It allows 4 types of export: CD JPEG, CD AVI, SD JPEG, and SD AVI. I know enough to know that JPEG is a still image, so I haven't chosen that. After I choose one of the AVI options I am brought to a menu screen with the following options:
*Video Mode (where I can choose Full or CIF)
*Audio Mode (where I can choose Right, Left, or Disable)
*Time (where the SD allows me to from 10 seconds to 90 seconds in 5 second intervals and the CD allows me to go from 10 seconds to 10 minutes)
*Save (where it starts the transfer)
I can't imagine the 2GB SD getting filled after 90 seconds, but I'm not certain. The manual for the EDVR indicates it will transfer up to 30 minutes onto a CD. It doesn't indicate any limit on SD cards.
