I have some footage where the audio is sometimes a little muffled and there is background hiss and hum that I'd like to get rid of. It's mostly sections of lectures and training related work stuff shot on my mobile phone. I would really like to be able to reduce the background hiss and improve the audio quality if I could. I would also like to be able to insert subtitles to the videos if possible.
I have a Mac OS and a Windows 7 computer so either platform is fine. I am happy to pay if it gives me the results I want but I haven't got a clue where to start. Are programmes such as SONY Vegas Movie Studio HD 11 Platinum Suite - for PC Deals | Pcworld or AVID Studio Deals | Pcworld the kind of thing I should be looking at purchasing?
