That download are the sample scripts but NOT the API description.
As stated in the document "Vegas 4.0 learn to use the new features" on page 43 there should be a separate document "Vegas 4 Scripting API Summary". This should be in the "Extras" folder of the Vegas installation CD-ROM.
I have the download version - so no CD-ROM.
Where else can this document be found?
Any ideas?
VegasScriptAPI.html is part of the sample script download at the link I provided earlier. Open the zip file and you get 8 sample scripts, two "xml" files, and the VegasScriptAPI file.
At the time I downloaded it, there was a file called vegasscripts.exe! And this one is in fact slighty different from the file that is now there vegasscripts.zip.
