Because I'm picky and a near-perfectionist, I use Ulead Video Editor, a video program to edit the appearance. It loads the srt file and then I edit how it fades, colors, shadows, glows, fonts, etc. I can also move the words around to where I want it and add a watermark in the video. All in one Only con is that I can't really do karaoke but it looks like aegisub does that.
