MKV to MP4 conversion software for WIN7/8? (without loss in audioquality)

[alexeliasson]

Hi!

English is not my native language, which contributes to that I sometimes prefer having subtitles on the movies that I watch(with my iPad and ATV3).

I discovered the software "wondershare video converter" wich can encode different video filetypes to mp4, and also add subtitles. However, when I do this I get a substantial loss in audioquality. Doesn't mather if I peak every option in the settings tab, there's still a GREAT loss.

Any ideas for other encoding software? Needs to do these things: avi/mkv to mp4, hardcode .srt and no substantial loss in video or audioquality.

I've tried the mkvtomp4, but there are so many settings to pick in the audio-category. Any small help here? Also, there's my 'belief' that wondershare keeps the videoquality more untouched. I'm I wrong here? All help appreciated guys.

mkvtomp4 doesn't reconvert the video. If it's not required(non h264 video).

What is the audio in the mkv? Use mediainfo to identify.

Guess I was way out wrong on that one! Thanks

The audio, according to mediainfo, is the following: 445kbps, 48.0khz, 6 channels AAC.

If I want to keep the audio AS IS - is the mkvtomp4 the software to use? Also, which settings do I then use in it?
