With latest release I still continue to have the warning "VBV parameters cannot be changed when NAL HRD is in use". What I'm doing is to use the 'zones' parameters to basically change the values of trellis and deblock. Nothing else regarding VBV values (set as BD specs). Thanks!

I can confirm that Dark Shikari's posted versions of Big Buck Bunny, Elephant's Dream, and Tallship are accepted in Adobe Encore CS4 and show as "Don't Transcode", meaning that the H.264 streams are ready for authoring to BD as-is without the need for reencoding.

However, I was unable to actually make a BD from these files because of the following:

BBB and ED: Frame rate for those two files is 24.000, Adobe Encore requires 23.976 (24/1.001) and will not allow 24.000.
Tallship: No audio available at DS's site, so I didn't try it. Although, the frame rate is within Adobe Encore's capabilities (60/1.001).


I will try encoding one of my own HD files and test it in Encore.

Could someone that already has the files check that my copies match them? My MD5 checksums are:

TallShip_lag_YUY2_5.1.avi   e95920a6eb89b0bcda723b896e77a007
TallShip_1080i_ATSC.ts       ec7e0bc1cd86c4ed59850bfc7e9dab9b

24/1 is definitely allowed so Encore needs fixing.

Oh, there is no doubt that Encore needs fixing. The list of bugs I've found in Encore could fill many pages.

Yes, 24.000 is definitely allowed on BD, but Encore refuses to make a BD using that. I believe that all assets in the project have to match the base frame rate of the project settings. e.g. If you have told Encore that the project is a BD, H.264, 1920x1080 23.976p project, then all frame rates used in the project have to be NTSC-derived (23.976p, 29.97i, 59.94i). There appears to be no option to select 24.000 or PAL-derived (25.000, 50.000) frame rates.

I did successfully download the audio for Tallship, and I made a simple BD with just the Tallship video/audio ... no menu. This was successful with no reencode of the video.

However, the audio is longer than the video by just over 8 seconds (video is 5:35, audio is 5:43) according to the original files I downloaded. This is a ~2.4 % difference, which is not accountable for by using 0.1% slowdown (for NTSC) nor 4% speedup (for PAL).

As the audio is just music, there are no audible cues that I can use to tell if the audio slowly goes out of sync over the video, or just has silence tacked on to the end.

Nevertheless, the point was to see if the H.264 video was BD-compliant enough to allow no-transcoding authoring by Encore, and it has succeeded. Well done to all the x264 developers.

BD-RE from x264 r1538+1 authored in Sony DVD-A 5.0b Build 180:

Success !

All 3 movies (BBB,ED,TS) accepted without transcoding.
"x264" Intro, Still Menu for the three movies added, no chapters.
Audio encoded to 5.1 AC-3 (resp 2.0 AC-3 for Tallship)using WavtoAC3Enc (Aften)

Muxed flawlessly in DVD-A, less than 5 minutes.
Burnt from iso to Verbatim BD-RE25 in less than 4 minutes using ImgBurn 2.5.1.0.

Panasonic BD-50 sees this as BD-Video, reports 24p for the first two movies
and throws fluid pictures and sound.

ES Duration mismatches:

Elephant's Dream:
Video duration reported as 00:10:53:19
Audio duration reported as 00:10:58:02
No video/audio offset to be noticed.

Tallship:
Video duration reported as 00:05:35:15
Audio duration reported as 00:05:43:22
No video/audio offset to be noticed,
it is a music overdub only, no original sound recording.

All 3 encodes/muxes have one navigation issue in common.
FFWD is ok. REW tries to rewind for a brief moment, then skips to movie start.

The x264 Demo Blu-ray image is available in 3 parts (7z) at http://mirror05.x264.nl/Dark/bluray.

We need just a few more things:

1. Tests to see if it works on real players.
2. A place to host the final torrent and people to seed it!

Maybe it could be added to Derf's collection at Xiph.org?
http://media.xiph.org/video/derf/

They already host a bunch of test sequences, some are up to ~5 GB in size...

[kemuri-_9]

grab the torrent from http://forum.doom9.org/showthread.php?t=154183

As i read "Announcing the first free software Blu-ray encoder" i notice that

Do keep in mind that you have to export to raw H.264 (not MKV or MP4) or else the buffering information will be slightly incorrect.

I would ask, why buffering is different if different conatiner used. In previous HRD patched this not been problem, that's mean something alredy muxed with MKV, canno't be used for BD Authoring?

Because in MKV/MP4, SPS/PPS aren't counted for buffering purposes (because they're global headers).

[Sharc]

What values have eventually been selected for the demo disk for buffer control ?

[shon3i]

vbv_maxrate=14745 / vbv_bufsize=14745

Use Piratebay.

Okay, I got the "Tallship" sequence now. Thanks! Unfortunately I see that the lossless original footage is interlaced

May I ask how that sequence was deinterlaced and resized to 720p for the x264 demo disc?

In my first attempts (using NNEDI2/NNEDI3 + Spline36Resize) some scenes looked significant worse than the x264 demo disc...

Use Piratebay.

Good joke. (You know that their tracker was forced to go offline, back in Nov 2009 ???)
