1
Identify the source
Is the material a passage you wrote, a document you can access, or a video another creator published? A text-first approach starts with words you supply or select. YouTube starts with an existing upload, unless you are making a video yourself. If you cannot find the exact passage as a video, a related upload is not a substitute for hearing your own text.
2
Decide whether visuals help
A filmed demonstration, illustrated story, or speaker's expression can add meaning that audio alone does not carry. For proofreading a paragraph or reviewing notes, those visuals may be beside the point. Try following one short section while listening: if you keep returning to the page to inspect specific words, choose a route that keeps the text close at hand.

Check control and permission
With text-based narration, you choose which passage to work from; available playback controls depend on the reader you use. On YouTube, the uploader decides what appears in the video, though viewers can use the playback options YouTube offers. Before posting a narrated video, check your rights to the source text, images, music, and any recording you include.
