What problem does it solve? Editing videos for social platforms usually requires heavy GUI software or memorizing complex ffmpeg flags. This Skill provides ready-to-run ffmpeg and ffprobe commands for the most common video editing operations, so you can trim, resize, compress, and convert videos directly from the command line. ## Core Features & Use Cases - Trim and Concatenate: Cut segments with stream copy for speed, or join multiple clips using the concat demuxer. - Platform Resizing: Built-in scale-and-pad presets for TikTok (1080x1920), YouTube (1920x1080), Instagram (1080x1350), and square formats. - Audio Operations: Extract audio to MP3/WAV/AAC, replace audio tracks, or mix original audio with new music. - Compression and Conversion: CRF-based compression, target file size calculation, and high-quality two-pass GIF conversion. - Use Case: You recorded a horizontal product demo and need a vertical TikTok version with a logo watermark. Use the resize preset with the pad filter, then apply the overlay command to place your logo in the corner. ## Quick Start Ask the AI to trim the first 30 seconds of demo.mp4 and resize it to 1080x1920 for TikTok using this video editing skill.
