Sorry for my bad english.
I have a program (CamStudio) for recording screen. This program will record screen in hd. Then, I wanted that this video contains the text. So, I add text in windows movie maker. And I save this movie in hd. But, this movie isn't in hd (the size of the video is also different). What I must do!
Here's the videos: Original video (made by CamStudio) (size: 3,65 MB) Video after editing in window movie maker (size: 411 KB)
