Mixing different media on a blueray, possible?

[lutinor]

I'm just asking if it's compliant to mix different media like :

25fps media 1 on the menu
23.xx media 2 etc...
Different resolution ?

I'm not talking about a java pop up menu but it's about a hdmv menu standart...

I'm not sure cause on commercial movie, everything is the same on the disc...

Opinion ? :confused:

Yep, you can mix everything you want, it just has to be in a different Playlist/title.

A lot of commercial titles have SD content, sometimes even Mpeg2 right off the DVD release, along with the HD feature.

We just finished a disc that one bonus piece has an SD intro and HD main piece. Two different Playlists, programmed it to jump from one to the next...

The annoying thing about it is you have to create menus to match the size of the video if you want a pop-up menu on the video (regardless of HDMV or Java programming). If you don't care about a pop-up, then it's no big deal.

Different video sizes, frame-rates, codecs, different audio codecs, blu-ray doesn't care, it'll switch around between all of them.

The only thing to be careful of is PAL video. You can put it on the disc, but some players in the US/Japan (NTSC land) will refuse to play PAL, and when they hit it, the disc stops playing (the PS3 is one of these). So if you have a trailer that plays at the beginning, and it's PAL, an NTSC player may never get to the menus. If you are in Europe, and don't care about the rest of the world, go for it. :) (This is a problem I've run into importing discs from the UK... Had to hack the disc and remove the PAL header stuff just so I could watch the film on my PS3...)

Good tips, thx :thanks:

The only thing to be careful of is PAL video. I see also this on other place, but i don't get it why PAL wont be playable on NTSC, for example 1080@50hz not work but 1080@60hz will work

There's no reason why players in the US won't play PAL, they are simply programmed not to (speaking specifically of the PS3). The hardware in the PS3 is the same in the US and UK, it's just the software. It's not that it _can't_ play it, it just won't play it... Really damn annoying. Granted, if it output a true PAL signal, and your TV can't handle it, it'll be unwatchable... That might be why it blocks it. It'd be nice if it just skipped though, rather than stopping the disc. I think it assumes it's from the wrong region.

The PS3 Test will allow you to switch from PAL to NTSC modes, so I know it's just the software saying 'don't do it'. Not sure, but I bet in the UK the PS3 can play all NTSC video...

there is two spec for blu ray video:

the base with 23.976, 24, 29.97, 59.94
and the optional that add 25, 50

in the us they choose to use base only !!!

Hi rik1138 (This is a problem I've run into importing discs from the UK... Had to hack the disc and remove the PAL header stuff just so I could watch the film on my PS3...), how you do it??? with which soft???
I used tsMuxer, BDedit, CLIPINF_Edit and will not start sony player.
I need your help thanks..

Well, it depends on the title... The title I was working with (City of Ember) was HDMV programmed, so I didn't have to worry about Java... If I remember correctly, it had an HD logo, then two SD PAL trailers, and then it went to the menu. I used BDedit and copied the end command of the last trailer to the end of the HD logo, so it plays the logo, then skips the trailers and goes to the main menu. In this case, it was easy... The disc will still crash (in the PS3) if I try to play any of the PAL bonus content, but at least I can watch the movie. The trick is keeping the player from over touching the PAL clips. Even if you put a 'pre command' on the title with the PAL video telling it to jump somewhere, I think the player will still stop once it realizes it's getting close to a PAL asset...

The other way I can think of is to locate all the PAL streams/Playlists and just replace them with a small piece of NTSC black (or, if you are really determined, re-encode them from PAL to NTSC and put them back on the disc...). That would fix the problem regardless of how the disc is programmed...

I'm sure others here have run into this problem, they might have different ideas...

Also, if you just care about the movie, you can use TSMuxer and just re-mux the film itself to another disc (no menus or anything) and create a playable disc.
