Well, I've spent two hours to find solution how to encode anime, but now I'm totally confused. Thats why I want to ask few simple questions.

The movie is Tom & Jerrys Greatest Chases. Its DVD and the source is (imo) very noisy, PAL, 4:3.

1. What is prefered compresion 1st pass test % . Is it like normal movie 65-75%

2. What is the lowest recommended resolution for anime. Using Medium noise in GKnot (SpatialSoftenMMX and TemporalSmoother)and lanczos resize I must go to 464x352 to get 50% in compression test (note that with soft bicubic resize compr. test increases with 7-8%)

3. What filters and in what order to use them to get maximum possible quality staying for 1CD rip (the sound is mono AC3 and even comressing it to MP3 doesnt give me much more space for video stream - ~50MB)

Ty in advance for your attention and patience.
Btw. some info: P4@2,3G/Divx5.02/Virtualdub 1.4.13- P4 mod/Avisynth 2.07

1. The numbers you'll usually see recommended are 60-75%.

2. Don't know about the resolution, but Lanczosresize is only recommended with really high comp. test values (I only use it if I find my resolution to be high enough and comp. test value at 70+%)

3. Some filters that comes to mind: Convolution3D (which could replace the medium noise option you went for) and Dup (which should be really useful for anime and cartoons). Check for avisynth forum for more information about those.

Just a note with your audio since the source is mono i assume your only encoding your mp3 to mono but also check that u use half the bitrate for example if u normally use 128kb for stereo mp3's us 64k for mono.

I only tried Anime (with XviD), not other sorts of animation, but I think you might be able to go for lower compressibility-percentages, here. (BTW, in XviD B-frames work nicely with animated content. ;))

Are you serious? anime needs more bitrate than usual movies.

@ amoeba
Sure, but for mono I'll rather stay by 80kbps, because 64kbps sounds quite bad.

Please don't give the sacred name that is "anime" to a cheap US *cartoon* (it's not that I don't like tom & jerry, I always watched it as I was young :D)
Anime is japanese only! :devil: (well, I rather call it Manga, because it sounds cooler/more appropriate than Anime, but unfortunately I'm not the one who's gonna tell the japanese how to call their productions :D)

I am serious. Of course it vastly differs depending on content, be it real-life or animated movies. Perhaps chromaME in XviD helps a bit. BTW, some people like to smoother Anime to death but I wonder if they tested how much it actually gains them in compressibility?

:scared:

OT: Anime is short for animation. They call our cartoons anime. (They love Powerpuff Girls.) Manga is short for mangahon or mangazasshi a comic. There is a difference. (Stupid US Manga Corps.) You can of course call it the aged Japanimation name, which isn't used anymore. But all animation is anime. :p

Sorry about going OT.

Personally, I use temporal smoother and smart smoother for anime. I want to give that convolution3d a try... Just avs still is kind of new to me and I don't know how to tweek it.

OK, then it's all Zeichentrick to me. :D
