mp4

zest, it's really quite something special, that thing you're not getting.
zest, what's wrong with mp4?
dodke : There's nothing wrong with your televi... No wait... Strike the last one. There's nothing wrong with mp4. :) You should ask yourself "what's wrong with Zest ?" instead.
Let me explain it to you : Zest has a mental condition called "Acute ChickPics Posting Syndrome" (ACPPS). It means that everytime Zest sees something that sets on fire his orbito-frontal cortex (i.e. a girl in a cute position, in a bikini, or anything alike...), he HAS to post it on Pouet. He feels COMPELLED to share it with his mates. Any attempt to repress this compulsion would result in strong despair and utter feeling of sadness for the subject.
Zest doesn't bite, he's very kind, he's a lovely boy. It's just that he likes to post pics, is all. You may now proceed with the original discussion. Thanks for your attention.

mp4 is a cheap attempt by you-know-who at exploiting mp3 popularity to resuscitate the unpopular quicktime brand through misnamed podcasts and ipods for white sheep...
mkv is the real open-source deal :p

tom: i was just posting the MP5 that this girl happens to hold proudly :p
Zest : Don't apologize. I know about your ACCPS. :)
ACPPS, my bad. :)
if mp4 is so awesome would some please tell me how can i normalize the volume in one ._.
other than demux, normalize, remux?
that would work
Is anyone aware of a way (documentation of format / tools) to adjust the values in the stats file x264 writes for the first pass? With Xvid you can define zones where you can manually adjust the bitrate of the video. I'd like to have something like this for x264 too.
I found something called "x264 stats analyzer", but it doesn't seem to work anymore, probably because the file format has changed.

*bump*
FYI, the stats file format is:
in:%d out:%d type:%c q:%f itex:%d ptex:%d mv:%d misc:%d imb:%d pmb:%d smb:%d
in: frame number in display order.
out: frame number in coded order.
type: 'I'=>I-frame (IDR), 'i'=>I-frame (non-IDR), 'P'=>P-frame, 'B'=>B-frame (referenced), 'b'=>B-frame (disposable).
q: average QP over all macroblocks in the frame. (currently an integer since we don't do per-MB ratecontrol).
itex: bits spent on DCT residuals in intra MBs.
ptex: bits spent on DCT residuals in inter MBs.
mv: bits spent on MVs, refs, and partitions.
misc: bits spend on MB skip flags, slice header, and alignment.
imb/pmb/smb: number of intra/inter/skip MBs.
and apparently there's a "zones" option in x264 too:
--zones
Usage: --zones <zone0>/<zone1>/... (default=off) [b=0.01 - 100.0, q=0 - 51]
Zones allows you to override bitrate or quantizer at a certain point in the video. A zone is specified as:
Start frame, End frame, Option
Options are q=<integer> (forced QP) or b=<float> (bitrate multiplier).
To start a new zone you need a "/" before the new one begins. To see an example:
--zones 200,900,b=0.50/1000,1200,b=2.0
This means that frames 200 through to 900 will use approximately half the specified average bitrate, and frames 1000 to 1200 will use twice the average bitrate.

oh, and the new/old x264 VFW codec has a home here. The new version (721bm) offers a command line option too. neat.
