes.
Container formats and codecs
Most platforms accept MP4 or MOV container formats. H.264 is the standard video codec across Facebook, Instagram, TikTok, YouTube, LinkedIn, and Snapchat. AAC is the standard audio codec. If you export anything outside these defaults, you are gambling on whether the platform’s transcoder handles it gracefully. Spoiler: it usually does not.
Frame rates and resolution
Frame rates generally fall between 23 and 60 fps, with 30 fps being the most universally safe choice. Resolution targets vary by placement, but 1080p is the practical floor for any content you want to look sharp after platform re-encoding. Going below 1080p at upload means the platform has nothing to work with when it compresses your file.
File size and bitrate
Here is where most producers make a costly mistake. Max file size limits are not quality targets. Uploading a 3.8 GB file to a platform that allows 4 GB does not mean you get better quality. The platform re-encodes everything, and a bloated file often produces worse results than a clean, well-encoded 300 MB file. Target exports under 500 MB for most social placements, with bitrates in the 15 to 30 Mbps range for the best delivered appearance.
Container: MP4 or MOV
Video codec: H.264
Audio codec: AAC
Frame rate: 23 to 60 fps (30 fps recommended)
Resolution floor: 1080p
Target file size: Under 500 MB for most placements
Bitrate target: 15 to 30 Mbps
Pro Tip: Build a master export preset library organized by platform and placement before your next project kicks off. Spending 30 minutes setting up presets in Adobe Premiere Pro or DaVinci Resolve saves hours of last-minute re-exports and eliminates spec errors at delivery.
2. Facebook and Instagram video specs for feeds, stories, and reels
Facebook and Instagram share Meta’s infrastructure, but their video specs differ meaningfully by placement. Treating them as identical is one of the most common and expensive mistakes in a social media video ad specs workflow.
Facebook feed and Instagram feed
Facebook Feed supports videos up to 241 minutes long, but optimal engagement duration is 15 to 30 seconds. The technical limit is not a creative license. For feed placements, 1080x1350 pixels at a 4:5 aspect ratio performs best because it occupies more vertical screen real estate than a standard 16:9 frame. Use MP4 or MOV, H.264, AAC audio, and keep your file under 4 GB, though under 500 MB is the practical target.
Stories
Stories on both platforms use a 9:16 vertical format at 1080x1920 resolution. Duration caps at 15 seconds per card for organic Stories, though paid placements can run up to 120 seconds. The critical detail here is the safe zone structure: the top 14% and bottom 20% of the frame are reserved for UI overlays including the profile handle, call-to-action buttons, and navigation elements. Any text, logo, or key visual placed in those zones will be obscured.
Reels
Instagram Reels require 9:16 at 1080x1920, MP4 or MOV, with video length up to 90 seconds. For Reels tab eligibility specifically, the API publishing rules are stricter: the video must be exactly 9:16 and between 5 and 90 seconds. A video that falls outside those parameters may upload successfully as a regular post but will never surface in the Reels tab. That distinction matters enormously for organic reach. The Reels safe zone is even more aggressive than Stories, with the bottom 35% reserved for UI elements.
Placement | Resolution | Aspect Ratio | Max Duration | Safe Zone Risk |
Facebook Feed | 1080x1350 | 4:5 | 241 min (30 sec optimal) | Low |
Instagram Feed | 1080x1080 or 1080x1350 | 1:1 or 4:5 | 60 min | Low |
Stories | 1080x1920 | 9:16 | 15 sec (120 sec paid) | High (top 14%, bottom 20%) |
Reels | 1080x1920 | 9:16 | 90 sec | High (bottom 35%) |
Pro Tip: Export separate versions of every vertical video for Stories and Reels. The safe zone boundaries are different enough that a single export will compromise one placement or the other. Two exports take 10 minutes. Fixing a cropped logo after a campaign launches takes much longer.
3. TikTok, YouTube, LinkedIn, and Snapchat video specs
Each of these platforms has a distinct native format, and assuming cross-platform compatibility without adjusting specs is a reliable way to underperform on all of them.
TikTok
TikTok is a vertical-first platform. The 9:16 format dominates TikTok, Instagram Reels, and Snapchat, making it the most important aspect ratio for short-form content in 2026. TikTok’s ideal video duration for organic content sits between 5 and 60 seconds for maximum completion rates, though the platform supports longer uploads. Maximum file size is 287.6 MB for iOS and 72 MB for Android when uploading natively, which makes file size management more critical here than on Meta platforms. Export at 1080x1920, H.264, AAC, and keep your file lean.
YouTube
YouTube is a different animal entirely. Landscape 16:9 is the standard for uploaded videos, with resolutions ranging from 240p up to 8K. For most marketing and production work, 1080p at 16:9 is the baseline, with 4K becoming increasingly expected for brand content. YouTube supports very long durations and large file sizes, making it the most forgiving platform technically. That said, YouTube Shorts follows the same 9:16 vertical spec as TikTok and Reels, so you still need separate exports if you are distributing across both formats.
LinkedIn video supports aspect ratios of 1:1, 16:9, and 9:16, with a maximum file size of 500 MB. Recommended duration for LinkedIn video ads is 15 seconds to 30 minutes, though organic posts perform best under 3 minutes. LinkedIn’s audience skews professional, so the platform rewards clear, information-dense content over high-energy short-form. Use MP4, H.264, and AAC as your baseline.
Snapchat
Aspect ratio: 9:16 vertical
Resolution: 1080x1920
Max file size: 1 GB
Duration: 3 to 180 seconds for Snap Ads
Format: MP4 or MOV, H.264, AAC
Safe zones: Similar to Stories; keep critical elements in the center third of the frame
4. Export presets, safe zones, and a production QA workflow
Knowing the specs is half the job. Building a workflow that applies them consistently on every project is what separates professional production teams from those who are always scrambling at delivery.
Building export presets
Create named export presets in Adobe Premiere Pro or DaVinci Resolve for every platform and placement combination you deliver regularly. A preset named “Meta Reels 9x16 H264 AAC” removes all guesswork at export time. Each preset should lock in the resolution, codec, bitrate, frame rate, and target file size. This is not overhead. It is quality control built into your tools.
Designing for safe zones
For vertical formats, build a safe zone guide layer directly into your editing timeline. Keep all text, logos, calls to action, and critical product visuals within the center 60% of the frame vertically. Cross-posting without adjusting safe zones risks obscuring key elements under UI overlays, which undermines the entire communication goal of the video. A safe zone template takes 15 minutes to build and protects every project that follows.
Pre-upload QA checklist
Before any video goes live, run through this checklist:
Confirm codec is H.264 video and AAC audio using a tool like MediaInfo or VLC
Verify resolution matches the target placement exactly
Check frame rate against platform requirements
Confirm file size is under the practical target (not just the maximum)
Preview the video in a simulated safe zone overlay to catch any cropped elements
Verify duration falls within the placement’s eligibility window, especially for Reels API publishing
Pro Tip: Use Meta’s Advantage+ asset customization feature when running ads across multiple placements. It lets you assign specific video versions to specific placements within a single campaign, so your 4:5 feed video and your 9:16 Reels video each go exactly where they belong without manual trafficking errors.
Treating spec compliance as a QA gate rather than an afterthought is the single biggest workflow upgrade most production teams can make. Build it into your delivery checklist the same way you would a color grade review or an audio mix check.
Key takeaways
Meeting social media video spec requirements demands platform-specific exports, safe zone discipline, and a pre-upload QA process built into every production workflow.
Point | Details |
Universal codec baseline | Use H.264 video and AAC audio for every platform to avoid transcoding failures. |
File size is not quality | Export under 500 MB with 15 to 30 Mbps bitrate for best post-encoding quality on Meta. |
Safe zones are non-negotiable | Keep critical visuals out of the top 14% and bottom 20 to 35% on vertical formats. |
Reels API eligibility | Videos must be exactly 9:16 and 5 to 90 seconds to appear in the Instagram Reels tab. |
Separate exports per placement | Cross-posting a single file across platforms without adjusting specs degrades quality and reach. |
Why specs compliance is the unglamorous work that wins campaigns
I have been in production long enough to watch genuinely great creative work underperform because someone uploaded the wrong file. A beautifully shot brand video, color graded to perfection, delivered at the wrong aspect ratio for a Stories placement. The logo sat under the profile handle. The call to action was buried beneath the swipe-up prompt. The client saw the numbers and blamed the concept.
The truth is that platform specs are enforced rules, not guidelines, and the penalties for ignoring them are often invisible. You do not always get an error message. Sometimes you just get lower reach and worse performance, and you never connect it to the file you uploaded.
What I have learned over two decades of production is that the teams who consistently outperform on social media are not always the most creative. They are the most disciplined about the technical side. They build spec-compliant workflows before the first frame is shot, not after the edit is locked. They treat a pre-upload QA checklist the same way a surgeon treats a pre-op checklist. It is not optional.
The creative vision and the technical compliance are not in conflict. You can make something beautiful and make it work correctly on every platform. The producers who understand both are the ones clients call back.

FAQ
What video format works across all social platforms?
MP4 with H.264 video codec and AAC audio is the most universally accepted format across Facebook, Instagram, TikTok, YouTube, LinkedIn, and Snapchat. It delivers reliable compatibility and clean transcoding results on every major platform.
Why does my video look blurry after uploading?
Platform re-encoding degrades quality when your source file is too large or poorly encoded. Export at 15 to 30 Mbps with a file size under 500 MB to give the platform’s encoder the cleanest possible input and the best delivered output.
What aspect ratio should I use for social media videos?
The right aspect ratio depends on the placement. Use 9:16 for TikTok, Instagram Reels, Stories, and Snapchat. Use 16:9 for YouTube. Use 4:5 or 1:1 for Facebook and Instagram feed placements to maximize screen real estate.
What are safe zones in social media video?
Safe zones are the areas of the frame where UI elements like profile handles, captions, and buttons appear. On Instagram Stories, the top 14% and bottom 20% are reserved. On Reels, the bottom 35% is at risk. Keep all critical visuals centered to avoid being obscured.
Does Instagram Reels have stricter specs than regular posts?
Yes. For Reels tab eligibility through the API, videos must be exactly 9:16 aspect ratio and between 5 and 90 seconds. Videos outside those parameters may upload but will not surface in the Reels tab, significantly limiting organic reach.
