Personally, you should use Sony Vegas (for chroma keying, subtitles, advanced editing, and so on). However you do have to buy it, so it may not be what you want. However, you could download it and use a Keygen to crack it so you don't have to pay for it. Or you could use a free trial until you're willing to pay for it.
