1/28 Class Blog

Hey class,

Sorry it took me two days to get this up -- we dance majors have a show coming up and rehearsals have been wild. Anyway, here are the notes I took during class along with some vocabulary and the homework assignments. Comment if I left anything out or unexplained. Have a great week!

- ^Find at least 3-4 videos (or make them): 30-60 seconds long

** Use .MOV Quicktime files only, use Photo Jpeg codec (the codec is called Photo Jpeg) We use .PNG codec for photo because it uses alpha; we use Photo Jpeg codec for video because it turns every frame into a viewable still photo; it's also compatible with everything (Windows, Mac, Linux)
