Well after all my research the only things I've come up with is this:

Using Tmpeg encoder you can goto settings advanced and double click on the noise reduction and sharpen edge filters and that will improve the quality slightly.

The other software I've found that the professionals use is called Final Cut Pro. I haven't tested this yet as it is a 1000 dollar product and it only works on a macintosh.

If anyone else has any ideas please let me know.
