Youtube captions are pretty easy to do and their auto captions aren't bad - usually just needs a bit of light editing. If you've already got timed captions done you can usually just upload the file and it will sort itself out

Thank you. For some reason I couldn’t find the auto captions, and so did them manually! Am interesting experience, but will look for the auto ones to edit next time (that’s what I’m used to doing on Panopto for work things - my work rather than my husband’s…)
