If you look at the cost of the various media converters that are out there they are not cheap and they don't do that much so why bother paying for one when there are some for free.For example one of the free softwares available is called mediacoder.This software has the most features I have ever seen and all for free
Some of its features include;
- Convert to and from many audio and video compression formats and re-multiplex into various container formats in batches
- Full control over transcoding parameters, you can learn about audio/video encoding and play with various codecs
- Strong decoding capability for partial or corrupted contents
- Simplified UI for popular mobile devices (e.g. PSP, iPhone/iPod)
- Fully standalone, no dependance on system codecs/splitters
- Extension (scripting language) infrastructure to expand user interfaces and improve user experience
