  • We received funding to caption more than 200 existing videos on YouTube’s Purdue Channel.
    While doing those videos, YouTube made Machine Transcription available for free.
  • 16 videos in the test
    Lengths varied (2min to ?mins), background noise varied, in-studio and out of studio recordings
  • AST cost $162/hr for transcription and captioning file
  • Unexpected Benefit of captioning all of those YouTube videos
    They are pulling YouTube video from the Purdue Channel
  • Fears were unfounded. They already had a system in place for captioning TV shows of the football and basketball coaches.
    The video production group and the webcast group got together and worked out how to transfer the live captions from the TV telecast to the webcast.
    Registrar’s Office said they had been wanting to provide captioning for years

    1. 1. Getting Captioning Started on Campus: Lessons Learned Dean Brusnighan Assistive Technology Specialist Purdue University
    2. 2. Background • A one-year, campus-wide, proof-of-concept project • Provide captioning in broad categories: • Administrative video • Academic video • Intercollegiate Athletics
    3. 3. Agenda • YouTube • Commencement Ceremonies • Echo 360 • Intercollegiate Athletics • What I learned
    4. 4. Administrative Video
    5. 5. YouTube • Set up a test to compare costs: • fixing machine transcription vs. • paying a captioning vendor (Automatic Sync Technologies)
    6. 6. 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
    7. 7. 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
    8. 8. What I Learned #1 • A captioning vendor can be a better solution than alternatives in some cases.
    9. 9. 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
    10. 10. Administrative Video
    11. 11. 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
    12. 12. What I Learned #3 • New collaborations to provide captions can come from unexpected places.
    13. 13. Academic video
    14. 14. Echo 360 • Lecture capture system • Business relationship with AST allows automated submission of each lecture recording • Waited for an opportunity where captioning was needed
    15. 15. 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
    16. 16. Echo 360 Captions
    17. 17. What I Learned #4 • Ask questions of vendors and look for built-in collaborations to provide captioning.
    18. 18. Intercollegiate Athletics
    19. 19. 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?
    20. 20. 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
    21. 21. 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
    22. 22. 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
    23. 23. 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.
    24. 24. What I Learned Recap 1. A captioning vendor can be a better solution than alternatives in some cases. 2. Providing captions in one area can lead to unexpected benefits in another area 3. New collaborations to provide captions can come from unexpected places. 4. Ask questions of vendors and look for built-in collaborations to provide captioning. 5.
