Captions versus subtitles: choose for language and accessibility
Choose text by the information your audience needs, not only by the label in a player menu. Captions normally convey speech plus meaningful non-speech sound; dialogue subtitles may focus on translation. Terminology varies by region. Inspect the actual text before assuming that a selected language makes a recording accessible without sound.

Choose for the viewing task
A viewer who understands the spoken language but cannot hear the recording needs more than translated dialogue. Speaker changes, an off-screen alarm, laughter that changes the meaning of a response, or relevant music can carry information. A dialogue-only transcription can omit those details.
A viewer who hears the sound but does not understand the dialogue may primarily need translation. Those needs can overlap: a translated caption track can also represent meaningful sounds. Check content and language independently. A menu called Subtitles can contain accessibility captions, and a menu called Captions can include incomplete automatic text. The label alone is not a quality certificate.
Check a scene that depends on sound
Review a short scene where more than one speaker talks or a sound affects the action. Compare the text with the actual recording. Ask whether a viewer relying on text could identify who spoke and understand the important event without inferring it from missing sound.
Do not require a description of every background noise regardless of relevance. The useful question is whether the sound contributes to understanding. Keep speaker identification readable and consistent rather than adding invented names. For an unfamiliar language, use a competent review process instead of assuming a machine-produced translation preserves every instruction or proper noun. Listening and language understanding are separate checks.
Understand how the text is delivered
Caption content can be separately selectable, stored in a sidecar, or visibly embedded in the pictures. That delivery choice determines whether the viewer can turn it off, resize it, or select another language. It does not by itself establish whether the wording includes non-speech information.
A transcript is another useful form, but an untimed document is not automatically synchronized captions. When retaining an authorized recording, note which text resource belongs to it and which version was reviewed. An edited video may no longer align with an earlier caption file. Keep content quality, timing, and delivery format as separate review decisions.
Check the downloader boundary
SocialVidDownloader selects real source video and audio. Its current public workflow does not offer a subtitle-export selector or promise that every caption shown by the source player appears in a downloaded file. An alternate audio language is also not a caption track.
After saving, inspect the local player for actual text tracks and test what it displays. If the source's text overlay is absent, that may be a delivery difference rather than lost video pixels. Where you need captions, obtain an authorized resource from the creator or supported platform controls. Do not label a silent viewing copy accessible merely because a subtitle menu existed on the original page. The relevant result is the text actually available to the intended viewer.
Worked example
Illustrative review: an instructional clip shows a machine while an off-screen speaker says to stop when an alarm sounds. Dialogue translation alone may show the spoken sentence but omit the alarm event. A reviewed caption track identifies the relevant sound and speaker; neither choice changes the audio recording or grants permission to redistribute it.
