An Example for Class

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.



Google writes that Youtube now auto captions. I’ll probably test that later this weekend. I did want to show what adding auto captions did with an existing video.

Look for this screen to start your auto captioning.

It sort of got the words right . . .

I edited some of the captions to show I could. I’m not actually using this in class so I wasn’t very concerned about perfection. I corrected the first minute and 3 seconds in about 5 minutes. I left the rest wrong to give a sense of what needs fixing. Writing a script and recording this video took around 20 minutes. Captioning would take about another 20, although it might get quicker if I learned to speak slower and use the editor more efficiently. It does make the video viewable on a bus for students though.

Turn on captions and enjoy (especially the last 3 minutes).
