FitCD is designed for TV output. Most TVs don't show the image all the way to the edge, so if you don't add borders to the video the edges will be cut off. It also resizes the video to SVCD standard (480x480 for NTSC, 480x576 for PAL). This changes the aspect ratio of the encoded film, but it will be corrected on playback.
