If you click on the “English – Automatic Captions” button, YouTube auto-generates caption text.

If you click “Download,” YouTube gives you a file called captions.sbv. This can be opened and edited in Notepad/TextEdit.

You can then listen to the video, editing text for accuracy and capitalization.
