PySceneDetect is completely free software, and can be downloaded from the links below. See the license and copyright information page for details. If you have trouble running PySceneDetect, ensure that you have all the required dependencies listed in the Dependencies section below.

PySceneDetect requires at least Python 3.7 or higher.

Install via pip      

Including OpenCV (recommended):

pip install --upgrade scenedetect[opencv]

Including Headless OpenCV (servers):

pip install --upgrade scenedetect[opencv-headless]

PySceneDetect is available via pip as the scenedetect package.

Windows Build (64-bit Only)  

Latest Release: v0.6.4

  Release Date:  June 10, 2024

  Installer  (recommended)        Portable .zip        Getting Started

Post Installation

After installation, you can call PySceneDetect from any terminal/command prompt by typing scenedetect (try running scenedetect --help, or scenedetect version). If you encounter any runtime errors while running PySceneDetect, ensure that you have all the required dependencies listed in the System Requirements section above (you should be able to import numpy and import cv2). If you encounter any issues or want to make a feature request, feel free to report any bugs or share some feature requests/ideas on the issue tracker and help make PySceneDetect even better.


Python Packages

PySceneDetect requires Python 3 and the following packages:

  • OpenCV: pip install opencv-python
  • Numpy: pip install numpy
  • Click: pip install Click
  • tqdm: pip install tqdm
  • appdirs: pip install appdirs

Optional packages:

  • PyAV: pip install av

Video Splitting Tools

For video splitting support, you need to have one of the following tools available (included in Windows builds):

  • ffmpeg, required to split video files (split-video or split-video -c/--copy)
  • mkvmerge, part of mkvtoolnix, command-line tool, required to split video files in stream copy mode (split-video -c/--copy only)

The ffmpeg and/or mkvmerge command must be available system wide (e.g. in a directory in PATH, so it can be used from any terminal/console by typing the command), or alternatively, placed in the same directory where PySceneDetect is installed. On Windows this is usually C:\PythonXY\Scripts, where XY is your Python version. For more information, see the CLI documentation.

Building OpenCV from Source

If you have installed OpenCV using pip, you will need to uninstall it before installing a different version of OpenCV, or building and installing it from source.

You can click here for a quick guide (OpenCV + Numpy on Windows & Linux) on installing OpenCV/Numpy on Windows (using pre-built binaries) and Linux (compiling from source). If the Python module that comes with OpenCV on Windows is incompatible with your system architecture or Python version, see this page to obtain a pre-compiled (unofficial) module.

To ensure you have all the requirements installed, open a python interpreter, and ensure you can run import numpy and import cv2 without any errors.
