What tool are you using to export the regions? I use Excalibur and can have them named with a preset or just the region name. If you're using the "Batch Render" script, you may need to edit the script to get the naming exactly as you want. It all depends on HOW you are doing it. You could always write your own script:

Using Ctrl+R, there should be a dialogue box after rendering that includes a 'rename' button.

Alternatively, use the Loop facility (the little yellow in/out markers) to select the TL section to be rendered and use File/Render As to render to your wanted folder location along with the ability to name the render as you wish.

I use batch rending (Tools>Scripting>Batch Render) because it helps to render multiple segments at the same time. But I don't find any option there like "rename". Could you please show me with a screenshot?

CTRL+R:

But I've just realised that CTRL+R renders audio only - so that's not going to be of much help after all. Sorry about that.

However, CTRL+M will render the timeline - video and audio - to a new (higher) track. The area of the timeline render is defined by the Loop yellow markers (assuming that Loop is checked in the Render As window.

After hitting CTRL+M, the Render As window opens and the render becomes a conventional render where the destination folder and file name can be selected/named.

There is another method which may help using your current render method if the render is on the timeline. Simply R click the video event and select Properties. The top field of the Properties window is the 'Active Take Name' and, as it is a codable field, the file name can easily be renamed:

This method can also be used on the event in Windows Explorer (but not Vegas' Explorer window). If on the timeline, the listing of that event can also be renamed in Vegas' Project Media window (R click the event in Project Media and select 'Rename' which is about half way down the context menu..

Hoping that one of these methods will work for you.

@debojitacharjee Then you need to open that script "C:\Program Files\VEGAS\VEGAS Pro 21.0\Script Menu\Batch Render.cs" and change the code where it sets the name of the region. Find this line:

                    String regionFilename = String.Format("{0}[{1}]{2}",
                                                          filename,
                                                          regionIndex.ToString(),
                                                          renderItem.Extension);

Try changing "filename" to "region.Label"

Then, if you don't want a number appended, change {0}[{1}]{2} to {0}{1} and get rid of regionIndex.ToString(),

The Batch render v2 script can be used for this. The latest version is in page 3 of this thread, I believe:

your script is good but it won't be useful for me because I need a solution to render the video files on the timeline without renaming them. There could be 100s of files and manually renaming them won't be possible. So I need a way to get the rendering done by saving the rendered files with the default file names.
