Denke da schreib ich kein Wissenswertes extra dafür, da die Features ja den vfw Features entsprechen.

Zitat von JoeB

Ausserdem wird berichtet, dass der Encoder auch problemlos mit der xvidcore.dll für Dual Core umgehen kann.

Hmm, da bin ich skeptisch. Ich weiß nicht was Squid am Quellcode geändert hat, aber bisher war encraw statisch mit xvidcore gelinkt. Von dem her würde dir eine
andere xvidcore.dll nichts nützen. Und da die Aussage nicht von squid kommt, wäre ich da etwas vorsichtig.

Wie lautet die Line für max Quali? Ich habe einige (anamorphe) Tests gemacht mit denselben Einstellungen wie bei VirtualDub. Bei xvidencraw war die Quali übelst schlecht, hab prakatisch nur noch Verpixelungen gesehen. Die Quali von VDub war wie immer herrvorragend.

Das war die Line:

xvid_encraw -i ana2.avs -avi ana.avi -type 2 -pass1 xvid.log -max_key_interval 250 -turbo -quality 0 -frames 20000 -par 4 -nochromame -notrellis -qmatrix matrix.txt
xvid_encraw -i ana2.avs -avi ana.avi -type 2 -pass2 xvid.log -bitrate 2176 -max_key_interval 250 -vhqmode 4 -quality 6 -bvhq -nopacked -noclosed_gop -notrellis -frames 20000 -par 4 -qmatrix matrix.txt

(Die eigene Matrix benutz ich immer, an der liegts nicht)

"Wie lautet die Line für max Quali?"
1pass mit konstantem Quantizer 1 sollte da passen

Thx, mal testen

EDIT:

Da ich eine eigene Matrix benutze, muss ich

-qtype integer

nicht angeben, oder?

Ich meine keine Zonen sondern die

"Quantization type"

-H.263
-MPEG
-MPEG-Custom

Funktion.

Die findet man im "Profile @ Level" unter "more" in der XviD-Config unter VDub. Ich benutze immer MPEG-Custom und wollte wissen, ob man bei xvid_encraw zusätzlich noch -qtype angeben muss oder ob die Option -qmatrix reicht.

probieren geht über studieren

neues Build von squid_80:

Zitat

New build up. Actually there was a newer build up over 24 hours ago, I just updated it again. Nothing real groundbreaking:
-size option (help text is formatted wrong )
-pass1 and -pass2 can be used at the same time even though I couldn't get any improvement from nth pass
-interlaced option has support for TFF
-threads option is implemented and should work when support is added to xvidcore
- information about detected xvidcore version is displayed
-progress option, which I added in about 2 minutes because I was sick of watching the scrolling text output. It's a bit buggy.
-vfr option (not in help text) which should drop n-vops from mkv output streams and make the stream vfr. Haven't played with it much but seems to work.

Edit: Forgot that I also fixed zone handling to sort zones properly.

gibts denn hier schon mal ne neue Version oder so? Wenn ja, könnt Ihr mal ne MD5 Checksumme mit angeben?

ach wie geht des mit dem Carton Modus? Oder wo gibts alle Parameter zu sehn?

DANKE schon mal.

Oder wo gibts alle Parameter zu sehn?

hust.. hust...xvid_encraw /? .. hust.. hust Ist für jedes Kommandozeilenprogramm immer das Gleiche und Basiswissen

neues Build von squid_80 - sollte nun von MeGUI unterstützt werden:

Zitat

I think the only problem with using my build is that I unwittingly changed the -bitrate parameter to kbps instead of bps. I recently made a patch that should fix this problem (unless you use a bitrate < 10kbps or > 10mbps). Try replacing your xvid_encraw.exe with this version: http://okejl.dk/dunstan/xvid_encraw_megui_test.zip

But be warned it's my current development build, contains some pretty dodgy stuff. In particular make sure the input is YV12 because unlike the original encraw it won't complain, it'll probably just crash. MeGUI should probably take care of that anyway.

Let me know of any problems and I'll see what I can do.

I *think* I fixed that bug by reordering the size->bitrate equation to prevent overflow. I might be mistaken since I can't remember what it used to look like. Try it and see.
This build may contain unfinished code too, since it's my work-in-progress build. In particular, make sure the input is raw YV12 (you might get away with a compressed avi that decompresses to YV12 by default) because it won't throw an error if it's not - you'll just end up with a) garbage b) a cropped picture or c) a crash
For the adventurous, you can try making a packed .avi output file using -timecode <file> where file is a matroska v2 timecode file (like the one dedup spits out, for example). The .avi file should have dropped frames inserted to make up the time differences between frames.
