DivX 5 blur problems

[Elpin]

Hi, i have a problem concerning blurring. Everytime i encode a DVD movie or an uncompressed video input into DivX, the result is very blurred even when i dont resize the movie and set the bitrate to 8000kbps! I dont know what to do to eliminate this. Ive seen many movies in DivX and every single one of them is very sharp and good quality even with low bitrate...
How can i eliminate such blurriness? Thank you for any help.

Hi and welcome to the forum-

We'll need a good deal more information in order to help you; NTSC or PAL, Force Film in DVD2AVI or not, sample .avs script and DivX settings, log file if using GKnot.

Have you done your homework by reading the guides and searching the forums for other threads about similar problems?

Yes, i was looking for it on the forums and yes, ive read the guide how to compress DVD into DivX with use of Gordian Knot (i downloaded the guide from here - doom9.org).But my problem is more common. I get the blurred "avi" every time i compress anything (uncompressed video,DVD,MPEG1 etc...)with any program (Gordian Knot, DVDx, FlaskMPEG, DVD2SVCD etc.) and with any input settings (PAL, NTSC)

Dont know what more i could tell you... maybe this example can say it all: I open an MPEG2 stream in DVD2AVI program, then i select "save AVI" and save it in DivX 5.0.5 format with 8000kbps - no resizing, no cliping, 1-pass, no deinterlacing - everything is on default. The result is blurred and sometimes there can even be seen those "squares" the image is built of...It seems to me like even when i set 8000kbs 1-pass, the codec uses lower bitrate...
Oh and the setting of DVD2AVI is also default -> iDCT Algorithm - 32bit SSE2 MMX, Field Operation - none, Color space - YUV, YUV->RGB - PC Scale

Hi-

Yes, it does seem that way if you're getting blocks even at 8000 kbps. So that might point to a bad installation or something else peculiar to DivX 5.05. Are you also getting small file sizes? With unresized video, at that bitrate, the file size might be around 2-4 GB, depending on the movie, and it sounds like you might be getting only 500 MB or so. To confirm, I might suggest trying another codec for testing to see if you get the same problem. Instead of saving the .avi in DVD2AVI, maybe save a project file. Use GKnot to open that .d2v project file and to make an .avs. Save that and open it directly in VDubMod and then do a 1 Pass-Quantizer at Quant 3. You can do that at default settings, but you can follow Doom9's Guide, or the Newbie Settings Guide (http://forum.doom9.org/showthread.php?s=&threadid=53136) from the XviD Forum. You can abort it after 5 or 10 minutes to check if it looks normal or is still blurred. If that one looks OK, then remove and reinstall DivX 5.05, and instead of encoding through DVD2AVI, maybe do it through GKnot, following Doom9's guide.

I kind of hate to promote the use of XviD in this forum, but as I said, it's for testing and comparison. And I'm not sure that removing and reinstalling the codec will fix the problem, as I don't really have a clue as to what's causing the blurriness. Maybe jggimi or SeeMoreDigital or someone else has a better answer.

Hi, well, unfortunately, i tried different codecs and the result is same. It seems to me im dumb or something, because i get a blurred result with every video compression ive ever made, even DVD format into SVCD. Ive tried many guides telling me how to compress video and i always get a blurred result and they sharp...
About the filesize - yes, the file is big - about 2GB per hour of the movie.
But ill try that "Newbie Settings Guide" and the procedure you wrote and see if it gets any better...

Thanks for help.

Hi-

Yes I noted that you have the same problem when encoding SVCDs. That kind of contradicts my theory that it has something to do with your DivX 5.05 installation. So, when you've seen other people's clear DivX rips (are they all DivX or perhaps XviD or DivX3.11), it's on the same computer (searching for video card or drivers solution)? Have you tried different players (searching for player solution)? Have you tried decoding with ffdshow (http://www.doom9.org/Soft21/Filters/ffdshow-20021213.exe) (searching for decoding solution)?

Good Luck with XviD, but I, as you, am not real optimistic that's the answer.
