3D Bitrates

[Brandon K]

I contribute bitrates, audio specs, whether discs are single or dual layer, etc, any needed specs, whenever I see them missing (or at times, incorrect) in the database.

I'm always interested in that stuff and finding the "best" versions of movies (and lamenting bad encodes, etc), so I'm always happy to see it in the database and disappointed when I don't see it to inform my buying decisions, so I try to contribute as much as I can for others as well.

However, I'm not sure how to accurately get the bitrates for 3D discs.

I see one user Kuros has contributed them in the past, unfortunately, this user has chosen not to receive messages, so I can't send them a message to ask.

Kuros breaks it down as I should expect, measuring both the first eye AVC and the second eye MVC in order to get the total bitrate. An example:

25.641 Mbps (AVC) + 10.023 Mbps (MVC)

I've tried all the scanning tools I know of, so maybe it's just an extra process involved or something else that I'm not realizing. If anyone would reply here, or PM me on this subject, it would be appreciated! I want to get more of this data into the database.

For me personally, I always prefer a full bdinfo that has the bitrate for both streams and for the language tracks included on the disc. I can tell you that I have made many buying decisions based on such info upon comparing specs of several discs.
Here’s how I like it:

DISC INFO:

Disc Title: THE_CROODS_A_NEW_AGE
Disc Size: 38,020,052,992 bytes
Protection: AACS
Extras: BD-Java, Blu-ray 3D
BDInfo: 0.7.5.9 (compatible layout created by DVDFab 12.0.1.8)

PLAYLIST REPORT:

Name: 01113.MPLS
Length: 1:35:14.542 (h:m:s.ms)
Size: 37,094,105,088 bytes
Total Bitrate: 51.93 Mbps

VIDEO:

AUDIO:

Dolby Digital Audio Arabic 640 kbps 5.1 / 48 kHz / 640 kbps
Dolby Digital Audio English 192 kbps 2.0 / 48 kHz / 192 kbps / Dolby Surround

SUBTITLES:

Ah okay, maybe it’s a DVDFab thing. When you do a full scan does it give you the more exact bitrates? I don’t use DVDFab and the last standalone BDInfo before they took it over (unfortunately, instead of leaving it as a standalone tool) didn’t seem to give the video tracks separately, but I’ll check again. Thanks for the reply!
