Video Edit
Edit videos locally with ffmpeg commands—trim, concat, resize, compress, and convert
What You Can Do
You can perform professional-grade video editing operations entirely on your machine using ffmpeg. Cut segments from videos, join multiple clips together, resize for social platforms (TikTok, Instagram, YouTube), adjust playback speed, extract or replace audio tracks, compress files for storage, and convert between formats—all with copy-paste ffmpeg commands that Claude generates based on your specific requirements.
Features
Example Output
Example 1: Trim a video
ffmpeg -y -ss 00:00:30 -to 00:01:45 -i video.mp4 -c copy trimmed.mp4
Creates a 1-minute 15-second clip starting at 30 seconds into the original video.
Example 2: Resize for TikTok
ffmpeg -y -i video.mp4 -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:black" tiktok.mp4
Resizes to 1080×1920 with black letterboxing to maintain aspect ratio.
Example 3: Concatenate clips
printf "file '%s'\n" clip1.mp4 clip2.mp4 clip3.mp4 > list.txt
ffmpeg -y -f concat -safe 0 -i list.txt -c copy joined.mp4
Joins three video files seamlessly into a single output.

You can transform raw video footage into structured, professional content by leveraging AI to identify key moments, organize clips, transcribe audio, and augment with voiceovers, overlays, and subtitles. This skill guides you through a proven pipeline that emphasizes compression and smart structuring rather than AI generation—turning hours of footage into minutes of compelling content optimized for any platform.

You can break down video content into individual frames and aligned audio segments at any interval you specify. This skill generates PNG images for visual analysis, extracts corresponding audio clips in AAC format, and creates a JSON manifest that maps every frame to its timestamp and audio file—perfect for preparing video content for detailed review, transcription workflows, or handing off to other agents for automated processing.
