Hello there!

I'm from Germany so please excuse me if my english isn't very well. I currently work on something for my university. I'm gonna right down the process of converting an HD .mkv file to an iTunes friendly .m4v. The goal will be to have a file at the end which can be played on most Apple devices. So when there's one 5.1 audio track as a DTS or AC3 file in the mkv I want to have one 5.1 AAC audio track and one in stereo for the mobile devices. In the last two days I've been looking around for the best options and encoders in this forum and in the wiki, but I'm not quite sure what to use and what's even more important: why I should use that?

For this process I'll use a mac. I've read that the Nero Encoder give the best results but since it doesn't excepts .dts or .ac3 files I don't know what I could do. Should I convert the .dts file f.e. first into another format so that NeroAAC would recognize it? Wouldn't that mean a loose of Quality? That's by the way also a very important thing for my work. To know what would be the best options in the encoder and to know how big the quality loss could be etc.

I hope you can point me into some directions and tell me something relevant for my topic. Have a good night everyone!

OK thanks for that. What I'm not getting is how can 384 kbps in VBR be as good as 1500 kbps in CBR? I don't really know what to use right now because I didn't really understand what's behind this codec and the idea of a VBR. My aac file out of a 1510 kbps DTS track goes from about 1043-1215 kbps with the options -q 1.00...
