Demos that miss captures but should have one.
category: general [glöplog]
well , i tried em many codecs and settings last night, i kinda dont know anymore...
i know i had a kkapture resulting in 9 files 1gb+ big at one time, which i immediately deleted...as other kkaptures had the same amount of quality resulting in 1.8gig-files.
i kkaptured and downsampled earlier prods via virtualdub already, had no problems at all..i just think the visuals this time arent any good compressable at all.
the resolution-selector is coded by gargaj and i have close to no idea of windows-code and dont wanna dive into it...need to prepare for work finally, which is more important i´d say ! ( after 14 years of unemployment ! )
so maybe realtime is for realtimers only :/ ( code_too_advanced-error in line 1 )
about the sound: if you had no problems watching earlier trsi-4ks, this should work aswell, its 4klang by gopher/alcatraz...i dont dare to change anything on that.

In know the noise in the images makes it damn hard to compress. With h264 at ~640x480@30fps you should be fine with ~3-4Mbps I'd say. Not really small for a 4k, I know.
Oh and set all options to the slow, but good quality side...
I guess the trick for the really difficult videos is to use x264 and set a constant quantizer instead of a bitrate. And as others have said, --preset slower or similar. :-)
i tried to install x264 but it never appeared in kkapture/virtualdub :/
so i made another crappy x261-vid instead and maybe you all realize why i didnt want to release such shit ! ;) ( my last comment makes it all clear else ! )
gonnappearsoonish at the prodspage !

I'm currently using this small batch file. You'll need x264, faac and mp4box in the same dir, also VirtualDub and optionally AVISynth need to be installed. Just fill in the SET commands with the right values and start.
There are of course lots of additional options you might or even need to set in special cases; the minimum set given in the batch file gives quite nice results tho.
I'm using AVISynth for concatenating/cropping/resizing the AVIs I get out of .kkapture (also, it's the only way to use Lagarith for kkapture output, as x264 doesn't support it as input yet).
Also a warning: "--preset slower" is serious business. Start the batch file, then go to bed or do anything else that doesn't involve the encoding computer for a few hours. Really. :)

Code:
@echo off
set INPUTS=c:\loldemo.avs
set OUTPUT=loldemo
set FPS=30
set BITRATE=5000
set AUDRATE=128
set X264OPTS=--profile main --preset slower --fullrange on
echo VirtualDub.SaveWAV("%OUTPUT%.wav"); > temp.syl
%ProgramFiles%\VirtualDub\vdub.exe %INPUTS% /s temp.syl
del temp.syl
faac -b %AUDRATE% -o %OUTPUT%.aac %OUTPUT%.wav
del %OUTPUT%.wav
x264 --pass 1 -B %BITRATE% %X264OPTS% -o %OUTPUT%.tmp %INPUTS%
del %OUTPUT%.tmp
x264 --pass 2 -B %BITRATE% %X264OPTS% -o %OUTPUT%.264 %INPUTS%
mp4box -new -hint -add %OUTPUT%.264 -add %OUTPUT%.aac -fps %FPS% %OUTPUT%.mp4
del %OUTPUT%.264 %OUTPUT%.aac x264_2pass.log x264_2pass.log.mbtree

uuhg, well !
this one speaks in languages i cannot....
kb:
well, thanx for tryin to help, but:
maybe you better visit MAIN and show me ??!! ;)
and i thought i could get a coder at some point ;)
( bring Denise btw ;) that Amiga-chip...NOT ! )

The only way to preserve quality is not to use average bitrate or 1/2-pass but use x264's crf mode. I'm using -crf 16 for mindcandy 3 but -crf 24 should be fine for most purposes.
Install AviDemux, choose MPEG4-AVC video, FAAC audio an MP4 Container and you should be fine.
Should use CRF too maybe... :/

trixter: crf sucks for streaming tho. At least I hate it when it looks like my net connection could handle the vid but then breaks down as soon as the visuals get complicated. But yeah, for HD/Bluray storage you're definitely right.
And hArDy: How come that everyone is always assuming _I_ know all the girls that hang out at demoparties? Sheesh. :D

coz girls like boys who play with Barbie(TM) ;)
"You see the clever girls look for clever boys
And then the clever boys seem to have a different choice
They want a good-looking chick
That likes to blow them away
Someone who laughs at all the
Funny little things they say"

kb: Do you want a video for streaming or a video that looks close to the original?
My point is that you usually can't have both.
