Hack 58 Create a Rolling Movie Title

A cake isn't really dessert
without icing, and a movie isn't complete without
titles. Here's a simple way to create tasty
Hollywood-style rolling credits.

We've been working in QuickTime Pro for the previous
movie-editing hacks [Hacks Section 5.11, Section 5.12]. QuickTime
is featured in this book for a number of reasons. First,
it's cross-platform, so Mac and Windows users are on
equal footing. Second, it's extremely powerful for
its cost (US$30). Third, it's essentially the native
format that your digital camera uses to record movies, so why go
through nasty conversions when you don't have to?
But finally, and just as importantly, QuickTime is very hackable.
This hack illustrates that point beautifully.

Rolling credits and titles are a Hollywood tradition. They have
graced movies made by Charlie Chaplin to Woody Allen. And they can
add a professional touch to your digicam videos just as well.

I'm not going to get into the various movie-editing
applications that require you to convert your QuickTime footage just
so you can add rolling titles. Instead, I'm just
going to use QuickTime Pro and your favorite text editor.

5.13.1 Using Text Tracks

Text tracks are
low-bandwidth, vector titles you can add to your movies. The
QuickTime web site (http://www.apple.com/quicktime/tools_tips/tutorials/texttracksl)
explains how to add text to your movies. The problem is, you
can't easily control how the text looks by using the
basic method that most tutorials describe.

But if you get into a wonderful, hackable, hidden feature in
QuickTime called text
descriptors, you can create just
about any type of title your imagination can conceive. Think of text
descriptors as tags that tell QuickTime how your title should look.
You can see the entire list of these tags at Apple's
web site (http://www.apple.com/quicktime/tools_tips/tutorials/textdescriptorsl).

To put them to work for you, open Notepad, TextEdit, or your favorite
text editor. Then, enter the following text:

{QTtext} {font:Arial Black} {bold} {anti-alias:on} {size:18} {textColor: 65535, 65535, 65535}
{backColor: 0, 0, 0} {justify:center} {timeScale:300} {width:320}{height:240} {language:0}
{textEncoding:0} {scrollin:on} {continousScroll:on} {scrollOut:on}
[00:00:00.000]
[00:00:02.000]
A Simple Movie Title
[00:00:08.000]

You'll only have to do this once. From then on, all
you have to do is use Save As to create different rolling titles.

Once you've entered this information, save it as a
.txt file. Then, open QuickTime and select
Import from the File drop-down menu, as shown in Figure 5-18.

If you're working in Windows,
you'll be greeted with a dialog box that allows you
to navigate to your text file. Once you do, highlight it and click
the Convert button. You'll be greeted with another
dialog box. All you have to do is provide a new filename (it can be
anything) and click Save. QuickTime will build the rolling title for
you.

Mac OS X users follow a similar procedure. Select Import from the
File drop-down menu, navigate to your text file, and click on the
Open button. Figure 5-19 shows the complete title in
QuickTime on Mac OS X.

Your rolling title is now ready to view. When you click the Play
button on the viewer, you'll see "A
Simple Movie Title" scroll upward. You can use the
title as is, or you can trim off parts of it to shorten it [Hack #57] .
Once you have the title edited to your tastes, copy it to the
clipboard by choosing Copy from the Edit drop-down menu. Then, open
the movie to which you want to add the rolling title. If this is an
opening title, make sure the receiving movie is
set at the beginning. Select the Paste command, and your title will
now be placed at the beginning of the movie.

5.13.2 Customizing Your Title

If you want a different
look, all you have to do is change the appropriate text descriptors,
do a Save As, and import in QuickTime. For instance, if you want to
add a credit line to your rolling title, it might look like this:

{QTtext} {font:Arial Black} {bold} {anti-alias:on} {size:18} {textColor: 65535, 65535, 65535}
{backColor: 0, 0, 0} {justify:center} {timeScale:30} {width:320}{height:240} {language:0} 
{textEncoding:0} {scrollin:on} {continousScroll:on} {scrollOut:on}
[00:00:00.000]
[00:00:02.000]
A Simple Movie Title
[00:00:08.000]

[00:00:14.000]

The timestamp numbers that follow the text determine how fast the
text scrolls. If you want to slow down the movement, make the
timestamp longer. For example, go from [00:00:04.000] to
[00:00:08.000].

If you prefer to have blue text on a white background, use these
descriptors:

{textColor: 0, 0, 65535}{backColor: 65535, 65535, 65535}

Or, for black on a white background, use these:

{textColor: 16448, 0, 16448}{backColor: 65535, 65535, 65535}

You can also change font size, font type, and the width and height of
the frame. It's amazingly easy and fast. Who needs a
cumbersome user interface when you can author with a simple text
editor? You can also add more descriptors. The complete list is
online at http://www.apple.com/quicktime/tools_tips/tutorials/textdescriptorsl.

5.13.3 Final Thoughts

I usually make my rolling title and then trim it before adding it to
my movie. One of my favorite tricks is to trim the title so that it
stops in the middle of the screen instead of rolling off the top
edge.

If you plan on putting your movie on DVD and playing it on a TV, be
sure to leave plenty of elbow room on the outer edges of the letters.
Televisions often show less viewing area, and your titles might be
missing a few digits if they span the width of the frame.

Finally, keep your titles simple and brief. You certainly
don't want the credits to last longer than the movie
itself!
