Just a quick update: I uploaded BDInfo v.0.2.2 which has two minor tweaks to (again) fix some problems with MPLS playlist reading and to resolve the problem with correctly identifying 6.1 TrueHD tracks (e.g. Shinobi). Not a critical update, but recommended if you are using the tool.

This just occurred to me looking at National Treasure 2 in BDInfo... I just posted about how there is a language selection menu if you play it in Region B. Five language tracks, five "duplicate" main movie playlists = identical playlist but with different default language track/subtitles set?

I selected French from the startup menu then played the movie and it plays a 3-second video with the French-translated title before launching into the main playlist with French DD640 and player-generated subtitles for translations of onscreen text.

But when I went to Malay it still had English menus. The movie played back with English TrueHD and Malay subs, since there is no Malay audio track. The 5 playlists can't be for setting up these subs since there are 9 languages and English SDH. So perhaps default subs aren't set with playlists, or perhaps my theory is just plain wrong.

BTW, the 480p stream muxed into the main movie appears as "DTS-HD Audio" in v0.2.2.

Yes, it says that for NT2 and Untraceable. However when you have eac3to scan the playlist it says this seems to not be a valid track and disappears. That seems to be a phantom track because the secondary audio is usually a DD 2.0 track.

You guys have done a great job.

When I get a moment I hope to get BDInfo set up and then will try to get some submissions together myself.

Cheers!

I hope that it's on BD-50 and features a high bit rate transfer and let's hope that there aren't any last minute surprises.

24 Mbps AVBR on Dirty Harry seems to be a respectable number for a Warner title.

No doubt that is a BD optimized encode since their total ABR is over 30. Things are looking up for Warner.
post #250 of 1971
6/5/08 at 10:21pm
Good point. Only if the VBR goes above 32+ Mbps we can be assured that WB have done a BD optimized encode. I think dvdbeaver confirmed the bits on DH hovered between 30~40 Mbps.

That's fine by me - I'll end up scanning it anyway for my own purposes, but I don't need to have the "scoop" so to speak. Oh yeah and since I've never seen it, I'll actually be watching it at some point over the weekend as well.

Zodiac Blu-ray (Warner)

zonadvd reports 15,73 Mbps as the video bit rate which is 3.03 Mbps lower than the HD DVD AVBR.

Are you ripping to your hard drive then scanning? It will go many times faster if you do.

Cinema Squid- Is there a way that you can have BDInfo give you the peak bitrates for each track? I think this will help determine if 5.1 tracks are 24/16 bits. Also we can see if Warner is finally doing BD specific encodes.

I think this should be doable. I'll experiment around with calculating peak bitrates this weekend to see if I can get reasonably accurate numbers.

I guess we need to define what peak means... ie, bitrate over what period.

For video perhaps a GOP is a reasonable period - or maybe too long a period?

Anyone else have any thoughts on what time frame a peak should be measured over?

Thanks a lot Phloyd for posting the stats for Shooter. I am indeed a tad disappointed but 28.36 Mbps is well above the AVBRs of Black Hawk Down, Flyboys and Kingdom of Heaven.

I found out something strange. The BD extras seem to have occupied about 8 GB in comparison to the 6 GB consumed by HD DVD. Was even the extras presented in higher bit rate ?

I assumed it would naturally be for a second since we're measuring in Mbps?

DGIndex (MPEG-2) and DGAVCIndex (AVC) give min/max/avg bitrates. I do seem to recall their max being lower than peaks I saw with the PS3 meter so perhaps they are using a different period of time.
post #264 of 1971
6/6/08 at 6:39pm
I wouldn't call the bit rate meter on the PS3 totally inaccurate as I did a comparison with the bit rates displayed by some BD recorders out here and all of them displayed similar bit rates. However there may be some amount of inaccuracy which I think would be in a very small range.
post #265 of 1971
6/6/08 at 9:18pm
The PS3's video bitrate meter constantly and evenly overshoots a disc's actual video rate. I've seen video peaks for brief stretches on the PS3 hit 48 Mbps which should be impossible on Blu-ray. I think people will be in the right ballpark if they subtract 2 to 3 Mbps for the average seen from a PS3 and possibly more on peaks.

It's been discussed before that it's actually not impossible.

Interesting.. The time stamp on the main video file is dated 3/19/2008 but there are files with timestamps of 2/29/08... Most of the files are dated 4/2/2008 so thats when it must have been authored. When did Toshiba announce the folding of HD DVD? Found it (2/19/2008) It seems like they started working on this around the that time, or maybe even earlier.

It's nice of Paramount to max out "There Will Be Blood" on a BD-50. I really hope they do this for all their future releases.
