WebVTT ruby annotations: retain reading text without changing dialogue
A WebVTT ruby annotation associates reading information with base text; it is not automatically another spoken word. A simplified caption export can lose or flatten that relationship. Preserve the original authorized cue, identify the intended annotation and test the receiver before treating every extracted text token as dialogue or accepting a plain-text replacement.

Identify base wording and reading information
Read the cue against the matching recording and source context. Distinguish the displayed name or term from an accompanying reading intended to help pronunciation. Ask the authorized supplier about an unclear association rather than silently choosing the annotation as the spoken wording.
Keep the resource’s exact version and cue interval. A pronunciation note can be meaningful without being part of a verbatim transcript. Record whether the recipient needs styled selectable text, a simplified reading aid or a faithful dialogue record; each requires a different interpretation of the same supplied annotation.
Inspect the native WebVTT structure
WebVTT caption cue text permits ruby and ruby-text markup. The ruby element groups the base text and associated rt reading content. This is cue structure, not a command to translate the soundtrack or infer pronunciation for a language the source did not annotate.
Inspect that association in a trusted text editor before conversion. Keep the permitted tags and cue timing in a retained copy. Removing all markup by a generic text operation can join base and reading text together in a way the author never intended as a sentence. Do not repair the result by guessing missing wording from the filename.
Verify annotation presentation in the intended receiver
Load the exact caption resource with the matching video and inspect a cue containing the annotation. Check whether the base text remains readable, the reading is associated with the right portion and nearby content is not obscured. Observe ordinary playback and a representative small display where that delivery matters.
A player can preserve the words while simplifying presentation, so record what was actually observed. A successful parse or an enabled text track does not certify readable annotation placement. Compare with the known source presentation and ask for a supported alternate resource when the receiver cannot provide the intended relationship.
Review a simplified export as a separate editorial artifact
When conversion to SRT or another simpler resource is required, inspect the actual result cue by cue where annotations occur. Decide explicitly, within authorization, whether reading information should be omitted, explained separately or retained in a clearly marked form. Do not imply that a converter automatically makes that editorial decision correctly.
Keep the styled parent, selected derivative and explanation of what changed. Verify wording, timing and the receiving presentation independently. SocialVidDownloader does not generate pronunciation annotations, translate captions or promise arbitrary WebVTT ruby conversion through its local subtitle tools. Leave unexplained joined text or lost required reading information unapproved instead of calling a plain text export a complete styled handoff.
Worked example
Example: a supplied name has a ruby reading above its base characters. A plain-text export concatenates both strings and appears to add words to the speaker’s sentence. The reviewer preserves the original association and approves only an explicitly reviewed simplified version rather than treating the concatenation as a verbatim transcript.
