Multi-audio and subtitles in iTunes 7.6 / Quicktime

[RadicalxEdward]

Greetings doom9 forums goers,

This is my first post here so bare with me please. I've found this forum extremely useful in the past and this is the first time i've ever needed to register to ask a question.

So as to the topic at hand. At this past Macworld Expo at Moscone West in SF Steve Jobs announced iTunes would support multiple audio tracks as well as subtitles. I've been hoping for this for a very long time. Finally i can convert my video library (with dual audio tracks) to mp4 and not worry about losing anything.

I muxed together some mp4 in a variety of ways (including using AutoMKV which is awesome by the way, i love being able to fine tune things. as well as mp4box and YAMB) and it works great going from mkv to mp4.

When i mux with yamb (not needing any converting):
I open them up in VLC and everything looks great. Dual audio works, as well as subtitles. Then i open it in quicktime (or iTunes 7.6) and it's a mess. The video plays fine, but there are no subtitles. The subtitles menu only has one option "default" and it's checked off. The audio is a mess too, both audio tracks play at the SAME time. Japanese and english. The language and audio menu again only has one option, "default" which is again checked off.

muxing/converting with automkv when conversion is needed:
When i convert with AutoMKV to h.264 mp4, despite it being better overall (works exactly the way i want at the file size and quality i want) it won't play right either. it has the same problems as the other method, but the video skips around (shows a few frames, stalls, time passes, audio plays, a few more frames, etc)

Lastly, when i convert anything of that with SUPER:
The video quality goes down noticeably despite file size going up a little and i'm stuck with no subs and a single audio track. BUT it does play fine in iTunes and quicktime.

SO my question to you all is if you guys know how to get this working in quicktime/iTunes, or have any documentation. Or if you know if this only works for stuff bought on the iTunes store.

I did search the forum, but didn't find anything helpful. But if you know of another post with relevant information feel free to direct me. Also, i wasn't exactly sure where to post this, so if you feel it should have been posted elsewhere feel free to let me know.

I'm not a real n00b. So you can be technical, but i don't know a whole lot about h.264 profiles and things too too technical (other than iTunes supports 3 and 2.1 i think, but i can't find where to choose that in AutoMKV) I welcome any questions about settings of either AutoMKV, YAMB, SUPER, or the video files.

Thank you all for your help,

I also wanted to say what a great job AutoMKV does, it gives me great quality at perfect file sizes. Only problem, when i play the files in quicktime, qt chokes. Anyone else have this problem?

QT on windows is just lame like that - Apple feels no incentive to make it work well on a PC. Use another player is the only choice.

Hey,

I had the same problem as you did. I encoded a movie with MeGUI and the muxed it with Yamb. Wotked fine in VLC, but the nice little language track button did not show up in iTunes.

Here is the thing. You can use the Yamb method to mux you movies. But to tell iTunes and QT that the movie has more than one track you will need to write it into the movie atoms of the mp4 file.

You can do this with a small program called Dumpster. I'm using it under MacOS but I know there is a version for Windows too. If you like I can give you a short guide, but only if you use MacOS.
I've never done it with Windows.

Cheers

Hi!

Have you tried using Quicktime Professional to make your conversions?
