Create a descriptive transcript that conveys a video without its pictures

Distinguish captions from a descriptive transcript

Captions support following audio in time with a video, but they do not necessarily describe a chart or interface visible only on screen. A transcript of a presenter saying look at the right column cannot explain what that column contains. W3C WAI distinguishes a basic transcript from one that also conveys meaningful visual information. This article addresses that additional editorial task, rather than treating subtitle proofreading as sufficient. The intended result is text that lets someone follow the explanation without depending on the pictures or sound, while remaining faithful to the approved video.

Inventory information supplied only by the image

Review scenes for on-screen text, chart conclusions, meaningful actions and changes after an operation. Not every background color or decorative object needs description. Separate information necessary for understanding from decoration. For a bar chart, explain what is compared and the relevant relationship, not simply the colors of the bars. For a tutorial, name the control and resulting state rather than giving only its screen position. This inventory reveals where the existing speech assumes visual access. It should guide additions to the transcript without turning a practical explanation into an exhaustive catalog of every pixel in the video.

Use captions as a draft rather than the finished document

Caption text can be a starting point, but a long sequence of short lines and timestamps is often a poor reading experience. Identify speakers, rebuild paragraphs and insert necessary visual descriptions in context. Make it clear which words were spoken and which explanatory material was added by the editor. If disfluencies are simplified, preserve the speaker’s meaning and qualifications. Check product names and numbers against the approved source. An automatically generated transcript is a draft to review, not an accepted description of the final video merely because it arrived as an export from the editor.

Check diagrams and procedures through the text alone

After adding visual information, read the text independently and ask whether it supports the same conclusion. A price comparison needs the plan, currency, billing period and qualifications, in prose or an accessible table. Include an essential qualification even if it appeared only briefly in the video. Describe interface procedures through control labels and purpose rather than screen coordinates. Do not introduce an unsupported conclusion while improving readability. If an additional explanation is needed, distinguish it from the original narration and obtain content review instead of presenting new editorial material as something the speaker already said.

Structure the reading experience

Organize the document with meaningful headings, paragraphs and lists so readers can navigate to a relevant section. On a publishing page, verify that headings are represented structurally rather than only styled as large text. Give links names that explain their destination instead of using here without context. Avoid replacing the transcript with an image of text. Place a clear transcript link or accessible section near the video so that someone who chooses not to start playback can discover it. The document’s usefulness depends on both the completeness of its content and the ability to find and navigate that content.

Review navigation and alternative reading methods

Alongside factual review, check keyboard access to links and navigation through headings. Where appropriate, use a screen reader to assess speaker changes and relationships in tables. Success with one tool does not prove conformance in every environment or against every applicable requirement. When a reader reports a missing explanation, decide whether the correction belongs in the transcript alone or also in the video. Captions, descriptive text and audio description serve different needs; creating one resource does not automatically remove the need for another. Record the scope of the checks actually performed and any remaining issue.

Maintain the text with the video release

When a video changes, identify the dependent transcript passages. Prevent a removed scene from remaining as text or a revised price from leaving an obsolete written figure. Link the content revision, publication date and corresponding video location in the release record. Retain an editable source that supports targeted updates rather than recreating the entire document blindly from each new export. Completion means more than a transcript file existing. The published text should convey the approved video’s information in a usable form, and another editor should be able to determine which text belongs with the current release.
