Problem with x264 vide,I need help

[Romario]

Hi guys,I need your help.

I encodec video,today,with Avidemux 2.52 rev. 5955 with x264 rev 1371...and I have one BIG problem.

As you can see from file below, I used very detailed settings, but I have big problem with file, because ffdshow rev. 3281 can't decode my x264 clip very well.

Look into my file for clarification of my settings I used for encoding from MPEG2 source.

Thanks in advanse.

Above is settings I was used from Avidemux, in MKV container.


Please,download file and my settings from http://www.megaupload.com/?d=ARXVPSBN


I can't upload a source file for now

we all love very detailed informations like this...

Please,download file and my settings from http://www.megaupload.com/?d=ARXVPSBN
have you heard about www.mediafire.com

[Atak_Snajpera]

Probably source file is corrupted

[Romario]

Yes,but I most like megaupload :) Did you see the problem, Atak_Snajpera, in my encoded file ?

No,no,everything is just fine with source file,believe me. I can play it very well.

[Atak_Snajpera]

Why don't you just upload source then???

[Romario]

Ok,but it will take some time,in that case. Meanwhile,tell me your opinion about my problem,can you play my clip with ffdshow without problems ?

Be detail,please.

And I will upload the source,but you should wait a one or two hours.

[Atak_Snajpera]

send me source and then we can talk

[poisondeathray]

Can't download it

"The file you are trying to access is temporarily unavailable"

[Romario]

Try again,I just downloaded it without any problems.

Atak_Snajpera,don't worry,I will upload the source.

[poisondeathray]

^Yes it worked this time

It looks all pixellated in sections.

FFDShow has more artifacts decoding than Divx H.264 decoder, but still big problems

Did you do anything else in avidemux (e.g. filters, deinterlace, resize etc..)

We need to look at the source

[Romario]

Well,look resolution of my clip, I resize the video with Avidemux resizer(MPlayer resizer).

I hav't applied filters.Source is progressive,so I wasn't using deinterlace.

multimediaman,please tell me your personal opininion about encodec clip,I don't understand all this numbers.

For all, here is source MPEG2 clip: http://www.mediafire.com/?3zwmj2xr20m

[poisondeathray]

I tried with your settings, Avidemux 2.52 rev. 5955 , only difference was merange16, and it worked fine with ffdshow (well there were some jerks in the source), but no pixellation

The version I used was from here
http://avidemux.razorbyte.com.au/

Try encoding it again

[Atak_Snajpera]

no problems in ripbot either

[Romario]

Thanks guys,but I not get it, why ffdshow can't properly decode with my settings ?

What about CoreAVC,maybe he can decode my x264 clip without problems? Did anybody tried that ?

Thanks in advance.

[Atak_Snajpera]

did you try new ffdshow versions?

[nm]

Thanks guys,but I not get it, why ffdshow can't properly decode with my settings ?

Your x264 encode is certainly broken at bitstream level, so the problem has occurred during encoding. It could be hardware-related (overheating, memory corruption), for example. Try encoding with x264 CLI instead of Avidemux.

[Romario]

Thanks for advice,I will try,first,to encode once again with Avidemux.And,if clip isn't better,then I will try with x264 CLI.

Can somebody explan me this motion vector....I not get it completely.Why it's good or not good for motion vector to be on value 64, instead of default value 16 ?

[J_Darnley]

Do you mean me-range? The motion estimation range?

"Not good" because it is slooooooow and provides almost no benefit.
"Good" because there is a small chance it might find a better motion vector.

Only the veryslow and placebo presets changes me-range and then they only use 24. I don't see other very slow options being used so using 64 seems very excessive.

[Romario]

Yes,I mean on me-range,you are right. :)
