A student asked a question, so I made a real video. I noticed two things. Even after I thought I made clean corrections there were still errors. None seem too horrible though. The other thing I noticed is that math translation is hard. Not only are variables sometimes interpreted as words, numbers are sometimes written as Arabic numerals and sometimes spelled out. I am not sure if there is a way this is supposed to be done. In future videos I will probably try to make it look as much like the equation on the screen as I can.
Auto-captioning does help a little, but correcting Youtube captions did double my production time.
I also am now linking to Youtube instead of directly publishing the videos. That means there are ads after my video plays. Eventually I can save some money by downgrading my WordPress plans to ones that don’t have direct video upload. But, the students pay the cost through the ads.
