My guess on I am Legend was correct. It's 16 Mbps AVBR. Shame on you Warner was tactically fooling us with seamless branching BS.

Blu-ray : 340

I was finally able to make some progress this weekend on the "BDInfo" video and audio specification collection tool that I mentioned about a month ago. It seems to be working fairly well, so I've put up a download link if anyone is interested in trying it out.

The bitrate estimation appears to be fairly accurate - within about +/- 10 kbps (0.01 Mbps) of the currently listed titles in this thread. However, there are a couple of known problems with the tool:

* First, performance can be absolutely dreadful when scanning a physical disc in a BD-ROM drive. For that reason, I recommend only scanning mounted .ISO images or hard drive folders for the time being.

* Also, the detection of the bit-depth of Dolby TrueHD audio tracks and the detection of bit-depth, sample rate and channel layout of DTS-HD is not currently working properly. For Dolby TrueHD, the bit-depth of the samples (i.e. 16-, 20-, 24-bit) is not reported in the audio headers. At the moment, I am making a guess based on other parameters, but it is not always correct. For DTS-HD (both high-res and master audio), the layout of these headers remains an undocumented mystery and I've pretty much given up on trying to figure them out myself. Hopefully someone else will figure this out, but in the meantime I am taking the approach of eac3to and simply copying over these values from the core DTS stream.

Part of the output of the BDInfo tool is a snippet of vBulletin code that can be pasted into these forums. It roughly matches the current format used here, but may not be 100% correct. Any suggestions on tweaking that output to make life easier are welcome.

Hopefully this tool takes some of the arcane twiddling out of collecting this information and encourages more participation and submissions to this thread. (On that note, I've basically only run full scans on titles that have already been submitted here so I could check the accuracy of the results, but I'll start submitting more title info myself.)

Excellent work Cinema Squid.

Is there some kind of API available to query / manipulate Blu-ray ?

What programming language you used to implement this tool (VC++, VB.Net) ?

I think Studios should include a stat box feature on Blu-rays that will provide technical information about the disc. It can be hard-coded on the Blu-ray as per the information derived using their own measurement tools. This will prevent programmers to come-up with tools that needs to be perform full scan of the disc to produce the technical information.

I have a question ? Does your tool eat up the CPU throughout the scan time ? How is the performance on machines equipped with dual core processors ?

Blu-ray : 340

Amazing tool Cinema Squid, thank you! This should make gathering disc info much much easier.

Scanning the main movie playlist for Ice Age in a hard drive folder took 23 minutes on my Athlon64 X2 4600+, not bad IMO. It appears to use multiple threads but not completely optimized, around 50%+15% usage.

Not any that I am aware of. There are, however, a few open source projects that have bits and pieces of the necessary code including xport, ffmpeg and TsRemux.

I used C#.NET and Visual Studio 2008 (targeting .NET Framework 2.0). However, I am primarily a Mac user, so once Apple gets off their butts with Blu-ray support, I will likely port the relevant bits into C or C++.

That would be nice, although just like the specs on the back of the Blu-ray cases, part of the problem is how much you can trust their accuracy! Fox places the AVC video bitrates on their cases and these are listed as "advertised bitrate" in the OP, but as you can see they are not always on the money.

It does chew up a perhaps inordinate amount of CPU on a single-processor system, however, I'm assuming that dual core or higher machines should be nearly ubiquitous for Blu-ray equipped HTPCs. If this assumption is not valid, then perhaps I should make the tool more friendly to single-processor systems. There is currently no significant performance gain from leveraging multiple processors because the bitrate analysis is largely I/O bound and I have only a single disc reader thread which presents the main performance bottleneck. Theoretically, I could scan multiple sections of a disc simultaneously, but I am thinking this would actually be detrimental to performance - especially while scanning an optical disc.

Maybe off-topic for audio and video specifications, but is there any way for software to check the region coding of Blu-rays?

This is definitely possible, although it does not seem as easy to detect as it was on DVD. As far as I can tell, this information is stored in MovieObject.bdmv as described by the author of BD Structure Edit.

Thank you for the excellent contributions Cinema Squid.

I really like to see these specs breakdown of Blu-ray discs.

^^ Not sure if that is strictly necessary or desirable, but if benes would prefer us to edit these directly into the OP then I am willing to do that.

One note first: of the titles I've listed thus far, only Enchanted consists of multiple M2TS files as indicated by (#) in the OP. All other titles have been either a single M2TS or a single M2TS combined with a short (~1 second) "garbage" M2TS. I will indicate this with the proper symbol going forward.

Anyway, getting towards the last of my collection that is not already in the OP:

*NOTE: Hellboy seems to be the same as the already listed EU version, although I have listed it again since my measured disc and video sizes are slightly different from the EU listing.

**NOTE: The Life of Brian secondary TrueHD track appears to be a 24-bit upconvert of the 16-bit LPCM track.

This is turning out to be amongst the most useful thread in this forum. Kudos to benes and other recent contributors.

For example, it doesn't take more than 15 minutes to find out the remaining space left especially in the FOX titles that contain zero extras.

Regarding the Dogma entry above - the bitrate of the TrueHD track implies that this is a 24-bit track, especially since it is higher than the 4608kbps of an equivalent uncompressed LPCM track! I see that High-Def Digest also reported this as a 16-bit track, but this doesn't look quite right.

I had put some estimation for this in BDInfo, since the bit depth is not reported by the TrueHD headers, but apparently it is pretty much completely broken in the current version and will always report 16-bit.

For TrueHD tracks, I have been running the M2TS files through the eac3to tool to convert the TrueHD to LPCM in order to determine the bit depth. It is my understanding (and madshi can correct me if I'm wrong) that eac3to basically tracks the individual decoded sample values in the audio stream. If all of the sample values are small enough to fit into 16-bit integers then the track is declared 16-bit. If larger values are found, then the track is declared 24-bit (not sure if it tries to fit into 20-bit).

This approach would be painful for me to integrate into BDInfo since I do not actually decode any of the video or audio streams currently - just examine their headers and count packet data sizes. However, from the TrueHD tracks I have examined thus far, it seems that calculating the average compressed bit depth and using thresholds to determine 16- vs. 24-bit might be reasonably accurate.

For example, Dogma's 5962kbps bitrate gives an average compressed bit depth of 5962kbps / 48kHz / 6chan = 20.7-bit which is toward the high end of TrueHD 24-bit rates with a compression ratio of 1.16:1 (13.75%). Enchanted's is the lowest TrueHD 24-bit rate that I have seen thus far at 3879kbps = ~13.5-bit or a compression ratio of 1.78:1 (43.75%).

I was thinking of setting the compression ratio threshold at 2:1 (50%), so basically any TrueHD track with a bitrate > 3456kbps would be marked as 24-bit and < 3456kbps would be marked as 16-bit. This would not handle the 20-bit case, however.

Alternatively, I could change BDInfo to just leave the bit-depth blank until a better solution is found.

That's sounds like an excellent idea which I always had in mind but failing to post fearing backlash.

I think the logic you suggested would be good because not many titles are encoded with a bit depth of 20-bit.

I've just tried eac3to. It says "this audio track contains more than 16 bits of information" and then creates a ".24bit.pcm" file. Kind of strange that it says "more than 16" rather than just saying 24.. I wonder if it creates 24-bit for 20-bit as well? benes, how were the 20-bit tracks currently listed determined?

Thank you benes for maintaining this excellent thread!

I've got some more titles below. I'm a little sad, however, since I rented The Golden Compass from Netflix and was curious about its specs since it has a relatively rare 7.1 audio mix and also has some conflicting opinions on its video quality. Unfortunately, I somehow analyzed Michael Clayton twice instead and already sent The Golden Compass back in the mail before I realized my mistake. Oh well...

NOTE: For each disc of Damages, each episode was represented by a separate M2TS file. I summed the episode lengths and sizes to give an overall length and size for the disc. Similarly, the total/video/audio bitrates were averaged across the episodes on each disc. In theory, these could be listed separately by episode, but that would be a little bit more work since I'd have to figure out which episode was which!

Wow at Damages, 3:36:19 of "main movie" content on one disc. The next highest I see listed is Troy DC at 3:16:02... and that disc was only 29.8GB?!

benes, I see you changed "(UK)" to "(EU)" for TFTM. I assumed UK was the right tag since I don't think it's out in another country and Pan's Labyrinth also has that. Or is PL only listed that way to differentiate from the German disc?

Paidgeek also mentioned a few other Sony titles as being 20bit including Stomp the Yard I believe.

Benes,

There are some titles that feature 6.1 ch audio with 16-bit depth (Dolby True HD EX). Expect the bit rates of these encodes to be on par with 5.1 ch audio with 20-bit depth.

Also are you sure about the audio bitrate on Transformers? DTS is normally 1509Kbps. The disc is also supposed to have a 2.0 AC3 track as well.

These are both my fault to a certain extent. First, when I construct the forum post line in BDInfo, I disregard Dolby Digital 2.0 tracks from consideration for secondary audio tracks since most commentary tracks use this. Some care still needs to be taken when considering which audio tracks are relevant and whether the BDInfo output has selected the correct primary and secondary audio tracks, especially for movies where the native language track is not English.

Regarding DTS 754/1509 kbps vs. 768/1536 kbps: this was discussed recently in the Audio Codec Heirarchy thread without, IMHO, a satisfying conclusion. I will say that FFMPEG's DTS bitrate lookup table has entries for 768000 and 1536000 bits per second, but not 754000 and 1509000 bits per second . Doing a site search on site:dtsonline.com it seems both variants of the bitrate label are used rather freely.

Personally, I find 768/1536 much more satisfying since the first is exactly half the other and both numbers are evenly divisible by 16/24 (for bit depth) as well as 2/3/4/6 (for channel counts) and 48/96 (for sample rates) . Conversely, the relationship between 754/1509 is clearly hiding some rounding errors and, in conclusion, those two numbers just plain suck and 768/1536 are awesome!

benes, it has 5.1 DTS, 5.1 AC3, and 2.0 AC3. Are you saying 2.0 should be listed as secondary (and how would you decide this?) or do you want to add a tertiary audio track field?
