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.

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.

i have the latest Zarx264

[mirkosp]

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.

[AlexanderVonCross]

the resolution is 720x480 as for the rest im not sure. the audio is mp3

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.

post your script.

[AlexanderVonCross]

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