Validate hard limits for video uploads across platform formats and reduce failed publish attempts.
Enter your current video values and compare them against selected platform requirements.
Quickly confirm that your Reels, Shorts, or TikTok files meet platform requirements before uploading. Prevent upload failures and avoid quality loss from platform re-compression.
Standardize pre-publish video QA across multiple platforms to eliminate re-render cycles caused by spec mismatches. Turn validated parameters into reusable export templates for consistent production.
Verify target platform requirements before final export so you do not discover format issues after rendering is done. Save time by catching duration, resolution, or size problems early in the workflow.
Every major platform enforces specific hard limits on video duration, resolution, frame rate, and file size. Using a spec checker before publishing helps you catch issues early and avoid upload failures or forced quality compression by the platform.
A social media video spec checker is a validation tool that compares your video parameters against the hard limits enforced by each publishing platform. It covers formats like Instagram Reels, TikTok, YouTube Shorts, and long-form YouTube, checking duration, file size, resolution, frame rate, and bitrate. The tool reads video file metadata directly in your browser without uploading files to any server.
Platform requirements differ significantly: Instagram Reels allows a maximum of 90 seconds while YouTube long-form supports hours of content; TikTok defaults to 9:16 vertical while LinkedIn favors horizontal. Exceeding file size or format limits can trigger upload rejection or automatic quality compression, degrading your video's visual impact. Checking specs before export allows you to adjust settings without starting the render pipeline from scratch.
Select your target platform and post format, such as Instagram Reels, then upload a video file or enter parameters manually. The tool compares each dimension against platform rules and flags pass, warning, or fail status. Run all five checks together before exporting your final cut. For formats you publish regularly, save the passing parameter set as a team export template so future videos start from a validated baseline.
Maintain a parameter template for each platform and format you publish to regularly rather than checking from scratch each time. Avoid reusing the same export file across platforms since aspect ratio and duration tolerances differ. In team settings, a shared export template reduces person-to-person inconsistency and improves overall publish reliability.
