1 Jayme Johnson ◎ AHG 2012 Captioning Web-based Digital Media

2 Presentation Overview  Definitions  Captioning & accessibility basics  Digital video formats  Captioning concerns  Overview of captioning tools  Process overview

3 The Most Important Thing If you can pay someone else to do your captioning... DO IT!!!

4 Definitions Open vs. Closed Captions Subtitles vs. Captions Line 21 & Decoders vs. Digital Roll-up vs. Pop-on SAMI & SMIL Quicktime Text? Streaming media vs. Static Media

5 Captions vs. Subtitles Captions Can be turned on or off Must have decoder in system—will work with Windows Media Player Follow Line 21 standards Text-based White text on dark background Roll-up or pop-on Subtitles Can be turned on or off Must have menu option—will work on any system Just another digital track Text-based or image-based No background (can choose fill and stroke for letters)

6 Captioning in General Use two lines Left-align the two lines If speaker leaves screen, can move captions to that side Can identify speaker on a separate third line 32 characters/line max Sans serif font (Helvetica, Arial, etc.) Prefer upper- and lower-case letters Transcribe dialogue word for word, but do not include “nonsense syllables”

7 Line Division is Critical! Keep modifier with word it modifies Keep prepositional phrases together Keep a person’s name and title together Break lines before conjunctions (FAN BOYS) Keep auxiliary verb ( can, have, will ) with the word it modifies Break captions at the end of a sentence

8 Presentation Rate Allow a minimum of 1.5 seconds duration for each 32 characters of text. Allow a minimum of two seconds duration to display the last 32 characters of text before blanking or moving captions. Do not display any caption for less than one second. The maximum presentation rate should be three seconds duration for each 32 characters of text. From http://www.cfv.org/caai/nadh20.pdf

9 Italics Use for voice-over reading Off-screen dialogue, unless entire video is narrated Dreaming, thinking, etc. Background audio: PA system, etc. Foreign words Emphasis

10 Sound Effects Include important sounds Use description (in brackets) and onomatopoeia Italicize if off-screen Lowercase Sustained sounds use present participle (-ing) Be as precise as possible

11 Music Use descriptions that indicate mood Caption lyrics verbatim Include name of vocalist/group and song title in brackets Put musical notes around lyrics (leave space) When no lyrics or cannot use, describe

12 Legal Issues Unless your campus owns the copyright, must get permission To caption To change format (VHS to DVD; DVD to Web) Copyright vs. Accommodation

13 Section 504 vs. 508 Section 504 Deals with accommodation Providing access for individual students Requires captioning on request Section 508 Deals with access Providing access for all students Requires captioning before video is first shown in classroom

14 DSPS Role DSPS may focus on accommodations or assist with general access New materials fall under Section 508 - Institutional Requirement Purchase captioned materials Caption before first use Purchasing department responsible for cost of captions
