Looking to find a converter for my video formats to Apple TV Audio MP3, M4A.

[FONT=&quot]Hello everybody, there are a few software available for video formats to Apple TV Audio MP3, M4A. I have used them but they are not good at editing features. I do sometimes want to remove a particular clip and that’s where I face problems. The conversion speed is also not great but I am more concerned about the editing thing.[/FONT]
