Using Timestamps Selectively in Transcripts

Using Timestamps Selectively in Transcripts records a distinct W3C-supported accessibility writing task while keeping implementation mechanics and unsupported house-style rules outside the guidance.

Quick answer

Include timestamps in a transcript only when they are useful; they usually do not need caption-level granularity or end times.

Important caveats

Scope Boundary

W3C presents timestamps as an optional usefulness feature, so do not force them into every transcript.

Further guidance

Content

Add time markers where they help readers locate material in the media, and omit dense timing data when it would mainly create clutter.

Purpose

Selective timestamps preserve navigation value without turning the transcript into a caption-file display.
