>> Hello. Welcome back to our podcast captioning tutorial.
This segment is about captioning specifically
for Apple devices using QuickTime Pro.
Apple has recently announced specific captioning support for QuickTime,
iTunes, all of the current iPods, and the iPhones.
The general process for captioning specifically for Apple devices is
to generate your source video, which is likely an MOV file,
then generate your caption file which is an SCC file,
and then convert your source media to M4V format,
and embed the caption data using Compressor 3.
Compressor 3 is an Apple product that runs only on Macs,
and is shipped only with Final Cut Studio Pro.
Final Cut Studio Pro is an expensive product,
so this can also be accomplished using QuickTime Pro, but only on the Mac.
First you need to get a free plug-in component for QuickTime.
Go to developer.apple.com/samplecode/ closedcaptionimporter.
Download the DMG file and copy Closed Caption Importer component
from the DMG file to /Library/QuickTime.
Once you have QuickTime Pro installed, and have downloaded
and installed the closed caption importer component, we are ready to go.
Let's take a look at the process
to incorporate the SCC caption data using this method.
In many ways this method is very similar to the open captioning process
that we covered in an earlier tutorial.
We are essentially going to open our SCC file in QuickTime,
and copy it into our movie.
The key to success here is that you need
to perform all format conversions before you incorporate the caption data.
This sequence is important.
If you incorporate your caption data and then convert your MOV file
to the M4V format, the captions will get lost in the conversion.
So let's start by loading our source movie into QuickTime.
Now go to the Window menu and select the Show Movie Properties.
Next, click the video track, and click the visual settings tab.
Size the movie for the iPod, which is 640 x 480.
And center, and center if it is necessary.
Next, we need to convert this to iPod format.
Under the File menu select the Export option,
and then select the Movie-to-iPod export function.
Save your file.
This will create an M4V file.
Once this is done, exit this movie, and pull up our new M4V in QuickTime.
Now we can add the captions.
Open the SCC file in QuickTime as well.
You can actually play this caption track and watch the captions appear.
But instead, let's use command-A to select all of the captions,
and then command-C to copy it.
Now go back to our main video, and ensure the play head is right
at the beginning of the file.
Now use the Add-to-movie function under the Edit menu
to paste our captions into our movie.
Now reset the play head, and check the view menu
to ensure the captions are turned on.
Now play our movie, and we should see the captions appear.
>> Hello. I'm going to show you how easy it is
to use Automatic Sync Technology's CaptionSync -
>> Good. Finally, save your movie, under the file menu choose save.
QuickTime will write out your final movie as an MOV file again.
But don't worry, when you load it into iTunes you will be able to sync it
to your iPod without further conversions,
and the captions will appear in both iTunes and your iPod.
The trick to making this process work is to first convert your movie
to the iPod format, and then add your captions and save the resulting file.
Do not rely on QuickTime or iTunes to convert the format to M4V file
after you've added captions, as this will lose the captions.
That's all there is to it.
