The skill accepts flexible timestamp formats:
- MM:SS:
01:30(1 minute 30 seconds) - HH:MM:SS:
01:15:30(1 hour 15 minutes 30 seconds) - M:SS:
1:30(same as 01:30) - SS:
90(converted to 01:30)
How Clipping Works
- You provide a YouTube URL and time range
- Claude parses your timestamps
- The skill extracts just that section using optimized methods:
- Method 1: yt-dlp's native clipping (fastest)
- Method 2: ffmpeg precise cutting (fallback)
- Your clip is saved to the current directory
