I came back to this issue again just to see if any new functionality was added. I actually found what "should" be a way to do this. But I'm getting an error.

There is a way through the baselist parent class to CopyTo all of the items in the list (in this case, the source Effects chain) to an Array. Then loop the array and insert the copies of the Effects into the target effects chain. Should work, and nearly does. But again, I'm getting an error on inserting the effects into the target.

Following is a script that's intended to copy track-level fx chain to each clip on the track. Everything works up to where I insert the copied Effect object into the target clip's Effects list. I get a weird error that says "System Argument Exception: Unknown effect plug-in". But if I show the effect plug-in name on the Effect object being copied, it looks fine. Also, if I create a new Effect using the plug-in name from the track-level object, it works and adds the correct effect type (except that's not what I want, I want the source effect, not a new effect).

Please take a look at this code and tell me if I'm just doing something wrong. I can't see anything that I could do differently.

To test, create a track with a few video clips. Add at least one effect at the track level. You should get an error. But comment the failing line and un-comment the line below it. It should work (at least create the same, but new default, named effects on the clips that were on the track level). It says when it fails that it doesn't recognize the plugin. But I can create a new effect using that plugin's name, and it works. Am I missing something obvious?

Thx.

import Sony.Vegas;
import System.Windows.Forms;

for ( var track in Vegas.Project.Tracks )
{
if (track.MediaType == MediaType.Video)
{
if ( track.Selected )
{
if ( track.Effects.Count > 0 )
{
for ( var evnt in track.Events )
{
var fx : System.Array = System.Array.CreateInstance(System.Object, track.Effects.Count);
track.Effects.CopyTo( fx, 0);
var fxEnum : Enumerator = new Enumerator(fx);
var i = 0;
while ( !fxEnum.atEnd() )
{
evnt.Effects.Insert( i++, fxEnum.item() ); // fails with "unknown effect plugin" (????)

//##### [following line works... but I want to copy the track effect, not a new effect] ######
//##### evnt.Effects.Insert( i++, new Effect( fxEnum.item().PlugIn ) );

fxEnum.moveNext();
}
}
}
}
}
}

Anything new on this issue?
