Regardless of scripting, there is a convenient way in Vegas to unify FPS. Set the project framerate to 25fps in advance, then right-click the files in Project Media and select "Add at Project Framerate", which will make the files match the project framerate. However, for 60fps files, it will also be stretched to 25fps instead of 50fps.

And this is exactly what I don't want. If the video is 60fps, then I need 50fps. Not 25fps. That's why I need that script.

It converts the framerate of the selected video events (and other events in their own groups) into the result you want.

0.6 is the threshold to determine whether to *2, you can change to another suitable value.

And this is exactly what I don't want. If the video is 60fps, then I need 50fps. Not 25fps. That's why I need that script.

I tried it now.
It's great that the script will automatically extend the events.

Is it possible for a script to sequence events without Transitions?

Please make one change.
Your script changes even an event that has 50fps to half the speed.

Please ignore 50fps as well as 25fps.

Thank you very much.
Good job!!!!

Please make one change.

Yeah I just found I made a mistake, please change the threshold to 0.6 (it was 0.47 before), it should be greater than 0.5.

Now it calculates the offset for events later in the same track.

Tried.

If I only have 30fps events, then the transition is always done.

If I only have 60fps, this is what happens:

Please use the latest version, I just made a mistake and have corrected it 20 minutes ago.

@zzzzzz9125

update: If you mark multiple 60fps events, some will not convert to 50fps.

I have updated your script now.

Now the same thing happens for both 60fps and 30fps - some events don't convert and both look like this:

I'm trying on the VP21 b108 version

@zzzzzz9125

Cool. Now that's perfect!!!! You saved me several hours of time!!! Thank you very much!

The goal of this script is to unify the speeds at the beginning before editing, so that some events are not jerky in the rendering. In addition, with synchronized audio!

If you find my answer helpful, you can set it as a "Solution". 👏

Thank you so much zzzzzz9125 for a great job!!!! You are a god!

Use:
- Before the cut itself
- only on marked events in the Timeline
- synchronization with sound
- automatically extends events
- if you mark multiple events, they will be arranged automatically one after the other without transitions and spaces
- 23,29,30fps will change to 25fps
- 59 and 60fps will change to 50fps
- if you have the project set to a different fps, the script should adapt.

The goal of the script is that the resulting video is not choppy at times.

Hi.
I ask you for one more correction.

The script works great, I just need to trim the last frame of the events according to the project.

Let me explain:
The project is 25 frames per second.
Events that are 60fps will change the script to 50fps and extend. That's great. This is how it's supposed to work.
But the events are not aligned in the timeline to the 25fps project, but always extend a bit more. Which is strange, but it's true.
When events shorten with Auto Ripple on, I get a gap between events.

I am asking for a modification so that when changing the events to 50fps or 25fps (depending on whether the video is 60 or 29fps), they are shortened at the end to match the project settings.

Do you understand my request please?

0.833 is not enough and 0.834 is too much.
0.8335 would be ideal, but Vegas can't do that.

@pierre-k It's due to the fact that you have "Quantize to Frames" enabled and editing will round to the exact frame position in the project, while my script doesn't.

Here's a corrected version:

using System;
using System.Collections.Generic;

using ScriptPortal.Vegas;  // "ScriptPortal.Vegas" for Magix Vegas Pro 14 or above, "Sony.Vegas" for Sony Vegas Pro 13 or below

namespace Test_Script
{
    public class Class
    {
        public Vegas myVegas;
        public void Main(Vegas vegas)
        {
            myVegas = vegas;

            foreach (Track myTrack in myVegas.Project.Tracks)
            {
                if (myTrack.IsVideo())
                {
                    List<VideoEvent> eventList = new List<VideoEvent>();
                    foreach (TrackEvent evnt in myTrack.Events)
                    {
                        if (evnt.Selected)
                        {
                            eventList.Add((VideoEvent)evnt);
                        }
                    }

                    if (eventList.Count == 0)
                    {
                        continue;
                    }

                    Timecode offset = Timecode.FromNanos(0);

                    foreach (VideoEvent vEvent in eventList)
                    {
                        double rateSave = vEvent.PlaybackRate;
                        double rate = myVegas.Project.Video.FrameRate / ((VideoStream)vEvent.ActiveTake.MediaStream).FrameRate;
                        if (rate < 0.6) {
                            rate *= 2;
                        }
                        Timecode lengthSave = vEvent.Length;
                        vEvent.Length = Timecode.FromFrames((long)(Math.Round(lengthSave.Nanos * myVegas.Project.Video.FrameRate * rateSave / rate / 10000000)));
                        vEvent.PlaybackRate = lengthSave.Nanos * rateSave / vEvent.Length.Nanos;

                        vEvent.Start += offset;

                        if (vEvent.IsGrouped)
                        {
                            foreach (TrackEvent groupEvent in vEvent.Group)
                            {
                                if (groupEvent == vEvent)
                                {
                                    continue;
                                }
                                groupEvent.Start += offset;
                                rateSave = groupEvent.PlaybackRate;
                                groupEvent.PlaybackRate = vEvent.PlaybackRate;
                                groupEvent.Length = Timecode.FromNanos((long)(groupEvent.Length.Nanos * rateSave / groupEvent.PlaybackRate));
                            }
                        }
                        offset += vEvent.Length - lengthSave;
                    }
                }
            }
        }
    }
}

public class EntryPoint
{
    public void FromVegas(Vegas vegas)
    //public void FromVegas(Vegas vegas, String scriptFile, XmlDocument scriptSettings, ScriptArgs args)
    {
        Test_Script.Class test = new Test_Script.Class();
        test.Main(vegas);
    }
}

The script now rounds off the end of the event to the project frame position. You can also change Math.Round() to Math.Floor() or Math.Ceiling(), depending on the rounding method you want to use.

@zzzzzz9125

Thank you.
Now it does this for me:

I probably need to change the sequence of actions in the script. That?
1. fps change
2. shortening of events according to project settings
3. and finally - remove spaces.

I tried to create a script with AI but it still shows me an error table. I'm not familiar with scripts at all. I'm glad you're helping me.

now almost every event has a different speed.
0.834
0.826
0.840
0.836

I need:
1. so that the speed is the same 0.833.
2. to cut the event at the end. She didn't speed up or slow down.

3. and finally - remove spaces.

@pierre-k Are you sure these events are tightly coupled before you run the script? Are these gaps really not created due to "Quantize to Frames"? I mention it because when it's enabled and you add footage that does not match the project framerate, it quantizes your edit frame to the project frame position, which may create gaps. The previous script does not change the relative positions between events. They should be as wide as they were before the script was run.

Of course, we can also close the gaps between all events in advance, using the following code:

for (int i = 0; i < eventList.Count - 1; i++)
{
    if (eventList[i+1].IsGrouped)
    {
        Timecode tc = eventList[i+1].Start - eventList[i].End;
        foreach (TrackEvent ev in eventList[i+1].Group)
        {
            ev.Start -= tc;
        }
    }
    else
    {
        eventList[i+1].Start = eventList[i].End;
    }
}

now almost every event has a different speed.
0.834
0.826
0.840
0.836

I need:
1. so that the speed is the same 0.833.
2. to cut the event at the end. She didn't speed up or slow down.
