and eventually apply audio pitch correction for the sensitive listener.
I forgot to said that, yes, music can be the exception, when you perfectly know a music/song, you can notice the speedup even in absolute.

The few times i've tried pitch correction, the result was... "howfull", and you'll harm even more a sensitive listener.
But, it was a little time ago (several years), so maybe now it's better... :?:

Otherwise, i've personnaly authored 25p (576 and 1080) Blu-Ray tricking with "fake interlaced" when encoding, and it played on my standalone player perfectly.
After, i didn't try on others players, so...

Finally (!) I found the document which made me believe that not all Blu-Ray players support 25 fps ("PAL"), and converting 25 to 29.97 ("NTSC") might still be advisable to be on the safe side, even in the global Blu-Ray age.

Search for example for "50Hz" in the document here (e.g. Para. 3.3.1, 3.3.2, 6.2.1):

What about if you omit menus? BDMV has many arbitrary restrictions that don't apply to stand alone video files, e.g. the low consecutive B-frame cap.

I've read indeed the document, it's... astonashing.
I mean, it's supposed to be a spec. Either a video format is supported, or it's not.
How can you have a spec with a format "wich may not be supported by all players"...?
It's totaly useless.

No. It is NOT a spec. As the title says, it is just a White Paper (a tutorial if you like). That makes a huge difference.
I don't have access to the Blu-Ray spec. but I think to remember that it is a document of more than 1000 pages.
