VEGASPython for Developers

Introduction

VEGAS Pro allows the control of the application via scripting. Scripting provides access to the internal data structures in VEGAS projects that allows you to automate things that you might normally do via the GUI. VEGAS uses the .NET framework to provide its scripting interface. VEGAS can execute C#, JScript, and Visual Basic script files directly.

PYTHON is an easy to learn powerful programming language that is more and more used for scripting of applications. In the 3D and video editing area some application use already PYTHON for scripting.

Goal of this VEGAS extension is to provide an easy access to VEGAS scripting using PYTHON.

The extension provides two options:

  • an interactive dockable VEGASPython Window
  • executing Scripts located in a specific folder and integrate them into the VEGAS User Interface like other C# Scripts

With this tutorial I would like to provide for beginners the know-how to write scripts using VEGASPython. This includes an introduction to Python progamming and to the main concepts of the VEGAS interface.

The FAQ describes the usage of VEGAS scriting for C#. The examples can be easily transfered to VEGASPython. An updated FAQ for VEGASPython will follow soon.

VEGAS Scripting API: direct link vegas_scripting_api.zip

The API describes the C# definition of all VEGAS structures and items that can be accessed. All these items can be accessed in the same way in VEGASPython.

VEGASPython Interactive Window

VEGASPython includes an interactive window. VEGASPython interactive window is activated via the 'View' / 'Extensions' tab.

A VEGAS dockable window opens. The window can float over VEGAS or can be integrated into the VEGAS layout as any other VEGAS window.

The VEGASPython window shows two textboxes:

- Input PYTHON Comands - Output

and a menu with two items „File“ and „Execute VEGASPython Script“.

Python comands are entered in the textbox „Input“. Several lines can be entered one after each other. It is possible to copy a complete PYTHON Script from another editor via CTRL+C and CTRL+V. The PYTHON commands will be executed by clicking on the menu „Execute VEGASPython Script“.

All output from PYTHON print statements and all error messages will be shown in the „Output“ textbox.

VEGASPython is based on Python 3.7.3 and PythonNet.

The VEGAS API can be accessed directly by using the build-in variable „pyVEGAS“. All VEGAS API items are available.

Examples


Example for a simple script that can be used in the interactive window:

  import clr
  clr.AddReference('ScriptPortal.Vegas')
  import ScriptPortal.Vegas
  from ScriptPortal.Vegas import *
  # adapt this value to your needs
  maxLength = Timecode.FromString("00:00:04:00")
  # Go through the list of Tracks
  for track in pyVEGAS.Project.Tracks:
      for evnt in track.Events:
          if (evnt.Selected):
              dLength = evnt.Length
              if dLength > maxLength:
                  dLength = maxLength
              dStart = evnt.Start
              evnt.AdjustStartLength(dStart, dLength, True)

A script that is used as an extension needs to be included in a function FromVegas. See example below.

  import clr
  clr.AddReference('ScriptPortal.Vegas')
  import ScriptPortal.Vegas
  from ScriptPortal.Vegas import *
  def FromVegas(pyVEGAS):
      # adapt this value to your needs
      maxLength = Timecode.FromString("00:00:04:00")
      # Go through the list of Tracks
      for track in pyVEGAS.Project.Tracks:
          for evnt in track.Events:
              if (evnt.Selected):
                  dLength = evnt.Length
                  if dLength > maxLength:
                      dLength = maxLength
                  dStart = evnt.Start
                  evnt.AdjustStartLength(dStart, dLength, True)
