Handbrake SVN now has AC3 in the MP4 container

Diode · 11:47 AM

Handbrake has the AC3 patch for a MP4 container in their svn

http://trac.handbrake.fr/changeset/1261

I'm not at home so I can't test how well it works but reports are saying so far so good.

For those willing just compile from source ... otherwise wait for the release ... no idea how long it will take.

Sorry for my ignorance but is this something in an update or how do I utilize this info? I use HB a lot and want to take advantage.

does this mean VH will be getting a mp4 container soon too?

For now you need to compile the code from the SVN in order to gain the feature. Anyone can do this but it takes some technical know-how to perform.

I'm sure they will release a update soon when they think the update is stable enough for general use.

It's implemented into the gui by selecting the 3rd mp4 option ATC/H.264 / AC-3

No idea .. I would assume they are not far behind. Don't use that product so I don't follow it's development.

alFR · Feb 14, 2008, 12:04 PM

Kevin,

To use this you would have to download the source code from the developer's subversion repository and compile it yourself. If you don't already know how to do that (I don't!) then you're better waiting for the full release.

NightStorm · Feb 14, 2008, 12:04 PM

If you do compile your own, please do not expect to receive any support for this feature... they strongly discourage users reporting problems with SVN code on their forums; it is really there so that other developers can help.

OldSkoolNJ · Feb 14, 2008, 12:07 PM

Right! .... *waiting*

You sir are correct. I posted this merely to show that a solution has been found and is in the pipeline for a future release.

Great news. Sounds like I have to recode all my dvds or do you anticipate there will be an easy way to convert just the audio?

The handbrake developers themselves are planning on re-encoding after this release. There is also going to be better iPod encoding with anamorphic support as well.

visual hub was updated earlier on today- with support for take two.

Only on .mov files though right? I need .mp4 to hold the meta tags...

Krevnik · Feb 14, 2008, 04:37 PM

What sucks is that it seems that it still only works on the ATV, because it will only have the AC3 track, and not a mix of AC3 and a AAC stereo.

to be honest mate with my g5 it's gonna take me a while to find out! Started my first encode last night, and it currently says...

Looks like I lied, file 1 will be done when it's done.

I love VH

DD 5.1 work on VH, but your right its a .mov file. You do lose MetaX tagging, as well as chapters and subtitles for foreign films.

I wouldn't be surprised to see that 0.9.2 will have both AC3 and AAC 2-channel embedded in the transcode. Patience...

Oh, I know they are working towards it... but right now Handbrake's design doesn't understand how to handle encoding different audio streams into different codecs (or passing them through in this case).

Depending on what they want to do for 0.9.2, they might not have time for such work.

Nor would I.

jaw04005 · Feb 14, 2008, 07:44 PM

So as an experiment, I encoded a few chapters of a Ratatouille as both an MPEG-4 with AAC and MKV with AC3.

Then I extracted the AC3 sound file out of the MKV file, pasted it into the MPEG-4 file and voilà.

Seems to work fine on both my Apple TV and through QuickTime (with Perian 1.1 installed). I was quite surprised that the audio and video actually synced up.

Anyways, I think I'll wait for Handbrake to get updated before I do any full re-encodes.

cohibadad · Feb 14, 2008, 08:34 PM

yeah I tried an old AC3 experiment file with the new

TV and it played in 5.1 fine. Will need to have Perian on any mac that I want to be able to listen to the new encodes but that's no big deal. Looks like I will have dual encodes for each movie:

TV5.1 and iPhone/iPod.

That is exactly what they are working on.

How are you accomplishing this? I'm trying to put the AC3 audio from an .MKV into a .MP4. I've tried doing it in QuickTime but it just puts the two files end to end (video plays and then the audio plays).

Cave Man · Feb 15, 2008, 03:00 PM

Make sure your scrubber is all the way to the left (start point) before you add to movie.
