image and clip automation for new media added to project and timeline

[John Rofrano]

You could script the last couple of steps after you import the image sequence to make it one click but you need to know how to program in C#, VB, or JavaScript to write a script. I could write you a script to do this unless you want to try and tackle it yourself.

Did you check already the Vegas production Assistant to quickly set up new projects?

If you don’t mind scripting some of this that would be awesome. I don’t know how to script.

Thanks for the Production Assistant suggestion I will check that out also.

oh and i’m currently using vegas 8 Pro.

Here is a script that performs the procedure you explained:

1. Disable resample
2. Set playback rate to 2.0
3. Disable looping
4. Add velocity envelope at 200%
5. Adjust length to 25%

I don’t know why you set the playback to 2x and then add a 2x velocity envelope. Why not just set the playback to 4x? (it’s the same thing)

Anyway, here is the script: (save is at AdjustPlayback.cs in your Script Menu folder.)

/**
 * Program: AdjustPlayback.cs
 * Description: This script will change the playback rate of the selected events
 * Author: John Rofrano

using System;
using Sony.Vegas;

class EntryPoint
{
    public void FromVegas(Vegas vegas)
    {
        foreach (Track track in vegas.Project.Tracks)
        {
            if (track.IsVideo())
            {
                foreach (VideoEvent videoEvent in track.Events)
                {
                    if (videoEvent.Selected)
                    {
                        videoEvent.ResampleMode = VideoResampleMode.Disable; // disable resample
                        videoEvent.PlaybackRate = 2.0; // double the playback rate
                        videoEvent.Loop = false; // turn off looping

                        // create a velocity envelope
                        Envelope velocityEnvelope = videoEvent.Envelopes.FindByType(EnvelopeType.Velocity);
                        if (velocityEnvelope == null)
                        {
                            velocityEnvelope = new Envelope(EnvelopeType.Velocity);
                            videoEvent.Envelopes.Add(velocityEnvelope);
                        }

                        // get the default point and change it 2.0
                        EnvelopePoint velocityPoint = velocityEnvelope.Points[0];
                        velocityPoint.Y = 2.0;

                        // adjust the event length to 1/4 it's original size
                        videoEvent.Length = new Timecode(videoEvent.Length.ToMilliseconds() / 4.0);
                    }
                }
            }
        }
    }
}

most of my clips I change the speed on at different points to sync the events in the video to points in the audio. I could do 4x + add a velocity envelop and set at 100%, or 2x + 200%. I assume the resulting quality of the video will be the same?

Thanks for the script, I will try it out this weekend. The commenting is very helpful also, thanks.

Another question: is their such a thing as an audio velocity envelope that will work similar to the video version?

[John Rofrano]

Yes, either way the quality should be the same. I kinda thought you might be changing the velocity so using both makes sense.

As for audio, no there is no velocity envelope equivalent. 🙁
