Standard Def video doesn't need 40 Mbps to be encoded, even for max bitrate. In general level 3.2 or 4.0 is enough (maxrate is 24 Mbps) and this allows to have 1 slice only. It can be a matter of taste, you can encode anyway a standard def. video with level 4.1 and 4 slices.

VBV would also be different in that scenario since DVDs usually don't have high enough transfer speed to support the full level 4.0 bitrate. Since you have lower bitrate you can also use 2 second GOPs. Going from 4 slices to 1 won't give much benefit, I'd guess way less than 1%, but every bit helps.

The new rev 1995 builds on x264.nl are 25.4mb... To me thats just a little large? 25.4MB! I didn't bother downloading it since there's something wrong with it.
(mirror01 didn't seem to respond, the other mirrors all came up with 25.4mb)... |

Is Simon Horlick's work on MBAFF now finished or are there any new things (except from optimizations and fine-tunings) expected?

It seems that I don't need to deint NTSC-30i any longer when see the changes of MBAFF if I encode just for myself by r1995...

Having followed the commit history for a little while now I'd been amazed at the output of this individual, and with the recent release (and an interlaced project I'll be interested to try with r1995) I had to look him-up. Apparently one of the things one has to do these days is keep a blog journal.
Altho I can bearly spel MBAFF I appreciate all the work! |

Can you post some test results? I've got a pile of DVD extras to encode as interlaced to add to my media jukebox, and I've been waiting for the feature to be finished

Is MBAFF generally poor (in x264)? Or dou you mean that it is now much better in x264 than Mainconcepts hence you can forget Mainconcept? I am still interested in doing interlaced (MBAFF) encodes. Thanks for enlightening me |

You must be using the wrong Google.
Second link I got from Google: http://www.urbandictionary.com/define.php?term=badass Interpretations 2 and 4 on that page would be a match to what Blue_MiSfit meant. |

Correct. It's a substantial improvement in quality (or even metrics like psnr if you optimze for that).
Some random hard 3:2 content picked up about 1 db in psnr in my fairly restrictive tests: 1.2mbps cbr 480i, short GOPs and small buffers as required for a specific client. 1db of PSNR is quite substantial, to say nothing of the visual improvement when using psy optimizations. Derek

Yeah especially for the user they don't have to care anymore if their content is progressive or interlaced content even both mixed on the same frame thus being macroblock adaptive will be equally well encoded that's a big plus of usability improvement in the encoding framework
MBAFF was the first step to have a Interoperability layer for old (analog TV age interlaced content) for moving on into the full progressive digital age without braking old analog concepts and still allow Broadcasters to save bandwidth if they want or need to put some more stations on the transponders Nice finally to see it it arriving in x264 after so much years

Did anyone test CRF mode yet? I did a very quick test and noticed that the previous build (without adaptive MBAFF) produced a smaller file with the same settings and CRF. So do we need to adjust CRF again to compensate for the changes?
