Full DVD Backup guide

This guide will teach you how to create a perfect backup of a DVD-9 retaining every asset present on the original disc. It's possible to remove audio or subtitle tracks and replace useless stuff like FBI logos by some blank video but in the end we're not going to change the basic structure of the DVD and thus risk the least amount of problems.

In this guide we're going to use four front-end tools that will make the whole process a lot easier: DoItFast4U (DIF4U), BatchCCEWS (BCCE), ScenAid and NuMenu4u (NM4U). DIF4U will rip and demultiplex VOB files for you. It'll launch NuMenu4u, which re-encodes large menu files. Then DIF4U will continue using the reduced menus, create DVD2AVI projects and AviSynth scripts to be imported into the MPEG-2 encoding program and it will correct any delays the audio files might have as compared to the video stream. ScenAid will then analyze the DIF4U output and create the proper Scenarist project for you and will control BatchCCEWS for encoding. Scenaid will also provide the correct handling of Angles and Chapter placement in the video streams. Finally BatchIfoupdate will update your .IFO files, and combine the remaining original files, the NuMenu4u files and the Scenarist reauthored files into one folder. If you have VIP status then Muxman can be used for authoring instead. This guide will cover authoring with Scenarist or Muxman, use of the Advanced features of these tools and also the specialist VIP options available.

You will need the following software for this guide:

BatchCCEWS and a suitable encoder (Rejig, CCE, Procoder, QuEnc and HC Encoder are all supported)

Sonic Scenarist or Muxman 0.15 (if you have VIP status)

Please Note: it is always recommended to use the latest versions of this software, which at the time of writing are:
DIF4U (1.4.7- public & 1.4.8 -VIP)
NuMenu4u 2.0.22

Step 1: Preparation

In this guide we're going to put the DVD-9 SPIDERMAN 2, R4 (DISC 1) having a total size of 7.5GB onto a single DVD-R disc. This edition of the movie contains 2 language tracks, 2 commentary tracks, multiple subtitle tracks and a lot of extras, including duplicate PGCs If that doesn't scare you then I suppose you either don't know what the heck I am talking about and may be better off learning the DVD-R basics first or you reauthor The Matrix for breakfast in which case you most likely have no use for this guide ;) This training day is going to take you very far into DVD-R land and you're going to see things you have never seen before. But if you stick to the path you should be getting where you want to go to.

VTS_01 is obviously the main movie VTS set as it's the largest one. In this guide I'm going to show how to transcode each video item, but in some cases you might prefer to only encode the main movie. CCE can give you good video quality using a bitrate of 2500 kbit/s or higher. If you add the bitrate of the audio tracks you're going to keep to that and multiply this by the length of the movie in seconds you have an approximation of the size of the main movie (add about 100-150MB for the muxing overhead to get a more realistic result). If you add the size of the extras (all VTSes besides VTS_01 in this case, and don't forget about VIDEO_TS.VOB) and you're still below the size of a DVD then you may not want to bother doing the extras as well.

The best way to begin is create an ISO image of the DVD and mount this as a virtual drive. That way we'll always have every file we need available right on our hard disk and won't have to insert the original DVD again. It also saves us from embarrassment of accidentally deleting a file you'd still need as all the files in the image are read only.

Step 2: Demultiplexing

Now we literally have to rip our movie to pieces. In less martial terms we're going to separate audio, video and subtitles and process them independently of each other.

Now let's get started for real. The first thing you'll have to do is select a working directory. This is the directory where all the demultiplexed files will be stored (alternatively you can create a new folder, right click on it in Explorer and select DoItFast4U into this directory).

Create folder for this VTS, if checked, will create a new folder and demux the currently selected VTS into this folder. It's a per VTS setting so you can decide to put multiple VTS sets into the same folder by un-checking this option for the VTS you'd like to go together (they'll be placed in your working directory). Note that if you followed the first time setup instructions above, this checkbox will be set already and you shouldn't have to touch it. HDD Demux would have to be used if you previously ripped the whole DVD to a directory on your hard disk (not suggested!) in which case you'd have to select the directory containing the ripped files as working directory. Then we have demux by VOB ID or Cell ID. The latter should never be necessary.

*Supplementary Information*

One of the biggest problems for a beginner is to determine whether a VTS needs to be processed at the PGC level or at the VOBID level. Fortunately DIF4U is pretty good at making this determination but it is good to know the details. Basically to demux at the PGC level, at least one PGC or a combination of PGCs must contain ALL the VOBIDs (without selecting a VOBID more than once). An example to help: A VTS has 4 PGCs and has 5 VOBIDs:

  • PGC1 uses VOBIDs 1,2,3,4 & 5. PGC2 uses VOBID 2, PGC3 uses VOBID 3 and PGC4 uses VOBID 5.
    In this case DIF4U will select only PGC1 to process, because, PGC2, 3 & 4 can all be made from PGC1.
  • PGC1 uses VOBIDs 1,2,3 & 5. PGC2 uses VOBID 2, PGC3 uses VOBID 3, PGC4 uses VOBID 4.
    In this case DIF4U will select PGC1 & PGC4, because PGCs 2 & 3 can be made from PGC1.
  • PGC1 uses VOBIDs 1,2 & 3. PGC2 uses VOBIDs 1,2,3 & 4. PGC3 uses VOBIDs 1,2,3 & 5. PGC4 uses VOBIDs 2,3,4 & 5.
    In this case no combination of PGCs uses all the VOBIDs without repeating at least 1 VOBID. If this were done by PGC we would encode unnecessarily, so DIF4U would select VOBID demux.

    The next thing we're going to look at is the mandatory section:

    (Virtual) DVD Drive is the drive letter of your mounted ISO image. Then you can select a bitrate to be used for the extras contained on the DVD (do not go above 2000 or below 1500 for reasonable quality). Minimum MB to demux allows you to not process VTS sets that are below a certain size (in this case if there were a VTS set smaller than 200 MB you wouldn't bother processing it as the possible space gain would be outweighed by the invested time).

    DIF4U will also give you a global overview of the disc, including available VTS sets, PGCs, their lengths, audio track IDs, number of subtitles, subtitle track IDs and aspect ratio.

    By default all VTS sets including all associated PGCs will be checked. If a VTS set were smaller than the threshold we set above (200MB in our case) it would be unchecked and hence not be processed at all.

    If a VTS has multiple PGCs it is always worth confirming what PGCs need processing or whether a VOBID demux is needed. Right click on a VTS will open that VTS in IfoEdit, which by default will show the PGC layout and which VOBIDs are used by each PGC. If you disagree with DIF4U then doublecheck! yourself, and then select/deselect the PGCs as needed or in the case of a VOBID demux being needed turn on Demux by Vob ID.

    From this point on all our settings apply to the currently selected VTS set, so come back to this selection and select the next VTS set when you're done configuring. Below I'll illustrate my setup for the main movie VTS set (VTS 01).

    The first thing to be done after selecting a VTS set is configure the audio options:

    As we were able to see in the previous screen shot, the main movie  contains 6 audio tracks, 0x80, 0x81, 0x82, 0x83, 0x84, and 0x85, those being 6ch English, 2ch English, 6ch Italian, 2ch Italian and two more 2ch English (the commentary tracks).

    Because the title is fairly large and we need all space available only the English audio is kept.

    Then let's also configure the subtitles:

    Here I once again only keep those languages I actually understand. Subs won't take much space on the final product, so it doesn't matter if you decide to keep them all. The reauthoring slows down considerable though when importing and muxing subs.

    Then we have the optional switches:

    The upper line deals with Subtitles. If your current VTS has angles then ensure that Angles is selected. Raw Subs is always unselected, but Subs should always be selected and if you are an NTSC user and your movie has Closed Captions (this is also shown in the VTS window - denoted by CC in the VTS name) then Captions should be selected also. The lower line is there to inform DIF4U what the video type is for the current VTS - assuming you know it. It is easier to let DIF4U determine this so make sure that AutoDetect NTSC Video Type is selected (the lower line will be greyed out), for NTSC and PAL users. (For PAL users further investigation will be needed. This is covered later).

    This is all you have to do for one VTS set. Now repeat this procedure for all other VTS sets present on the DVD. The last thing to configure is the number of passes for extras and the main movie:

    The lower your bitrate, the more passes can be useful, but going beyond 5 is definitely overkill. I'd say 3 / 4 will suffice in most cases, and in some you can even go one lower, but this really depends on the source and your quality requirements.

    Now that we have configured everything let's rock. Press the Do It! button and let DIF4U do it's thing.

    If you're using NM4U, it will be automatically started and all paths will be filled in:

    In addition, you'll see the available disc menus listed:

    In our initial setup of NM4U we chose English as our default language. So when NM4U started up it preselected just the English version of the Menu.

    While NM4U is processing, you can watch its progress in the Log:

    NM4U will completely reauthor the menus so don't be concerned that some encoding and reauthoring is happening. This is all automated. If you are a VIP user and have selected to Preview and Strip unwanted Video/Buttons then go here for a detailed stripping guide.

    Once NM4U completes, control will automatically be returned to DIF4U.

    If ReJig was selected as the encoder in DIF4U, Rejig will be started and all of the video streams encoded.

    Once DIF4U has finished, you can manually start ScenAid.

    Step 3: Encoding & Asset Processing with Scenaid

    Once Scenaid has been launched, we need to select the directory that DIF4U has demuxed all of our assets into. Following selection of this directory, ScenAid will then scan and process our files, and create our Scenarist Script File (.scp).

    If you had chosen to process your assets using Rejig in DIF4U, you can proceed directly to step 4.

    If you had chosen Generate script after scan (one-click run) then the encoding would be automated so you can proceed directly to step 4.

    Now that Scenaid has completed its' scan it will now present a detailed breakdown of each VTS. At this point we can decide if there are any VTSs that are wasted.

    Click on each VTS# in turn and then select each PGC in turn.

    Each will now show in the small preview window. If you decide that there is a VTS that isn't needed then unselect all the PGCs in that VTS. If there is a specific PGC that isn't wanted then deselect the PGC.

    Removing any VTSs/PGCs will cause the MAIN Bitrate to increase and force Scenaid to create a dummy asset in its place.

    This guide is intended to keep the structure of the disc intact, but, I have several discs where a VTS is just a black screen and is never used. Obviously there is no need to keep this so unselect it. Also I don't care for trailers of other movies so they are removed. Everything else is kept.

    When finished if you feel the MAIN Bitrate is too low then alter the Extras Bitrate to a lower figure and the MAIN Bitrate will increase.

    Pressing the 'Save' button in Scenaid will force Scenaid into generating our script file (.SCP if Scenarist is being used, .MXP if Muxman is being used). Scenaid will now open BatchCCEWS and load up all of the files to be encoded.

    BatchCCEWS will show you a list of files to be encoded:

    As you can see, the jobs have the following names: VTS__XY_AB, where XY is the VTS set number and AB is the PGC number. Behind the dot, I means interlaced and P means progressive. In case of Interlaced, there will also be either a -TFF or -BFF attached, representing the field order. Finally, you have the resolution of the source - either 4~3 for 4:3, and 16~9 for 16:9.

    Right now, all jobs are marked with a white dot. Once you start encoding (by pressing the triangle button pointing to the right - the same as a play button on your DVD player), the file currently being encoded is marked in light blue, and files that have been encoded are marked in green.

    You can use the buttons below the Jobs to remove (-) a job, or move them up and down using the triangles pointing up or down.

    The omega button can be used to reset a job to pending status (useful if a job has failed and you've corrected the failure case) and the last button can be used to clear out the job list. While encoding, the stop button (a red square) allows you to abort the encoding process at any time.

    If you are an NTSC user then you can start encoding immediately (If you set the option in Scenaid Start Encode on import, then this will be automatic.)

    If you are a PAL user then you must now decide which video files are Interlaced and which are Progressive and adjust the settings in BatchCCEWS accordingly or if you just what a more detailed explanation of the settings then read this guide.

    Step 4: Reauthoring

    Following encoding, Scenaid will then close BatchCCEWS and either:

    Now it's best to check out if your disc works. To do that use a software DVD player like PowerDVD, and check everything is correct.

    Step 6: Problems

    A problem that sometime occurs is that the wrong audio track is playing. If this should be the case, open the corresponding IFO file in IfoEdit, go to the VTS_PGCITI section and select the appropriate PGC.

    As you can see the audio stream status increases by increments of 256. If instead of the first stream the 2nd one is being played set Audio stream 1 status to 33024 (and Audio stream 2 status to 32768) and save the IFO again.

    Now press Update IFO.

    If you want to remove certain user prohibitions (as in not being able to change the audio track via the appropriate button on the remote while watching the movie), or strip out subtitle and audio channels that you have not included in the reauthored project. You can find all these steps here.

    Once this has been done you're basically ready for burning. I suggest you follow the guide by making use of an image file.
