Hi
You have your video clip on the timeline and you have clicked on the "Add Test" tab.This opens the text entry window. This window may have a default colour depending on the options mentioned below.
In the centre at the top of the window is a block of three options.
The top option allows you to add aText outline and the slider position determines the size of the outline. Clicking the square allows you to select an outline colour.
The middle option allows you to have
"Full Background" The text will appear in a full frame of the selected colour.
"Text Background" The text will appear in a transparent frame but will have a background of the selected colour
"Editor Only" The text will appear with the editor frame only coloured. When on the timeline it will be on a transparent frame
So to put your text onto your clip so the it appears against your clip...
Click "Add Text"
Select your Font, size and colour.
Enter your text.
Select "Editor Only" and a suitable colour to contrast with the text so you can read it. (It won't show on the timeline)
Add Shadow or Outline as required
Add Justification (Right Centre Left) and basic position for the text (Top Middle Bottom)
Add scrolling if required
Your text will now appear on Video Track 2 (The Overlay track) You can select the text image from the Clip window image bin and re-edit the text and its attributes if they are not what you want.
