is there a difference with retail Blu-Ray discs wordwide ?

hi RB members , is there any difference from retail Australian Blu-Ray discs to American Blu-Ray discs ?


For example Framerate like retail DVD discs .........


If im correct with Blu-Ray the Framerate is the same across both regions but there is a Region lock so you need a Multizone Blu-Ray Player.

Different regions tend to have different retail releases, which can change what packaging/special features/etc there are.

There are regions, and players are supposed to abide by them, however, it's up to the individual studios as to whether or not they use it. Wikipedia claims around 70% of releases are actually region free.

The Blu-ray spec allows for a variety of video formats, but the most common that you'd see will be 1080p, 24fps, regardless of the region.
That said, there are other formats that crop up, particularly if you're looking at (say) British TV releases. Those may be in a 50hz format, and not all gear sold in the U.S. handles that correctly, (where gear sold in R2 should handle 60hz content just fine due to it being the current/future spec for everyone).

Whether or not you'd need a multizone player would depend on exactly what it is you want to import. Or, of course, if you want to play import DVDs on the player as well.

The cool think about BD is, there are only three regions, so its much more simplified. Even within regions releases can be different. A good example is the Canadian Versions of Scream and Halloween. Even though its both Region A, Canada got the Scream Trilogy on BD long before the US, and they got it in a 3 disc pack before the US. The last three Halloweens before the remake got released first in Canada. Two of there were finally released here, but they fucked up and didn't put them in Original Aspect Ratio here, even though the Canadian releases were correct.

I don't think that is true for bluray. It is simply either 24, 30 or 60fps. Won't make a blind jot of difference. Anything using the HDMI standard is interoperable with all systems displaying the HDMI logo world wide. We don't have a different video standard. It's all universal now.

All Blurays are 24FPS, the freq is fine these days and universal, only region locking is the difference.
Blu-rays should be watched at 1080P@24 or 1080P@120, anything else is not as smooth!

Interesting fact, 24fps would still be flickery to us, so pull down occurs at 2:2 or 5:5 depending on the TV/Projector etc. Meaning that for 24fps, 48 frames are actually displayed. Cool huh?

And 2 are repeated, making the image not as smooth?

No it makes it smoother because we interpolate the images and ignore the duplicates.

The Blu-ray spec does allow for more than just that. Content may not be created in other formats much anymore, but older content that was, on occasion, seem to make it to disc without being changed.

In turn, there are issues with 50hz content on U.S. (at least) equipment. Enough that there are compatibility lists.

This has been a topic on AVSforum and the like multiple times. (this thread for example, and an earlier thread was linked in the first few posts).

We don't so much ignore the duplicates in that case. All they're doing is showing every frame equally, as compared to 3:2 pulldown or the like. Smoothness issues related to showing some frames more than others are addressed, issues due to 24fps just not really being that smooth are not.

Thing is, we're used to the jerkiness of 24fps due to films being shot at that since they started including an audio track. Things that truly are smoother can come across as odd - or at least, not looking like a movie to us. IE, motion interpolation features making feature films look like soap operas.
