Exporting and sharing projects
When you're finished editing your VEGAS® Pro project—or when you want to see it in its final form—you can use the Render As dialog to convert your project to another format and create a single file on your hard drive.
From the File menu, choose Render As to display the Render As dialog.
When you're finished editing your VEGAS® Pro project—or when you want to see it in its final form—you can use the Save it to my hard drive destination in the Make Movie wizard save your project as a single file on your hard drive.
If you need access to more rendering options, click the Advanced options button to open the Render As dialog.
When you render your project, the project file is not affected (overwritten, deleted, or altered) during the rendering process. You may return to the original project to make edits or adjustments and render it again.
If you've prerendered your project, those prerendered sections can be used for your final render when the destination formats match.
