Adobe Premiere Pro CS5 can convert an audio fi le
containing speech to a text transcription fi le. Then
you can search the audio fi le for keywords, mark
the In
and Out points of your clips, and even locate
a specifi c video frame using a text search tool. New
is the ability to detect faces in your clips so you can
more quickly fi nd clips with faces in the Project panel.

Getting started
Although it may not be obvious from the small sample files used in this lesson,
speech transcription can be a huge time-saver, allowing
you to do text searches to
find precisely the video frame in which a specific word is spoken. You can easily
add markers or edit points after using this feature to locate keywords. Without this
feature, you would need to scrub or play the audio of the file to listen for keywords.
You’ll notice that it takes some time for Adobe Premiere Pro CS5
to transcribe an
audio file to text. But this process can run in batch mode in the background while
you do other work. It’s also worth noting that once the transcription occurs, the
transcribed text becomes part of the audio file’s metadata.
Even if you export the
file, the transcription will remain with the file.
