cutter

Cutter is a command-line tool that allows you to cut a video file or a folder containing multiple video files based on silence and noise level. It is based on Remsi, a library for audio and video processing. The tool is implemented in Python and can be used on Windows, Linux, and Mac OS.

Cutter can be used to speed up videos in a folder like school lessons, lectures, etc removing the silence parts or changing speed time.

Installation

Pre builds are available in the releases.

Before installing cutter (if you don't use the pre build version), you must have installed ffmpeg and python. Clone the repository from GitHub and install the required dependencies using pip:

git clone https://github.com/guray00/cutter.git
cd cutter
pip install -r requirements.txt

Usage

Cutter is a command-line tool, therefore you must use it from the terminal (on windows you can open a terminal in the same folder thanks to open_cmd_here.cmd). The usage is the following:

usage: cutter.exe [-h] [-d D] [-n N] [-fr FR] [-x X] [-vfr] [--keep-cfr] [--preview] path

positional arguments:
  path        the path of the video or the folder (for many videos) to cut

options:
  -h, --help    show this help message and exit
  -d D          duration of silence in seconds
  -n [-80,-20]  noise level in dB (from -80 to -20)
  -fr FR        output video frame rate
  -x X          Speed of the video
  -vfr          variable frame rate on output (if -fr is given, it indicates the max number of duplicates frames per
                second)
  --keep-cfr    keeps Constant Frame Rate version of the file for future editing.
  --preview     makes a preview of 180 seconds

Examples

To cut a single video file with a silence duration of 1 second and a noise level of -30 dB:

.\cutter.exe -d 1 -n -30 path/to/video.mp4

To cut all the video files in a folder with a silence duration of 0.5 seconds and a noise level of -45 dB, and create a preview of each file:

.\cutter.exe --preview -d 0.5 -n -45 path/to/folder

To cut a single video file with a silence duration of 1 second and a noise level of -30 dB, and keep the Constant Frame Rate version of the file:

.\cutter.exe -d 1 -n -30 --keep-cfr path/to/video.mp4

Compile

Windows

Create a folder bin and copy ffmpeg.exe and ffprobe.exe files, after:

pyinstaller -F --add-data ".\bin;." --runtime-hook ".\.exports\win_export.py" .\cutter.py

The compiled version will be in the dist folder.

Linux

Create a folder bin and copy ffmpeg and ffprobe files, after:

python3 -m PyInstaller -F --add-data "./bin:." --runtime-hook "./.exports/linux_export.py" ./cutter.py

The compiled version will be in the dist folder.
