Run the frame.sh script with the video path and an output file, optionally passing --time for a timestamp or --index for a frame number. It invokes ffmpeg with the appropriate seek or select filter and writes a single image.
Pass the --time argument in HH:MM:SS format, for example --time 00:00:10. The script uses ffmpeg's -ss seek option before decoding, which quickly jumps to that position and saves one frame.
Yes, the ffmpeg binary must be available on the system since the script calls it directly. The Skill metadata provides a Homebrew install option for ffmpeg on macOS.
Use JPG for quick sharing and smaller file sizes, and PNG when you need crisp detail such as UI screenshots. The output format is determined by the file extension you pass to --out.
Index-based extraction uses ffmpeg's select filter, which decodes frames sequentially until it reaches the target frame number. Timestamp extraction seeks directly to the position, which is typically much faster.
