... batch render events from timeline (or files from folder) and get the filename/path from the event.

I think you probably know that, in Vegas terminology, and event is an object on the timeline, but that many events can come from the same file name.

I am not entirely sure what you want to do, but here is a jscript script that I wrote which does part of what you asked for. However, as noted in the comments at the top of the script, if you have multiple events on the timeline that come from the same media file, this script (as written) will result in duplicate file names. You could easily add some code that appends a counter number to the end of each file name in order to avoid that duplication.

This script creates and names the regions. You can then simply use the Batch GUI script included with Vegas to actually do the rendering.

/**

 * This script will add regions for all events on the selected track,

 * and name those regions to the event's media file name.

 *

 * If more than one event comes from the same media, this will result in 

 * duplicate region names.
