How to make DVDRip

  • 1. This is not a “guide for professionals”, but tips on how to make DVDrip fast with real DVD quality. To my regret, the "professionals" always spoil the quality.
  • 2. This is not an object for criticism. I was criticized a lot and fruitfully, but none of the critics could make DVDripes better than mine
  • 3. No one is obliged to do as I recommend - rippers can have good reasons for getting worse results while increasing costs.
  • 4. The method is applicable to the "correct" DVD - these include most of the PAL discs and the minority of NTCS discs. My recommendations in general do not refer to "wrong" disks.
    • What we need to create a good DVDRip:

      Virtual Dub MPEG2 Rus ( http://www.pctuner.ru/page-al-virtualdub.html A selection of plug-ins, instructions, localization, and many other interesting things ... The 64-bit version of the program is also available, it is optimized for AMD processors Athlon 64, AMD Athlon FX, AMD Opteron, and Intel Xeon EM64T. To run this version, you must have a 64-bit version of Windows installed. In the normal version, even if you have the appropriate processor, the program cannot be started.)

      DVDDecriptor

      Ripping process

      1. Insert the disc into the DVD drive. We start the DVDDecriptor program and all the VOB files of the movie are copied into one VOB file on the hard disk (for this the corresponding tick is set in DVDDecriptor). It is more convenient to work with one file.

      2. The resulting VOB file opens in VirtualDub. Several frames are scrolling - if a “comb” is visible at the edges of moving objects, then the disk is interlaced, and you need to deal with it differently.

      If the picture is clear everywhere (and basically this is the case, if the DVD is normal, and not 10 films on 2 sides), then we continue.

      Select the filter resize (Video-> Filters-> Add). ALL Pal-disks have a picture elongated vertically, and NTCS - horizontally, therefore it is recommended to change the vertical size. The size needs to be changed "by eye" so that the number is a multiple of 16. Choose an approximation of bicubic 0.75

      It is not recommended to change the horizontal size (unless the black fields on the sides are removed).

      After selecting the size in the same filter, all black fields should be cut off - if there are any. Well and accordingly trimmed to correct the size of the frame at the output. If the fields are left, then a very large bitrate will be required for encoding boundaries and the movie itself will look much worse. In general, we looked at the original dimensions of the DVD and put the same dimensions in the RESIZE filter + Precise Bicubic interpolation (A = -0.75)

      Select codec (Video-> Compression). It is recommended to choose DivX, which is either installed separately or is included in the K-Lite codec pack. Other codecs - a reason for future curses addressed to you by your rip consumers

      Click the Configure button and set the encoding parameters. The coding type is Fast (low quality but fast), and Multipass-1st pass (nothing is actually encoded, but it is calculated how to code each frame better). How to choose a bitrate - a little lower.

      OK, OK, then File-> Save as avi -> and write the file name.

      Check the box "don't run this job now ..." below and click Save.

      Nothing happens, and rightly so - the process is queued.

      Go to Video-> Compression-> Configure again and choose the Slow and Multipass-Nth Pass coding (coding slowly and very well).

      Again File-> Save as avi -> "don't run this job now ..." - and write the file name, you can do the same thing, but you can and more. The other is better if the process starts at night and you don’t want to get up in the middle of the night and say "Yes, you can overwrite the existing file." Well, of course, if you have enough disk space ...

      After that, go to the menu File-> Job Control, select the first job in the list and shove into the Start button.

      After that, you can go to sleep (and you can sit and watch the progress bar move slowly, showing the percentages of the signatures).

      In the morning, a decent rip is ready for preliminary (or final) yuzanya.

      In general, on my PIV 940 2x3.2GHz, a two-hour rip in two passes takes about two hours ... so if you have a place, you can put two or three films on a rip for the night.

      BITRATE SELECTION

      It depends on the right choice whether you just get a rip "no worse than that of professionals" or really rip, not inferior to a DVD.

      For the DivX codec, in general, the heuristic rule "1K per square" works. The coding is made by 16x16 pixels and, therefore, for a kin with a size of 720x360, in general, it is worth choosing a bitrate (720/16) x (368/16) = 45 x 23 = 1035. Approximately.

      If the film is not replete with quick scenes, it is possible to reduce it to 900 (the contrast will decrease a little), which is often enough for a “single disc” rip with mp3 sound. For XviD, the bitrate is needed at least twice as large ... so I do not recommend it.

      For the narrow-screen 720x544 film, the bitrate of 1530 is already needed ... but in principle, as practice shows, 1250 is enough (iron DVD players with DivX support start sticking above).

      But in any case, after choosing the bitrate, you just need to cut a piece of the movie in VirtualDub for a couple of minutes, spend 10 minutes on two epaulets of this piece and see the result ...

      This is a theory, but in practice I started to do it differently: There is a small calculator on the bottom right of the DivX codec settings window. We press there, set the duration of the film, the existing bitrate of the sound track, the desired rip size, which we would like to receive, click OK and voila: we have such a bitrate that will fit the file size to the desired one. Naturally, bears choose a larger size than 700 MB, and, for example, 1400 MB - so the quality is better.

      Result

      After two runs in VirtualDub, you get a movie, usually with AC3 sound. Which six-track and places eats dofiga. And most often the four tracks are just "empty" - most of the films were still shot with stereo sound (if not mono).

      If the file size does not play an important role, then the movie is coherent to use. If you really need to reduce the file, then the sound should be changed.

      The easiest way is to launch a sound editor like CoolEdit (where to get it - I have no idea), select the option File-> Extract Audio from Video in it and point to a freshly prepared movie. The editor rips out the stereo variant from the AC3 sound. After that, “ripped out sound” can be saved as mp3 Fraunhofer CBR (with a constant bit rate - it will be easier to cut the file if necessary) or VBR - if you need to make the movie as “packed” as possible, and then “sew” a new sound instead of the old program NanDub (an old without "maintenance", but VirtualDubMod works much faster and is less buggy with this operation).

      That's it, the movie is ready.

      Right and wrong DVDs

      The correct DVDs contain a "progressive" picture (these are the vast majority of DVDs - almost all PAL and many NTSC) and, most importantly, the frame rate (framerate) is the same in the disc header and in the VOB file. This is for all PAL and about a third of NTCS disks.

      The picture affects the "appearance". And the coincidence of the frame rate is to synchronize the sound.

      Therefore, if DVD2AVI says that the frame rate is Kin is 29.970, and VirtualDub on File-> File Information states that the frame rate is 23.976, then the DVD is "wrong", and if you do, as it is written, then the sound with the picture will almost certainly diverge. And you should not try ... How to pre-test the NTCS discs, I don’t know ... according to statistics, the sound does not differ from the picture on 20% of merikish DVDs ...

      I have not had any differences on European ones so far.
      Well, merikansky disks rip in a different way, even if the mericans rip them.

      Everything.

      There is a fucking cloud of other technologies and rip programs that are "not worse." I personally like what I described above with sufficient simplicity and high quality of the resulting product - if the “raw materials” are at the level.

      Total:

      If you do not understand anything of the above, then I will break down the whole process, and follow it ...

      • 1) Insert the DVD into the drive tray, close the drive.
      • 2) Run the program DVDDecripter, in the options we are looking for a tick like "split DVD" (in different versions in different ways), start.
      • 3) Having received one VOB file on the hard disk, open it in VirtualDub MPEG2
      • 4) Video -> Filter -> Add -> Resize. We put the original dimensions of the vertical and horizontal (the same as in the original DVD). If it is necessary to cut off the black stripes, let's say, at the top and bottom, we cut it by the eye, but so that the height is a multiple of 16. Filter mode - Precise Bicubic (A = -0.75). We immediately press the "preview" button, if everything suits you - go ahead.
      • 5) Select the codec to compress. Video -> compression -> DivX Codec -> edit. Here we select Rate control mode = Multipass, 1st pass, a little higher we move the slider to the highest speed (but the lowest quality). OK -> OK -> File -> Save as AVI ... -> Enter the name -> Don't run this job (in general, add to the queue).
      • 6) Again we go to the menu: Video -> Compression -> DivX Codec -> Change. Here we select Rate control mode = Multipass, Nth pass. Move the slider to the end, we want good quality. We press right there on the calculator (small in the DivX settings window), put the exact duration of the movie at the top, set 1400Mb in the "file size" field (after all, and the quality will be better than in the 700-meter file, you should agree) In the "Audio bitrate" field, you should put the audio bitrate that has the original video file from your DVD (you can watch it by opening the DVD in Media Player Classic and viewing the video properties). We do all this because the bitrate will be substituted according to the specified and desired file size, that is, the size to the sound will be reserved. Click Accept -> OK -> OK.
      • 7) File -> Save as AVI ... -> Enter the name for the future rip (different from the previous name, for example "Super Rip by Vasya Pupkin"), tick the "Don't run this job now" and click OK.
      • 8) Click F4, or File -> Job control, select Job1 and Start in the list and go to bed.
      • 9) Morning, we don’t go to work, but we watch and marvel at our rip = = -0

      How to cut a 1,400 MB movie into 700 MB parts so that you can burn it to regular blanks

      1) We only need the VirtualDubMod program.

      2) Open the video file (I will open the film "The Island", because I like it, and you are any other)

      3) Allocation of the beginning of the 700-meter piece

      We need to select the first half of the file and save it, but save so that it weighs 700 MB to do this, put the slider at the beginning of the frame and click on the arrow highlighted in red (by clicking, we just note where the beginning of that piece is, which we will save, we will note the end a little later).

      4) Isolation of the end of the 700-meter piece

      The beginning of the piece we needed was noted, now we must mark the end. It will be somewhere in the center of all frames of the film (logically it turns out), for greater transparency we drag the slider to the right side and at the same time watch the program status bar, this is where we look at what size we have from the beginning of the movie to the location where the slider is located. Having reached the figure of 700 MB (not necessarily accurate, only approximately), we stop:

      5) Alignment of size

      In order to equate megabytes as close as possible to 700, press the keyframing button on the keyframe (smaller or larger, depending on what size the program shows you). By virtue of my strabismus, I got 700 MB, namely, 704.96 MB, so I have to go through the key frames to the left until I get a number like 700.xx, or 699, xx (which, in principle, not critical, but normal because it is a production error):

      6) Select the end of the 700-meter piece

      Seeing your approximate 700 MB (+/- 0.5 MB), click the button to designate the end of the selection, as in the picture:

      7) Saving

      Everything. Now, we essentially chose a TRUE 700MB from the source file. business for small - keep our selection:

      8) Be sure to select Direct Stream Copy in the save dialog (no need to encode, just direct streaming), save the first part ...

      Attached Image

      With the second piece, I think everything is clear, because the procedure is essentially the same, we only put the beginning of the selection in the place where the end of the first selection was marked, that is, without even moving the slider, simply press the corresponding button to indicate ...

      In the end, I received two files:

      Island.CD1.700Mb.avi = 702Mb (not scary, the SD will be recorded exactly as 700mb) <

      Island.CD1.700Mb.avi = 700Mb

      Good luck in ripps!
