Getting Captioning Started on Campus:Lessons Learned
Dean BrusnighanAssistive Technology SpecialistPurdue University
Background
• A one-year, campus-wide, proof-of-concept project• Provide captioning in broad categories:• Administrative video• Academic video• Intercollegiate Athletics
Agenda
• YouTube• Commencement Ceremonies• Echo 360• Intercollegiate Athletics• What I learned
Administrative Video
YouTube
• Set up a test to compare costs:
• fixing machine transcriptionvs.
• paying a captioning vendor (Automatic Sync Technologies)
Compare processes
Machine Transcription• Download MT file from
YouTube• Fix word recognition and
timing errors• Upload to YouTube
AST captioning vendor• Quickly review video to
identify problematic words or names• Submit video to AST• Review returned caption file
to fix errors, if any• Upload to YouTube
Compare costs
Machine Transcription• Editing time per video (avg):• 114 minutes
• Employee cost: • $8.50/hour
• Avg Cost per video: • $16.20
AST captioning vendor• Editing time per video (avg):• 31 minutes
• Employee cost: • $8.50/hour
• Employee Cost per video: • $4.47
• Avg AST Cost per video:• $8.01
• Avg Cost per video: • $12.48
What I Learned #1
• A captioning vendor can be a better solution than alternatives in some cases.
What I Learned #2
• Providing captions in one area can lead to unexpected benefits in another area
• Undergraduate Admissions now has captions on almost all of their online video content
Administrative Video
Commencement Ceremonies
• At Purdue, available on:• Local access cable TV• Simultaneous webcast
• What did I start with?• Fear of the unknown
• My fears were unfounded
What I Learned #3
• New collaborations to provide captions can come from unexpected places.
Academic video
Echo 360
• Lecture capture system• Business relationship with AST allows automated
submission of each lecture recording• Waited for an opportunity where captioning was
needed
Echo 360 (cont.)
• A distance education student needed captions in 2 classes• Collaboration with the IT unit in charge of Echo
360 was critical• Effort required to set up the “automatic”
submission• In 2 or 3 business days, the caption file was
returned & integrated into the recorded lecture• Student found the captions very helpful
Echo 360 Captions
What I Learned #4
• Ask questions of vendors and look for built-in collaborations to provide captioning.
Intercollegiate Athletics
Intercollegiate Athletics
• Ohio State case• Desire to caption the words of the PA announcer,
during the game and during breaks• Purdue Athletics explored potential for captions
on scoreboards• Not possible at this time
• Could captions be provided directly to mobile devices in sports venues?
Captions Using Twitter
• Challenging to keep posts below 140 character limit• Student testing showed that posts took about a
minute to show up• Too long for game captioning
Captions Using CoveritLive
• CoveritLive is a web based live blogging tool (www.coveritlive.com)
• No limit on number of characters in post• Posts show up in a few seconds on most web-
enabled mobile devices• Blackberry issues
• Season ended before student testing could be conducted in Spring 2010
Captions & CoveritLive (cont.)
• Athletic Dept very supportive of this project• Purchased 3 iPod Touches to loan to students
• Testing with students will begin soon• Blackberry issues continue
What I Learned #5
• When the obvious solution won’t work, it can lead to a more creative solution. It may be better than the obvious solution.
