Hi,

Not used Vegas in an age, but if you want to export the same as the Vegas properties “1920×1080” which would be your preview, just select it in your export size, or do a custom export.

But the best thing to do would be to change your timeline / vegas settings to match that of your source footage and export ratio, check your cut and output at the native size.

What is the output for?
