If you want to add another subtitle language to your DVD, here is a guide to help you do it, using only freeware tools. Also in case you are not happy with the original subtitle positions or colors, you can use the same process to reposition them, or remap their colors.
· DVDshrink (release 3.2), to compress the DVD, and create a backup on your hard disk.
· Subtitle Workshop (optional), to convert subtitles to SubRip *.srt format.
· PgcDemux, to de-multiplex a DVD to separate movie (*.m2v), audio (*.ac3) and subtitle (*.sup) streams
· IfoEdit, to multiplex video, audio, and subtitles back together again to a DVD. Alternatively, use ReJig instead of IfoEdit – a bit slower and needs more intermediate hard disk space, but you won’t have to copy the subtitle colors in step 5.
· VobBlanker can optionally be used if you wish to keep the menus.
· DVD burning software
· At least 9Gb available on your hard disk.
The main steps are described here
a) Open disc (top left)
b) Enter re-author mode (top right): Drag everything that you want to keep, excluding the menus, from the right DVD browser window to the left window. Here, only the main movie is preserved. But, alternatively, you can also copy the extras to your re-authored DVD, and they will be included as additional chapters at the end of your movie.
Although DVD Shrink is very good in keeping the menus (use full disc backup in that case, and compress the extras manually), after adding the subtitles they won’t work anymore unless you go through some very elaborate steps as explained in optional step 7 below. The reason for this is that the corresponding IFO file, generated at the end of the process described here, doesn’t know anything about the menu structure. There are two other solutions that I didn’t try myself, that you might want to look into if you are really keen on preserving everything. The first is by searching for IfoUpdate, the other is by doing everything manually, as described here:
c) Select the compression tab, and deselect any audio and subtitles that you don’t need – deselect the audio because they cost a lot of space, deselect the subtitles so you don’t have to include them anymore later on.
d) Press backup DVD (top menu) and select where you want the output to go. Although DVD shrink includes an interface with Nero, allowing it to directly write your stuff to a DVD, you should deselect this option in the preferences, as we still need to add our new subtitle. Additionally, if you have to compress a lot (say to less than 80%), it is good to set the deep analysis mode (tab ‘Backup options’, ‘smooth’ interpolation), as it will lead to a better video quality.
While DVDshrink is creating a backup of my DVD, I download a subtitle and if it is not in SubRip or MicroDVD format (i.e. it doesn’t have the *.srt extension or *.sub format, convert it using subtitle workshop to SubRip format).
Further note that I first had some trouble to see special characters correctly (2b+d): I had to use the Central European font in this tool, but I also needed to change my general computer settings (Control panel/Regional settings/Advanced/Non-unicode language/ to Romanian).
· Press CTRL-X for express mode. It will allow you to load your subtitle file, the IFO file of the current DVD with the color palette (normally VTS_01_0.IFO), and an existing SUP file for synchronization purposes.
· Press CTRL-S to start generating your *.SUP file
Optionally, you can:
Figure 3. SubtitleCreator converts your subtitles to a *.sup stream, which can be multiplexed with the DVD's video and audio streams.
Note that the following two steps can also be done using Nik’s freeware tool, ReJig, which has almost identical interfaces, and has better support for NTSC movies: instead of step 4, select ReJig’s file mode, instead of step 5, select ReJig’s DVD Author mode. However, it is slower and produces large temporary files, so I normally prefer IfoEdit and VobEdit.
By this time, DVDshrink will probably be ready, and you have a set of IFO (InFOrmation), BUP (BackUP copies of IFO), and VOB (Video OBject) files on your hard disk. The largest IFO contains the movie.
1. Start PgcDemux, and open the (largest) IFO movie file.
2. Select the output folder.
3. Select ‘Demux video stream’
4. Deselect ‘Create logfile’
5. Press ‘Process’
Note: Older documentation contains an example using VobEdit. However, this program is no longer supported, it seems, and it sometimes gave errors in IfoEdit (too many framedrops), which I didn’t get anymore after I switched to this program. Another advantage is that it automatically creates the CellTimes.txt, which contains the start frames of each chapter.
Tip: Before I run PgcDemux, I execute a small script (setdvd.bat, stored in my Windows directory, so I can always run it), which contains the following three lines, and which I run from the DVDshrink output directory:
copy VTS_01_0.IFO AUDIO_TS
In the AUDIO_TS folder, the de-multiplexed (step 4: *.m2v, *.ac3, and *.sup) files go (see selection in Figure 4, step 2).
In the VIDEO_TS folder, we will
put the newly multiplexed movie.
This has the advantage that it has the same structure as a DVD, which is needed by some software players, like WinDVD, when playing from a file.
Start IfoEdit and select menu item DVD Author/Author new DVD (this has to be the first thing that you do in IfoEdit, else this item is not available).
Note: If you don’t have much free space on your HD, you can now delete the original VOB files used in step 4 (don’t delete the IFO file with the same name).
The final step it to copy the subtitle colors from the original IFO to the new IFO (see Figure 6): as this often creates problems, I have indicated the steps separately. In case you use ReJig, you don’t have to do this anymore, as you already selected the IFO in step 5 above.
Using a DVD player (e.g. VideoLAN) that can play from the hard disk, you can quickly inspect whether the DVD was authored correctly. If you are satisfied with the new subtitles, burn the files to a DVD (in the VIDEO_TS folder) and enjoy!
7. Optionally, add the menus
Finally, if you have decided to keep the menus in step 1, you need to do one last step, which VobBlanker (thanks to a tip from ConNS) makes very easy.
