After making numerous attempts to render a 15 minute video using Vegas Pro v23, the final result was a 45 minute run time (15minute of intended video render / 30 minutes of additional render with no content). I even had trouble adding the aforementioned result (MPEG2 file)to the timeline (to trim the additional 30 minutes). Had to return to Vegas Pro v22 to complete the project. Any ideas why this rendered this way ?
