What Makes a Video Accessible, and to Whom
An accessible video is not one feature but several, each serving a different person. Captions serve someone who cannot hear the audio; audio description serves someone who cannot see the screen; sufficient contrast and a keyboard-operable player serve people the first two do not reach. Meeting one requirement is not meeting the standard.
Content teams usually add captions, treat the job as done, and are surprised by an audit. The gap is not effort but scope: each requirement addresses a distinct barrier, and covering three of four leaves the fourth group with no route into the content at all. What belongs in the file rather than the frames is audit findings and remediation backlogs: they identify which properties currently fail and are the material a complainant would most like to have.
The template covers it in nine scenes: one on the four barriers and who each affects, two on captions and what distinguishes usable ones from automatic ones, two on audio description and when it is required, one on contrast and text size, one on player controls and keyboard operation, one on the checks to run before publishing, and one on documenting what was done.
