HOW TO CONVERT PAL DVDâ€™s to NTSC and VICE VERSA
Most countries in the world use the PAL video standard which
has a frame rate of 25 frames per second (fps). The US, Canada and Japan use NTSC which has a rate of 29.97 fps. Most DVDâ€™s are encoded from videotape with
a rate of 24 fps and are interlaced. The MPEG streams on the DVD contain
instructions regarding how to treat the video information for display depending
upon the type of DVD player. For example, to play a stream in PAL format, each
frame of the video is shown twice, video and audio data is interlaced and both
audio and video are â€œspeeded upâ€ by 4%. The audio then becomes slightly sharp
from its original recording, The data can be displayed non interlaced
(progressive scan) for component (RGB) video and on computer monitors.
Many DVD players are supposed to be able to play both types
of video formats. You could test this with a DVD that has been copied with removal
of region codes. Perhaps the manual from your DVD player contains instructions
as to how to view both systems from the menu control. If your player gives a
message â€œnot NTSCâ€ or â€œnot PALâ€ if probably wonâ€™t work. With the message â€œwrong
region codeâ€ when an NTSC or PAL disc is inserted, try a copied disc as
There are no doubt PAL DVDâ€™s in countries favoring NTSC and
vice versa. Those who visit other countries and purchase DVDâ€™s there may be
surprised when the title cannot be watched when returning home. You can
purchase â€œRegion FREEâ€ DVD players from a variety of sources. These have the
region checking disabled and chipsets that will display all types of media. I
purchased one of these and it did work but with significant vertical columnar
artifacts which could not be removed. These devices can be very expensive and
where is the warranty for a hacked device? They are not necessary for viewing
DVDâ€™s on a computer when region codes are disabled. Newer elaborate copy
protections do not affect playback on a computer, either, since you are not
copying to the hard drive, just decoding the VOBâ€™s with software. With four DVD
players in the house, it seemed to me to be much simpler to convert the
purchased DVDâ€™s with PAL format to NTSC and watch the copies.
For this guide you may need some of the following software:
2. Nero Vision
3. Intervideo DVD Creator 3
- COPY THE DVD TO THE HARD-DRIVE
The steps below assume your DVD has been copied to your
hard-drive and is unencrypted/unprotected.
Create a new folder in Windows Explorer
(File>New>Folder) in which to place the contents of the
2.NTSC to PAL CONVERSION
Your DVD consists of one or two main titles (movies) and
several smaller title sets. Insert a DVD and
in Windows Explorer, right click on your DVD drive and you
will see folder called VIDEO_TS. Open it
and you will see a list of files like this:
The movie is the title set VTS_03_1.VOB through VTS_03_7.VOB
. VTS_03_0.VOB is the menu for that
title set and VTS_03_0.IFO is the information file that
controls playback when it is read by a program. Each VOB is roughly
30 minutes long for a one Gigabyte file on the DVD.
The simplest way to convert from NTSC to PAL is called the
patch method and uses IFOEDIT which is free.
It is the readerâ€™s responsibility to transfer the DVD to the
hard drive in a folder that has been created by the reader of this article.
Now open IFOEDIT and navigate to the VIDEO_TS.IFO file in
the folder that you have created. Double click on this file.
In the lower pane of IFOEDIT you will see the letters NTSC
several times( Figure 2):
Each time that you see NTSC, double click on its line to
edit that line. You will see the following:
Change the standard to PAL and the resolution to 704 x 480.
You should choose an aspect ratio that follows what is present
on the NTSC DVDâ€”usually 4:3 or 16:9 which is letterbox. You
can read this directly from IFOEDITâ€™s panel. on the same line
as NTSC. If you do not specify a ratio, the DVD will be
Check Automatic Letterboxed for Static. For a 4:3 movie,
you can leave the STATIC box unchecked. Everything else can be left
alone. Now click SAVE. SCROLL DOWN in the lower pane to the
next line containing NTSC and do the same . Change every
line in this manner and SAVE. Your changes are not
reflected until you close and restart IFOEDIT.
Open the VTS_01_0.IFO file. Find every reference to NTSC in
the lower pane of IFOEDIT, make the appropriate changes
(edit this line) and SAVE. Open every IFO file on the ripped
DVD, make these changes and SAVE. Close IFOEDIT and restart it,
opening each IFO files and looking in the lower pane to
confirm that only PAL Video files are present. Now you can play the movie
in this folder in IFOEDIT or any DVD player to confirm that
all works well. To open a DVD folder based upon the VIDEO_TS.IFO
file, right click on this â€œmaster fileâ€ in Windows Explorer
and choose â€œOpen With.â€ After 30 seconds you will see a list of programs.
Most likely IFOEdit.exe is not one of them. Select â€œChoose
Programâ€ and you will see a list of programs. If IFOEdit is not there,
choose â€œOther or Browseâ€ and navigate to the location of
IFOEdit.. You can do the same for any other player
(Example: Program Files>Intervideo>DVD7>WinDVD.exe)
.The next time you right click an IFO file, the player will be available.
If playback is jerky or distorted, then verify that all of
the NTSC video parameters have been modified as described above.
This exercise instructs your software player or set top DVD
player to modify its treatment of the 24 fps files on the DVD to the
PAL standard. Now you can burn the new folder that you have
created onto a blank DVD. In the case of this example DVD,
shrinking will be necessary due to the large overall DVD
size in Figure 1.There are various ways and numerous programs which
will accomplish this. The commercial program Intervideo
DVDCopy will do this by opening the location of the video files.
You should have lots of free space on your hard drives(s)
to accommodate the temporary files created by the programs folders.
3. PAL to NTSC CONVERSION
Preparing for the Conversion process:
The Windows Explorer listing shown below in Figure 4 is for
a DVD with two identical titlesâ€”one with a 16:9 ratio and the other standard
When you open the DVD on your hard drive in IFOEdit (open
VIDEO_TS.IFO) look to the lower pane and you
will see the language information. As an alternative, you
can just watch the move and look for more than one language
in your viewing software such as WinDVD.
If more than one language is present you need to remove all
but the one that you want to keep. This is
because Nero may get confused and encode the undesired
language into the solitary AC-3 file it creates.
Also look in IFO for a DTS audio track although these are
If there is one, you need to eliminate DTS.
Create another new folder on your hard drive. In IFOEdit
open the VIDEO_TS folder of the DVD on your
hard drive and look for the IFO file for the main movie (see
above to locate the main movie). Click the VOB
Extras button. Your Destination directory should be the new
folder that you have created.
Use the settings below in Figure 5a and hit OK. In the next
step is that you will have the option to remove
languages and DTS audio by unchecking the boxes in the
dialogue box (not shown). Hit OK and IFOEDit will
take fifteen to twenty minutes to create a new DVD and DVD
structure (movie only) and new IFO files
In reality, only one language and no DTS is present in the
great majority of cases.
Use the new folder you have created (if it was necessary to
create it) for the next step.
USING NERO VISION
Nero Vision 4.7 is part of the Nero Suite Version 7.2 and
following. If you have a serial number for Nero 7.0, you can
download the current version which contains the new version
of Nero Vision and update for free. The file size is substantial.
Nero Vision has the ability import video files of all sorts
and convert them to NTSC or PAL DVD format including directly
VOBâ€™s from a DVD drive if AnyDVD is installed. Importation
of videos from the hard disc is always possible. They can be
VOBâ€™s, mpegs, or even AVI files.
From the Start Menu> All Programs> Nero 7 Ultra
Edition>Photo and Video> Nero Vision
At the bottom of the next page, you will see a button that
Click it to configure Nero Vision. The only thing that you
should need to verify is that fact that there is plenty of space
(folders tab) to accommodate the temporary files on your
hard drive or external hard drive. . Nero Vision places Imported
Videos (mpegâ€™s) in My Documents\NeroVision\Imported Video
Files. These files can be quite large so you may want to
put them elsewhere in your system. Close this dialogue box.
Click on Video Options and choose NTSC for the expected
video mode. All other options can remain the same. Close
the dialog box.
From Make a DVD>DVD-Video Click here.
On the next screen, click on the More button at the bottom
of the screen. You will see the option of choosing
â€œCreate Chapters Automatically.â€
If you click this and close before importing video, it will
apply chapters every two minutes in a regular movie and you
will not need to use the Create Chapters page. Chapters are,
however, optional and the program does create PGC info
so that you can fast forward and rewind. Choose video
options from the MORE button and choose the tab for DVD
Video. If you choose AC-3 audio, either two or 5.1, you have
the best chance that the resultant DVD will be playable
on most stand alone players. Now you can either import a from
your folder on the hard disk.
Click on the first VOB file for the main movie. For example,
VTS_01_1.VOB if Title 1 is the main movie,
hold down the Control key and add the other VOBâ€™s in order.
Click open and then â€œYes.â€ to integrate the VOBâ€™s as one title.
After about 10 minutes the movie will be shown at the top of
the filmstrip. You can add other titles (previews, trailers, interviews)
but the resultant DVD may require shrinking, which Nero can
certainly do. This just prolongs processing time.
Double layer disc burning without shrinking is also an
After you are done adding files, you can choose to have Nero
create chapters according to its method as outlined on
Neroâ€™s Chapters page To get there, just click â€œCreate
Chaptersâ€ after you have added your videos.
You can also choose to create the chapters yourself, which
can be a little tricky. The Chapters generated from the
chapters page will appear on separate menus but the
every-two-minute chapters (see preceding paragraph) do not appear
as menu items.
Next, the menu:
The menu screen has a number of options. At the top on the
right of the menu screen, there is a drop down box where you can disable the
menu to save time and
DVD disc space. If you choose a menu, each of your titles
will have its own clickable icon. After previewing the DVD, you can burn to a
hard disk folder or
directly to DVD. Nero will ask you if you really wanted to
burn a PAL DVD since most of the content is PAL. The answer must be NO. I have
the first DVDs should be burned to a completely new hard
disk folder to verify that everything is going as expected. Create a new disk
folder each time since Nero may
not erase the contents of a previous folder as expected.
You can burn from the hard disk folder with various programs or from Nero
Burning ROM or Express.
If you choose to burn from Nero Visionand it suggests that
the resultant DVD might not be playable, go ahead and hit proceed. The process
should take about two
hours on a fast machine. NTSC DVDâ€™s can also be converted to
PAL by choosing PAL from the Video Options at the beginning. The aspect ratios
automatically. When burning to a Hard Disk Folder or DVDR,
allow the DVD to be PAL mode although Nero will suggest that it should be NTSC.
One word of caution, Nero Vision will create MPEG files of
your imported VOBâ€™s in a folder in My Documents>NeroVision>Imported
Video. These files
are as large as the DVD so your need to erase once you have
successfully burned your DVD or you will have disk space issues eventually. The
same goes for
your new folders on the hard drive.
The other program that can be used is INTERVIDEO DVD Creator
One benefit of using it to convert From NTSC to PAL or vice
versa is that the DTS audio is not a problem. If more than one audio language
it is still probably a good idea to rip the DVD and remove
the unneeded language. The slight disadvantage in using this program is that
there is no
fine adjustment for shrinking the video. You must choose HQ
or GQ or SP, etc. which results in changes in the file size before burning a
If the file size is too large, the excess is displayed in
red (before burning) and DVD Creator will refuse to continue. Like Nero Vision,
will accept video from a number of sources but transcodes
them very slowlyâ€”it can take many hours to convert a video. There is no
file size when converting between formats as in some
programs and the results are excellent.
When you first start the program, it will ask certain
questions about the desired resultant video system (NTSC or PAL) and whether
you are burning for a DVD
or recorder (DVD). Use Dolby Digital sound .for the output
format . The default quality may be HQ but that is a very high data rateâ€”more
than the typical
4000 Kbits/sec normally used in DVDs. SP is a better
choice.. Then import your movie. A VOB is not a default file type (Files of
type) when importing.
Choose ALL file types at the drop-down box at File>Open.
Then you will see your VOB files. You can import them in any order but there is
to import the menus. (VTS_0X_0.VOB). You will have to
arrange your VOBs in the correct order on the timeline in the Edit mode
(Figure 8). It takes a
few seconds for each VOB to appear in the program. Then make
a menu and add chapters if desired. The chapter addition every X seconds is
simple and fast.
When you burn, you will see that the program has added
enough data from the menu (if chosen) to increase the overall file size. You
may need to reduce video
quality using the drop down box . The DVD may end up being
twenty percent smaller than the original even if it was a normal 4.7 Gig movie
to begin with.
However this is due to the lack of fine tuning during the
â€œshrinking â€ process. You can see how this works below:
Fortunately, however, Intervideo DVD Creator 3 will burn a
Double-Layer disc. With a DVD of capacity less than about 5 Gig,, no reduction
would take place in DVD HQ mode and a DL blank DVD. If
you want to fill the DL disk, a slight step down is quality may be necessary
if your original
DVD is about 8 Gigs total.. This is due to the size of the
menu and changes in file sizes between video modes. DL blanks do not currently
play as consistently
in stand alone players as
DVD5 + or - R copied discs.
The quality of conversion is very high but the overall time
required by this program is very great.â€”at least five to six hours with a fast
machine With dual-layer
burning, less shrinking is necessary
Subtitles are a subject all to themselves. Nevertheless,
there was one PAL DVD whose subtitles seemed important to retain. Although
other methods of doing this
are found on the Net, I found the commercial program
DVD-Lab PRO to be very helpful. Here are the steps: Use SubRip to extract the
subtitles from the DVD
and Save an SRT file. Using Unicode characters instead of
standard ASCII caused the SRT file to be unreadable by DVD-Lab PRO. Load the
SRT file into the
subtitle track of DVD-Lab PRO as an import and create an SP1
file accordingly. Use a program like Intervideo DVD Copy or others to shrink
(movie only) down to about 4.1 Gig. This is because DVD-Lab
PRO will not shrink videos. Use Nero Vision to import the shrunken PAL video
EXPORT it as NTSC file. The exported video is an MPEG which
can be loaded as an asset to DVD-Lab PRO, which will separate the file into m2v
AC3 files.. Add the resultant files into the same track as
the subtitle. Compile the DVD then burn it..
5. OTHER AUDIO TRACKS
Programs like VOBEdit and PGCDemux will separate out the
various audio tracks from a DVD. We discussed the method for converting a
PAL DVD to an NTSC MPG file above. The MPEG file can
stripped into m2v (video) files and audio files of various types with freeware
MPEG_STREAMCLIP. The audio files would be discarded since
more than one audio track has been demuxed in VOBEDIT and can be added
in DVD-Lab PRO. The m2v file for the entire movie can
becombined with up to two AC3 files in DVD-Lab PRO. The video audio sync has
not been a problem.
I did use many other freeware, shareware and commercial
programs to try perform the conversions but none were as effective and
reliable as the programs above. Ulead DVD Movie Factory 5 or
Video Studio 10 will shrink and transcode (i.e. change from one video format to
files but it reduced the size of the resultant DVD when
converting from PAL to NTSC but not vice versa!. Other Shareware or â€œNet sale
onlyâ€ software either
crashed during conversion, lost audio, reduced file sizes
unpredictably, or were unreliable from DVD to DVD. Reliable conversion between
the two video modes
can be accomplished with the two commercial programs
mentioned above. Both can be downloaded from the Net.
