Quick Blu-ray content (BD, BD-5 and BD-9) authoring guide (PS3+PowerDVD)
Let's clarify something
What's a BD-5/BD-9? It's a DVD with Blu-ray Video content and structure Oh...an AVCHD! No, AVCHD has its own specs, mainly stated by: -Video codec: AVC -Audio codec: Dolby Digital, PCM 1.5 Mbps -More than one audio track: No -Subtitles: No -Maximum video bitrate: 25000 kbps -Maximum VBR buffer size: 9000 kbps While Blu-ray's (and therefore BD-5's/BD-9's) are: -Video codec: AVC, VC-1, MPEG-2 -More than one audio track: Yes -Subtitles: Yes -Audio codec: Dolby Digital, DTS 1,5 Mbps, PCM 27 Mbps, Dolby Digital + 1,7Mbps, DTS-HD 6 Mbps, TrueHD 18 Mbps, DTS-HD MA 24,5 Mbps -Maximum video bitrate: 40000 kbps -Maximum VBR buffer size: 30000 kbps Using this method you will get a 100% standard Blu-ray content, but bruning that content on a DVD (BD-5) or double layer DVD (BD-9) is not standard at all. Nevertheless, several BD players play them some of them considering them as an AVCHD (PS3)...but then plays as a normal BD, so all codecs and subtitles are supported Needed files and programs *Sonic.Scenarist.BDA.v4.20 *Nero's index.bdmv and Movieobject.bdmv(For PS3 BD-9/5 compatibiliy) *SubtitleWorkshop4 to include .srt subtitles *Supread to include Blu-ray (.sup) subtitles *nal_hrd patched x264 --For Windows get last megui's x264 build, it's already patched --For Linux, open a Terminal Konsole and: Quote:

Preparing the video With the nal_hrd patched x264 version, we use our favourite line/profile to encode the video, not forgetting these parameters in the final line: --keyint 24 --min-keyint 1 --vbv-maxrate 38000 --vbv-bufsize 30000 --nal-hrd --mvrange 511 --level 4.1 --bframe 3 --ref 3 --aud --sar 1:1 And forgetting: --b-pyramid Resolution must be standard and fps 24p, 50i or 60i By the way, with 50i and 60i you can chage --keyint to 25 (PAL) and 30 (NTSC), not sure about 50 and 60 in a true interlaced encoding... Preparing the subtitles The program we'll use doesn't recognise neither .srt nor .sup so you have to convert them. SRT: Quote:

Creating the BD You need at least Sonic.Scenarist.BDA.v4.20 Quote:
That's all, now you have 100% standard BD content, for burning: *On a Blu-ray: --Just BDMV folder on it *On a DVD: --PS3: Change index.bdmv and Movieobject.bdmv (in \BDMV and \BDMV\BACKUP\) for the Nero ones and burn BDMV folder on a DVD with UDF 2.5 format. --No AVCHD compatible BD players: Just burn BDMV folder on it? You can also: -Open the files with powerdvd's option “play Blu-ray on HDD” -Bring it to PS3 thru web server like Red Kawa or Apache (no subtitles neither multiaudio, just video+1st audio) Can I use this method to MKV->PS3Ready or should I always rencode? Rencoding is the only way to ensure 100% compatibility, but if you want, you can just try editing the header in case the video is already compilant but not properly advised. Get lasted h264info (at the moment I'm writing this is 0018) and fill with write PPS on: kbps bitrate: 38000 num_ref_frames: 3 (maybe 4 works too, haven't tried) Output Aspect Ratio: 1:1 Level: 4.1 WxH: 1920x1080, 1280x720...whatever it is Remember that just works when the video is properly encoded...if not...you can try but it most likely won't...that's why I don't like using it If it doesn't work DON'T TRY VOB/MP4/ETC TRANSFERS SINCE THEY'LL WON'T WORK TOO, only rencoding is the solution unless it's a resolution problem Mini-todo list *Confirm no PS3 players compatibility *Confirm theory: If you don't change .bdmv files on the Backup folder, BD players will look there after refusing the PS3's ones and play OK, so it's ALWAYS recomended to do that for BD-9/5, to ensure both PS3 and BD players compatibility EDIT: If you are new in encoding...get these blu-ray profiles for megui from one of this links http://rs91.rapidshare.com/files/900...y_profiles.zip http://www.mediafire.com/?f1zgyj5mn3n http://s000.tinyupload.com/index.php...03428493361575 Last edited by XolocoTuxmaster : 16th February 2008 at 17:24. |
