How to convert DivX/XviD with AC3 to a DVD with AC3 and subtitles

by burniso on October 25, 2004

There already many AVI to DVD guides around but this one is by far the most
complete and easy one. It wil explain in detail what you need to do to create
a DVD with AC3 sound and subtitles from a DivX/XviD file with AC3. You will
find VirtualDubMod, AC3Filter and VobSub in our downloads section, as well as TMPGEnc
which contains a 30 day trial of the MPEG2 encoder. Note that you can use whatever
encoder and authoring tool you want, we show the preperation process and then
how to use some popular tools, you can use your favourite programs, or see
the other guides of the sites for some other solutions!

Install AC3Filter. Then open VirtualDubMod and load the AVI file. If your rip is a 2 CD one, read
the next step about how to join them, if not then proceed to step

For a 2 CD rip first load the first AVI and then select File -> Append
segment and open the second file as well. This will open the second file
and put it straight at the end of the first one. Now you can edit the
files as if it was only one of them. Just to be sure that both files
are successfully loaded click the icon to go in the last frame and see
if the length is correct.

Now select Video -> Direct Stream Copy.

Time to extract (demux) the AC3 audio from our files. To do that go to
Streams -> Stream List.
You should see an AC3 audio stream. Click Demux to save it in the hard

Give it a name like sound.ac3 and save it in a temp folder in your hard
disk. It should not take more than 5-10 minutes. When it ends you will
be back in the Stream list window.

Now click the button named Disable (it’s the one that says Enable in this
picture). The audio stream should go grey and get lines all over it.
He are doing this as after we extracted the audio, we don’t need it in
the AVI file too. Now we are gonna save the AVI file with no sound. If
you have only one file you may want to skip this step and use the original
file, if not, the next step with merge the 2 CD files also, so you gotta
do it.

Finally you’ll need to save the video file. Go to File -> Save As. Select
the directory you want to save the file into, name it like video.avi
and make sure that Direct Stream Copy is selected. Then click Save and
wait for the proccess to finish.
It should not take more than 10-15 minutes. When it ends you should have
a video.avi video file and a sound.ac3 audio file.
Next step will be to configure the subtitles, so if you don’t want to add subtitles
you can proceed to step 9, where we are going to encode the video file.

There are actually not many things that need to be done with the subtitles.
You have to obtain subtitles either from ripping them for the original
DVD or by downloading off a subtitle site. Then install VobSub (find
it in the downloads section) and from the shortcuts it creates in the
start menu select DirectVobSub Configure. All you need to take care here
are the fonts and paths. Make sure you click the button with the name
of the font on (Arial is OK but you can use whatever you want) and set
the size to something bigger than the default, like 20 or 22. The other
options should be just fine as in the picture. Also in the Paths tab
make sure “.” is there. If it’s not add it using the add button. Then
click OK.
Now all you have to do is name the subtitles file or whatever
the original sub type was and put it in the same folder as the video
file. Now you should check whether the audio and the subs match. To do
that get BSPlayer (find it in the downloads section) and load the subtitles
and the ac3 audio file (using the Load Extermal Audio option that appears
if you right-click on the video while playing back).
Now if the subtitles are out of sync you need to try and fix them using
Subtitle Workshop, a great free tool. You can find it in the downloads
section too. You can also use it to join subtitles if they are in different
files. Please do not come in the forum and ask why some subtitle file
is out of sync, try to find one that works with your file or use Subtitle
Workshop to see if you can fix it by setting the start time and / or
changing the fps.
Now we are ready to encode our video to a MPEG2 file than will include
subtitles and then author to a DVD with AC3 audio! To do that, load TMPGEnc and click Next to go to the next page of the guide.


Here you need to select the type of the MPEG file you want to create. Select
DVD of course and then it’s type depending on the file you have (if it
is NTSC or PAL, 16:9 or 4:3). Select whatever you want about the audio,
we are not gonna use it anyway.

OK here click Browse and select the video file. In the Content of video
field select video for 29,97 fps movies and Film for 23,976 ones. Note
that this option appears for NTSC DVDs only. Leave the other options
as is, click Next and then Next again to go to the next screen that we
need to make setting to!

In the next screen we’re gonna have a look in the Expert settings. Locate
the expert button somewhere in the right top of the window and click
on it.
Now you gotta select what mode you’re gonna use. CBR is faster, but VBR
(2-pass) will create much better quality file. Note that it’s gonna take
twice the time CBR takes, so the choice is yours. Motion search precision
is OK at the default Motion estimate search (fast) option. Now click
Advanced tab.
Here select the right source aspect ratio depending on your source file.
In that case it’s 16:9 NTSC. In the Video arrange method you should use
Full screen (keep aspect ratio). The Inverse telecine option you see
selected below, should be selected only for NTSC Film movies, and that
it is enabled by default.
The settings we need to make here are done, click OK to go back in the
previous screen.

Here you need to set the file size to 99% of the disc. Be sure you select
384 as the audio bitrate, as we need to make sure that both the audio
and the video will fit in the disc after authoring. Then click Next.
In the next screen just leave all options blank and click OK to go back
in TMPGEnc’s main window.
Finally in this window select ES (Video only) and then click Start for
the encoding to begin. It’s a good idea to wait and see in the preview
window if the subtitles are displayed correctly. After encoding finishes
you should have an m2v file with MPEG2 video plus subtitles in it and
an AC3 audio file. Next comes the authoring, so load TMPGEnc DVD Author
and proceed to the next step.

In the first screen of TMPGEnc DVD Author select Create new project.
Select Add file in the next screen.
And open your video.m2v file.
It should look like that after you load the video file. So click Browse
and load the ac3 audio file as well.

Everything should be like that after you load both the files. Now you can
select Chapter cut edit to add some chapters. Then click OK.

The next steps of the TMPGEnc DVD Author are rather simple and you can
see them in detail in tthe authoring guide here.
After authoring finishes you just have to burn, and your DVD, containing
AC3 audio and subtitles is ready! To burn you can use TMPGEnc DVD Author’s
DVD burner or an external program like CopyToDVD.
