SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Publishing content to social platforms fails or underperforms when exports use wrong dimensions, aspect ratios, codecs, or file sizes. This Skill provides verified technical specifications for Instagram, TikTok, YouTube Shorts, Facebook, and LinkedIn so you can validate media before publishing. ## Core Features & Use Cases - Platform Specification Tables: Dimensions, aspect ratios, duration limits, file size caps, and codec requirements for feed posts, Reels, Stories, Shorts, and LinkedIn carousels. - Export Checklist: A pre-publish checklist covering resolution, aspect ratio, file size, codec (H.264), frame rate, audio (AAC), and subtitles. - Safe Zone Guidance: UI-safe margins for Stories formats so text and key visuals are not covered by platform overlays. - Use Case: Before delivering a client video for Instagram Reels and TikTok, check this Skill to confirm 1080x1920 resolution, 9:16 ratio, H.264 codec, and file size under TikTok's 287.6MB limit. ## Quick Start Check the export specs for my video before I publish it to Instagram Reels and TikTok.

FAQPage Schema
What video dimensions should I use for Instagram Reels and TikTok?▼

Both Instagram Reels and TikTok use 1080x1920 pixels with a 9:16 aspect ratio. Reels run up to 3 minutes with H.264 at 30fps, while TikTok supports 15 seconds to 10 minutes with H.264 or H.265 and a 287.6MB file size limit.

How do I export video for YouTube Shorts?▼

Export YouTube Shorts at 1080x1920 with a 9:16 aspect ratio and a maximum duration of 3 minutes. Use H.264 codec at 30-60fps with AAC audio at 128kbps or higher.

What is the safe zone for Instagram Stories?▼

Instagram Stories use 1080x1920 (9:16) with a safe zone of 250 pixels at the top and bottom. Keep text and key visuals outside these areas because the platform UI overlays them.

LinkedIn carousels are PDF documents with up to 300 slides. Each slide should be 1080x1080 or 1080x1350 pixels for optimal display in the feed.
