I misspoke in the middle of a video I uploaded to YouTube and I'd like to insert a text annotation into the video (at that point) to clarify the error.
I've already posted the video-link to a forum for the parties who will be watching it, so I'd like to achieve this annotation without invalidating that link (which is what would happen if I removed the video, added the annotation offline, and re-uploaded it.)
Is it possible, using the editor provided by YouTube, to insert a text annotation at any arbitrary point?
The tutorials I've found, regarding this task, are outdated and no longer work.
