I have the same problem as Blue_MiSfit with the overquantization with 2 bframe enabled on anime contend. I tried to use both ffdshow and nero video decoder, they both showed very blocky frames. The only difference is that for the nero decoder, it looks like it have the deblocking on but it is turned off, while the ffdshow is showing distinct blocks.

Bug found. I can't reproduce anything that extreme, but some of my encodes do use B-frame quantizers significantly higher than I asked for. Now testing alternative ratecontrol methods.

update!

Hi everyone,

I just uploaded an updated version. Small changelog:
- uses core revision 88 - akupenguin has improved some speed and quality
- cosmetical fixes of all kinds
- some widgets get disabled when they are not active
- "x" button now closes the advanced dialog (works like "ok", not "cancel")
- first pass drops the bitstream. this also improves speed because we can skip some packaging stuff
- "load defaults" *probably* works better (I couldn't reproduce the problem but I think I know why it happened)


Stuff *not* fixed:
- no new widgets added (bframe ratio, stats file location, etc etc)
- no old widgets removed (still two settings for deblocker)
- still the same fourCC ("avc1" crashes ffdshow, because it makes ffdshow expect different packaging method)
- I never touched the core - second pass might still fail just like before

Have fun,
Radek

I'd suggest a clean uninstall and then install the new one. That's always the safest way not to mess up your Windows.

Re: update!

Second pass only fails with b-frames enabled. I tested your latest build and it seems to stuck at the last frame with avs2avi (1st pass).

I don't know much about AVC but the "quant" artifacts above are really more typical of a bug in motion comp pointing at the wrong reference blocks or frames. You can see it where little pieces of the image appear in the wrong places.

I've manage to create such bugs once in a while in my own coding on other projects.

As Ark said just use that mirror to get the latest build.
When itīs not too much work, it would be fine to have also the mplayer/mencoder win32 compile for the x264gui from doom9 on your side. Is this possible?

That's exactly what I meant in my last post, but I guess I could have worded it better...

np: Pan Sonic - Painovoima / Gravity (Kesto (234.48:4) (Disc 1))

- mp4box: I was sure this would work
- MP4UI: as expectet
as described in the container forum, its already possible to mux raw h.264 into .mp4 correctly with mp4creator (demux the h.264 stream from .avi with mpeg4ips avi2raw tool)
also you can mux h.264 in avi or raw into .mp4 with videolan (this is currently broken in the svn, but works fine here with an old compile i have here from july)
note that both tools will not work correctly with b-frames

thats strange. basically because till now there is no avc-in-avi content existing that uses the avc1 fourcc, so i wonder why it should expect special packaging in ffdshow? also i never had a problem with avc-in-avi using the avc1 fourcc...
is it only with b-frames?

two small cosmetic things, very easy to correct:

1) since rev. 86, subme=0 has been disabled. Needs to be removed from the gui.
2) in the About box, the "Visit homepage" button links to an outdated address. The new one is http://videolan.org/x264.html (file /vfw/x264vfw.h)

(btw @akupenguin: the "encoder features" list in that webpage is somewhat outdated, it doesn't list the latest additions to b-frames, as well as the 2pass RC and 1 pass const quantizer)

This is something I understand and can do. You think of this commandline donīt you:
mp4creator60.exe -c raw-avc-stream.h264 -rate 25 avc.mp4

But I cantīt find any explanation for this. In the whole threat everyone writes "demux with avi2raw tool". But how does this work. So I googelt to the avi2raw site and found this:
avi2raw -v mymedia.avi myvideo.yuv or
avi2raw -v mymedia.avi myvideo.rgb

I think for h.264 it should be
avi2raw -v mymedia.avi myvideo.h264

Is this correct?

avi2raw doesnt care about the extension and it will always output the raw video stream
so yes, you are correct

This is pretty clear now, thank you very much for your help. I often do not understand everything, so sorry for my many questions.

ok thats enough...
you asked for the same in the container forum, you dont want to read and understand my answer there, you dont want to read my mp4 faq to find out how to play .mp4 files (altough you posted there) and now you ask again for illegal stuff

striked for rule 6

I juts tried with a few dvd's and xvid files and the compression it's amaziing!!

I can recode a xvid file at half size of the original (350mb's) and the quality looks really g00d.
