Thanks to Richard it does now

Anyway, I updated avisynth.org. I added "troubleshooting" to the main page - wrote some stuff for it - moved the wiki-stuff to the bottom of the page - added a description of vdubmod - updated some other pages.

I instally AVIsynth 2.5 and VDmod 1.4.13.1. I get the following error.



If I do a ConvertToYUY2() or ConvertToRGB() it works fine. I thought VDmod was supposed to support YV12 video. I unzipped all the DLLs into the same directory as VDmod. I presume that's where it is supposed to go (seeing as there were no instructions).

Any ideas, or tips?

Putting all the dll in the vdubmod directory is the way to go.

Maybe you need either the unstable xvid build or dvix 5.02.

Ok, now I can see the output footage (after installing Divx 5.02), but why it is shown as the wrong size vertically and horizontally when it's shown in VDmod?

Edit: Nevermind. This is a VirtualdubMod issue, not an AVIsynth one. I'll ask over there.

Would someone be so kind as to email me a copy of the latest Avisynth 2.5 DLL, or attach it to this thread? I have been trying to reach cultact-server.novi.dk page all day but can't get a response (traceroute gives up...). I'm trying to get some test jobs set up before going to bed in about 3 hours.

If someone has it mirrored somewhere already, I apologize. I searched the forum but didn't find it.

This filter functions (exactly TemporalSoften and SpatialSoften!) are built-in in Avisynth 2.5

Yes, but only TemporalSoften works also in YV12.

When i try to click on the link for Decomb I get this message

I know it's a sticky on the main forum, but im not sure if thats what you were linking to.

I also get the "no permission" message when I click on the Decomb link in the FAQ.

I guess you actually want to link to this thread? http://forum.doom9.org/showthread.php?s=&threadid=41943

[Wilbert]

Yes, you are right. I linked to the wrong page. Thanks!

@theReal: Anybody can edit these pages :-)))

i noticed that divx encoded with fast recompress sometime have a bigger size than the same divx encoded with normal recompress,
but sometime size is the same.

Has this something to do with YV12 conversion??

[sh0dan]

... yes - the YV12 -> RGB -> YV12 conversion sligtly blurs chroma, and since the conversion isn't lossless, the luma also gets slightly altered. So you get reduced quality (bad) at reduced size (good) and decreased speed (bad) - it's your choice!

[movmasty]

another thing, Yv12 cant be used in interlaced sources,
since some dvd is interlaced, then there are 2 different dvd standards?(Yv12-yuv2)

[hakko504]

@movmasty
Read this thread for an explanation of how YV12 is handled in interlaced video.

Maybe it's nothing but...
I have a divx 3.11 alpha raw anime file. (lomotion)
when I try to open it using avisynth 2.5 & avisource,
Vdub tell me that codec used is RGB32 uncompressed.
When i add a convertToYv12() at the end of script
I ends with codec= divx5.02...

for playback default (and decoding if i'm not wrong)
I'm using divx 3.11 alpha and not divx5.02.

So here my question, is it just some weird error that tell vdub
he is decoding a divx5.02 file, or does avs really use divx 5.02
to decode 3.11 file...
In this case, it will be bad because divx 5.02 decode div3 stuff unproperly sometimes.
