hi guys..
can someone help me creating a script which can change the alpha channel to Straight (Unmatted) of the selected event at its media level with one click.
thanks in advance.
Just take a look through my tutorials...
Thanks so much sir for giving me Idea....
using ScriptPortal.Vegas;
namespace Change_Alpha_To_Straight
{
public class EntryPoint
{
public void FromVegas(Vegas vegas)
{
// Loop through each track in the project
foreach (Track track in vegas.Project.Tracks)
{
// Only process video tracks
if (!(track is VideoTrack)) continue;
// Loop through each event on the track
foreach (TrackEvent evnt in track.Events)
{
// Check if the event is a video event
if (evnt is VideoEvent)
{
// Cast the event to a VideoEvent
VideoEvent videoEvent = (VideoEvent)evnt;
// Get the media from the active take of the video event
Media media = videoEvent.ActiveTake.Media;
// Ensure the media is valid and has video streams
if (media != null && media.HasVideo())
{
// Loop through media streams
foreach (MediaStream stream in media.Streams)
{
// Check if the stream is a video stream by its MediaType
if (stream.MediaType == MediaType.Video)
{
VideoStream videoStream = (VideoStream)stream;
// Set the alpha channel to 'Straight'
videoStream.AlphaChannel = VideoAlphaType.Straight;
}
}
}
}
}
}
}
}
}
@iEmby Best you try configure that script to toggle between Straight and Premultiplied, because some media content with an alpha channel shows cleaner with Premultiplied.
@iEmby, in this section:
public void InitializeModule(Vegas vegas)
{
myVegas = vegas;
CCM.MenuItemName = "My Test Custom Command";
}
Add the IconFile to use:
public void InitializeModule(Vegas vegas)
{
myVegas = vegas;
CCM.MenuItemName = "My Test Custom Command";
CCM.IconFile = "{path to my icon}";
}
However, I'm not seeing any icons at all in VEGAS Pro 22.
@jetdv I'm seeing icons with graphics that I created or installed years ago, but I'm having poor results with adding new graphics in Vegas Pro 22-122.
@john_dennis I'm talking about extensions, not scripts.
@john_dennis, I'm not seeing them for scripts either, though:
@john_dennis, I'm seeing them again after a reboot...
@jetdv I've analyzed this six ways to Sunday and now I'm more confused than I was at the beginning. The most reliable solution that I've found was opening the .png files in Classic Paint (Windows 11) and saving. This seems to work without regard to how I might have created the files.

@john_dennis the important line here is Color Space: RGBA
The images MUST have "transparency" to show. Often, I make my icons and then just make one pixel transparent to make sure it saves as RGBA out of the photo editor.
@jetdv That appears to be correct.
An Aside
It appears that Classic Paint in Windows 11 adds the Color Space parameter where none existed before:
That's probably why it always seemed to fix the problem.
@john_dennis your left image is a JPG. JPG doesn't support transparency which is why they need to be PNG files.
I understand. I made the PNG from the JPG in Classic Paint and the Color Space was changed to show RGBA where no actual transparency existed. The implication to me is that transparency doesn't have to be present, it just has to be possible based on the file parameters.
Sorry for semantisizing.

sir.. in the cases of scripts .. my icons are so smooth and perfect.
@iEmby Congratulations!
I'm currently running a Vegas 22 trial on top of an out of the box Windows 11 image which I dual boot to an in-place Windows 11 upgrade of my Vegas 21 image. I'm exploring changes that I would normally ignore in favor of getting things done. This article gave me comfort that I had not lost my mind completely.
