I'm Dan and this is my blog. I'm a former high school math teacher and current head of teaching at Desmos. He / him. More here.


  1. I’d wager you could hack something together in FCP. I know it supports timecodes. (I forget if they do base 100 or not.) The counters are going to be really painful, though.

    Oh man, I needed this a few days ago when I was teaching myself how to make transparent timers and counters in After Effects and utilizing them in Premiere Pro! Now it’s time to shoot some 60fps video and get to playing over the summer. Love the work Dan, especially the tutorials.

    I need to get my hands on AfterEffects! IMovie just isn’t cutting it anymore. What software do you use to screen capture?
