extract AAC 5.1 audio from HD MOV

[mehargags]

Hi to all,
I just downloaded a 1080p Trailer of Ghost Rider from APPLE Trailers section. I opened the .mov into megui directly it encoded the video to x264 without a hitch. The only part left is I have not been able extract the AAC 5.1 48kHz audio from the .mov file & then transcode it to Ac3 5.1 preserving the 6 individual audio channels. searched but haven't found understandable clues/tools to do it.

I tried using river past audio converter but it gave me error unrecognizable audio(attached pic). Can u please help me out. Its just a .129 sec movie with great audio/visual effects. If incase its cumbersome to convert it to Ac3, I can live with mp3 dolby PL II @ higher bitrate..

Thx, looking for some clues here...

Using YAMB, you can extract from mov directly to new mp4 both video/audio. When you get mp4 using BeHappy or simmilar tools, you can conver it to everything you what aslo preserving real 5.1

That's not an error log.... That information tells you what has been muxed into the MP4 container.

By-the-way, you don't need the "tmcd" (track 3 -Time Code) stream... As it may cause your MP4 file to crash in other players!
