FAQs for 1.2.2 Captions (prerecorded) (A)
Do videos need to be 508 compliant?
Videos used and distributed by the government must be 508-compliant. But for organizations that aren’t creating US government videos, 508-compliance still has value.
What makes a video ADA compliant?
Accessible videos have three main elements: Captions—The audio parts of your video appear as text at the appropriate time and give access to people who are hearing impaired or deaf. An audio description—A description of a video’s visual elements, gives access to people who are blind or visually impaired.
How are closed captions generated?
Closed captioning is either in a recorded (offline) format or live (in real-time). For captions to show up on your television screen at the right time, the captioning is embedded in the television signal and becomes visible when a special decoder built directly into the TV activates.
What is synchronized media?
Audio or video synchronized with another format for presenting information and/or with time-based interactive components, unless the media is a media alternative for text that is clearly labeled as such.
It helped when you mentioned that synchronized captions are important for a better outcome of the project. My cousin mentioned to me last night his friend is looking for a captioning service that can do accurate captioning solutions for their video formats and asked if I have any idea what is the best option to do. Thanks to this informative article and I’ll be sure to tell him that he can consult a quality transcription specialist as they can answer all his inquiries.
