Do sample-library demo videos need transcript notes as well as captions?

[ethanjamescolez]

A KVR forum thread with an embedded sample-library demo video exposes the usual video controls around captions, subtitles, settings, speed, and transcript. That raises a practical documentation question for sampler, sample-library, and soundware demos. https://aiyoutubetranscript.com/

For tutorial or demo videos, I would separate these formats:

1. Captions help while watching.
2. TXT transcript notes help users search feature names, parameter names, setup steps, and version details.
3. SRT or VTT remains the timed subtitle handoff.
4. Generated text needs manual checking because product names, preset names, and technical terms can be wrong.
5. A forum post should use a concise summary instead of pasting a full transcript.

For KVR sample-library demo threads, where do transcript notes help most: below the video, in product docs, in release notes, in accessibility notes, or only as private drafting material?
