@relaxvideo To show the error message:

try
{
    Subclip clip = myVegas.Project.MediaPool.CreateStereo3DSubclip(mediaLeft, mediaRight);
} catch (System.Exception ex) { myVegas.ShowError(ex); }

I know very little about 3D, so I'm not quite sure how to make it work properly...

@relaxvideo How do you expect it to work?

In the current script, you need to select two media in Project Media window. It creates a new Stereo 3D SubClip for these two media.

Wow, on project media window it seems working!

But 3D videos in separate left-right source format are not paired in project media window, because we need to syncronize first on the timeline. So i select 2 events on the timeline which is on 2 different tracks. I hope these can be also paired with your script :)

@relaxvideo I can't make it work properly..

The following script creates a Stereo 3D subclip from the media of the selected two events on the timeline, but it cannot do pairing based on the event offset.

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using ScriptPortal.Vegas;

namespace Test
{
    public class TestClass
    {
        public Vegas myVegas;
        public void Main(Vegas vegas)
        {
            myVegas = vegas;

            if (myVegas.Project.Video.Stereo3DMode == Stereo3DOutputMode.Off)
            {
                myVegas.ShowError("Not Stereo 3D Mode.");
                return;
            }

            foreach (Media m in myVegas.Project.MediaPool.GetSelectedMedia())
            {
                if (m is Subclip)
                {
                    Subclip s = m as Subclip;
                    MessageBox.Show(s.TimecodeIn.ToString() + "\n" + s.TimecodeOut.ToString());
                    return;
                }
            }

            List<VideoEvent> selectedEvents = new List<VideoEvent>();
            foreach (Track trk in myVegas.Project.Tracks)
            {
                if (trk.IsVideo())
                {
                    foreach (TrackEvent ev in trk.Events)
                    {
                        if (ev.Selected && ev.ActiveTake != null && ev.ActiveTake.Media != null)
                        {
                            selectedEvents.Add(ev as VideoEvent);
                        }
                    }
                }

            }

            if (selectedEvents.Count < 2)
            {
                return;
            }

            VideoEvent evLeft = selectedEvents[0], evRight = selectedEvents[1];

            if (myVegas.Project.MediaPool.CanCreateStereo3DSubclip(evLeft.ActiveTake.Media, evRight.ActiveTake.Media))
            {
                try
                {
                    Timecode startOffset = evLeft.ActiveTake.Offset - evRight.ActiveTake.Offset - evLeft.Start + evRight.Start;
                    Subclip clip = myVegas.Project.MediaPool.CreateStereo3DSubclip(evLeft.ActiveTake.Media, evRight.ActiveTake.Media);
                    //clip.Start = startOffset;
                    VideoStream vs = clip.GetVideoStreamByIndex(0);
                    if (vs != null)
                    {
                        Timecode offset = evLeft.ActiveTake.Offset;
                        Take tk = Take.CreateInstance(myVegas.Project, vs, true);
                        evLeft.Takes.Add(tk);
                        tk.Offset = offset;
                        evRight.Track.Events.Remove(evRight);
                    }
                } catch (Exception ex) { myVegas.ShowError(ex); }
            }
        }
    }
}

public class EntryPoint
{
    public void FromVegas(Vegas vegas)
    {
        Test.TestClass test = new Test.TestClass();
        test.Main(vegas);
    }
}

In these codes, you will find one line:

//clip.Start = startOffset;

According to my tests, it seems that the offset of the Stereo 3D subclip is determined by Subclip.Start.

If you uncomment it, Vegas Pro will not allow you to execute this line. The Start of a subclip should only be specified at the moment of creating the subclip.

However, when we create the Stereo 3D subclip, we use this:

Subclip clip = myVegas.Project.MediaPool.CreateStereo3DSubclip(evLeft.ActiveTake.Media, evRight.ActiveTake.Media);

This method does not allow you to set offsets. There's no other way to directly create Stereo 3D subclips from timeline events either. So for now, it seems impossible to do it.
