I am glad to announce the release of VEGASPython 1.0 including a new feature VEGASSceneDetect.
https://www.hlinke.de/dokuwiki/doku.php?id=en:vegas_python_download
For users VEGASPython is now easy to install and behaves similar to other VEGAS scripts (only difference: they are located under tools/Extensions and not under tools/Scripts)
The main new feature for users is VEGASScenedetect:
VegasSceneDetect analyses video clips either in the mediapool or on the timeline and determines scene changes. At each scene change detected VegasScenedetect either cuts the clips or creates a subclip. VegasScenedetect can be configured to your needs
For developers VEGASPython provides more new features:
- 
VEGASPython is now based on PYTHONNet and CPython - Full compatibility with standard CPython packages and modules - Python 3.7 , openCV and NumPy are already included 
- you can use your own Python installation 
- you can use any Python editor that supports CPython 
- Debugging of Python code with debuggers that support debugging embedded python is possible (e.g. WING Python IDE) 
- VEGASPython scripts behave like Python modules and are imported like Python modules" 
- reloading of modules is supported to avoid restarting of VEGAS after every change 
- configurable post and pre commands for debugging scripts 
- call VEGASPython scripts with Vegas from the commandline 
 
Very much thanks to Jan @xjirj22, Peter_P (somehow the @ does not work for your account) and @Former user for beta testing the solutions.
