Code:
x264.exe --crf 30 --ref 1 --me dia --subme 1 --partitions none --threads auto --progress --no-psnr --no-ssim --output "<output.264>" "<input>" --nal-hrd Jdobbs: all the changes in the changelog look good and even the undocumented sub fix except with strict AVCHD output can it delete the CERTIFICATE folder in the next version? Also out of curiosity do you have any plans on what you plan to tackle next? Two big topics that seem to affect every encode are sizing and encoder related things (keep movie but encode extras, long gop, 1 pass crf using quality settings set, display x264 eta, x64 x264 (lower priority?))

Don't know what you mean by "long gop" -- BD has a limited frequency of key frames, even though my Sony seems to not care. One pass CRF with prediction is actually already written, but it was so inaccurate I disabled it. I'll get back to that soon enough. Last edited by jdobbs; 2nd June 2009 at 21:22. |

1 pass crf o the whole movie? I forgot about that one but I remember seeing it discussed somewhere but that sounds good as well. But what I meant by the 1 pass CRF using the quality settings was for extras. For example there would be under mode menu a '1 pass encode for extras' that uses QUICK_CRF set and the quality options set, then a sub option be 'quicker encode' to use what quicker encodes does now. Also with crf there is no need for the current --pass --stats x264 calls, it writes a stats that isn't used which may hurt performance a little bit. |

What if it's the thing that allows RipBot264 encodes to play with 24p enabled?
It is a good possibility but need to wait on tests. Long gop's have been well tested with RipBot264 over the past year or so without any issues, so it's nothing new. Why not an ini only setting for us power users? |

Long GOPs aren't Blu-Ray -- they are something else, no matter how well tested they are. You certainly won't find them on commercial BDs (if so, I'd be surprised), and a decent authoring package shouldn't accept them. I think its a bad idea. Last edited by jdobbs; 2nd June 2009 at 22:20. |

30p I think is only detrimental to the video stream but people will have their own opinions on that one. As some don't notice the non-fluid motion achieved by deinterlacing. Sliced H.264 x264 doesn't support so nothing can be done about that, I'm not sure what it is but I've read it can hurt efficiency. Long GOP can do nothing but benefit the video stream as long as the encoder makes the right decision every time, which x264 seems to do. In some cases in a huge way, those 2 clips I linked to are good examples of this. While I'd like to see an AVCHD/BD standard that has to be followed so we know what has to be done, it doesn't exist. In it's current state almost everything BD-RB does breaks the standard. A few examples: You shouldn't be able to play anything but AC3/LPCM AVCHD from DVD, full backups in their current state should only play from BD, in order to play from DVD they'd need their menu commands changed to be like that of AVCHD menus which will lose some advanced functionality, which may be a possibility some day, who knows.

Of the discs I have done, when played on a ps3 the two which were patched tried to play and then errored. The bd-9 one appeared as a data disc but when the main movie stream was played it did have the audio okay, so that could handle the audio if not the menus. |

http://www.sendspace.com/file/zxomlj This plays fine on a pc and the movie stream 0220.m2ts is okay on a ps3. On a Sony 550 the audio isn't available on the movie and the display information shows no audio and the audio button has no effect. If the files are burnt to a bd-25 then that plays fine. |

I have no trouble playing BD-RB movie only backups burned to BD-5 with 24p on my Sony BDP-BX1. So I have to agree with jdobbs that this does seem to be an issue that Panasonic needs to correct. At some point, a standard has to be accepted. I don't believe jdobbs should have to spend so much time trying to make adjustments for a mfg.'s player to allow play back of an AVCHD movie only to DVD media. I commend him for trying! If BD-25 works for these players, then that may be the solution. If the goal is to be able to make backups to BD-5 or BD-9, then a more compliant player should be mandatory. Buyer be ware! Test your discs before making a purchase.
We all know you have to meet certain cpu, video card, etc.. requirements just to play back Blueray discs on a computer, so we have to be as prudent with our standalones as well! If RipBot works, why not just use that program? |

mhammer: Could you try muxing an audio track with these 2 video streams?
It's the last things I can think of as differences between RipBot264 and BD-RB output. Last edited by turbojet; 3rd June 2009 at 06:26. |

Yesterday I was encoding Ghost Town. I stripped all other languages other than English to maintain the best bitrate. Original size: 27,4 GB.
After the encode was down I checked the new size, and it was 21,4 GB. Quite a waste of space, I ended up re-adding the stripped languages, as I had space left anyway. I checked the log, and noticed the target rate was exactly 25.000. I browsed through some x264 settings, and came up that this probably is because of a max_rate setting, set to 25000? I'ld really like it to be possible to change this setting, whether it is in the program or in the config file. Thanks in advance. |
