Closed Captioning
VEGAS® Pro software supports adding closed captions to video files and rendering those files as XDCAM HD and XDCAM HD422 MXF files. You can also add captions to video files and render as Windows Media Video for use in Windows Media Player.
TIP Another way to add subtitles to your video is to create text events from *.txt or *.csv files by using Insert Subtitles from File from the Insert menu.
