what is this?? massive shitframes with DivX 5!!!

[theReal]

I just downloaded DivX 5 Pro (the advertising version, of course) and encoded the latest (well, in Germany it was the latest...) episode of Futurama. My settings were almost as usual: the source was recorded in 640x480 Divx 4.12, 100% quality based, fastest compression, only keyframes. This source I sent through this avisynth script:

LoadPlugin("d:\programme\gordianknot\decomb.dll")
AVISource("e:\CAPTURE 01 .avi")
ConvertToYUY2()
FieldDeinterlace()
BilinearResize(512,384)
TemporalSoften(2,6,6)

opened this with Virtualdub 1.4.7 and 2-pass-encoded it with the new Divx 5 Pro, using the following settings (pretty much using all of the new stuff because I'm encoding Futurama episodes at a very low bitrate):

-b22 710 -psy 2 -key 300 -log "E:\divx.log" -mv "E:\mvinfo.bin" -b -g -q -dr 12,2,2000,10,20 -sc 50 -pq 5

Now I have a "little" problem with shitframes... almost bullshitframes if you ask me... but have a look, this is shortly after a keyframe, before the mess starts:

And here is what it looks like a couple of frames later, when the mess is the biggest:

You can see the whole scene in this short avi (http://www.computerfuzzies.de/picture/wholescene.avi) (528k)

Could it be the fault of the new "psychovisual enhancemants" that just don't work well on cartoons recorded from tv? Or what?

btw. this is not the only shitframe scene, there are quite a few more of them!!

did you read the readme? psy settings could lead to that.. the readme warns you from using them.. says you should only use them for short clips.. that's what happens if the marketing department dictates software releases

i had the same problem using a dvd source. but only when using 'normal' psy, and not when using 'light' or 'heavy' psy.

Known Issues
------------

* Psychovisual modeling may cause artifacting in certain types of video content. This issue will be addressed in the next release.


So basically that spiffy new feature doesn't actually work :)

I got some minor "shit" in a test encode with divx5 but I was using fast recompress mode so maybe it'd be ok with full processing. Not really impressed by the results compared to 3.11a. Quality is pretty much the same except they use more smoothing in playback (less blocks but less detail). Same old story.

did you read the readme?

I only read the guide, it said nothing about "this issue will be addressed in the next release".

I'm going to try the encode without the psychovisual setting, thanks for the info!

I didn't use PSY and I got that same shit.. Bunch of shitframes.. So whats the deal?

[Vanos_b]

I encountered the same problem, but not because of the PSY (that was always set to strong) but the quarter pixel (that in fact produced some artifacts too, besides these blocks, mainly in fade in/out scenes). After disabling it everything worked just fine. BTW: if you use qurter pixel in the first pass (as I did) you have to disable "use mv file" for the second pass (otherwise crash:angry: both in XP/98SE with Vdub 1.4.9).

damn i thought i was the only one who had this problem..
i guess im one of the few who still can do sucessful conversions with xmpeg.. as thats the program i used.. like i always do i set it up with my settings.. and the only thing i touched in the divx 5 pro is the bitrate.. i didnt fool with anyhting else.. and i got the exact same shitframes.. i was encoding boogie nights.. at first i thought it was because i got my release of divx 5 pro from cdrsoft.cc

I more and more dislike the developers of divx5.....they are getting more and more like a normal software concern (ms..)...

first they announce such GREAT new features, like a fantasticle new system, to make use of the fact, that the human eye can see everything, and then....anywere is written (very small, so you wont find it) , that it doesnt work yet....great work...we are all paying bugusers....normal bugusers are paid or test at least free software...

Hi,

Strangely enough, have yet to have problems like described when psycho-babble is turned to "normal".

Must be the movies I have done....Independence Day, Mr. Mom (I know, I know :) )
