I'm trying to create open captions for a video I'm working on. When I go to add captions I'm only given a few options, none of which are the 'open caption' style I need. Additionally the option to add caption from the bottom 'new item' button is missing.
Sorry about that. You're close, though. Click the "Create new caption track" button to create a new Captions Track. Then, the UI should change noticeably. You can then click the "+" sign to create your first caption (see my screenshot). You might want to switch to the Graphics workspace to do all this, so that you can style the subtitle (Open Caption).
Click the "+" sign to create your first captionHope that helps.
