DVDFab MP4 H264+Multichannel AAC

#1

Hello out there,

I have been happily using the Xvid+Audiocopy profile for creating avis with 5.1 channels. I have recently fallen in love with my iphone, which only supports mp4s with h264 and AAC.

I would like to rip my dvds once and only once - not once for my pc, and once for my iphone; however, I obviously want to keep the surround sound. AAC supports multiple channels; is it possible to configure DVD fab to convert 5.1 ac3 to 5.1 aac?

I’m not sure as I’ve not tried myself,but did you use the generec mp4.h264 .aac profile?


#3

The great difference in the video requirements for watching on a TV vs. a mobile device (size, bitrate) make it almost impossible to do a single conversion that is even a good compromise for both. DVDFab doesn’t currently support 5.1/6 channel AAC.

I realize that for most portable devices, the bitrates need to be tuned down a bit, but I can play dvd-quality H24 video on my iphone.

In addition, for apple tv users, it would be nice to have 5.1 channel aac - to the best of my knowledge, apple tv / itunes does not support ac3.

Hopefully they will add this in the future (or apple will add AC3).

Multichannel AAC and WMA is on our top to-do list, please wait.

Is there multichannel aac now included for ipod/iphone preset? Or through the profile editor? Which I’m going to go look at right now.

Apples iTunes store now has HD TV Shows downloadable from iTunes 8 that do include an AC3 5.1 track. However iTunes 8 seems to just do a passthrough rather than decode it. When selected I get no sound. I’ve seen reoprts the Apple TV does decode the AC3 track.

please forgive my technical stupididy & unfamiliarity with current gizmos , but even if you could rip 6 channel audio , how could you then possibly listen to true 6 channel surround sound audio on an iphone ???

I appreciate that iphone is a clever gizmo, but do you then carry around 6 speakers to plug into it , and/or 3 assistants to hold the speakers in the right locations ???

Obviously there is only 1 speaker and 1 microphone so you will get mono. But the iphone/ itouch have tv-out. Though the tv-out is only 2 channel with either(component/composite) cables that can be purchased from Apple. So that leaves to viewing on the apple tv, laptop, media center which would have a connection for multichannel audio.

The more I read about multichannel, the more I want it. I have been reading up about it and think it would work great thru apple tv to my home receiver. I see handbrake does it already so hopefully it comes to dvdfab soon.
