1) The filming equipment they brought included a low quality video camera, a large tripod, and a glide cam for spinning shots, however the glide cam was missing weights and screws so they couldn't use it. 2) They used Premier Pro for editing but found it challenging as the software was still new, so Charlotte did most of the editing and taught skills like slowing clips. 3) For sound and music, the document author was experienced with Mixcraft and created music and effects, teaching Charlotte as well, allowing them to collaborate effectively.
