x264 for BD encoding - does it work now?
I've been pouring over the forums and it seems like there's been quite a bit of progress lately in adding BD compliance to x264.
From what I can gather, a compliant stream needs both --slices:4 (in the svn since early September) and --hal-nrd (patch available for some time, being worked into the SVN now). Is this accurate? If so, has anyone released a binary with both of these features activated? Have the results been tested for replication? (BD is a bit of a mess, since authoring successfully doesn't necessarily mean it'll replicate OK.) Any assistance would be really helpful. If replication hasn't been tested yet, I can get some test encodes submitted to a plant to find out. |

Awesome. Can I anticipate some noise being made when it passes?
I can't wait to put this into use. The encoder built into the new version of Compressor is... acceptable, but really chokes on noisy sources. Everything else is way out of my price range. T_T |

lol, ImaginAsian is not even a company anymore. I work for Anime News Network, but I also do freelance DVD/BD authoring on the side. But even if it doesn't replicate successfully yet, I have a few personal projects I can put it to work on.
I don't need to use it with Compressor; honestly I'd be thrilled if I can use it as a CLI on either Intel Mac or Windows. I guess Windows would come in handier, since I could feed it AVIsynth sources, but the Mac version would really come in handy too. (I'm stuck with XP, so multithreading is not gonna go all that fast for me on the Windows side.) I'd be most grateful for either one. Last edited by jsevakis; 25th October 2009 at 02:00. |

Among other things, MPEG-2 is still required for interlaced coding. |

Agreed that it's a meh h.264 implementation at best, tho. |

Does the latest patch from Alex Giladi work? Trahald says that Alex's patch is much better and that we should get that one into git, not his.

No , but i test only two builds posted here i don't know is there maybe newer since then. I tested many times and both scenarist and elecard reject stream, second time is more strange. If you want to do something about that i will test if need. Even Trahald last rev19 crashes x264 if --keyint 24 is set, with --keyint 48 work fine.

This is preaty impossible- extracted streams have to import and mux (even if BDs were created with Blu-print). It means there is something wrong with extracting. |

BD verifier is not available in any trial/demo version- as far as I know. You can have trial version of Blu-print, but you need a company which has to go through credit check process. If you make discs which are replicated in thousands copies, you have to be sure about your software. If stream from x264 passes one verification it still doen't mean it can be safetly used for commercial use. We would need at least few tests with different settings and options used for encoding.

There can be possibility that new version had bigger restricions, so some streams may not mux- I don't know. I don't use 30Mbit for buffer, but slightly less and never had any problems with muxing, even if my assets peaks close to the limit. Andrew |

Maybe it will become something to consider once everything else on my list is done, but with most television channels eventually looking to move to 1080p60, interlacing will eventually be dead anyways. |

Hopefully by that time also there will be more (affordable) HD camcorders with 50p/60p recording capability. At present, there are just a few models in the professional lower-price bracket offering native 720/50p and/or 720/60p formats - Panasonic AG-HMC-150/151 and AG-HMC-40/41 (AVCHD) and JVC GY-HM100 (MPEG-2).

I think there is hope for NAL-HRD. But if you want MBAFF in x264, then it won't be cheap:

^You're talking to x264 programmers. The same programmers who IMO jumpstarted the whole anti-VFW crusade that still starts flame wars occasionally.
Needless to say, outdated legacy standards like interlacing aren't exactly going to garner much sympathy either. This shouldn't surprise anybody.
