Funky colour degredation. ing channels, properly, testing

andy

Weird freaky colour weirdness.

Problems with an XVID rip, the colour is really messed up. I have seen this before, when I was testing encoding on a tv capture. An image is attached. It shows mass discolouration. The colour channels degrade after time, then refreshed after an I-Frame.

Insight, I have tried it with the latest XVID builds, Nic (decoder and decoder/encoder (worth a show) Koepi's and had a go with ffdshow, but it refuses to work properly with any xvids these days.

Here is the pic... eek, wheres attach gone?

Insight?

*should have mentioned - all other xvids work fine. So do any other avi's that should.dar1us

Cooooooooooooooool

I need more beer

never had a problem like that, but i've seen divx encodes that do similar things.  I highly HIGHLY doubt this has anything to do with xvid but rather your methods of encoding or perhaps bad rips you got from the net?  And because you provide zero information on what is going on, i can only speculate that this has something to do with funky capture cards or you got this file from the net.  Just my thought on the matter.

Yupp, ALL infos missing, give yourself a strike for not reading those two tiny stickies in this forum

Looks amp; sounds like a rounding bug. Or the wrong decoder.

Koepi

I had the same problem with an old Koepi’s build (december 2002). The result was very good but when I read it with a recent build, there is this “funky colour degradation”. And of course, if I re-install the old build, it works perfectly.

So, as have said Koepi, I think it comes from a problem of decoder …

JS

PS:  this is my first post, so I have first to congratulate everyone who makes XviD so good !

ANY build of Koepi's or Nics, or FFDshow.

Eek, I lie, if I try the stable build of Koepi's, it works now. But this is not really ideal, I would like to use the encoding features of the new versions.

Player, any, failed in all. Codecs (builds) all, stable works, only one I have tested that works, I have tested about 10-15 differnet builds of koepis, going back in date order.

Any idea what it could be, I can give someone a sample, I dont know the encoding environment, what settings blah blah. If I did, I would include them in a bug report. Not really much to work on.

how can you possibly encode without knowing what settings you are using?  That's just crazy stupid.

Read the guides here and browse the forums for help.  Perhaps the newbie forum is more appropriate to get you up and running.  

Thats is because it is not encoded by me. I thought there might be an actual answer, all I have had is nitpicking about the report. I thought I mentioned that it wasn't an encode by me, I swear I originally wrote that, I could have removed it in an edit, this would have made things a lot clearer.

Simple question, what could be causing the colour degredation as shown in the picture.

Mango, I am not a newbie. It is not my encode. I am encoding fine, just this playback problem.dar1us

Looking at that picture, to me it seems pretty much like the qpel-bug of some stone old  XviD build.
Did you already try checking the qpel workaround in ffdshow/miscellaneous?
