how to remove codecs

[zahidism]

My xvid codec installation process has been a mess so far. Currently I'm using Koepi's binary and for some reason the quality sucks. I play the xvids in winamp and it skips frames whenever there's fast motion and the picture seems pixelated. keep in mind i have a 2.0 ghz pentium M dothan and 1 gb ddr3200 ram so I doubt my system is the problem. can anyone tell me how to remove codecs so i can start afresh and possibly tell me which codecs to install (someone told me Koepi's was old...where are the new Xvid builds?) Thanks.

Just a thought, maybe the terrible quality videos you're talking about were encoded poorly? Maybe with a too low bitrate, and with frame skipping on?...
To remove it you can just choose "Uninstall" from the XviD folder in the Start -> Programs menu. Or if you can't find it there, from Add/Remove Programs in the Windows control panel.

1024? is that a low bitrate? no these files play smoothly on another computer with xvid but i cant figure out what's different. it has to do w/ the codecs or something.

Well, 1,024kbps on certain clips can often be a very low bitrate. I have a "simple" looking 30fps 640x480 clip taken with a Canon S2 camera (not even a conventional camcorder) which looks bad when encoded with a bitrate below about 7,000kbps.

You could try decoding with ffdshow. You can get a recent version with SSE optimization enabled from http://www.x264.nl/ .

Is the other computer they play fine on yours? Maybe there is post processing enabled on it so blocking is less apparent.

Winamp is certainly not the best video player...

im using vlc now. any reason i should get mplayer? what exactly is post processing. i put it to highest i dont really see a difference. plus, i dont exactly see blocks. what i see are something like rendered lines as in the edges of the moving parts seem like im playing them on a playstation using that rendering engine.

anyone know a good ffdshow build is optimized for sse2

[Sirber]

PP is supposed to be only used to remove blocks. If you don't see blocks it can only lower the quality.

VLC ~= mplayer

Now I get it.. What you're seeing is most probably the interlacing artifact :|...
You don't have to use VLC, or MPlayer or any non directshow based player, that's not what's gonna magically solve all problems.
In ffdshow's "video decoder configuration" go to "deinterlacing" and choose either one of the "interpolation" or one of the "blending" options and see what looks best, that should solve your problem.

ooo, hmm. i did it in ffdshow but something is alarming. no xvidcore? wtf? (http://img388.imageshack.us/full.php?image=untitled3qr.jpg) it says i dont have xvid core. now...where do i get that from. i had koepi's binary but someone said that was old. sorry for the newbish questions but when i used to use xvid for some reason it seemed a lot simpler. thanks for your help. also, does ffdshow have any bearing on vlc?

edit: i installed the xvid core from www.xvid.org but it didnt help the de-interlacing when i play it in VLC.

edit2: what the heck is libavcodec in relation to xvid?? why does ffdshow use it as well as vlc.

libavcodec is a multipurpouse decoding and encoding library. it can decode many fomats including mpeg4-asp (xvid, divx, 3ivx, nero digital, etc.)
Set ffdshow to use libavcodec to decode xvid and it should work without asking for any xvid related stuff.
