What problem does it solve? Adapting one finished video for LINE, YouTube, Shorts, Instagram, Reels, Facebook, and TikTok requires juggling different aspect ratios, durations, codecs, and caption safe areas, and mistakes lead to cropped content or rejected uploads. ## Core Features & Use Cases - Export Matrix Planning: Builds a per-platform matrix covering aspect ratio, frame size, crop strategy, caption position, duration, bitrate, filename, and thumbnail. - Intentional Reframing: Crops, tracks subjects, or adds designed padding so important content is never lost when changing orientation. - Compression & QA: Uses CRF-based H.264/AAC MP4 encoding with yuv420p, verifies outputs with ffprobe, and checks captions, logos, and safe areas. - Use Case: You have an approved 16:9 master video and need a 9:16 LINE version with readable captions, a Shorts version, and a square Facebook post, each with explicit filenames like topic-line-1080x1920.mp4. ## Quick Start Use video-social to export my approved master video into LINE, Shorts, and Instagram Reels versions with correct sizes, captions, and filenames.
