This is a brief tutorial designed to show professors and students how to
quickly assemble a simple DVD of film clips on a Mac. The tutorial assumes
that will be pulling your clips from commercial DVDs protected by DRM, and
that your Mac is equipped with a DVD burner. The U.S. Copyright Office has
issued an exception to the DMCA that allows instructors and students to
circumvent copyright protection in assembling noncommercial videos for the
purposes of classroom education, criticism, and commentary. (Read the
specific language of the Copyright Office’s exemption here.)

The following instructions are not the only way to do this, but this is a very
quick and reliable system. Also, there are many programs that will help you
extract and convert video from DVDs, but the ones used in this tutorial are
free, stable, and well established.

                         WHAT YOU WILL NEED:

1. A Mac running an updated version of OS X
2. A DVD burner (either an external burner or a built-in CD/DVD
   reader/burner, which Apple calls a SuperDrive)
3. Two free programs: Mac the Ripper and MPEG Streamclip. Both of
   these programs are mature, stable, and safe for your computer.
   Instructions for downloading them are below.
4. One program that is probably already on your Mac: iDVD.
                     THE PROCESS IN A NUTSHELL:

1. Download the programs you will need.
2. Rip the rough clip you want using Mac the Ripper.
3. Select the exact clip you want (to the frame) and convert it to Quicktime
   using MPEG Streamclip.
4. Burn the clip to DVD using iDVD.


First, download Mac the Ripper. Despite its unsavory name, remember that
you are legally entitled to circumvent copyright protection for
educational-noncommercial purposes. Mac the Ripper is a legal
program that enables you to do so.

                    To download Mac the Ripper, go to and follow the directions for
                  downloading and installing the program.

Second, download MPEG Streamclip. This program will convert your clip to a
format that you can easily work with.

                    To download MPEG Streamclip, go to
        and follow the
                directions for downloading and installing the
                     USING MAC THE RIPPER

Insert the DVD that has the clip you want on it into your drive and open Mac
the Ripper. You should have a screen that looks something like this:

The top half of this screen gives you a lot of information about the DVD,
such as whether it is copyright-protected using Macrovision, etc. The
default settings on this screen will work most of the time for most
people: it will remove the Macrovision protection, remove any region
encoding, etc.
Next, click on the "Mode" button in the middle of the screen. You should
have a screen that looks something like this:

Note that the default setting is "Full Disc Extraction," meaning that it is set
to extract the entire disc including the main title, any menus, any special
features, etc. Since you only want a short clip, to save time you should
extract only the chapter or two of the DVD that you want to show in class.
Here's how that looks:
Choose "Title – Chapter Extraction" and then, from the choices on the
bottom row, select the chapter(s) you want. In the above example, I want
only chapter 19, so I selected Start Chapter 19 ("SChpt 19") and End
Chapter 19 ("EChpt 19").

If you are not sure which chapter contains the scene you want, you may
have to leave Mac the Ripper, go into DVD Player, and look through the
chapters until you find the ones you need.

NOTE: On the Mode page, you can also decide whether to extract subtitles,
a second audio program, alternate camera angles, or other elements that
your DVD may contain. See the Help info for Mac the Ripper for how to do
this. For the purpose of this tutorial, we're assuming you want the primary
audio program and no subtitles.

Once you have selected the elements that Mac the Ripper should extract,
click on "GO!" and extraction will begin. This should only take a couple of
minutes for a single chapter. The first time you rip a DVD with Mac the
Ripper, you may get an error message like this:

It is safe to click Continue here. To avoid it in the future, however, click the
Disc button (next to the Mode button), and then click the RCE Region button
(which is probably set to Off) and pick a region. For more about what
regions mean, please see the Mac the Ripper Help info.

When the process is complete, you will have a folder on your Desktop with
the name of the DVD (for the above example, mine was "CITYLIGHT FILM
Title 1 (Ch19)." That folder should contain another folder entitled "VIDEO_TS."
And that folder should contain a .VOB file, also with the name of the DVD.

The next step is to open this .VOB file in MPEG Streamclip.

Open MPEG Streamclip; it should look something like this:

Now you simply drag-and-drop the .VOB file that you created with Mac the
Ripper onto that middle square with the five dots:
In a few seconds, you should see a screen, with the play button, time slider,
etc., right under it; this is the chapter that you extracted from the DVD:

You can now watch your rough clip by hitting the play button. You can also
use the slider to quickly jump to a different point in the clip.

Now you can select the exact clip you want, to the frame, simply by setting
an "In" point (i.e. the first frame you want) and "Out" point (the last frame).

First, play the clip until the first frame you want comes on and hit pause;
you can use the right and left arrow buttons on you keyboard to move
through the clip frame-by-frame.
Once you have the starting frame that you want, press "I" (for "in") on your
keyboard. You'll notice that everything before that point in the slider gets
grayed out, and there will automatically be a frame count entered in the
In/Out box on the lower right:

Similarly, find the last frame you want and press "O" on your keyboard to
set the out point:
Everything in the slider timeline should be light gray except for the segment
you want, which should be dark gray. For most users most of the time, the
default settings for video, audio, etc. should work fine. You are now ready
to export this clip to iDVD.

To convert the clip, click on the "File" menu in MPEG Streamclip and choose
which format you want. You'll notice that you have many options; for NTSC
and PAL users, the quickest and easiest for throwing together a quick clip
DVD is the DV (digital video) format. Select "Export to DV":

You will get a screen that looks something like this:
Make sure the desired standard (NTSC or PAL) is selected; other than that,
the default settings will once again work for most users most of the time.

Click on "Make DV" on the bottom right. On the save screen, select the
name of your file and where you want it saved, and MPEG Streamclip will
begin exporting your clip as a DV movie. This will only take a few minutes
for a short clip:

Once MPEG Streamclip has finished exporting the clip, you are now ready to
assemble a clip DVD using iDVD.

iDVD is Apple's simple program for creating DVDs; if you have a DVD burner
built into your Mac, you should have iDVD on your computer. If you are
using an external DVD burner, refer to the directions that came with the
burner on what software to use.

For iDVD, it is a simple matter of choosing a "theme" or look for your DVD,
dragging-and-dropping your QuickTime files onto the workspace, and
burning the DVD.

When you open iDVD, you get the following screen (note that I'm still using
an older version of iDVD, but the basic procedure hasn't changed):

Select "Create a New Project," then select the name of your DVD and where
to save it. When iDVD opens, choose a theme for the DVD by clicking on
"Customize" and selecting from the different presets. Because all I need is
simplicity and functionality, I like to use the "Brushed Metal Two" theme:
Once you have a theme you like, you can replace any text by clicking on it
and writing your own titles, captions, etc. Then you can drag-and-drop your
clips onto the workspace, which represents what you will actually see when
you play the DVD:

If you want a different frame from the clip to appear on the menu, just click
on the picture and use the slider to select a new frame:
You can add more clips as desired in the same way so that all of your clips
for a given lecture will be on the same DVD. You can also organize your
clips into folders by clicking on the "Folder" button to add a new folder;
clicking on that folder will then take you to a new screen where you can add
clips or more folders.

In the above example, clicking on "Chaplin Lec." will take the user to a new
screen with my Chaplin clips:
Once you have all of your clips assemble, organized, labeled, etc., you can
"test drive" the disc by clicking on "Preview" on the lower right. This will
simulate the operation of your disc in an actual DVD player. This brings up a
virtual remote control with which you can navigate through menus, make
sure all of the clips play, etc.

When everything is to your liking, you are ready to burn the DVD. Insert a
blank DVD and click "Burn" on the lower right.

NOTE: For best results, use higher-quality, non-rewritable DVDs. I have
never had a problem with Maxell DVD-R discs, which have always recorded
flawlessly and have played in every player I've tried them in.

After your disc has finished burning, eject it and then put it back into your
computer to see if it will play using your DVD Player. If not, then you know
right away that something went wrong and can try again; if it does play,
that usually means that everything went just fine and the disc is ready for
classroom use. Obviously, it pays to test your disc in your classroom player
before class starts to make sure that the disc plays without a problem,
especially if using older equipment.

That's it! If you have any questions or problems, feel free to email me:
