Bill, I just discovered that between 0:43 and 0:45 of your video "hi, i'm steve," the bird that delivers the mail "steve" [or whatever his name actually is] exits the screen during frames 1,1080-1,111 (according to QuickTime Player on my MacBook Pro).  At frame 1,112, or the next frame, the bird reappears on the screen and re-exits the screen in the following frames.  Was that an unintentional glitch,
yes
