Cinefórum-Clásico

La verdad es que cuanto más lees más confuso se vuelve esto del ripeo.
Yo tenía entendido que para hacer el d2v, en el DGIndex tenías que usar el Honor Pulldown flags, y no el Force Film.
A ver si algún entendido aclara un poco la cuestión.

Mercedes, con tu experiencia en ripeo XviD tienes muchísimo camino ya andado. Una vez que se dominan dos o tres aspectos básicos, ripear en MKV es muchísimo más fácil que hacerlo en XviD. Ni siquiera necesitas un software para hacerlo, con la línea de comando alcanza. Y el resultado es muy superior, porque te permite arribar a un archivo que tiene prácticamente la misma calidad del DVD de origen.

Mercedes, yo no puedo comparar con Divx (avi) porqué nunca he ripeado en ese formato.
Y en este poco. Todavía estoy aprendiendo y últimamente no he tenido tiempo. Al principio me sentía más un autómata que otra cosa. Ahora le voy pillando el tranquillo.
Personalmente me está gustando, el único problema que tengo es el de no tener hardware a la altura del codec , que es muy exigente y se me chupa horas y horas y ho..

Cuando estés con tiempo y ánimo te apareces por aquí y nos echamos una mano mutua, entre novatos (anda, que calificar de novata a una de las reinas de la web, ya me vale)

Un abrazo fuerte

Hola,

Me ha escrito este hombre tomándome por otro, ya que mi primer rip tiene tres meses y (como diría mi abuelo, buena gente pero bruto el hombre) “soy más malo que un bocao en la picha” y no paso del sota, caballo, rey.

Debe de haberme confundido con Monsieur Lange.

La cuestión es que quiere ayuda para ripear en mkv e igual alguno, si le dais al inglés con soltura (y al chino), le puede dar una mano. Copio aquí su mensaje (con su consentimiento).

Un saludo

I have follow the instructions on the net and do some DVDRip myself, but I just wonder if there is some more other ways to improve the image quality as much as possible to the original source (such as DVD, etc)? I have wrote a note in Chinese about my ripping process, wishing you could have checked if I have anything wrong (guess you may understand what I have done by seeing my screen shot), the address: http://www.douban.com/note/261815670/

I'm from China and was not familiar with this Spanish forum, but knowing that there are many masters here, I wish my ripping ability could improved. I have looked through doom9 but didn't get much about image quality improving or filter. Now I only know "--sar" is to control the resolution and crf to control the quality, nothing more. I make anamorphic rips and keep the crf always 19.0, knowing that there are more tips in makeing DVDRips, I wish could get your help.

Sincerely, Alan He.

I'm not really a good ripper, and also my English it´s quite poor. If you want, I could open a topic with your request. Perhaps one of "kings of the rip" that use to collaborate in this forum could help you.

Ok? Cheers.

Sincerely.

Actually I didn't do much on avs file. Only cropping and I haven't try any filter.

As for "--preset", is there a big difference between "slow" and "veryslow"? The loss in picture quality or anything else? I have just do a rip using the "slow" preset and is afraid of making any mistakes.

I have also noticed that, in some of the black-and-white pictures rip, rippers use this in command line: --no-chroma-me. What does it mean? Just to keep the picture in black-and-white and not to have color deviation? And how could I judge when should I use this or not?

As for the "--sar", could I use ARS Calculator to calculate out the sar number? (I firstly use GKnot to crop and take a note of the resolution after cropping and the aspect ratio, and then I put this number into the ARS Calculator to get the sar number. So this is different when deal with different DVD because cropping is different.) According to someone, this will work fine. I have follow the rules as following but in some situation it doesn't give a good result.

Non-ITU PAR Table
PAL NTSC
FullScreen 16/15 8/9
WideScreen 64/45 32/27

And I wrote the command line like

Any improvement?

Hi Alan,

First, welcome to Cinefórum-Clásico! Second, I'm afraid I'm not the "king" mentioned by Bunker; I'm just a guy who learnt a couple of things from some wizz kids. If you want to contact some more experienced rippers than me you should try Dardo or Roisiano (not sure if they can communicate in English though).

Just a few comments on you notes:

xuguang_he escribió: As for "--preset", is there a big difference between "slow" and "veryslow"? The loss in picture quality or anything else?

Yes, if you're aiming for quality, there's a big difference. Preset veryslow is far more efficient to get the most of the encoding process.

Yes, --no-chroma-me (or other similar presets) is just to keep the picture in pure B&W with no color deviation. And you don't have to judge it at all: if you are about to rip an entirely B&W film, just use it. You only need to be completely sure that the original film was shot in B&W and doesn't have any color or tinted scenes on it.

xuguang_he escribió:As for the "--sar", could I use ARS Calculator to calculate out the sar number?

You could, but you better don't In all my knowledge, the best way to get the best SAR calculation is using your eyes. You just need to copy some code on notepad and save it as *.avs file (you must edit all paths, of course). I'm quoting elguaxo:

elguaxo escribió:We'll save the script as my.movie.avs. It looks for example like this one:

Código: Seleccionar todo

DGDecode_mpeg2source("I:\VTS_01_1.demuxed.d2v")

crop( 52, 14, -52, -14)

From DGIndex's report we are going to see if the DVD is PAL/NTSC, Fullscreen/Widescreen. Remember:

720x576 = PAL
720x480 = NTSC

4:3 = Fullscreen
16:9 = Widescreen

We'll save this script below as SAR.avs under the same folder of my.movie.avs. We are going to edit format and wide according to the data reported by DGIndex.

Let's open SAR.avs in VDM. Don't mind the black border's you'll see now, just focus on the AR. Look at many many screens to decide if it's ITU or not. The third line says x264 --sar and a number, for example 40:33. Write it down. That's the Pixel Aspect Ratio aka SAR (Sample Aspect Ratio).

Código: Seleccionar todo

avsfile = "my.movie.avs"  # Encoding script
format  = 1             # 1=NTSC, 0=PAL
wide    = 1             # 1=Widescreen 16:9, 0=Full screen 4:3
#########################
ITU     = (format==1?10:12)/11.0*(wide==1?4.0/3:1)
SARs    = """"12:11","16:11","10:11","40:33","16:15","64:45","8:9","32:27""""
ITUprof = "SDB "+(wide==1?"ANAMORPHIC ":"")+(format==1?"NTSC":"PAL")
i=import(avsfile).converttorgb
i
ab = round(height*(sqrt(45.0/44)-1))
a = spline36resize(round(width*ITU),height)
a = a.addborders(0,floor(ab/2.0),0,ceil(ab/2.0))
bb = width(a)-round(width*ITU/sqrt(45.0/44))
b = spline36resize(round(width*ITU/sqrt(45.0/44)),height+ab)
b = b.addborders(floor(bb/2.0),0,ceil(bb/2.0),0)
interleave(a,b)
scriptclip("""subtitle("Playback Resolution: "+\
string(round(width(i)*ITU*pow(44.0/45,current_frame%2)))+"x"+string(height(i))+\
"\nMeGUI Profile: "+ITUprof+(current_frame%2==1?" NON-ITU":"")+\
"\nx264 --sar "+eval("select(2*format+wide+current_frame%2*4,"+SARs+")"),lsp=0)""")

Regarding filters, best rippers usually doesn't like filters (mostly). Generally speaking, we're not interested in "improving" the source. Our aim is to get the most of the DVD in order to produce the most "transparent" rip that we can.

Best regards!

Thanks! I really don't know what I would have done without your help.
