problem with decomb 4 beta6 and 7 (for avs 2.5)

[jarthel]

Here's the scripts I've used
-----------
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\MPEG2Dec3.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\Convolution3DYV12.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\Decomb.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\asharp.dll")

body=mpeg2source("e:\dvdrips\escaflowne5\escaflowne5.d2v",idct=5,cpu=6,iPP=true).trim(25000,26000).crop(10,2,696,476).Telecide().Decimate(cycle=5).lanczosresize(640,480)

return body

AND

LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\MPEG2Dec3.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\Convolution3DYV12.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\Decomb.dll")
LoadPlugin("D:\downloads\windows\utilities\divx\avisynth\plugins25\asharp.dll")

body=mpeg2source("e:\dvdrips\escaflowne5\escaflowne5.d2v",idct=5,cpu=6,iPP=true).trim(25000,26000).crop(10,2,696,476).Telecide().Decimate(cycle=5)

return body

Here's the screenshot

According to dvd2avi, the video is a mixed of interlace and progressive frames.

I have tried both avs2.5 (6-March release) and avs2.51 (13-March release).

I've tested the same script in avs207 and the problem is not present. Of course I was using avs2 filters. :)

I tried this telecide/decimate combo -->> Telecide(Guide=1,Gthresh=40,Threshold=20,Chroma=True,dthreshold=10,Post=true).Decimate(cycle=5) and the problem is still present.

I tried using fielddeinterlace only and the problem is not present.

Placing ConvertToYUV2() before Telecide seem to make it a little bit better (click here to screenshot from preview in vdubmod) (http://photos.yahoo.com/bc/jarthel/vwp?.dir=/divx&.src=ph&.dnm=escaflowne1.jpg&.view=t).

The problem is present in preview inside vdubmod. I encoded the video hoping the error only shows up in preview but the encoded video also has the error.

Thanks Donald. :)

Please post a VOB fragment that shows the problem. That is the only way I can help you. Also, you talk about "the problem" but never tell me what it is.

I am hours away from leaving for the airport to return from India via the Gulf 6 hours before the deadline expires (overflying Iraq!). Please be patient for my further reply and cross your fingers for me.:scared:

[jarthel]

is huffyuv of around 200 frames ok?

Well the problem can be seen when you look at the screenshot. I thought I was being clear when I posted a screenshot as looking at the screenshot better illustrates what the problem is. :)

ps. have a safe trip.

Thank you for the warm sentiments. I am now safely back after Lufthansa re-routed around the Gulf at the last hour!

@jarthel

If the source is a VOB, I'd prefer a VOB fragment. Otherwise, HUFYUV is OK if it is unprocessed and displays the problem. Also, tell me in WORDS what your problem is. :)

Waiting for your further materials...

Well I'm not sure if I'll be using the right words to describe the problem. But here goes...

Well as you can see from the screenshot, there's yellow "wash" on the face and the shirt. As can be seen on the second screenshot, the yellow wash is not as prevalent like on the 1st screenshot. The second screenshot was made using the same script but I included converttoyuv2 before telecide.

The yellow "wash" is not present when I used the same script in avs2 using the appropriate avs2 filters.

As I already said, I'm not sure if I used the right words to describe the problem but I tried.

Also I do not know how to extract a vob segment. so it will be huffyuv format unless I can find a guide to help me extract a vob segment.

Thanks

Jayel

ps. how do I send the video segment to you? email perhaps?

Well I don't have a website but I do have an FTP server.

I'll pm you the details.

Thanks for the help Donald. :)

I downloaded your HUFYUV test file. I am running Avisynth 2.5.1 beta and Decomb 4.06 beta 7. Here is my script:

loadplugin("d:\avisynthplugins\decomb.dll")
avisource("escaflowne5.avi")
Telecide(post=false).Decimate()

Other than some chroma rainbowing that is present in the source, I do not see any problem here.

I also tried your settings without seeing any problem:

Telecide(guide=1,gthresh=40,threshold=20,chroma=true,dthreshold=10,post=true)
Decimate()

Please advise if you replicate these results. If so, please provide a clip that shows the problem. If not, tell me how to demonstrate your problem using this clip. If you cannot demonstrate it with this clip, your problem may be YV12-related and you should provide a VOB fragment to enable me to replicate your problem. Thank you.

[jarthel]

Well you are right. It's not decomd. it's crop. :)

Here's the crop setting crop(10,2,696,476). it's a mod4 width.

anyway I'll create another thread. thanks Donald.
