Anyways, I will look harder before posting further titles - though it seems that the 'extended' data that we get now was not listed for those titles.

Is it worth re-listing them for that extra data? I could go either way.

I have the scan for Seventh Seal done - the single line info has been posted but not the extended data...

Happy to share but don't want to add noise to the thread... thoughts?

Not sure about IE, but with Firefox you can CTRL+F for titles. You just have to keep clicking "Find Next" since S1 is below S3 and S2 as it was given a lesser audio format. I think I missed it when I was looking for the longest titles because the formatting is screwed up on it.

Info we don't have yet isn't noise to me.

Jaggies are definitely fixed. When I looked at the back of the disc I swore it was a BD25. When I saw the scan I took another look second layer ring is very faint. Not that it really matters since its only 30GB.

Still limited to 30Mbps video.. Through the first 10 mins:

Thanks Patsfan. The video bit rate on the Blu-ray is worse than the HD DVD. Another wasted opportunity.

Blu-ray : 340

Its probably about the same since our HD DVD numbers were estimates. If I had the HD DVD I could tell you more exactly.

Something looks wrong in the numbers of the Perfect Storm(comparing both the BD and HD DVD). Movie size for the BD is listed around 27 GB but having a lower video average bitrate than the HD DVD where the movie size is only 23 GB with a higher average. Something doesn't compute here. One set of the numbers has to be wrong.

The BD was scanned, the HD DVD was estimated based on file size and audio tracks. If we scanned the HD DVD I bet it would be different. Additionally the TS .m2ts files that Blu-ray uses take up alot more overhead than the PS .evo files. And the Blu-ray has many more dubs than the HD DVD. If we did a direct comparison of the video tracks it would be much more accurate.

Phantom,

Nothing is wrong with AV stats on both BD as well as the HD DVD. The Blu-ray is encoded at Warner bit rate with inclusion of multiple spoken language tracks that is missing on the HD DVD. Even if the numbers aren't accurate the error margin would be in the 1~2% range which is totally acceptable.

benes should be able to provide a definite answer.

I'm fighting in the trenches again with that tenacious enemy called peak bitrate and I have a question. Does anyone know what the video (or total mux) buffer size is supposed to be for the typical Blu-ray player?

I do know that the video bitrate is supposed to be limited to 40Mbps, video + audio at 48Mbps, and the supposed total transfer rate at 54Mbps, but many recent encodes from Sony, Disney and Fox seem to have been just slightly dialed back from the point at which your Blu-ray player might spontaneously combust. I am curious about the player buffer sizes since these might hint at a reasonable way to take peak measurements.

Though the peak A/V mux rate for Blu-ray is reported to be 48Mbps there are chances that spontaneous buffering could cause a momentary spike of up to 54Mbps. I am not sure how your BD Info scanning works but I think the easiest way to implement would be to note the bit rate every second, adding to a working list and compute the peak from the list when the scanning ends. Alternatively your program can invoke (exec) some external utility that could determine peak bit rate and include the PBR as a part of the BD Info scan report. This means you have to bundle the external utility alongside your BD Info tool. Just my $0.02.

Is there a comprehensive list of only BD titles that contain a 7.1 audio track? I just added two speakers to my system, and I'd like to test out the new setup, but there is an awful lot of great information to weed through here. Is there a filtered list available somewhere?

Thanks

Easy way to find them: CTRL+F for " 7.1" including the preceding space.

Wait a second...what's with all those extra numbers in the chapter listing? Pictures would be better...



ZOOM!



Bits and bytes... better by the kilo.



Oops! Forgot to run a certain program in the background...



Anyway, the next release of BDinfo should be interesting. Hopefully it will be ready sometime this weekend. Just a note: I have not made any changes to the current average bitrate calculation, since it seems to be working well.

Yeah, over the last day or two. I was disturbed by the peak numbers themselves when I first spit them out (I've seen 1-second peaks as high as 59Mbps) which is partially why I bailed on the effort the first time around a month or two ago, but with the charts everything seems a little more reasonable.

Most big "spec buster" peaks that I've seen are typically preceded and/or followed by a precipitous dip so don't survive into 5-to-10-second peak measurements. For example in Men in Black, many of the peaks correspond to usage of the memory eraser device. These short segments are surrounded by a white flash or black out which must give the encoder an incentive to slam the bitrate of any interim or succeeding frames of detail. A similar scenario occurs in Persepolis (an amazingly bruising bitrate extravaganza for such a seemingly simplistic looking movie) with surprisingly textured and detailed frames surrounded by very simplistic and/or mostly pure black-and-white frames.

For the chapter peak calculation, I am recording each individual frame size during the full bitrate scan and then the peaks are detected using these number when the report is generated. This is done by advancing one frame at a time and putting the frame size and length into separate first-in-first-out buffers for the 1-, 5-, and 10-second measurements. When a sufficient number of frames has been added to exceed to window size, then the peak bitrate calculation is performed and a single frame is dropped out of the queue. Thus, the numbers in the report should be accurate to the frame (the time offset of the peak is reported as the beginning of the peak period).

For the charts, the same calculations are used but in order to avoid plotting unnecessary points each per-frame bitrate calculation over the 1-, 5- or 10-second backward looking windows are aggregated into non-overlapping 1 second blocks. The min and max bitrate for each 1 second block is then used to set the lower and upper bounds of the light gray shaded area in the chart and the average bitrate within the 1 second block is shown as a dark gray line.

Thanks for the detailed explanation buddy. It not only explains the PBR calculation logic but also the efficiency (big O notation) you are trying to achieve with your utility to consume optimal share of CPU and memory during the scan.

I would like to add few words regarding the "spec buster" peaks (nice moniker btw). You can observe spec buster peaks on grainy black and white scenes (similar to a stock footage - For ex, Aviator) and on sudden transitions to a scene with heavy information.

That's ****ing hawt, Cinema Squid! Awesome stuff. I just wish I could comprehend your explanations.

Something I wanted to ask before: is the added description with "High Profile 4.1" as a result of checking Stream Diagnostics or something new?

Hey Squid - simple request.

Can we have a 'panel' for posting the summary into the forum?

The info like Java present is not included in the forum posts. It would be nice to either include it in the details panel or have a new disc summary panel.

The aim being all info posted here

That's new along with the aspect ratio (either 4:3 or 16:9 - it's not clever enough to calculate black bar sizes) and is populated after the initial disc scan. Maybe not the world's most useful information, but why not.

Good suggestion - for convenience I think I'll just repeat the disc info fields (BD-Java, copy protection) in the current playlist summary section.

Would a 4:3 movie encoded pillarboxed to 16:9 be flagged as 4:3 then?

If it was encoded to a 16:9 frame with pillars as part of the image then it would unfortunately show up as 16:9 in all likelihood. However, I would think in most cases this would be avoided because it is wasteful and the AR info should help to identify widescreen SD content, like the Rambo PiP track:
Code:
VIDEO:

Codec               Bitrate         Description     
-----               -------         -----------     
MPEG-4 AVC Video    0 kbps          1080p / 23.976fps / 16:9 / High Profile 4.1
MPEG-4 AVC Video    0 kbps          480p / 23.976fps / 16:9 / High Profile 3.2

Well actually I think it's a good thing that all files encoded to fill up 16:9 are flagged as such. It would get confusing if 16:9 could mean any "real" aspect ratio besides 4:3.

So wait, are you saying the spec actually allows for 1440x1080 4:3? I thought not, especially since all the old flicks like Casablanca that Xylon has capped so far have been pillarboxed.

I hadn't thought of SD content though, definitely useful there.
