I need to separate the audio tracks from the video. So far no luck. Editing for years, just new to Vegas. I think part of my roadblock is having to learn Sony terminology. Thanks for any help.
Click on either one and press U to "ungroup". You can then slide one around without the other following, or delete one and the other remains. Is that what you're after?
Another option to temporarily ungroup events; "Options> Ignore Event Grouping" (short cuts: Ctrl+Shift+U or click icon in toolbar) or... assign your own keyboard shortcut in "Options> Customize Keyboard".
