LOL I know, I'm sorry, it's one of my con's. I don't have much time these days so when I do post question I tend to get it all out at once. Unfortunately, this tends to result in "tl;dr"
Oooops,
my bad!
This makes sense. I had DVD(1), DVD(2) and HD(720P) selected. I wrongly (and dumbly) assumed these options were similar to the audio layers in that selecting more than one layer (embedding multiple audio tracks in one m4v) would allow the video to be played on various devices.
In each profile what is the best video option? Example, DVD(1): "High Profile", "Apple TV 2" or "Universal". What is the quality for each profile and what is the best option to maintain video quality for playback on various m4v capable devices? I assumed "High Profile" was better than "Apple TV 2", but then "Universal" is thrown into the equation.
Perfect sense now, thank you. If I want a different encoding process I must use the "Custom" selection and the related command line for my particular needs as each profile is already customized for that particular device (ex Apple TV, iPad, etc.)
On this I researched a lot. I realize a higher quality Bitrate of around 2000 with 2-pass encoding is more than necessary for the Apple TV 2. However at the recommendations of many I decided on this as to maintain the closest in video quality to the source DVD as possible and to (hopefully) future proof the movie rip. As well, playing the movie through XBMC allows the Apple TV 2 to use about every codec available and can force an output of 1080P, thereby bypassing the aTV's iOS downscaling of high def to 720P
Lord I'm such a blond sometimes. For some reason I bought AAC outputted in 2-channel (think I read that in another forums). There are so many I thought it was necessary to choose more than one for universal device capability. I'm guessing only one track is needed and the device itself (such as an iPad) will handle the audio by decoding it. If this is the case, what is the best audio (AC3 being constant):
AAC (Core Audio)
AC3 Passthru
AC3
Then with those choices what is the best:
Dolby Surround
Dolby Pro Logic II
6-channel discrete
Bitrate
I assumed AC3 with 6-channel discrete at 640 kbps was the best quality audio layer. Now I'm realizing that
AC3 (5.1) w/ AAC (CoreAudio) and 6-channel discrete may be the best (and only necessary) audio layer.
You are the best! Thank you so much, I know I have been a complete PITA, and I can't imagine having to deal with my endless questions lol. I just want to do this once and do it right. Oddly I'm not a noob but I've become very humble in this learning process. THANK YOU!
