im sure im going to get yelled at for this but:

Ok, so, I'm real sure this topic has been asked about many times on this fourm, so sorry for being repetative. I am trying to figure out how to make my amv's look better by using Vdubmod, i though I had it, but alas I was wrong, the file size was small, but the video quality looked like hell. It was either too blocky, or it had major rainbowing, i tried to use scripts and it looked like it worked, but when I played it back, i wanted to cry. I have also tried using the Zarx264 gui with minimal to no sucess. does anyone know if there is a better comppression tool out there that I can use? if not can someone please explain to me how to get the avsynth to work? I tried the help section, but for the most part its lost on me.
I have been told I have issues, I just say, no I have volumes...ususally they just shake their heads and walk away.

gonna need more details.
what scripts have you tried (and what errors are you getting?), did you do any footage processing (stuff like deinterlacing/IVTC) before making the amv? how long is the amv, what resolution, what filesize before and after compressing? which codec? any example images of the bad compression? any example images of before you get to avisynth?

As far as better compression tools, not really...unless you want to do stuff like checkout x.264 from git and run it on the command line (which I'm guessing you don't).

Zarxgui 1.32 is up to date with the latest (or almost) build JEEB made... some things are changed both in x264 and in zarxgui, so I'd say that the results should be satisfactory even at defaults now. Of course, depending on the content, tweaking a bit will help.

Mmmmh... what kind of content are you trying to encode? Stuff like resolution and amount of grain have a say in how effective the settings will be.

Mpeg2source, Deen, Derainbow, deblock, and undot. i did this twice, once was with an uncompressed file which was 2.8GB before, then after depending on which codec i used the sizes would vary. The second time i did this i used the Zarx264 avsynth file, and i got errors for deeen, and mpeg2source i took them out and it worked but when i opened it, it played slowly and was very choppy. After I compressed the file one version was very slow to play and skipped scenes its size varied between 1.5GB to over 100MB , another version was smaller at 55MB, but the quality was crap. When i used the Zarx264 sysnth, it looked like hell when i played it through vdubmod. The video looked aweful, its hard to describe what it looked like. Before I put it in avsynth it looked fine.

this is what i used:
MPEGSource(cpu=6)
Deblock(quant=25)
DeRainbow(10)
Undot()
Deen("w3d",3,3,5)

Mpeg2source is for loading a .d2v file. I don't even know if it can actually function without specifying one. If you are getting errors, that is probably the reason why.
Also, deblock(quant=25) is rather strong, and is probably killing the quality.
And wtf is DeRainbow(10)??? The only function that I know of named "DeRainbow" does not take any parameter.

Where are you getting this stuff from?

>deen
That's why there is no detail and it's getting blocky due to a bad AQ choice for such flat footage.

>vdubmod
At least use something current

>x.264 svn
I don't know where that superfluous dot came from Kariudo but there is no x264 svn. It uses GIT.

@AlexanderVonCross: chances are you're either using a terrible source, or are overfiltering it to hell and hence the quantizer is having a field day. I would assume both. With deen, cpu=6, deblock, derainbow, and finally undot, you have effectively removed ALL detail, both noise and otherwise, from your footage, and that is why x264 is going all RAEPRAEPRAEP on your video.

As far as the grain goes, why are you removing it? Grain is GOOD FOR YOU. It keeps the details in the video. If you get rid of it, you lose texture. You should only be removing grain when it is excessive (Phantom or Mouryou no Hakko or maybe Nausicaa are the only sources that come to mind for this), otherwise leave it alone. I think a lot of amvers have trouble distinguishing grain from noise. It's easy. Grain is uniform while noise tends to vary in colour and size. You just need to ease off on your filtering. See how a plain dgdecode_mpeg2source("my.d2v") and fft3dfilter(sigma=1.5) goes to start with. It's all about removing defects while preserving the rest. x264 actually does better on textured video than it does on flat stuff unless you throw a crapload of bitrate or use a smarter AQ on it.

Bad habit I guess.

Baw, I was hoping for an argument like "then why does it use r1800 or whatever for syntax? That's an SVN revision number and GIT uses hashes you retard!" but you let me down D:
