5: From Player to Creator - Part 1

Beginning with version 3.0, every version
of QuickTime
comes in two flavors: the free-of-charge, bare-bones
QuickTime, which basically enables you to play QuickTime
movie files, MP3 files and a whole slew of other audio/video
file formats, and the more enigmatic “QuickTime Pro”
($29.99US), which provides you with a full set of
additional features.
What are those features, and what do
they enable you to do that the basic, free-of-charge
QuickTime does not? In this new series of articles,
we will dig into QuickTime Pro’s feature
set and try to highlight some of the most interesting
aspects from a “consumer” point of view.
The “Pro” in QuickTime Pro
While it is quite obvious that the
“Pro” in QuickTime Pro stands for
“Professional” and implies access to a
range of features not available in the “consumer-level”
QuickTime, its modest price tag ($29.99US, electronic
download) is also a clear indication that it certainly
doesn’t belong in the same league as real
“Pro” applications, such as Apple’s
own $999 Final
Cut Pro (professional counterpart of the
consumer-oriented iMovie)
or its $999 DVD
Studio Pro (professional counterpart of the
consumer-oriented iDVD).
In fact, QuickTime Pro is a product
that resists categorizing. It includes features that
used to be available free-of-charge as part of the
standard QuickTime package and that seem to have been
removed from it due to commercial considerations —
but it also includes features that actually complement
those provided by consumer-level tools such as iMovie
and iDVD. It is, in a way, the “missing link”
between the passive enjoyment of the Web’s multimedia
content and the creative use of Apple’s consumer-level
multimedia software.
At the same time, it should be said
that, while it cannot compete against professional-level
multimedia software, QuickTime Pro offers a very
wide range of features that can achieve results that
are more than satisfactory, even for the reasonably
demanding “creative consumer.”
In this first instalment of our QuickTime Pro
series, we will review some of the functionality provided
by QuickTime Pro.
Before we start, however, I should
specify that I’ll be focusing on the Mac OS
X version of QuickTime Pro in these articles
(version 5.02). The “classic” version
of QuickTime Pro for Mac OS 9 (still available
under Classic in Mac OS X as well) is, however, more
or less identical — and a registration number
purchased for the Mac OS 9 version works for the Mac
OS X version as well (and vice versa). In addition,
QuickTime Pro is also available for Windows,
providing PC users with some of the same functionality.
Saving Movies
The first obvious difference between
QuickTime and QuickTime Pro is the ability to
save movies. The basic, unregistered QuickTime Player
application is a bare-bones affair, with only the
required functionality to play compatible
audio or video files or experiencing audio or video
streams (when they are available in QuickTime format).
When a movie is embedded in a Web page
(i.e. shown within the page and not opened with the
QuickTime Player application), the right-most button
in the control bar under the movie (when it is visible)
gives you access to a number of options.

| QuickTime
Pro plug-in pop-up menu |
In this menu, if you own QuickTime Pro
(and if the movie in question has not been locked
by its author), the two “Save” commands
that are normally disabled become available (once
the movie is fully loaded) and allow you to save the
embedded movie as a QuickTime “.mov” file
on your hard drive.
In the QuickTime Player application
itself, the difference between QuickTime and QuickTime Pro
is obvious when it comes to saving files:

| Differences
between QuickTime and QuickTime Pro |
While the regular “Open”
menu only contains commands designed to let you play
stuff, the “Open” menu in QuickTime Pro
contains additional commands for both opening/importing
and saving/exporting.
QuickTime Pro’s “Save
As…” command gives you the ability
to save the currently active movie file in just two
ways: either as a “self-contained”
movie, which is what you’ll want in most cases
(i.e. as a file that contains the full movie and can
be transferred anywhere), or as a very small file
(weighing a few kilobytes only) that behaves as a
sort of “alias” to the original movie
and doesn’t contain the movie itself, but behaves
as if it did, using “pointers” to the
actual data.
|
|

Pro "Sav As..." dialog box |
To determine if a movie contains any
pointers (to other movie files), you need to use the
“Get Movie Properties” command
from the “Movie” menu (more on
this later).
Exporting
The “Export…”
command, however, gives you access to an amazingly
— and sometimes confusingly — wide array
of options.
|
|
| QuickTime
Pro Export formats |
Some of these options have to do with
converting your QuickTime file into other proprietary
formats, such as Microsoft’s own “AVI”
video format.
Others, such as “DV Stream”,
let you to export your QuickTime file in a format
that will enable you to edit the file using other
applications. The “.dv” format, for example,
is the uncompressed digital video format that is used
by iMovie (and Final Cut Pro) to edit movies
(cut out sections, add visual effects, etc.).
You can export a QuickTime movie as
NTSC (North American) or PAL (European) DV stream,
depending on the format used by your video devices.
This will, of course, cause QuickTime to blow up your
movie image if its size is smaller than the resolution
used in these formats. This will also obviously result
in a file that’s much larger than the original.
If the exporting takes time, QuickTime Pro
will then display a progress bar while the file is
being exported, and let you switch to another application
while the exporting is taking place.
|
| QuickTime
Pro Exporting progress bar |
In the example that I have used in
my screen captions, the lo-fi version of Apple’s
“Rip. Mix. Burn.” ad optimized for slow
modem connections has a resolution of 240x180 pixels
with a frame rate of approximately 8 fps, for a total
size below 1 MB. After exporting is as an NTSC DV
stream, the resulting file was a whopping 104 MB,
consisting of a DV stream with a resolution of 720x480
pixels and a frame rate of 29.97 fps.
|
| Exported
DV file |
This step is required, however, if
you want to further edit the file with a video editing
tool such as iMovie. It obviously only produces satisfactory
results with movies that have a good resolution and
frame rate to begin with.
Image Sequences
The “Image Sequence”
format, in the “Export…” command,
lets you save a movie file as a series of image files
— for example, a series of 20 JPEG images per
second, based on the frames of the original movie.
|
| Exporting
image sequence |
This can be a useful way to either
extract consecutive stills from a movie or decompose
the movie into a set of images (all with the same
name followed by a number, such as “Movie 01”,
“Movie 02”, “Movie 03”, etc.)
that can be manipulated individually before re-composing
a new movie with the modified set of images.
Indeed, using the “Open Image Sequence…”
command, you can then open the first in a series of
images that all have the same name followed by a number,
and QuickTime Pro will let you set a frame rate
(from 30 frames per second to 10 seconds per frame)
for the resulting movie, which can be anything from
an actual, high-quality video clip to a slide show
consisting of each of the pictures displayed for a
given number of seconds.
|
| Options
for opening image sequence |
One small caveat, however: Using the
“Open Image Sequence…” command
will import your set of pictures right into
the currently active “player”, effectively
removing its existing content. Make sure that you
open a “new player” first if that’s
not the behavior you intended. In fact, this is a
more general problem with the QuickTime Player interface:
sometimes using an “Open” command will
cause the Player to open a new “player”
window to display the contents of the file you’ve
opened, sometimes it will replace the contents of
the currently active “player” window with
the contents of the file you’ve opened. A more
consistent terminology (“Open”
vs. “Place”, for example) would
be more appropriate.
For fancier slide show effects, such
as fade-in/fade-out transitions, you will need to
use iMovie — but this “image sequence”
functionality is a versatile tool that enables you
to create easy-to-distribute slide shows fairly quickly
and easily.
Additional Formats and Settings
QuickTime Pro can still export
your files in other formats. The ones beginning with
“Sound to…” (“Sound
to AIFF”, “Sound to Wave”, etc.)
are effectively a way to extract the sound track of
your movie file — but this form of extraction
also performs a conversion at the same time,
based on the selected settings.
|
| Options
for exporting as sound |
In addition to the various sound formats
themselves, settings include sampling rate, compressor, etc.
(depending on the sound format selected).
The file format called “FLC”
is an animation format, while “BMP” is
an alternative still image format used in the Windows
world. The “Hinted Movie” format
is a more specialized format designed to help you
optimize your movie file for Internet streaming.
It should be noted that all
the file formats available through the “Export…”
command come with their own set of additional settings,
available in a second pop-up menu called “Use:”
below the “Export:” pop-up menu.
|
| Menu
of settings for exporting as sound |
This menu, whose contents vary depending
on the file format selected in the “Export:”
pop-up menu above it, gives you access to an array
of pre-defined settings for the selected file format,
as well as the last settings you used (as “Most
Recent Settings”), if you have already exported
something using the file format in question.
If none of the settings suggested suit
you, then you can use the “Options…”
button to access even more options and change each
of them individually, in a separate sub-dialog box.
|
| Settings
for exporting as movie |
This sub-dialog box, whose contents,
again, vary depending on the file format selected,
can itself span even more dialog boxes with more settings.
|
| More
settings for exporting as movie |
|
| Even
more settings for exporting as movie |
Needless to say, it is impossible to
illustrate here all the possible combinations of settings
that can be accessed through this “Options…”
button. The various screen shots in this article are
really just the tip of the iceberg — but this
cornucopia of settings clearly demonstrates that QuickTime
is a very mature piece of software that has been designed
to accommodate a whole array of file formats and creative
needs.
By purchasing QuickTime Pro, you
effectively gain access to all the functionality “hidden”
within the apparently simple QuickTime technology,
and, in that respect at least, QuickTime Pro
fully deserves its “Pro” label.
The only gripe I have with this functionality
is that, from a “consumer” point of view,
some of the settings are far from being self-explanatory
and require that you do some research and a lot of
experimenting on your own. The various compressors
used for video compression, for example, have names
such as “Cinepak,” “H.261,”
“Motion JPEG A,” etc. Unless
you have done some research, those names are likely
to be all Greek to you, and, in order to find out
what each compressor does to your movie, you’ll
need to experiment with it.
Finally, the other commands included
in the “File” menu are common to
QuickTime and QuickTime Pro. They let you open
a movie on the Web directly by typing its exact URL,
and print the current frame.
Next time, we will look further into
QuickTime Pro’s editing
commands per se, i.e. the commands that let you select,
cut, copy, delete and rearrange the various components
of a movie file. Stay tuned!
