it works... thank you so much sir.. u r just genius 💯💯

@iEmby sometimes it's best to "think simple". Need an event on a different track? Just change the track! No need for complicated duplicating of an event to another track and then removing it from the existing track (unless you need multiple copies of the event)... Changing the track seemed the simplest option in this case.

Thank you for that. You know, if you eliminate the condition that the events have to be the same length, you can shuffle/swap events of different lengths. If you eliminate the condition that they need to be video events, you can swap audio events. If you select a video and an audio event by mistake, the system will give you an error message. I suppose if you aren't lazy, it would be desirable to test for that condition beforehand and display a friendlier message if not the same type of event.

Any suggestions?

@jetdv i know sir u are always right. i am not perfect in coding yet. still learning. Thanks for every help.

@Robert Johnston u r right sir, i have those options too. let me check first then will share it in script collection thread

@Robert Johnston, yes, it would be good to test if the target track is the same type as the media and provide the proper error message. I just added the swap three lines to the original code.

@jetdv @iEmby Hi, can you share the full script inc header etc. pls, I tried this yesterday with two clips the same length, I see you've added to it 👍 but I keep getting the 'message missing' msg, I guess I'm missing something in the script or just doing it wrong.

Quite often when I'm editing I'll add text or an image etc. If I'm happy with that I'll 'Render to a new track' then swap those parts over before final render, selecting the orig & the new rendered event then clicking a script to swap them over would useful, In the past (NVENC) render would place images or text in all sorts of places, so doing this keeps the timeline clean & final render goes quickly without a hitch, there's nothing worse then waiting 20mins or whatever while it renders to find a picture or text isn't behaving as it should. 👍

@Gid, iEmby included the full script at the top. I just changed:
 

        SwapEvents(event1, event2);
    }

    private void SwapEvents(TrackEvent event1, TrackEvent event2)
    {
        // Capture initial properties
        Timecode start1 = event1.Start;
        Timecode start2 = event2.Start;

        Track track1 = event1.Track;
        Track track2 = event2.Track;

        // Add a new event at start2 for event1's media
        TrackEvent newEvent1 = DuplicateEvent(event1, track2, start2);
        track2.Events.Add(newEvent1);

        // Add a new event at start1 for event2's media
        TrackEvent newEvent2 = DuplicateEvent(event2, track1, start1);
        track1.Events.Add(newEvent2);

        // Remove original events
        track1.Events.Remove(event1);
        track2.Events.Remove(event2);
    }

    private TrackEvent DuplicateEvent(TrackEvent originalEvent, Track targetTrack, Timecode startTime)
    {
        // Create a new event
        VideoEvent newEvent = new VideoEvent(startTime, originalEvent.Length);

        // Copy takes from original event to new event
        foreach (Take take in originalEvent.Takes)
        {
            newEvent.AddTake(take.Media);
        }

        // Add the new event to the target track
        targetTrack.Events.Add(newEvent);

        return newEvent;
    }

to:

        Track track1 = event1.Track;
        event1.Track = event2.Track;
        event2.Track = track1;
    }

@jetdv Thanks but sorry I'm confused now, in the second comment you said 'That seems to be a LOT more complicated than what you need', & posted a shorter version, so I i cut his orig down but kept the 'using' using .. part at the top, now you post another different section of that script 🤯 I can't piece together this jigsaw puzzle I've tried a few combinations of the bits posted & still get the error msg🤷‍♂️

@Gid Yes, look at my last post to you that shows what I replaced with those three lines! I replaced about 40 lines of code (which also contained two subroutines) with three lines of code. This would be the "new" version:

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

public class EntryPoint
{
    public void FromVegas(Vegas vegas)
    {
        // Ensure exactly two video events are selected
        List<TrackEvent> selectedEvents = new List<TrackEvent>();
        foreach (Track track in vegas.Project.Tracks)
        {
            foreach (TrackEvent trackEvent in track.Events)
            {
                if (trackEvent.Selected && trackEvent.IsVideo())
                {
                    selectedEvents.Add(trackEvent);
                }
            }
        }

        if (selectedEvents.Count != 2)
        {
            MessageBox.Show("Please select exactly two video events.");
            return;
        }

        // Ensure the selected events are on different tracks and have the same length
        TrackEvent event1 = selectedEvents[0];
        TrackEvent event2 = selectedEvents[1];

        if (event1.Track == event2.Track)
        {
            MessageBox.Show("Selected events must be on different tracks.");
            return;
        }

        if (event1.Length != event2.Length)
        {
            MessageBox.Show("Selected events must be of the same length.");
            return;
        }

        // Swap the events by moving them to the other event's timecode
        Track track1 = event1.Track;
        event1.Track = event2.Track;
        event2.Track = track1;
    }
}

It still has all of his selecting of the proper event code but the "swapping" code is shortened to just swap the tracks instead of everything else the original code was doing.
