We're preparing everything to author our demo x264 Blu-ray. Here's what we have so far: three encoded video streams and three 5.1 audio streams (to be encoded however one wants).

Things we'd Like To Have:

1. A menu to pick between the three video clips.

2. A short intro sequence (I can make it, it'd just have to be integrated into the Blu-ray accordingly).

3. Some sort of background image or video loop for the main menu (Again, I can make the actual image/video).

Is there anyone here who has enough experience to do the Blu-ray authoring side of things for these tasks?

[Emulgator]

I can offer test compiles on:
Sony DVD-A 5.0b Build 180
Adobe Encore CS3 Build 3.0.1.008
Sonic/Roxio DVDitProHD 6.4 Build 641B03A
Ulead DVD-MF 6+ Build 6.00.0194.0 (not sure about transcoding preferences though)
(Pegasys TAW 4 Build 4.0.9.37 does not mux H.264 without transcoding anyway)

I will ask my colleague if he can put it together in Scenarist.
Can use some stock footage as a background.
Can encode audio to DTS-MA.

I'll do all the art and stuff; don't need to do any of that.

Also, as you may be able to tell, I made a small screwup on the tallship encode, so re-doing that

Haven't seen it yet.
Is there a banding in this encodes (sources)?

The mistake in tallship is setting the fps wrong

Both Big Buck Bunny and Elephant's Dream have banding in the source. Do you think we should add grain or such?

No- take 10bit source and convert to 8bit with Xscaler filter (or GradFun2DB) to have nice 8bit source for encoding

OK, will redo the encode with that source after making sure there's no banding issues.

Video with banding would give bad impression about whole Demo Disc

Mirroring of 32pixels (16 are sometimes not enough; try with a strength of 200 and search all along the video, you will see)
Second stage with 28pixels mirroring because it's not the same effect (a kind of shifting something, I don't know what, I'm not expert enough; try with a strength of 200, you will see) and is REALLY a nice complement/addition to the first stage.
Strength at the minimum (1.001) is enough for two stages filtering.

Code in my next post.
Hope that can help for quality's project.

[MatLz]

function dbd(clip DBDIN,float "str", int "mp")
{
str=default(str,1.001)
mp=default(mp,32)
DBDIN
stackhorizontal(fliphorizontal(crop(0,0,mp-width,0)),last,fliphorizontal(crop(width-mp,0,0,0)))
stackvertical(flipvertical(crop(0,0,0,mp-height)),last,flipvertical(crop(0,height-mp,0,0)))
crop(gradfun2db(str),mp,mp,-mp,-mp)
}

source
dbd()
#<- good place of a sharpening if it's needed
dbd(mp=28)

I noticed that Elephants Dream is 1080p @ 24000/1000fps. Is this allowable on Blu-ray?

[sneaker_ger]

Yes. Pretty much every movie released on Blu-Ray has that format.

Actually pretty much every movie is 1080p @ 24000/1001fps.

From the GIT commit:

Furthermore, note the Blu-ray spec has very strict limitations on allowed resolution/fps combinations. Examples include 1080p @ 24000/1001fps (NTSC FILM) and 720p @ 60000/1001fps.

[sneaker_ger]

Ah, sorry, saw so many numbers that my brain assumed 24000/1001. But 24000/1000 is also allowed.

Well I am not an expert, but I have authored a few BDs with TV show episodes, family movies, menus/sub-menus, with/without subtitles, ... I use Adobe Encore CS4.

While I am pretty much useless with the art stuff, I am *confortable* with the authoring itself. I seem to understand that is what you are looking for.

Another thing is that I'll be on vacation april 14th - april 30th thus unable to help at that time.

Also make note that the projects for 10 bit and/or 4:2:2/4:4:4 processing get the priority they deserve in the upcoming GSoC
[/offtopic]

Until then: Wow, this is a huge milestone for x264 in the making

It's stopping at 63%, my mux is going to 33% almost instantly,
after, big ts file begin, during this, i'm switching screen/keybord on my other PC.
But, it seems that this 63% are the end of the file, wich is the black rolling ending credit.
Problem seems only to happen with nal-hrd cbr, wich is not to be used, according DS.
Last encoded with 2 pass asking for bitrate=max=40000, with faster parameters on 1rst pass, and nal-hrd vbr, give me better expected bitrate (around 38800), than one pass with asked bitrate at 39000 and nal-hrd vbr (result was 33000). My last encode (the 2 pass) muxed fine yesterday evening, so, actualy, nal-hrd cbr is not BR compliant, but nal-hrd vbr is. That's my conclusion, and i'll stop my tests wich take 18h each time !

[shon3i]

@jpsdr thank you so much. Btw Blu-Ray only requires Type2 HRD, cbr hrd is fine with BD too,
