Anwar, I already replied to you, but just in case here it is again:
sometimes there is this difference between "in editor" and "in video" rendering, this is due to the fact that different browsers render text slightly different from each other.
You can try to "fix" it by converting text to shapes. Right click on the text and select this action. See this screenshot how to do that: http://cl.ly/1w0A2R2r2D0E
After that you may need to adjust the text a bit, but it will look exactly the same in all the browsers and in video.
