Captioning
your multimedia
presentations with
Hi-CaptionŽ and Flash™
2004 and Flash 8
The
Internet has become an
increasingly easy way to
publish and find
information.
Increasingly Web
developers are providing
this information in
multimedia format
through technologies
that provide a rich
multi-sensory
presentation. However,
until recently this
information was not
accessible to all
Internet users. Some
users rely on
third-party solutions to
translate information to
them. Today there are
accessibility standards
and guidelines that Web
developers can follow to
ensure that users of
assistive technologies
can access their
Internet presentations.
Captions provide the
ability for users who do
not have the ability to
access the audio portion
of a multimedia
presentation, to still
have access to it. This
tutorial will introduce
the reader to closed
captions and then
discuss the creation and
use of closed captions
with Hi-Caption and
Macromedia Flash and the
Hi-Caption viewer. To
follow this tutorial,
you will need HiSoftware
Hi-Caption and
Macromedia Flash.
If
you do not have a copy

Why Closed Captions
Closed captions are
captioned text that can
be turned on or off by
the user, allowing
flexible and accessible
delivery of your
multimedia project.
Closed Captions solve
real problems while
providing design
flexibility:
-
Ability to translate
caption text to
different languages
(Allowing Wider
Distribution.)
-
Compliance with a wide
range of accessibility
guidelines and
standards.
-
Ability to have access
to full movie when
technical capabilities
do not include sound.
Hi-CaptionŽ
HiSoftware Hi-CaptionŽ
is a unique solution
that allows designers
and developers to
deliver rich multimedia
content that meets their
accessibility and
distribution
requirements. The
Hi-Caption solution
consists of two main
parts, the Hi-Caption
Captioning System and
the Hi-Caption viewer
component for Flash:
Hi-Caption is a Closed
Caption Generation
system that allows users
to easily create caption
text for their
multimedia. The system
comes complete with:
-
Transcript Import
Wizard
-
Transcript Creation
Capabilities
-
Project Support
allowing for
collaboration
-
Direct Viewing of your
flash movie allowing
for a complete watch,
pause and caption
solution.
The
Hi-Caption viewer
Component - The
Hi-Caption viewer
Component provides a
100% customizable
captioning interface.
Remember, one of the
most important gains
with closed captions is
that the developer can
easily define the
characteristics of the
captions to better match
their presentation. The
Hi-Caption viewer allows
for customization of all
design elements and
allows you to use the
default captioning area
or to define your own.
Additional information
about the Hi-Caption
viewer component will be
provided later in this
tutorial.
Getting Started
For
the tutorial we will use
the sample media files
that can be downloaded
from the HiSoftware web
site (see the link
provided at the top of
this tutorial).
In
this tutorial you will:
-
Create a simple Flash
movie (or use the
movie provided)
-
Create a caption file
using Hi-Caption
-
Modify the Flash
movie, using the
Hi-Caption viewer
Component, to add
captions
-
Be
introduced to
multi-language
captioning
-
Be
introduced to the
theory of buffering
initial captions
-
Be
introduced to some
captioning guidelines
Creating the Caption
for the Flash File
The
Caption file is an XML
file that will be usable
by the Flash
Movie/Player. The File
is used to display
captions which are
synchronized with the
movie when it is playing
in the Flash Player. The
Hi-Caption SE Interface
allows the user to
interact with the movie
while creating the
captions. Before you
begin there are several
items to consider:
-
Using individual
captions greater than
three lines may make
your captions less
usable
-
The amount of words
that can be displayed
in the caption area
depend on the size
that you will define
in Flash as your
captioning area
-
You should always
spell check your
captions
To
create the caption file
follow the steps below.
Starting Hi-Caption
-
From the Windows Start
menu, select Start,
then Programs, then
HiSoftware Hi-Caption,
then Hi-Caption .
Hi-Captionthen opens
on your desktop.
-
From the File menu of
Hi-Caption, select
Open, then Select
Media File. In the
Open dialog, select a
file named
dav02-start.swf (or
whatever you named
your file if you are
not following the
tutorial exactly.)
This is the movie file
you created in the
previous section.
Hi-Caption's interface
will then look like
the picture below.

-
The left portion of
Hi-Caption displays a
media control,
depending on which
type of media file was
opened, while the
right side displays a
grid where captioning
text will be added.
(If you had opened a
Windows Media file, or
a RealNetworks file,
then one of those
controls would be
present in the left
pane.)
-
From the Settings
menu, select Available
Classes and make sure
that ENUSCC is in the
list. If it is not in
the list, click on the
Add button and choose
enuscc.hmccss from the
SAMIstyles subfolder
of the Hi-Caption
installation
directory.
-
Play the media file
using the Play item
found under the Player
menu at the top of
Hi-Caption, or the
media control buttons
below. After 5-10
seconds or so, pause
the file using the
Stop item found under
the Player menu at the
top of Hi-Caption, or
the media control
buttons below.
-
Next, after you have
stopped the media
file, click on the Add
SYNC button. This
will add the time in
which you first
started playing the
media file.
Note: This value will
be measured in frames
(if you are using a
Windows Media or Real
Networks file, the
time will be in
milliseconds.)
Hi-Caption SE will add
the Time Start to the
first column in the
grid.
Next, select your
class from the drop
down menu in the Class
column.
Next, you can
optionally select the
speaker from the drop
down menu in the cell
in the first row of
the grid under the
Speaker column.
Next, you add the text
spoken by the media
file into the fourth
cell in the first row,
found under the
Captions column. Add
SYNC works by adding
the time in which the
Flash file was last
played. Because you
do not know what text
will be spoken prior
to your hearing it,
the feature works by
letting you listen to
the text, making a
mental note of it, and
then when the button
is pressed, allows you
to enter the starting
time for that span of
text and then type it
in.
If you are lucky
enough to have been
provided with a
transcript of the text
in text or Rich Text
Format (RTF), then you
can use the Import
Wizard found under the
Tools menu. The
Import Wizard will
load all the text into
the grid, then the
Step Current button is
used to set the frame
timings, while the
Flash file is played
in Hi-Caption.
-
Again, play the file
again for 5 -10
seconds or so and then
pause the file. Click
on the Add SYNC
button. Next, in the
Captions field, we add
the captioning for
that portion of the
file.
-
Repeat until the whole
media file has been
captioned. Hi-Caption
will have data
populated in the
fields, like the
picture below.
-
When done, select Save
from the File menu.
This saves the SAMI
file.
-
To
review and adjust your
captioning times,
rewind the Flash file
to the beginning and
play it. Use the Step
Current button to add
the current time to
the grid and to then
skip to the next time
sequence.
-
When you have
completed your
captioning, and are
happy with the
timings, then select
Save from the File
menu. Next, select
Save as XML from the
File menu. The
Hi-Caption viewer for
Macromedia Flash will
use the XML file to
display captioning in
Flash. By default,
the XML that is
generated by
Hi-Caption will be in
ANSI format. This
format is
approximately 1/2 the
size of Unicode
format. If you are
using any special
characters from other
languages in your
captioning file, then
you need to save your
XML in Unicode
format. To change the
format, check or
uncheck Generate
Unicode XML from the
Settings menu in
Hi-Caption.
-
From the File menu,
select Save Transcript
As and save a text
transcript of what was
captioned. Print this
file out for use
later.
Adding
the Hi-Caption viewer to
Macromedia Flash
We
now have a flash movie
that has a corresponding
file with the captions
and time points that
will allow for closed
captioning to be seen
when someone watches the
Flash movie. In order to
use this captioning file
in Flash we must install
the Hi-Caption viewer
for use with Macromedia
Flash (if you have not
done so already.) If you
have not installed the
component, follow the
simple installation
instructions that
follow.
Installation of the
Hi-Caption viewer
-
Locate the
Hi-CaptionViewer.mxp
file located in the
extension folder of
the HiSoftware
Hi-Caption SE for use
with Macromedia Flash
installation
directory. On most
user's systems, this
location will be
C:\Program
Files\HISC\Hi-Caption
SE\extension, but this
can vary if a
different installation
path was selected
during installation.
-
After locating the
Hi-CaptionViewer.mxp
file, double-click on
it to use the
Macromedia Extension
Manager to load the
Hi-Caption viewer into
Flash.

Adding Captioning to
the Flash File
We
are ready to add
captioning to the Flash
movie at this point.
When adding the
component we can
control; location, size,
and many other
properties. Follow the
below steps to enable
the flash movie to use
the caption file you
created in the previous
section of this
tutorial:
Setting Up the
captioning display in
the Component
-
With your Flash file
opened, locate the
Components panel in
Flash and expand the
HiSoftware tree item
in the Component tree.
Drag the Hi-Caption
viewer from the
components view to
your Stage. In our
example here, we
dragged an instance of
the Hi-Caption viewer
to just below the
movie file.

-
Click on the instance
of the Hi-Caption
viewer in your stage
to display the
component properties.
You will now edit the
component parameters.

-
The first component
property we will
modify is the Show
Captions property,
click to change this
property to TRUE
because we wish to
display the
captioning.
Note: This will help
you to set up the
design of the
captioning area,
however, for the final
creation of the movie
you may want to set
this to false. If you
set this to false,
then when watching the
movie users can choose
to enable the captions
if they wish to see
them (This is one of
the advantages of
closed captioning.) If
it is set to false the
captioning area does
not view and a user
can simply click on
the "CC" button to
display the captions.
Remember the "CC"
button is a toggle
button and by design a
click can enable or
disable the captions.
-
For the Show Caption
Speaker property,
click to change this
property to TRUE,
because we want to
display the speakers
from our captioning
text.
Remember there are
some captions that do
not require a speaker
name, because of this
you may not want to
view the speaker name.
This modifies how the
captions will display.
-
For the Use Default
Caption Button, make
sure the value is set
to TRUE for this
tutorial.
Note: Designers may
want to use a custom
closed caption button
for their Flash movie.
If this is the case,
set this property to
false. Remember to
define the symbol that
you will be using for
your own caption
button.
-
For the Caption
Control Button field,
leave it empty, as we
are using the default
caption button and not
a custom one. If you
were using a custom
button, you would
enter a reference to
the instance of that
symbol in this field
and would set the
Default Caption Button
property to FALSE.
-
For CC On Button Image
and CC Off Button
Image, leave these
fields empty also.
These fields are used
if you wish to display
a symbol for the
closed captioning
button, while the
captioning is playing
or not playing. To use
these, enter the
symbol linkage
identifier name of the
symbol in this field.
These properties are
associated with the
default caption button
only.
-
Caption Button X
Position and Caption
Button Y Position are
used to determine
where the captioning
button will appear.
The location of (0,0)
is based on the top
left corner off where
the viewer was placed
on the Flash stage as
shown in the
crosshairs symbol.
Positive values for X
and Y move the button
to the right and down
respectively, while
negative values move
the button position to
the left and up
respectively. In our
example here, we have
leaving the default
position as (0,0). In
the picture below, the
Hi-Caption viewer
control is displayed
below the movie file,
with the control
aligned to the lower
left of the movie.

-
Set the Caption Button
Foreground Background
Color to #000000 and
set the Caption Button
Background Color to
#FFFFFF, which will
create a white button
with black text. You
can use other colors
if you choose instead
of the defaults
mentioned here.
Click in the value
column top open the
color chooser control
where colors can be
selected. Leave the
Caption Button
Background Alpha set
to 0. This is a
transparency value
where 0 is fully
transparent, and 100
is not transparent.
-
For Use Default
Captions Text Box, set
this to TRUE. If you
set it to false, you
will need to provide
your own dynamic text
field in the following
property named
Captions Text Box.
-
There are various
fields to set the
appearance of the
captioning text. These
include Captions Text
Box, Captions Font
Name, Captions Font
Size, Captions Font
Color, and Captions
Background Color. For
this example, we will
leave these as
default. Alpha
Captions Background
and Background
Captions Alpha relate
to allowing
transparency of the
background of the
captioning text.
Leave these as default
in this example.
-
If
you wish to have a
border around your
default captioning
box, set Border
Caption Text to TRUE.
-
The height and width
as measured in pixels
of the captioning area
are controlled by the
Caption Area Height
and Caption Area Width
fields. In this
example, set them to
60 and 320
respectively.
-
Where the captioning
text appears in
relation to the top
left of the Hi-Caption
viewer is controlled
by the Caption Area X
Position and the
Caption Area Y
Position. Positive
values for X and Y
move the captioning
text to the right and
down respectively,
while negative values
move the captioning
text position to the
left and up
respectively. In our
example here, we have
leaving the default
position as (0,22).
Setting Up the Captions
in the Component
We
have added the
Hi-Caption viewer
component to the Flash
File and have set up the
display properties. Now
we are going to set up
the component to use the
captions you have
created. The Hi-Caption
viewer component can
either load the captions
directly from the
Hi-Caption XML file when
it plays or it can use
preloaded captions
stored directly in the
component instance. Both
methods are described
below.
Using Preloaded Captions
Follow the steps below
to preload the captions
into the component
instance:
-
Select Window | Other
Panels | Hi-Caption
Captions Loader from
the menu. This will
open the Hi-Caption
Captions Loader panel.
-
In
the edit box provided,
enter the full file
path and name of the
XML file that you
saved when creating
the captioning. The
default name would
have been dav02.xml.
-
For the Language Class
Identifier, enter
ENUSCC as the value.
This is the value of
the class that was
used in the original
captioning file in
Hi-Caption, except
without the . prior to
the name.
-
Select the Load All
(for the "Use
Preloaded Captions"
parameter) option from
the Captions Preload
Option drop-down.
-
Make sure that you
have the Hi-Caption
viewer component
instance selected on
the stage and press
the "Load the Captions
from the XML" button.
-
When this is completed
you will see the
following message
-
The following
parameters for the
selected Hi-Caption
viewer component
instance will be
populated
automatically:
-
Use Preloaded
Captions - will be
set to true
-
Buffer Initial
Captions - will be
set to true
-
Buffered Start
Frames for Language
1 - will be
populated with the
start frame numbers
from the caption
file
-
Buffered Speakers
for Language 1 -
will be populated
with the speakers
from the caption
file
-
Buffered Captions
for Language 1 -
will be populated
with the captions
from the caption
file
-
Language Class
Identifiers - will
have the value
ENUSCC
-
The captions are now
loaded directly in the
component instance and
you do not need to
distribute the caption
XML file with your
Flash file.
-
When done with the
properties, save your
project in Flash, then
from the Control menu
in Flash, select Test
Movie. Test your
movie to make sure
that the captioning
appears and that
everything works as
designed. When
distributing your
Flash file, if you
have chosen not to use
the preloaded
captioning option,
include the XML
captioning file with
it.
Using Captions directly
from the Hi-Caption XML
file
Follow the steps below
to enable the flash
movie to use the caption
file you created in the
previous section of this
tutorial:
-
The first component
property we will
modify is the
Hi-Caption XML File.
In this field, enter
the name of your XML
file that you saved
when creating the
captioning. The
default name would
have been dav02.xml.
Note: If you do not
enter a value for this
field, then the
Hi-Caption viewer will
look for an XML file
with the same name as
your Flash file, but
with the XML
extension. When
distributing or
testing your final
Flash file, the XML
captioning file needs
to be in the same
folder as your Flash
file.
-
Since the captioning
is stored in the
accompanying captioning
XML file for the Flash
file, the XML file
will need to be
downloaded by the end
user's system in order
to be loaded.
Depending on the size
of the captioning,
this may cause a delay
in display. You have
the option of
buffering the initial
captions to compensate
for this delay. In our
example here, we will
set the Buffer Initial
Captions property to
TRUE.
-
If
you have set Buffer
Initial Captions to
true, then you can
buffer up to 4
starting frames in
your captioning
presentation. The
next 8 steps are for
preloading the first 4
captions from your
captioning file
automatically. This
is the recommended way
to load captions for
buffering, however,
you can also enter the
information manually.
To enter the
information manually
proceed to Step 12.
-
Select Window | Other
Panels | Hi-Caption
Captions Loader from
the menu. This will
open the Hi-Caption
Captions Loader panel.
-
In
the edit box provided,
enter the full file
path and name of the
XML file that you
saved when creating
the captioning. The
default name would
have been dav02.xml.
-
For the Language Class
Identifier, enter
ENUSCC as the value.
This is the value of
the class that was
used in the original
captioning file in
Hi-Caption, except
without the . prior to
the name.
-
Select the Load First
4 (for the "Buffer
Initial Captions"
parameter) option from
the Captions Preload
Option drop-down.
-
Make sure that you
have the Hi-Caption
viewer component
instance selected on
the stage and press
the "Load the Captions
from the XML" button.
-
When this is completed
you will see the
following message
-
The following
parameters for the
selected Hi-Caption
viewer component
instance will be
populated
automatically:
-
Buffer Initial
Captions - will be
set to true
-
Buffered Start
Frames for Language
1 - will be
populated with the
start frame numbers
from the first four
captions in the
caption file
-
Buffered Speakers
for Language 1 -
will be populated
with the speakers
from the first four
captions in the
caption file
-
Buffered Captions
for Language 1 -
will be populated
with the first four
captions from the
caption file
-
Language Class
Identifiers - will
have the value
ENUSCC
-
Use Preloaded
Captions - will be
set to false
-
The first four
captions have now been
loaded directly in the
component instance and
it is setup to use
buffering. Proceed to
Step 17.
-
The next 4 steps are
for entering the first
4 buffered captions
manually.
-
If
Buffer Initial
Captions is set to
true, then the
captioning which will
be buffered will be
associated to frames
in the Flash
presentation. If you
imported your movie
file at 12
frames/second for
example, then for
every second that goes
by, the Flash file
moves 12 frames.
Click on the Buffered
Start Frame for
Language field and
enter up to four
starting frames to
display captions from
the buffer. In our
example here, we are
entering the values of
1, 89, 111 and 136,
based on our 4
starting frames times
as displayed in
Hi-Caption.
-
If
you have set Buffer
Initial Captions to
true, then click in
the Buffered Speakers
for Language and enter
up to four speakers
for the captioning.
In our example here,
we are entering
Narrators as the
speaker in all 4
instances.
-
If
you have set Buffer
Initial Captions to
true, then click in
the Buffered Captions
for Language and enter
up to four blocks of
text for the
captioning.
-
For the Language Class
Identifier, enter
ENUSCC as the value.
This is the value of
the class that was
used in the original
captioning file in
Hi-Caption, except
without the . prior to
the name. Adding a
valid class name to
this field is crucial
to having the
captioning appear in
Flash.

-
When done with the
properties, save your
project in Flash, then
from the Control menu
in Flash, select Test
Movie. Test your
movie to make sure
that the captioning
appears and that
everything works as
designed. When
distributing your
Flash file, if you
have chosen not to use
the preloaded
captioning option,
include the XML
captioning file with
it.
Tips for using the
Hi-Caption viewer with
linked FLV files
(The MediaDisplay and
MediaPlayback components
are only available with
Flash MX 2004
Professional)
The
Hi-Caption viewer
Component for Macromedia
Flash allows you to show
captions for a flash
video (FLV) that is
being displayed in
either a MediaDisplay or
MediaPlayback component.
This is done by
"hooking" the Media
component to the
Hi-Caption viewer.
Follow the steps below
to use this
functionality:
-
With a flash file open
that has either a
MediaDisplay or
MediaPlayback that
loads an FLV file that
has been captioned
using Hi-Caption SE,
add and setup a
Hi-Caption Viewer
component to the file
as shown in previous
sections.
-
In
the ActionScript for
the flash file, add
the following line of
code:
InstanceName.HookMediaComponent(myMedia);
where: InstanceName is
the name of the
Hi-Caption viewer
Component assigned by
you in the instance
field and myMedia is
the name of media
component.
-
The Hi-Caption Viewer
will hook the media
component and do the
following:
- Remove all existing
CuePoints from the
media component
- Add CuePoints for
each captioned frame
using the addCuePoint
method with the Frame
number as the cuePoint
name and the following
calculation as the
Timing:
Math.ceil(FrameNumber
/ aMedia.fps )
- Set a cuePoint event
listener that will set
the caption text based
on the cuePoint name
-
To
remove the reference
to the media
component, simply use
the following line of
code:
InstanceName.UnHookMediaComponent();
where: Instance Name
is the name of the
Hi-Caption viewer
Component assigned by
you in the instance
field.
Tips for using the
Hi-Caption viewer with a
Slider
One
of the more common
things that a flash
interface allows users
to do is to change the
position of the movie
being played using a
slider control (or
something simliar). The
Hi-Caption viewer
component will display
the proper caption if
the user sets the
position of the movie to
a captioning point,
however, it is more
likely that the position
of the movie will be
between 2 captioning
points. To make the
Hi-Caption viewer
Component display the
caption for the closest
captioning point follow
the steps below:
-
With a flash file open
that has a Hi-Caption
Viewer component and a
slider control.
-
In
the ActionScript for
the slider control
that executes once the
new frame of the movie
is known, add the
following line of
code:
InstanceName.setCaptionClosestToFrame(myNewFrame,
bShowFirstEarly);
where: InstanceName is
the name of the
Hi-Caption viewer
Component assigned by
you in the instance
field, myNewFrame is
the frame number that
was moved to and
bShowFirstEarly is a
Boolean value that
controls what happens
if the frame number is
before the first
caption.
The value of
bShowFirstEarly should
be true if you want
the first caption to
be shown when the
frame is before the
first captioned frame,
if you exclude this
parameter or pass a
value of false, then
the caption text will
be set to a blank
string when the frame
is before the first
captioned frame.
Tips for using
multiple languages
The
Hi-Caption viewer
Component for Macromedia
Flash allows you to
switch languages in code
(on the fly) during the
caption display. This is
done by using
ActionScript to access
the
SelectedLangStyleName
property of the
Hi-Caption viewer
Component. Note the
value that you are
setting the
SelectedLangStyleName
property value to must
be in the language ID
List. Additionally the
component will, by
default, define the
property to be the first
item in the list if you
have not set this
property.
InstanceName.setSelectedLangStyleName(
val );
where: Instance Name
is the name of the
Hi-Caption viewer
Component assigned
by you in the
instance field and
val is equal to a
language id code
from the Language ID
list.
-
Remember that
Hi-Caption SE allows
for the editing and
creation of multiple
languages for the same
captioning file. There
are some important
things to remember:
-
If
you are using
languages other than
English you should
save your XML in
Unicode format. To
change the format,
check or uncheck
Generate Unicode XML
from the Settings menu
in Hi-Caption.
-
Because the XML File
size can impact the
performance of the
caption display
because it has to load
the whole file you
should use a single
XML Captioning file
for each language
(Though this is not
required.) If you do
this simply call the
InstanceName.setHiCaptionXMLFile(
val ); function to use
ActionScript to change
the caption file.
-
Do
not use online
translation tools to
convert to another
language, the
translations are
rarely 100% accurate
to the meaning
-
NOTE: The Use
Preloaded Captions
option only supports a
single language (the
first language in the
list). If you are
using this option then
you will have to add
some additional
ActionScript to turn
the option off and
load the Hi-Caption
XML File. You will
also need to include
the Captioning XML
file when distributing
your Flash. The
ActionScript to
perform this would
look something like
this:
InstanceName.usePreLoadedCaptions
= false;
where: Instance Name
is the name of the
Hi-Caption viewer
Component assigned by
you in the instance
field.
Some Caption Tips
for the Flash Designer
The
following are general
Closed Caption
guidelines that should
be followed, check the
other resources section
of this tutorial for
more information:
-
Captions that are two
or more lines should
be left aligned
-
In
general, you should
not exceed three lines
of captions
-
Captions should be at
the bottom of the
Flash movie
-
Follow standard
capitalization and
punctuation rules
-
Italics should be used
for Emphasized words
and several other
instances. Please
review a captioning
guidelines document
for more information
on the use of italics.
Remember the
Hi-Caption program
will allow you to
enter HTML Tags and
will escape them out
as necessary when
writing the XML
Caption File.
For information on
what HTML Tags are
available in the Flash
player visit the
Macromedia Web Site.

-
Emotion and Tone
should be conveyed
with punctuation marks
(i.e. use multiple
explanation marks for
strong emotion. )
-
Sound effects or off
screen effects should
be noted, e.g. [jet
engine roar]
-
Keep the captions
synchronized to the
video
-
It
is a good practice to
not spell out numbers
(use 50 not Fifty)
-
Use colors smartly
with good contrast to
make the captions easy
to read
-
Any captioning credits
should go at the end
of the movie
