 ## Features
 
- - exports list of scenes to .CSV file and terminal (both timecodes and frame numbers) with `list-scenes` command
  - exports timecodes in standard format (HH:MM:SS.nnn), comma-separated for easy copy-and-paste into external tools and analysis with spreadsheet software
  - statistics/analysis mode to export frame-by-frame video metrics via the `-s [FILE]`/`--stats [FILE]` argument (e.g. `--stats metrics.csv`)
  - output-suppression (quiet) mode for better automation with external scripts/programs (`-q`/`--quiet`)
  - save an image of the first and last frame of each detected scene via the `save-images` command
  - split the input video automatically if `ffmpeg` or `mkvmerge` is available via the `split-video` command
