Video Edit Magic's text effect currently does not support adding multiple text areas on the video. However, you can use the Chroma Key Color (Transparency) transition to achieve such an effect.
Create an image in Microsoftr Paint or your favorite image editor with the same width and height as your Video Edit Magic project dimensions. Change the background color of the image to solid Green or Blue. Add text to this image.
Now in Video Track 1 add the video. On Video Track 2 add the image you just created. From the Video Transition tab, add the Chroma Key Color transition in the Transition Track between the video and image. From the transition's properties, set the color that you want to make as transparent to Green or Blue.
