I've waisted quite a few hours on this myself. Furthest I got was to compile mp4v2, and succesfully add the hd tag to a file. However this currently appears to corrupt pretty much all of the other meta-data in the file, making it unreadable and untaggable with meta-x. I've also messed around with hex-editors etc., but nothing useful has come out of that on this end.
I just tag my full dvd res files also as hd, while tht doesn't help with separating sd from hd content at least I can combine the entries for the AppleTV and the iPod version
So are you saying that you have successfully combined your own content into a single file listing? If so how did you accomplish this?
Gotcha, keep up the good work! I'll keep watching this and the other various forums around for developments.I'm one of the mp4v2 devs and it was me who added the support for the HD Tag and a lot more metadata improvements.
Together with NightStorm and refulgentis I was also able to add the functionality needed to combine HD and SD encodes, however there's currently no stable release of mp4v2 nor binaries that are available to the public (I posted some here after the HD Tag was added, afaik those are the last binaries available).
Anyone have a chance to see how the new HDSD movies from the itunes store are "put together". Seeing as we have to "trick" itunes right now by changing the type temporarily to a tv show before it will combine user encoded movies. From what I've read it seems the HD movie downloads from the itunes store are both a HD and SD version combined, but iTunes won't currently combine user files with their type set to movie. So how is apple doing it for movies?
Set stik == 9 (or movie kind == Short Movie). This is how iTunes is doing it now. If you notice, in 8.1 they have removed the "Short Movie" option from the media type drop down box. As long as you've followed the other steps (identical cnID, HD encode with hdvd atom == 1), it will show combined in Movies without the "trick".
Thanks to refulgentis for purchasing a movie from the iTunes Store tonight and reporting this finding in the mp4v2 IRC channel.
Is anyone aware of how to perform this in Windows? Or better yet, has a Windows GUI been created? Any help would be greatly appreciated!
