Dukat said:First you need to create two video tracks, then you need to insert text media on the higher track, with your video on the lower track.
After you have the two lined up, right click on the text media, go to "edit generated media" and then click on the "properties" tab. In the "background color" section you need to set the "A" field to '0'.
This will make the background transparent and the text will show through with the video under it
Hope that helps.
