RE: [Avid-L2] Script-based editing and production

While I haven't used it I was very impressed with what premiere pro does in
this vain.

As far as I could tell you could give it an audio clip and it would
transcribe it for you and from there you could do anything with it like
search etc.

If you think of documentary makers where they are editing material that
wasn't scripted then that's why you would use it. So at the moment people
get someone to manually transcribe the video footage and assign timecodes
against it. Then they often go away and construct their story on paper
before actually starting the proper video edit. So to be able to combine
these steps and have the transcription attached to the video would be useful
I would say. Then all the searching for things you remember would be much
easier etc.

Subject: [Avid-L2] Script-based editing and production

I recently sent some questions to the group regarding the potential value
that pure audio search would bring to video editing and production software
similar to the tools offered by Avid, Adobe, Apple, etc.

I'd like to share another example of how ScriptSync could be useful, and get
feedback on other ideas that you have for making use of Nexidia technology.

First, a basic overview of how this works. ScriptSync, at its core,
leverages Nexidia's phonetic search technology to locate groups of words
within an audio file. These words are derived from shooting scripts and
transcripts in the case of Media Composer. Because ScriptSync can locate any
group of words within any audio file(s), the text does not have to cover all
the words spoken in the audio (similarly, the text could cover much more
than that audio). The resulting output is a word-for-word time alignment (to
the millisecond) of the words from the text that are found in the audio.
Extra words are not assigned a time (no artificial forced-alignment).

MSNBC leverages both transcripts and closed-captions to produce a text index
of each word spoken in their television shows. For an example of how they
leverage this feature, see -- http://www.msnbc.msn.com/id/27721638/.
<http://www.msnbc.msn.com/id/27721638/> (select "Play", watch the
commercial, the select either `transcript' or `clip and embed' mode in the
player controls).

For each inaugural address (since the 1930's), the video has been sync'ed
with the audio. The end user can select any group of words in the transcript
and the player will advance and play that exact portion of the audio. Text
can be highlighted and a virtual clip of the associated video is available
to be previewed and embedded externally. Relevant keywords have also been
pulled out of the text and located within the video - select any keyword
below the player and each instance of that word is displayed with a marker
along a timeline representing the video; each marker can be selected to
jump-to the word spoken in the video.

In addition to this consumer application of Nexidia technology, do you have
ideas on how ScriptSync would be valuable to the professional editing
community?

Would a text-based video editor - i.e., ability to select text, sequence and
re-sequence text segments, resulting in a modified scene sequence that could
be previewed as if it were a single edited video - streamline or otherwise
make your job easier?

Do you see applications of this technology in specific tasks or processes
you do while editing video?

How do you see this technology best delivered - as an application feature
where archived content accessible and can be sync'ed? As a service where a
text file and video(s) can be uploaded and processed?

Another note about MSNBC - they also use Nexidia technology to time align
all network programming with it's associated closed-captioning. The
closed-captioning is sometimes of poor quality and often broken into much
larger chunks that needs to be "filtered" using ScriptSync to identify only
that which is relevant to the program. The resulting time-aligned metadata
provides a foundation for rich keyword based search and browsing of topical
content on their website.
