Create a descriptive transcript from authorized caption text
A descriptive transcript presents the meaningful speech, sound, and visual information from a recording as readable text. Reviewed captions can supply part of that text, but they often assume the reader can see the picture. Build a separate companion that communicates necessary visual context, then check it without relying on video playback.

Check what the caption text leaves to the picture
W3C’s transcript guidance distinguishes basic audio transcripts from descriptive transcripts that also convey important visual information. It explains that caption text can be a starting point, with necessary picture information added. Keep the source recording and the reviewed caption version associated before beginning this separate document.
Consider an instructional recording where the speaker says, “Choose this setting,” while pointing at one of three controls. The words alone do not identify the setting. In your working notes, mark that passage as requiring visual context, and record the actual control shown rather than guessing from the caption sentence.
For a second example, a silent demonstration can show a device changing from a red indicator to a green one. If that transition explains whether a step worked, capture its meaning in the transcript even though speech recognition would supply no corresponding sentence. Decorative movement that adds no information need not become a long narration.
Create a readable document without presenting additions as speech
Keep an untouched copy of the caption resource, then work on a separate transcript document. W3C suggests grouping caption lines into useful paragraphs, identifying speakers where needed, and making the transcript easy to find. Use those principles for readability rather than preserving every timed cue as an isolated line.
In the hypothetical settings demonstration, a reviewed transcript could separate the spoken instruction from a clearly labelled visual note: the presenter selects the control named Notifications. This is added context, not a quotation of words that were never spoken. Keep the label consistent so a reader can distinguish dialogue from your description.
Do not replace an uncertain label with an invented instruction. Pause the source, enlarge the relevant view if appropriate, and ask the creator to confirm illegible text. Maintain an unresolved-items note until that context is established. A fluent paragraph can still be inaccurate when it silently supplies missing facts.
Verify the transcript as a reader-only companion
Ask a reviewer to follow the hypothetical procedure using the text alone. Can they identify the selected control, the expected indicator change, and the next action? Compare any question they raise with the actual recording. This check tests information completeness for the described task rather than whether the document merely resembles a polished article.
Then review against the video again for errors introduced during restructuring. Check numbers, speaker attribution, omitted conditions, and visual notes that could be confused with spoken advice. For sensitive instructions, have the appropriate content owner review the wording. Preserve unresolved questions instead of describing an unreviewed section as verified.
A descriptive transcript is not automatically a caption track with usable timestamps. If an editor also needs synchronized captions, keep that resource separate and test its timing through the caption workflow. Changes to a reading document should not silently overwrite the only reviewed timed-text file.
Deliver the companion with the correct recording version
Place the transcript or a clear link close to the recording in the authorized delivery environment. Check that the reader can open it and identify which recording it describes. A document for an earlier edit may include removed scenes or miss new instructions, so include useful version context without exposing unnecessary personal information.
For a handoff, retain the original caption file, the descriptive transcript, and a brief record of reviewed additions. In our hypothetical demonstration, the visual notes about the Notifications control and indicator transition should remain associated with the edit where those details appear. If the interface later changes, revisit those notes rather than assuming that unchanged spoken words make the transcript current.
SocialVidDownloader does not generate this companion, transcribe recordings, or export captions. This is a creator workflow for independently obtained authorized material. Use the automatic-caption review guide to check generated text and the descriptive-audio guide when the required companion is spoken narration instead of a readable document.
Worked example
In a hypothetical tutorial, captions say “Select this, then wait until it changes.” The picture shows the Notifications control and an indicator turning green. A reviewed descriptive transcript retains the speech and adds clearly labelled visual context identifying both details. A reader-only review checks whether the instructions can be understood without guessing at the unseen pointer.
