You're getting inverted text? You mean upside-down? That shouldn't happen.
When you say HD, I'm assuming you mean 1920x1080 HD. (There are also 1440x1080 and HD Lite 1280x720.) If so, the Corner Pin settings of UL 850 400, UR 1070 400, LL -2000 1500 and LR 3920 1500 will work.
If what you're saying is that you're trying to get the text to roll down instead of up, that's something you can't do using the Roll/Crawl feature. In fact, it would be very difficult to do at all, as sort of a reverse Star Wars effect. Besides, your audience will be reading from the bottom of the paragraph up!
Hi Steve - thank you for the reply. I am using HD 1920x1080. The effect that I am trying to create is text appearing (small) in the middle of the screen and then rolling out to wide to the bottom of the screen so that it appears as if you are flying over the text as if it is appearing in the distance and rolling to you (somewhat like the star gate effect in the movie "2001" when Dave goes through the monolith and text and math symbols are scrolling by him). Is there a trick to make the text scroll in that fashion?
The text will be a series of one-liners with blank space between each of the lines, it will not be paragraphs. The reader will not get dyslexia while viewing the video
BTW - I use both of your PE books - Guide and Cool Tricks - they are very useful.
