Ugly fades.
I never saw that ugly fades in x264. I use buld 1046 from MeGUI Auto Updater and these settings

Why do you use maxbitarte 15000? Level 4.0 allows 25000! What happens if you remove --keyint 24 --min-keyint 1 ?

Post an output stream.
Also, does the problem disappear if you don't use threads, or if you use this build?

Well fade is particular part for H264 ... Try without --b-adapt 2 or --weightb. Fade is really particular problem for x264.

The problem here has nothing to do with H.264 or x264 in general, or even fades in general, but rather just that the frame quantizer is being shot up to QP51 by something (probably VBV). |

Well certainely bitrate efficiency but certainely not for the quality. All the other H264 encoder make history better job for fade (Ateme for exemple) with native WPred support for Pframe. For my BD encoding I must often use zone option for improve bitrate in fade part.

I knew I was right.. and Sagittaire, blocking in fades really isn't a problem anymore, and if so, one could always opt to use a cqm, but you can see that I haven't even recommended that to him. The only time to use a cqm for fading, is if one chooses to use noob settings.

Wouldn't the Max bitrate for BD-5 be around 30000?
The max data transfer rate for DVD is about 11000. BD-5 has a spin speed of 3x's... so max would/should be about 33000.... account for audio.... about 30000

Not helped only solution i found is to encode this first 300 frames with Mainconcept Encoder, and whole chapter now look good.
@Dark Shikari, can you do something about this? I remember when elecard encoder haved same issue in some of first versions of converter studio, and i reported it to Mutek, and they are soloved very quickly |

Also, if it turns out that build doesn't fix the problem, I'm going to need from you the smallest possible source segment and associated x264 build and x264 settings that replicate the problem. |
