encoding anime

[MigliO]

hi all!!!
I'm trying to encode Akira on 2cd with ac3.
I looking for the good settings.

could anyone give me some hints?
I've tried with th usual setting I use for real movies but the quality is not good.. the contour are not well defined.. the colors are not uniform...

tnx a lot!

What do you mean by colors not uniform!? You gotta encode in quality based 100% and see if it gets better. If it doesn't these are the limits of the codec!

If you have the US-DVD, your video is already highly filtered (THX digitally remastered).
So you won't need any special filter. May be TemporalSmoother(1) but not more.

For 2-pass encoding, lower the max quantizer to 8.

[MigliO]

this is what I mean...

[MigliO]

wait for the attach... :rolleyes:

Anime encodes usually need a lot more bits than normal movies. Try increasing your bitrate and see if Klaus Post's high quality smoother filter helps the picture. I find it makes the picture clearer. Get it here: http://sauron.mordor.net/dgraft/hiq/smoothhiq.html When encoding anime, I find that I have to lower the resolution or increase the bitrate by 50% to remove all the artifacts onscreen. Varies with the source though.

Anime get that ringing effect easily. A little temporal smoother and soft bicubic or neutral bicubic resizing usually clear it up nicely. Otherwise there's always post-processing if you have the horsepower (setting 5 or 6 is needed to de-ring).

[DJ Bobo]

You have also to check "Motion Compensation" & "Bidirectional Encoding", this will give you 25% better quality.
That means if you encode @1000kbps, it is as if you encode @1330kbps with the normal DivX5 version.

As proposed from pnl, use Smart Smoother. I personally use 3/30 for my TV captures, and that gives 20% better quality. But if you have the THX version, I don't think this filter will bring much.

And as Acaila says, for playback set Post processing to MAX.

And encode in a resolution of 512x288 (if you have the US version, don't forget to IVTC the movie to get 23,976fps and get once again 20% better quality)

[MigliO]

I have obtained the iimage you see with divx5, using neutral bicubic, gmc, bframes, at a 1200kbps..
the postproc was set to 3
bosting the postprocessing to 6 (I have the horsepower... :D ) clear it up a little...

Now I'm trying the 3cd way..
1600kbps, bframes, GMc..
Maybe a second audio track will fit...

btw... what about the second audio track? I mux it with ndub or it's better to put it as a separate file?

[DJ Bobo]

3 CD is crazy!
Lower your resolution if you wanna a clean picture with 2 CDs!

[MigliO]

why crazy?
the movie is 2hour long...
the res is 704Xxxx
at 1600kbps is 1.4Gb without tha audio (ac3 of course...) with 2 audio, the launcer and the player 3 cd is perfect...
:cool:

[DJ Bobo]

704x... is too much for 2 CD Rip! go for 512x288 and you'll get the nice picture you want!

3 CD Rip is crazy because 3 CDs is simply too much! 2 CDs are maximum for every rip! people making more than that are incompetent!

Don't try to be cool, be realistic!

[Deptmaster]

Wow! that is pretty ringy for 2 CDs.
Check the quality of the dvd picture.

Use TMPGEnc to check the fields are in the right order, and use AVIsynth with Decomb to do an IVTC

LoadPlugin("path\MPEG2DEC.dll")
LoadPlugin("path\decomb.dll")
mpeg2source("path\project file.d2v")
Telecide(Guide=1,Gthresh=50,Threshold=30,Chroma=true)
Decimate(5)
FieldDeinterlace
#BicubicResize(width,height,0,0.5)
#crop(left,top,width,height)
#trim(start frame,end frame)

Use Vdub to encode and it still looks bad consider lowering the resolution to 640x?.

I just finished Ninja Scroll (88min @ 620mb) with these settings and resized to 640X430 and the video looks great!

[DJ Bobo]

what the hell is 640x430?! if your movie is 16:9 -> 640x352!

[Deptmaster]

Sorry I ment 640X432. At 720X480 the picture from the dvd is not skewed at all.

crop(9,5,704,475)
BicubicResize(640,432,0,0.5)

These are the setting i used, I like to get rid of the ugly sides that show up on many dvds and the black bars on the the top and bottom. I use Gordian Knot to figure my resize numbers when i do my compressibilty check and i keep my dimmension factors of 16 and use cropping to reduce the aspect error. Here the aspect error is 0 but .1% isn't bad either.

[Zarxrax]

I've encoded Akira before so I know all about what a pain it can be. I'm afraid the problem is that the picture actually looks like that in the DVD. You need some heavy filtering to clear it up.

If I understand the help file correctly, it's useless to put fielddeinterlace after the telecide, since it's already included in the telecide process (unless you set post=false).

[Deptmaster]

FieldDeinterlace is good at catching the bad frames that make it through telecide and as i understand, it doesnt touch the progressive images. I can tell you from experience that its not useless.
