Once we were able to find to people that play the roles of Alicia Keys and the male we made a schedule of what days we will be able to film and what scenes we would film as well, but obviously things such as the weather and whether or not people are available and if we have available houses to film in. We made sure we filmed all of the indoor scenes on days when the weather inst the best and outdoor scenes on days when the weather wasn't to bad.
Once we started filming we filmed most of the song we could on whatever day people were available and started editing whatever amount of footage we had, after a while we realized we didn't have enough footage of lip syncing which meant we had to go back and do more filming of lip syncing. Then we would be able to continue editing with the new footage which has her lip syncing.
We are currently in the process of still filming and editing whenever we get new footage.
