Just check one. Otherwise if you attempt to play the file on your Apple TV it will get confused and not know which one to pick.In subler if I have multiple audio tracks added (dts, ac3, and ac3 > aac dolby pro logic II) Do I have to check enabled on all of them before encoding?
this is how the file should look once finishedWhich of the three should I enable? And will the atv know which track to use automatically even if only one specific one is enabled? Right now I am using the atv hooked up to just the tv but soon plan on using optical out to a receiver so that I can get real 5.1 dts or ac3 output.
My MP4 files have the first track (AAC Stereo) enabled and the second (AC-3 5.1) disabled. My ATV 2 is connected to a receiver and it switches to the surround sound track automatically.Which of the three should I enable? And will the atv know which track to use automatically even if only one specific one is enabled? Right now I am using the atv hooked up to just the tv but soon plan on using optical out to a receiver so that I can get real 5.1 dts or ac3 output.
I know it's not necessary, but I wonder if it's still a good idea. The Subler FAQ has the following about alternate groups:no need for that
Given the Apple TVs reliance on iTunes and properly configured MP4s, the suggestions from the Subler developer might be worth following.Adding multiple soundtracks
QuickTime has the ability, like a DVD, to include multiple soundtracks and let you select the one you want for playback. Subler is an easy way to add these to your existing movies.
To add a new soundtrack to a movie, follow the steps above to create a project and open the file, then...
5) Select Import->File... from the File menu or click the + button above the track listing in the project window.
6) Use the Open dialog to find the sound file and Open it.
7) Repeat (5) and (6) for each additional soundtrack you want to add.
8) Click on the first track you added, so that the Sound Settings pane appears at the bottom of the document.
9) In the upper pane, select the correct language for the track.
10) In the bottom pane, Select the same "Alternate Group" for each one, typically 1.
11) Repeat (8) through (10) for each of the tracks you imported.
Hint: The first Sound Track in the track list in the upper pane will define the "default" one when opened in QuickTime Player.
Another hint: If you're also adding multiple subtitle tracks, assign them to a different Alternate Group, say 2.
