which codec you people use for anime nowadays?

[takeru]

i've been encoding anime with nandub for a long time now, and was wondering just how many people have moved on to other codecs for anime, and what they found to be better, as i want to try encoding with the best codec for anime now. xvid? divx5? ogg audio? also, how high are the odds of getting shit frames with the newer codecs? as i use antishit in nandub and its saved many encodes of bad frames.

[Koepi]

Shitframes were a special phenomenon of the DivX3 codec hack - and only of you constrained it too much.

So you won't have shitframes in xvid - and not in divx 5.

[diji1]

encoding in ogg is going to give you more space for video at the same quality as an equivalent mp3 ... so ogg is recommended from me regardless of video codec.

[avih]

Ogg is just a container name, like 'avi'. the audio format is called 'vorbis', and indeed, vorbis is considered better than other audio compression formats.

[diji1]

indeed ur right avih ... my mistake. :\ naming does seem all over the place for that format atm( as in people using incorrect terms as i just did ). we must ensure that we use the correct naming i think to reduce confusion generally ;)

aside from that ... "vorbis machine" just doesn't sound like "ogg machine" does it. hehe. ... wonder if it sounds as "scary", lol.

I don't see any reason for still use DivX 3.11. I had lot of problems with Aristocats and that codec, many bad and frozen frames.
I didn't have bad frames with DivX 5.

[Neo Neko]

Yeah there are enough good alternate codecs out there to make encoding to MSMPEG4/Divx3 less and less worth while. The freeze frames. The crap frames. The altered colors. The blatant MSMPEG4 errors. I have not been using Divx much myself anyways lately. Xvid is really getting good! Can't wait till Xiph gets theora going!

[atracus]

imho Realvideo 9. definitely.

[atx]

[RadicalEd]

I second that. Realvideo 9 is the best for low bitrate anime, and RealAudio 8 at 64 kbps is about equal to ogg at 96, and mp3 at 128 in my experience. The only drawback is that smil scripting is a lot harder than putting 2 audios and 1 subtitle into oggmux (then again.. subs never did work for me e.e). But with smil and Realvideo 9 you can get 2 audio streams in at 128 kbps total (or 88 if you're going real low, 44 kbps isnt bad but the compression is noticable). That makes for awesome 1cd rips.

Although I do use XviD and/or DivX 5 with vorbis every now and then because my 1 ghz athlon struggles with Realvideo 9 at 640x480 :(

I use DivX5/MP3 for all my encodings, anime or not anime.
But I must say that DivX3 is the best codec for anime, because it doesn't make mosquito noise (that noise around drawing lines). Though I don't know how to use NanDub, it's too complicated.
I tried using DivX3 in GKnot, but the files got too big, where DivX5 has reached the wished size exactly.

The mosquito noise around the lines is due to your quantizers being to high. At least in my experience. In Xvid Clamping down on the quantisers a bit and forcing a smaller file size have actually reduced the mosquito noise in many cases for me.

Even back with RealVideo 8 I was amazed at how there was absolutely no mosquito noise at all. I said this in some other post but I'd sure like to find a detailed description of Real's compression technology. I dunno what kind of quantizers it uses but it sure is different from common MPEG.

Oh, I found it.
Here (http://forum.doom9.org/showthread.php?s=&threadid=26598) you can see me babble about how Real is a lot different compared to MPEG if you feel so inclined.

I don't think they're doing anything radically different from MPEG traditions, they're just forcing post-processing to *always* be on, and having it affect reference frames during encoding, ala JVT:

- Encode frame with usual DCT/quantization
- Run post-processor over encoded frame to remove "mosquito noise"
- Use the post-processed frame as the reference frame for the next frame, so that we refer to a smooth, post-processed image (instead of the blocky image as in MPEG1/2/4)

It can do wonders for image quality, which is why the finalised MPEG4 video spec (which is what JVT is contributing to) will include it, as well as a whole heap of other nifty compression methods.

@ Neo Neko
I'm using a Max Quantizer of 8, which Quantizer are you using?
Encoding really hard to compress Anime like Dragon Ball Z, I must go over 0,3 bit/pixel to get rid of mosquito noise and that using GMC & Bid. Encoding, after having filtering the image with the TemporalSmoother/SmartSmoother Combo!! this is so weird!

@ RadicalEd
You're right about Real Video 8, I was amazed from the quality of a 2-pass encoded 300kbps video (it was 320x240 25fps), it looked so good for such a low bitrate, I mean amazing!
BUT! Real Video is a proprietary format, it can't be converted (well, not easily at least :D) and that's why I better use DivX with a higher bitrate.

[Kyo]

I have used XviD in lot of anime DVDs and the quality is great.
But i think that 3.11 has some type of preference to Anime :)

[Infophreak]

Theoretically DivX5 ought to be great for anime encoding because of GMC with all the pans and slides that are usually present in anime. DivX5's problem with edges however does detract from it. I guess we can just wait and hope that GMC will find it's way to XviD as well.

[DJ Bobo]

@ Infophreak
GMC is not that spectacular, the gain in bitrate is very minimal. Add to this that there still some problems when GMC is used. See here: http://forum.doom9.org/showthread.php?s=&threadid=27251
The really good setting is bidirectional encoding, all other stuff worth nothing.

Talking about mosquito noise: DivX3 may have less mosquito noise, but it's definitely there unless you put cpu quality full on, which is not possible, unless you have a really powerful machine (over 1GHz for hi res rips).
The same thing applies to DivX5: put quality to max and you won't see mosquito noise anymore.
This is what most people aren't aware of.

And a word about XviD: it's something for freaks only IMHO, the name is just crap, what would I say "I've done an XviD-Rip" definitely embarassing name! :o
And talking in terms of quality: XviD is at most just as good as DivX, so why bother. As said, in my opinion, XviD users are freaks, just to be different from others "hey I don't use DivX, I use XviD" it's as weird as it sounds.

[Neo Neko]

I don't use Xvid to use Xvid. I use Xvid cause I can set I and P and someday B frame quantizer values individually. I use it because of the better motion estimation. I use it because of the better size predictability. I use it because of the alternate curve compression. The custome quantizer matricies are interesting as well. I use it because it is opensource. I use it because I like what the coders are dooing with it. I use it because it is MPEG4 compliant. I use it because I like the results. I give people Xvid encoded content and don't tell them till they ask how I got it to look so good.

Oh and in case you did not already know read XVID in a mirror and you will. Personally i think it is an excelent name. It works on it's own and it is a fun play on it's origins.

[DJ Bobo]

@ Neo Neko
I already know that XviD is DivX in the other direction, and that's why I think that name is wierd ;)
And I tried XviD already and the results were almost like DivX. To be honest, I couldn't even tell where the difference.
And DivX5 is 100% predictable (I don't wanna even think about DivX4, it was like playing in a casino :D)
You may be right about the quantizer setting possibilities though, which aren't available for DivX5, unless one uses some special tools, that I don't wanna use. That point goes to you :D But as to save my word, I played with those things a bit, and their impact is not visible, unless one's really looking to see the difference on a given scene.

[Acaila]

To be honest, I couldn't even tell where the difference.And XviD doesn't even have DivX5's MPEG4 tools yet, need I say more?

[RadicalEd]

/me thinks DivX sounds pretty weird o.o
the sound of Xvid amuses me so shh u

and XviD isen't? w00t!


Yeah i'm a freak! I want the best possible quality! I want to tweak every possible value! :D

about RM-9.. Closed up pice of blurred shit! And its not even MPEG-4 compilant! :devil:

[RadicalEd]

What do you need to edit it for anyway buba? If you're archiving, what does closed have to do with anything. Owell, you can hate RealMedia for its format if you want, but my videos will look better than yours :P
