@marek11 View your video with your user. There wil lbe a special button near the border edge somewhere. Press and select type and drag and insert text.
@marek11 If you can tell me what OS you got it would be easier For Windows try downloading Windows Live Movie Maker or iMovie for Mac if you dont already have it, that could work for displaying basic text. Wait you're talking about an video right? Like an video of TPT? Not in the scene? Right?
