  FourPoints Script Not Working

  Posted by Bill Cortez on February 19, 2009 at 5:11 am

  I’m using Vegas Pro 8c and I can’t get Edward Troxel’s FourPoints script to run (I saved it as a .cs file, I also tried .js). I get an error message that says: “Exception thrown by message called.”
  In the details it says in part: “System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.ApplicationException: Failed to add envelope point (point may already exist at that location).
  at Sony.Vegas.EnvelopePoint.AddSelf(IEnvelopeOwner owner, EnvelopeType type)”

  I can run the scripts that came with the installation. Thanks, Bill.

  > Failed to add envelope point (point may already exist at that location).

  Do you have an envelope point at the location already? I’m not familiar with the script but I assume you must first make a timeline selection and then it creates a 4-point envelope within the selection. Perhaps you didn’t make a timeline selection first? If you can point me to the script, I can take a look for you.

  Here’s the current version of that script for Vegas Pro 8.

  /**

  using System;
  //using System.IO;
  //using System.Windows.Forms;
  using Sony.Vegas;

  public class EntryPoint
  {
  Vegas myVegas;

  public void FromVegas(Vegas vegas)
  {
  myVegas = vegas;

  //Change this line to change the distance between the points
  Timecode FPDist = new Timecode("00:00:01:00");

  foreach(Track track in myVegas.Project.Tracks)
  {
  //Now check for Volume Envelope
  if (track.IsAudio() && track.Selected)
  {
  // Find the volume envelope on this track - add if needed
  Envelope VolEnv = FindEnvelope(track, EnvelopeType.Volume);
  if (null == VolEnv)
  {
  VolEnv = new Envelope(EnvelopeType.Volume);
  track.Envelopes.Add(VolEnv);
  }

  double ClipVol = VolEnv.ValueAt(myVegas.SelectionStart);
  //Now set the points
  SetPoint(VolEnv, myVegas.Transport.LoopRegionStart, ClipVol);
  SetPoint(VolEnv, myVegas.Transport.LoopRegionStart - FPDist, ClipVol);
  SetPoint(VolEnv, myVegas.Transport.LoopRegionStart + myVegas.Transport.LoopRegionLength + FPDist, ClipVol);
  SetPoint(VolEnv, myVegas.Transport.LoopRegionStart + myVegas.Transport.LoopRegionLength, ClipVol);
  }
  }
  }

  private Envelope FindEnvelope(Track track, EnvelopeType etype)
  {
  foreach(Envelope env in track.Envelopes)
  {
  if (env.Type == etype)
  {
  return env;
  }
  }
  return null;
  }

  private void SetPoint(Envelope menv, Timecode PLoc, double PVal)
  {
  EnvelopePoint a = menv.Points.GetPointAtX(PLoc);

  if (a == null)
  {
  a = new EnvelopePoint(PLoc, PVal);
  menv.Points.Add(a);
  }
  else
  {
  a.Y = PVal;
  }
  }

  }


  Just save it as “FourPoints.cs” and it should do the job for you. You do need to have a selection area (it will still work even if you don’t but won’t give you what you want) and a selected audio track.

  Thanks Ed, I had the audio track and the event selected, but I didn’t make a selection area–that did the trick. Cool, your script will save me a lot of time editing, appreciate it a lot. Bill.
