Short video production is the art and science of creating engaging 15-60 second vertical videos optimized specifically for Xiaohongshu's mobile-first, algorithm-driven platform. This skill encompasses the complete workflow from concept through filming, editing, and optimization—combining compelling storytelling, visual appeal, rapid pacing, and concise delivery to capture viewer attention within milliseconds and retain it through completion. The core principle: on mobile platforms with endless c

FFmpeg automation for cutting, trimming, concatenating, and exporting videos with audio mixing and platform optimization. \n \n Supports cutting, trimming, concatenation, transitions, effects, and color grading through FFmpeg CLI automation \n Handles audio mixing, normalization, and synchronization; subtitle burning and soft-subtitle handling \n Provides platform-specific export presets for YouTube, Instagram, Twitter, TikTok, and web delivery with bitrate and resolution optimization \n Batch p

Apply Disney's 12 animation principles to After Effects, Premiere Pro, and video motion design.

This skill provides guidance for video processing tasks involving frame-level analysis, event detection, and motion tracking using computer vision libraries like OpenCV. It emphasizes verification-first approaches and guards against common pitfalls in video analysis workflows.

Use this skill to build from live Remotion Bits examples first, then fall back to primitives only when the examples are not enough.
